Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
As shown in fig. 1, a bulletproof glass security film provided for an embodiment of the present invention includes: the composite membrane is prepared by combining ultrahigh molecular weight polyethylene and epoxy resin.
The bulletproof glass safety film is a safety film which is 0.28mm in total thickness, is transparent by 90%, is ultraviolet-proof and electromagnetic-proof, can achieve the functions of ultraviolet resistance, electromagnetic signal resistance and the like by adding different materials (such as an ultraviolet-proof agent and a radiation-proof agent) to an ultra-high molecular weight polyethylene rolled membrane, and is a polyurethane system with a pressure-sensitive adhesive as an adhesive layer 2. The ultra-high molecular weight polyethylene calendered membrane is an ultra-high molecular weight polyethylene composite material or an ultra-high molecular weight polyethylene fiber material; the pressure-sensitive adhesive is a polyurethane system, and the adhesive strength is greater than 15N.
According to the embodiment of the invention, on the premise of keeping higher breaking strength, the elasticity modulus of the UHMWPE calendered membrane is far greater than that of a fiber material, the high elasticity modulus is very favorable for shock wave conduction, the stress concentration phenomenon is avoided, and the bulletproof grade can be improved. In addition, the two layers of pressure-sensitive adhesives have different bonding strengths, and when the pressure-sensitive adhesives are subjected to impacts with different properties, micro-displacement with different forms occurs, and base films with different laminates can also stretch to different degrees. The micro-displacement and the stretching of the diaphragm prolong the acting path of the impact force, effectively weaken the impact strength and finally relieve the impact by the displacement. The safety film is only adhered to one surface of the glass, so that the safety film has a one-way protection function. After the safety film is installed, the side provided with the safety film is made irrevocable.
The special structural design is adopted in the figure 1, so that the energy can be effectively absorbed at the moment of loading, the bulletproof capability is strong, and the ultra-high molecular weight polyethylene calendered membrane is not easy to tear.
The embodiment of the invention can prevent the glass from being excessively distorted, the bulletproof glass safety film is attached to the reverse side of the impacted surface of the glass, and when the glass is impacted, the glass is pulled through the safety film to prevent the glass from being distorted. So that the common glass has certain bulletproof and penetration-proof functions. After the bulletproof glass safety film disclosed by the embodiment of the invention is pasted, the bulletproof capability is greatly improved.
In the embodiment of the invention, a plurality of layers of rolled membranes are superposed (rolled membrane + adhesive layer + rolled membrane), and high light transmission is ensured by controlling the thickness and high light transmission materials.
In order to further provide the bulletproof performance, other special structural layers are added in the embodiment, and the method comprises the following steps:
as shown in fig. 2, another bulletproof glass security film provided by the embodiment of the invention is provided, and as shown in fig. 2, a metal mesh is arranged in the bonding layer. When the bullet strikes the radiation-proof outer layer 1 and the noise reduction outer layer 2, the bullet passes through the buffer area in the isolation ring 3 and acts on the metal net 4, the metal net 4 deforms to offset the kinetic energy of a part of bullets, and meanwhile, the metal net can play a role in preventing electromagnetic radiation.
Two adjacent ultra-high molecular weight polyethylene calendered membranes are connected through a resin material, and the resin material comprises polyvinyl alcohol or thermoplastic polyurethane elastomer rubber. The shape of the resin material may be an oval, an X-shaped or a Y-shaped structure.
Utilize vertical resin material to carry out firm connection with calendering diaphragm, adhesive linkage, metal mesh, carbon fiber fabric layer, when receiving the impact, there is little deformation or aversion between the two-layer structure between each resin material, is equivalent to there is certain buffer capacity, especially to non-forward load, and the effect of buffering energy-absorbing is more obvious, has guaranteed the integrality of structure, and the rupture disk is difficult for being destroyed.
