The technical solution of the present invention will be further described with reference to the following embodiments and the accompanying drawings.

Example one

Referring to fig. 1, a transparent assembly 10 according to a first embodiment of the present invention includes a first glass layer 1, a radiation protection layer 3 and a second glass layer 7, wherein the radiation protection layer 3 includes a first surface 31 and a second surface 32 opposite to each other, the first surface 31 is bonded to the first glass layer 1 by a first adhesive layer 2, the buffer layer 5 includes a third surface 51 and a fourth surface 52 opposite to each other, the third surface 51 is bonded to the second surface 32 of the radiation protection layer 3 by a second adhesive layer 4, and the second glass layer 7 is bonded to the fourth surface 52 of the buffer layer 5 by a third adhesive layer 6.

According to the transparent component 10 of the first embodiment of the present invention, since the transparent component 10 includes the radiation protection layer 3 and the buffer layer 5, the radiation protection layer 3 can be used to protect the radiation, and the buffer layer 5 can also be used to prevent the radiation protection layer 3 and the second glass layer 7 from being damaged due to the large thermal stress caused by the different materials.

It can be understood that, because the transparent component 10 has the ray protection layer 3, when the transparent component 10 is applied to a scene with rays, the damage of the rays to a human body can be effectively relieved. For example, when the transparent component 10 is applied to a medical device, the transparent component 10 can be used as a transparent window of the medical device, or can be used as a transparent window of a place where the medical device is placed, so that a user can observe through the window conveniently, rays can be blocked effectively, and damage of the rays to a human body is relieved.

Of course, the transparent member 10 may also be applied to a vehicle, an airplane, etc. as a window glass of the vehicle, the airplane, etc. so that the vehicle, the airplane, etc. can effectively block rays, so that the vehicle, the airplane, etc. can be applied to a place with rays.

In some embodiments, the radiation-shielding layer 3 is doped with a high atomic number element capable of absorbing radiation, the high atomic number element includes at least one of lead, lanthanum, bismuth, thallium and tungsten, and the doping amount of the high atomic number element is not less than 61% by mass in the γ -ray-shielding layer 3. Thus, the ray protection layer 3 can effectively shield rays, particularly gamma rays, so as to effectively relieve the injury of the gamma rays to human bodies.

Optionally, the radiation protection layer 3 is an organic glass layer or an inorganic glass layer. When the radiation protection layer 3 is a plexiglas layer, the mass of the plexiglas layer is relatively light, so that the overall mass of the transparent component 10 is relatively light. However, since the compatibility of the high atomic number element with the organic material is low, the amount of the high atomic number element which can be doped in the organic glass layer with the same volume is small, and specifically, when the organic glass layer is adopted as the radiation protection layer 3, the density is 2.2 × 103kg/m3, and the shielding effect is not ideal. If a better shielding effect needs to be achieved, the volume of the organic glass layer needs to be increased, so that the doping amount of the high atomic number element is increased, and thus the transparent component 10 has a larger volume and is not beneficial to installation.

Based on this, the ray protection layer 3 can be an inorganic glass layer, and the high atomic number element can enter into the network structure of the inorganic glass, so that the density of the gamma ray protection layer 3 is 4.0 × 103kg/m 3-5.5 × 103kg/m3, thus, the doping amount of the high atomic number element of the inorganic glass with the same volume is larger, and the shielding capability is obviously improved. Illustratively, the density of the gamma ray protection layer 3 may be 4.0 × 103kg/m3, 4.2 × 103kg/m3, 4.4 × 103kg/m3, 4.6 × 103kg/m3, 4.8 × 103kg/m3, 5.0 × 103kg/m3, 5.5 × 103kg/m 3.

Optionally, the thickness of the radiation protection layer is less than or equal to 12mm, so that on the basis of effectively realizing radiation protection, the problem that the overall thickness of the transparent component 10 is thick due to the excessively thick thickness of the radiation protection layer 3 can be avoided.

Further, as can be seen from the foregoing, since the radiation protection layer 3 is mainly used for protecting radiation, and the material of the radiation protection layer 3 is different from that of the second glass layer 7, the radiation protection layer 3 and the second glass layer 7 have different thermal expansion coefficients, so that the radiation protection layer 3 is easily broken by thermal stress. Accordingly, by providing the buffer layer 5 between the radiation protection layer 3 and the second glass layer 7, thermal stress between the radiation protection layer 3 and the second glass layer 7 is buffered by the buffer layer, and thus the radiation protection layer 3 can be prevented from being damaged due to concentration of thermal stress.

Specifically, the buffer layer 5 may be provided in multiple layers, so that the thermal stress generated during the lamination process of the transparent component 10 can be transferred between the buffer layer 5 and the second glass layer 7, which not only can protect the radiation protection layer 3, but also can provide better flatness to the laminated transparent component 10.

It is considered that when the transparent component 10 is applied to a low-temperature scene, for example, when the transparent component 10 is applied to a space shuttle, the inner surface of the transparent component 10 (i.e., the side where the second glass layer 7 is located is the inner surface) is easily fogged due to the high temperature inside the cabin and the low temperature outside the cabin, and thus the visual effect of the transparent component 10 is affected. Based on this, in some embodiments, the third surface or the fourth surface of the buffer layer 5 is provided with the defogging layer 8. Thus, the fog generated by the transparent component 10 can be effectively alleviated, and the object viewing effect can be improved.

Optionally, the defogging layer 8 includes one or more of a conductive film layer, a heating wire, and a metal grid. Like this, can be when realizing the light transmissivity of transparent subassembly 10, the accessible is switched on in order to realize the defogging to transparent subassembly 10 to defogging layer 8, and defogging effect preferred, and be convenient for set up defogging layer 8 in buffer layer 5's internal surface or surface.

In some embodiments, it can be seen that the first glass layer 1 is made of inorganic glass, which has high strength, so that when the transparent component 10 is used, for example, when the transparent component 10 is applied to some special scenes, such as windows of vehicles for transporting missiles, bombers for carrying special weapons, space shuttles, etc., the first glass layer 1 of the transparent component 10 can be disposed toward the outside of the cabin, and the second glass layer 7 can be disposed toward the inside of the cabin, in other words, the outer surface of the first glass layer 1 serves as the outer surface of the transparent component 10, the inner surface of the second glass layer 7 serves as the inner surface of the transparent component 10, and the inner surface of the first glass layer 1 is disposed opposite to the outer surface of the second glass layer 7, which is favorable for achieving better defense effect.

In some embodiments, first glass layer 1 may comprise at least one of a soda lime silica glass, a high alumina glass, a lithium aluminosilicate glass, a borosilicate glass. Thus, the first glass layer has better structural strength so as to realize better defense effect.

Alternatively, the thickness of the first glass layer 1 is 1.5mm or more and 4mm or less, and exemplarily, the thickness of the first glass layer 1 may be 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, or the like. In this way, the structural strength of the first glass layer 1 can be ensured, while at the same time ensuring that the first glass layer 1 has a suitable thickness, so that the transparent component 10 can be provided with a suitable thickness for ease of use. When the thickness of the first glass layer 1 is less than 1.5mm, the structural strength of the first glass layer 1 is small, and it is difficult to satisfy the defensive requirement. When the thickness of the first glass layer 1 is more than 4mm, the thickness of the first glass layer 1 is thick, which makes the thickness of the transparent member 10 thick, inconvenient to install and also results in a large mass of the transparent member 10, which increases the load of the vehicle or airplane when the transparent member 10 is applied to the vehicle or airplane.

It is understood that, in some usage scenarios of the transparent element 10, the transparent element 10 is in a cold environment, and therefore, the transparent element 10 is required to have a heating function, and based on this, in some embodiments, the surface of the first glass layer 1 may be plated with a first transparent conductive film, for example, an ito film, a au film, a ag composite film, etc., and the first transparent conductive film is heated by applying electricity to the first transparent conductive film, so as to heat the transparent element 10. Optionally, the first transparent conductive film may be plated on a surface of the first glass layer 1 facing the second glass layer 7 or a surface of the first glass layer facing away from the second glass layer 7, and a plating position of the first transparent conductive film may be set according to specific needs, which is not specifically limited in this embodiment.

In order to facilitate controlling the first transparent conductive film to be powered on or off, optionally, the transparent assembly 10 may further include a temperature sensing element, such as a temperature sensing element, a thermistor, or the like, the temperature sensing element may be disposed between the first glass layer 1 and the second glass layer 7 to sense the temperature of the transparent assembly 10 through the temperature sensing element, and the temperature sensing element may be further connected to a temperature control system to facilitate controlling the first transparent conductive film to be powered on or off automatically to perform heating or stop heating.

Specifically, the temperature sensing member may be disposed on a side of the first adhesive layer 2 adjacent to the first glass layer 1. Utilize first tie coat 2 to set up temperature-sensing spare, need not additionally to occupy the space between first glass layer 1 and the second glass layer 7 again, need not to set up extra tie coat moreover and bond.

In some usage scenarios, such as the transparent component 10 on a vehicle for transporting missiles, a bomb aircraft carrying special weapons, a space shuttle, and the like, the transparent component 10 is also required to have a stealth function, and based on this, in some embodiments, the surface of the first glass layer 1 may be further coated with a second transparent conductive film layer, such as an indium tin oxide film, a gold film, a silver composite film, and the like, and a protective film layer, such as an SiO2 film, a diamond-like film, and the like, on the second transparent conductive film layer. In this way, the second transparent conductive film is plated, thereby realizing the stealth function of the transparent component 10.

It is understood that a first transparent conductive film and a second transparent conductive film are respectively plated on two surfaces of the first glass layer 1, and exemplarily, the first transparent conductive film is plated on a surface of the first glass layer 1 facing the second glass layer 7, and the second transparent conductive film is plated on a surface of the first glass layer 1 facing away from the second glass layer 7. Thus, the transparent member 10 can have a better stealth effect and a better heating effect.

In some embodiments, as can be seen from the foregoing, the second glass layer 7 is disposed on the inner side of the transparent component 10, that is, the second glass layer 7 does not need to directly contact with the external environment compared to the first glass layer 1, and therefore, the requirement on the strength of the second glass layer 7 is small, the second glass layer 7 may be an inorganic glass layer, and may also be an organic glass layer, and in order to reduce the cost of the second glass layer 7 and reduce the weight of the second glass layer 7, the second glass layer 7 may be an organic glass layer, for example, the second glass layer 7 may be one or more of a polycarbonate plate, an oriented organic glass plate, and a polyurea plate, so that the second glass layer 7 can have excellent structural strength and good light transmittance. As can be seen from the above, the radiation protection layer 3 is an inorganic glass layer, and the difference between the thermal expansion coefficients of the radiation protection layer 3 made of an inorganic material and the second glass layer 7 made of an organic material is very large, so that the thermal matching between the radiation protection layer 3 and the second glass layer 7 is poor, and therefore, by providing the buffer layer 5, the problem of thermal stress between the radiation protection layer 3 and the second glass layer 7 can be effectively solved.

In order to adapt to the visual effect of the highlight places, the transparent component 10 optionally further comprises a highlight protection layer 11, the highlight protection layer 11 is arranged on the surface of the second glass layer 7, and the highlight protection layer 11 comprises one or more of forward liquid crystals, trans liquid crystals, polarizing plates and micro-electro-mechanical systems. Through setting up highlight inoxidizing coating 11, can effectively alleviate the damage of highlight to the people. By adopting the forward liquid crystal, the trans liquid crystal, the polaroid or the micro-electromechanical system as the strong light protective layer 11, when strong light irradiation is received, the transmittance can be quickly reduced, particularly, the transmittance of the transparent component 10 can be reduced to below 10% in 10ms, so that the damage of strong light to people is greatly relieved.

Referring to fig. 2, in view of the fact that the application scenario of the device such as a vehicle for transporting missiles, a bomb aircraft carrying special weapons, a space shuttle, etc. may not only have gamma rays, but also have electromagnetic waves, especially high-frequency electromagnetic waves, which are harmful to human body, in some embodiments, the transparent component 10 further includes at least one electromagnetic shielding layer 9, and the electromagnetic shielding layer 9 is disposed in one or more of the first adhesive layer 2, the second adhesive layer 4, and the third adhesive layer 6. The electromagnetic wave can be effectively shielded by arranging the electromagnetic shielding layer 9, so that the transparent component 10 can transmit light to see objects, and simultaneously can shield gamma rays and electromagnetic waves so as to reduce the damage of the gamma rays and the electromagnetic waves to human bodies.

Illustratively, one or more electromagnetic shielding layers 9 may be disposed in the first adhesive layer 2, or one or more electromagnetic shielding layers 9 may be disposed in the second adhesive layer 4 or the third adhesive layer 6, so that electromagnetic shielding can be achieved by the electromagnetic shielding layers 9.

Of course, it can be understood that one or more electromagnetic shielding layers 9 may be disposed in the first adhesive layer 2, the second adhesive layer 4, and the third adhesive layer 6, so that the transparent assembly 10 has better electromagnetic shielding effect and can be applied to occasions with higher requirements on electromagnetic shielding effect.

In some embodiments, the electromagnetic shielding layer 9 comprises at least one of graphene, metal mesh, silver nanowires. In this way, the electromagnetic shielding layer 9 can not only shield electromagnetic waves, but also shield electromagnetic pulses, and in addition, the electromagnetic shielding layer 9 can shield electromagnetic frequencies with a wider band, specifically, the electromagnetic shielding layer 9 can shield electromagnetic waves and electromagnetic pulses with frequencies of 30MHz to 40GHz, the electromagnetic shielding effect is good, especially, the electromagnetic waves with frequencies of 40GHz are greatly damaged to the human body, and the electromagnetic shielding layer 9 can effectively shield the electromagnetic waves with frequencies of 40GHz, so that the damage of the electromagnetic waves to the human body can be greatly reduced.

It is understood that the metal grid refers to a metal grid structure formed by plating a metal layer on an organic thin film and by laser etching. The silver nanowire is a silver nanowire film with an electromagnetic shielding effect, and the silver nanowire film can be obtained by drying a silver nanowire solution, and it can be understood that the silver nanowire can also be prepared in other manners.

Optionally, the transmittance of the electromagnetic shielding layer 9 is greater than or equal to 80%, and/or the haze of the electromagnetic shielding layer 9 is less than or equal to 2%. Illustratively, the transmittance of the electromagnetic shielding layer 9 may be 80%, 85%, 90%, 95%, etc., and the haze of the electromagnetic shielding layer 9 may be 0.5%, 1%, 1.5%, 2%, etc. Transmittance through limiting the electromagnetic shielding layer 9 is greater than or equal to 80%, and haze of the electromagnetic shielding layer 9 is less than or equal to 2%, so that the transmittance of the electromagnetic shielding layer 9 can be ensured, and further, the transmittance of the transparent component 10 is ensured, so that the transparent component 10 has better visual properties.

In some embodiments, the first adhesive layer 2 has a thickness of 5mm to 8mm, or the second adhesive layer 4 has a thickness of 1.5mm to 4mm, or the third adhesive layer has a thickness of 1.5mm to 4 mm. Illustratively, the first adhesive layer may have a thickness of 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 5.5mm, 8mm, etc., the second adhesive layer 4 may have a thickness of 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc., and the third adhesive layer may have a thickness of 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc. By limiting the thicknesses of the first bonding layer 2, the second bonding layer 4 and the third bonding layer, the bonding strength between the first bonding layer and the first glass layer 1 and the gamma-ray protective layer 3, the bonding strength between the second bonding layer and the gamma-ray protective layer 3 and the buffer layer 5, and the bonding strength between the third bonding layer 6 and the buffer layer 5 and the second glass layer 7 can be ensured. In addition, it is possible to avoid a case where the thickness of the entire transparent member 10 is excessively thick due to an excessively thick adhesive layer.

Optionally, the elongation at break of the first adhesive layer 2 is greater than or equal to 200%, or the glass transition temperature of the first adhesive layer 2 is less than or equal to-20 ℃, or the elongation at break of the second adhesive layer 4 is greater than or equal to 200%, or the glass transition temperature of the second adhesive layer 4 is less than or equal to-20 ℃, or the elongation at break of the third adhesive layer is greater than or equal to 200%, or the glass transition temperature of the third adhesive layer is less than or equal to-20 ℃. Illustratively, the elongation at break of the first adhesive layer 2 may be 200%, 400%, 500%, 700%, 800%, the glass transition temperature of the first adhesive layer 2 may be-20 ℃, -30 ℃, -40 ℃, -50 ℃, the elongation at break of the second adhesive layer 4 may be 200%, 400%, 500%, 700%, 800%, the glass transition temperature of the second adhesive layer 4 may be-20 ℃, -30 ℃, -40 ℃, -50 ℃, the elongation at break of the third adhesive layer 6 may be 200%, 400%, 500%, 700%, 800%, the glass transition temperature of the third adhesive layer 6 may be-20 ℃, -30 ℃, -40 ℃, -50 ℃. In this way, the elongation at break and the glass transition temperature of the first adhesive layer 2, the second adhesive layer 4, and the third adhesive layer 6 are limited, so that the first adhesive layer 2, the second adhesive layer 4, and the third adhesive layer 6 have good toughness and can be adapted to a low-temperature environment.

Alternatively, the first adhesive layer 2, the second adhesive layer 4, and the third adhesive layer 6 may include at least one of a PU (Polyurethane) film, a PVB (polyvinyl butyral) film, and an SGP (high strength glass intermediate film) film. In this way, the first adhesive layer 2, the second adhesive layer 4, and the third adhesive layer 6 can be ensured to have high toughness and can be applied to a low-temperature environment.

When the first bonding layer 2, the second bonding layer 4 and the third bonding layer 6 adopt PVB films, the breaking elongation of the first bonding layer 2, the second bonding layer 4 and the third bonding layer 6 can reach more than 200%, and the glass transition temperature can reach below-20 ℃.

When the first bonding layer 2, the second bonding layer 4 and the third bonding layer adopt PU films, the elongation at break of the first bonding layer 2, the second bonding layer 4 and the third bonding layer 6 can reach more than 700 percent, and the glass transition temperature can reach below minus 50 ℃.

In the transparent component 10 according to the first embodiment of the present invention, since the transparent component 10 includes the radiation protection layer 3 and the second glass layer 7 disposed between the radiation protection layer 3 and the second glass layer 7, while realizing radiation, it is possible to avoid a situation in which the radiation protection layer 3 is easily damaged due to a difference in thermal expansion coefficient between the radiation protection layer 3 and the second glass layer 7. In addition, because the transparent component 10 is also provided with the electromagnetic shielding layer 9, the transparent component 10 not only can radiate rays, but also can shield electromagnetic waves, so that the transparent component 10 integrates multiple functions, and has strong applicability to some special scenes.
