Detailed Description of the Invention

[Technical field and industrial applicability of the invention]
The present invention generally relates to multilayer acoustic and thermal insulator liners that can be used to insulate the environment, for example, the passenger compartment of a vehicle, from the heat and sound generated by the vehicle's mechanical components during operation of the vehicle. . Other applications include soundproofing and insulation of electrical appliances such as dishwashers and clothes dryers, ovens, air conditioning units and pipes in buildings including homes, offices and industrial structures.

BACKGROUND OF THE INVENTION
Soundproofing materials are well known in the art. In order to mute, the soundproofing material typically utilizes both sound absorption, that is, the function of absorbing incoming sound waves and transmission loss, that is, the function of reflecting incident sound waves. One of the applications in which such soundproofing materials are widespread is that the engine compartment, fire barrier, fender well, door, floor pan, and other parts of the passenger compartment shell provide passenger convenience and comfort. This is an automotive field in which soundproofing processing is usually performed to reduce road surface noise.

  Mats made of heat-resistant glass fibers can also be used, for example, (a) on the fire wall between the dashboard and engine compartment and (b) the vehicle floor between the passenger cabin and the driveline (power transmission system) and exhaust system. It is used along bread. These materials allow thermal insulation that allows a low and comfortable temperature to be maintained in the operator / passenger cabin, especially during summer. In addition, these materials provide the required degree of sound insulation and reduce various mechanical noises in the suspension and tires when motors, drivetrains and vehicles are traveling on rough and often rough surfaces of the road. I'm letting or missing.

  Various methods for producing or producing such a soundproofing material and heat insulating material are known in the art. Examples of these methods include, for example, U.S. Pat. No. 5,055,341 (hereinafter referred to as “Yamaji et al. Patent”), U.S. Pat. No. 5,501, assigned to Fotinger et al. No. 898 (hereinafter referred to as “Fotinger et al.”), US Pat. No. 3,652,377 granted to Helmic and US Pat. No. 5,591,289 granted to Soda et al. It is described in.

In Yamaji et al., A woven fabric and / or a non-woven fabric is attached to a composite material of a fiber and a thermoplastic resin. The Fottinger et al. Patent discloses a multi-layer, multi-density composite containing polyester fibers. The fiber is preheated to a temperature above the melting point of the fiber in a furnace by a metal plate. The nonwoven fibrous layer is loaded into a molding tool and subjected to molding pressure for a residence time sufficient to complete the molding process. Next, the component is cooled below the softening temperature of the fiber to fix the composite material in the final molded product.
Helmic U.S. Pat. No. 3,652,377 teaches a method of forming a two-layer fibrous pad with a different density in each of the layers. Specifically, it is taught to form a pad by subjecting two layers to a series of compression and heating operations to successively produce various desired different densities in the layers. In a preferred embodiment, the final product is approximately 3 to 3.5 pounds / cubic foot (48 to 56 kg / m ³ ) and 1/8 inch thick (3.175 mm) adjacent to one major surface. Adjacent to the first high-density layer and the first layer, a second low of about 1 pound / cubic foot (16 kg / m ³ ) and a thickness of 7/8 inch (22.2 mm) A thermosetting resin-bonded entangled glass fiber having a density layer is a 1 inch (25.4 mm) thick pad.
In US Pat. No. 5,591,289 to Soda et al., An automobile passenger composed of an inner portion of a non-woven high loft bat of thermoplastic material joined to each side by bat materials each having a different density A fibrous headliner for a room is taught. To form the headliner, a high-density bat is heated and coated with a thermoplastic resin, and the entire headliner is sandwiched in a suitable molded structural member and cured with heat.

  Various additional examples of soundproofing materials generally used for vehicle applications are given in US Pat. No. 5,298,694 (hereinafter referred to as “Thomson et al. Patent”), Sanokki, etc., granted to Thomson et al. US Pat. No. 5,624,726 (hereinafter referred to as “Sanocchi et al. Patent”), US Pat. No. 5,759,659 granted to Sanokchi et al. (Also referred to as “Sanocchi et al. Patent”) In the specification and U.S. Pat. No. 5,961,904 (hereinafter referred to as “Swan et al. Patent”).

The Thomson et al. Specification discloses a second layer, such as a scrim nonwoven film or foil, applied to the nonwoven fabric for protection by a nonwoven soundproof web and a water barrier of thermoplastic fibers.
Sanokki et al. Describes a ceramic paper and ceramic fiber fabric encapsulated in a heat-sealable thermoplastic polyolefin that serves as a soundproof layer and a moistureproof layer made of fibrous soundproof material, foam-like soundproof material, or a combination thereof. And a soundproof blanket in the form of a composite with a heat-resistant layer of glass fiber fabric, ceramic nonwoven scrim or glass fiber nonwoven scrim.

  The Swan et al. Patent discloses a nonwoven soundproof web of heat stabilized meltblown polypropylene microfibers which also contains staple fibers such as crimped bulking fibers and / or binder fibers. The soundproof web is formed as a laminate with a water barrier layer of flat thermoplastic polyolefin film, such as polyethylene film, polypropylene film and ethylene propylene copolymer film.

  In other cases, manufacturers utilize one or more layers of ethylene vinyl acetate and / or polyvinyl chloride to obtain the desired moisture barrier. The added water barrier layer often adds significant weight to the soundproofing product. This is a huge drawback for vehicle manufacturers seeking to reduce total vehicle weight and promote fuel savings.

  In many soundproofing applications, particularly in soundproofing applications associated with automobiles, water barrier protection is a critical consideration. As shown by these prior art patent specifications, it has been found that it is generally necessary to add protection means by a water barrier to the soundproofing material. This is because this soundproofing material would otherwise be so permeable to water that it would allow water to enter. For this purpose, it is common practice to provide a laminated structure that is effective for its intended purpose but has several drawbacks. Specifically, delamination generally occurs as a result of handling and operation during installation and / or the deterioration and degradation effects of various environmental factors over time. This delamination typically impairs the effectiveness of the water barrier, thereby potentially causing undesirable water intrusion due to penetration and capillary action. Therefore, an improvement that improves soundproofing and thermal insulation properties and enables reliable water barrier protection over a long useful life in all lightweight products suitable for use in compact vehicles and even more compact vehicles There is a need for a mold insulation method.

Reference will now be made in detail to the presently preferred embodiments of the invention, which are illustrated in the accompanying drawings.

Detailed Description of the Invention and Preferred Embodiments
Referring now to FIG. 1, FIG. 1 shows a first embodiment of an insulator type liner (liner also serving as an insulator) of the present invention, indicated as a whole by 10. The insulator type liner 10 has a pad 12 made of fiber material. The fiber material comprises (a) a thermoplastic polymer staple fiber and a thermoplastic conjugate (two-component) fiber, (b) a glass staple fiber and a thermoplastic conjugate fiber, (c) a combination of (a) and (b) above It is good to have the form. The thermoplastic staple fiber and conjugate fiber may be selected from the group consisting of, but not limited to, polyester, polyethylene, polypropylene, polyethylene terephthalate, and any mixtures thereof. Examples of the glass fiber include E glass, S glass, and basalt fiber. Natural fibers (eg cannabis, kenaf) can also be used.

The pad 12 has a bulky soundproof portion 14 having a density of substantially 8.0 to 80.0 kg / m ³ and a skin layer 16 having a relatively high density provided along one face thereof. The skin layer 16 has a thickness of substantially 0.25 to 10.0 mm and a density of substantially 32.0 to 1600.0 kg / m ³ . The density of the skin layer 16 may be substantially constant throughout its thickness, or may vary gradually from a maximum density along its outer face to a higher density than that of the soundproof portion 14 along its inner portion. You may do. When the density of the skin layer 16 changes, the average density of the skin layer falls within the indicated range.

  In accordance with an important feature of the present invention, the pad 12 having both a relatively low density soundproof portion 14 and a relatively high density skin layer 16 is formed from a single integral sheet of fibrous starting material. Accordingly, the pad 12 is a non-laminated product, and therefore the skin layer 16 does not tend to delaminate from the soundproof portion 14 under any environmental conditions that the insulator liner may be subjected to. The skin layer 16 provides additional mechanical strength and rigidity to the pad 12 to aid in the handling of the insulator liner 10 during installation of a soundproofing device or part, such as a body component, furnace or air conditioning unit housing or conduit. Given to.

  In many applications, the skin layer 16 serves to maintain the integrity and soundproofing and thermal insulation performance of the insulator liner 10 over a long useful life. Specifically, the skin layer 16 becomes an extra mechanical support. In addition, the increased density of the skin layer 16 plugs the pores of the material, thereby eliminating the potential for many potential environmental contaminants that could otherwise degrade the performance of the insulator liner over time. Permeability is obtained. Thus, the skin layer 16 effectively serves to protect the soundproof portion 14 as a laminated surface finish in a manner substantially similar to conventional insulator type liner designs. Such conventional surface finish layers inherently have a risk of peeling and breaking. This is a major drawback considering the harsh operating environment where such liners and insulators are often exposed. Advantageously, the present invention eliminates this risk of delamination that can potentially lead to insulator liner failure.

  As shown in FIG. 2, another embodiment of the insulator-type liner 10 has a pad 12 with a bulky soundproof portion 14 and a skin layer 16 as described above for the embodiment of FIG. In addition, the embodiment of FIG. 2 has a second skin layer 18 deposited along the face opposite the pad 12. The second skin layer 18 may have the same physical attributes as described above for the first skin layer 16. However, the two skin layers 16, 18 may differ in thickness and / or density within the indicated range.

  As shown in FIG. 3, another embodiment of the insulator-type liner 10 has a pad 12 with a bulky soundproof portion 14 and a skin layer 16 as described above with respect to the other embodiment of FIG. In this embodiment, the pad face 20 opposite the skin layer 16 includes a surface finish layer 22. The surface finish layer 22 may be made from polyester, rayon, metal foil and any mixture thereof. Such a surface finish layer 22 can be used for aesthetic purposes, decorative purposes or practical purposes such as heat reflection or heat dissipation.

  Yet another possible embodiment of the present invention is shown in FIG. The insulator liner of FIG. 4 has a pad 12, a bulky soundproofing 14 and a skin layer 16 just as described above for the embodiment of FIG. In addition, the insulator-type liner 10 has a first surface finish layer 24 covering the skin layer 16 and a second surface finish layer 26 covering the face 28 opposite to the pad 12. The two surface finish layers may be made from polyester, rayon, metal foil and any mixture thereof. Of course, multilayer surface finishes can also be used.

  For applications that require good thermal insulation, the surface finish layers 22, 24 and / or 26 are made from a heat reflective material, such as a metal foil (eg, aluminum or other heat reflective metal). Is good. When using a metal foil, the thickness of the foil is generally 0.25 to 7.5 mm. The thickness chosen is based on the temperature, durability and structural requirements of the specific product application.

  The surface finishing layers 22, 24 and / or 26 may be reinforced or unreinforced. Stiffeners are provided to increase durability and structural integrity. The reinforcement may be in the form of a fibrous scrim, a fibrous mat or a fibrous web. For many applications, the reinforcement is made from relatively strong fibers, such as glass fibers. Typically, glass fiber threads are arranged in a cross pattern. Adjusting the number of yarns per inch can provide the desired product characteristics. The fiber reinforced strands are provided at regular intervals over the web longitudinal direction and the web transverse direction of the foil. Typical spacing patterns include 4x4 (4 strands per inch in both directions), 3x3, 2x2, 4x2 and 3x2, which include It is not limited. Typical patterns are rectangles and rhombuses. The strand may be a material other than glass (eg, polyester) that provides the desired properties.

  Other reinforcements for the surface finish layers 22, 24 and / or 26 include, but are not limited to, glass mats, polymer mats and compounded mats. It is better to attach the reinforcing material to the metal foil in advance. As a modification, a reinforcing material placed in an unfastened state may be used. For many applications, the reinforcement consisting of the foil layer provides improved tear resistance, strength and / or soundproofing properties. However, it should be understood that for many applications, no reinforcement is required.

  The surface finish layers 22, 24 and / or 26 (whether reinforced or not) are attached to the polymer-based pad 12 by a heat activated adhesive. The adhesive utilized may be a thermoplastic sheet or thermoplastic web material that tends to melt and flow at temperatures of 200 ° F. to 300 ° F. (93.3 ° C. to 176.7 ° C.). This type of adhesive is desirable because it can be activated during the molding stage of manufacture. Besides thermoplastic sheets and webs, adhesives such as hot melts, latexes and various heat activated resins can be used. The adhesive may be a separate layer as shown, or the adhesive may be a surface finish layer 22, 24 and a dot matrix (ie, uniform) or sintered (ie, random) pattern. (Or) It may be already attached to 26.

  For example, a sound absorbing liner 10 with an integrated water barrier as shown in FIG. 5 is one possible product of the present invention. The sound absorbing liner 10 has a pad 12 made of fiber material. The pad 12 is made of a material that can absorb incoming sound waves and reflect the incoming sound waves to provide excellent silence. Thus, the pad 12 may be made of a material selected from the group consisting of polyester, polyethylene, polypropylene, polyethylene terephthalate, glass fiber, natural fiber, and any mixture thereof.

As shown in FIG. 6, the pad 12 has a bulky soundproof portion 14 having a density of about 8.0 to 80.0 kg / m ³ and a heat with increased density that resists water penetration and serves as a water barrier. A seal skin layer 16 is provided. The face 16 has a thickness of substantially 0.25 to 7.5 mm, and preferably has a density of about 32.0 to 1600.0 kg / m ³ .
The soundproof portion 14 and the skin layer 16 are integrally formed during the manufacturing process, and therefore the liner 10 is a non-laminated product. Because the liner 10 does not have layers bonded together by an adhesive, the liner does not tend to delaminate, thus providing reliable water barrier protection and soundproofing properties over a long useful life.

  A crimped edge 30 is provided around at least a portion of the outer periphery of the pad 12. The thickness of the crimped edge 30 is preferably about 0.5 to 3.0 mm. The material of the crimped edge portion 30 is compressed so as to have a feature of relatively high density. Thus, the crimped edge 30 is strong and thus a mechanical fastener (not shown) of the type known in the art that is used to secure the soundproof sheet material to a vehicle panel or the like, such as a screw. And suitable for holding plastic snap rivets.

  As shown, the liner 10 may further include various notch openings 32, 34 provided in the body thereof for receiving door operating structural members such as door latch handles and window operating mechanisms. A crimped edge 36 similar to the crimped edge 30 is preferably provided around one or more of these openings, such that the crimped edges are positioned around the opening 34. It is shown in FIG.

  In the modified embodiment of the liner 10 shown in FIG. 7, the second heat seal skin layer 18 is provided on the opposite side of the first heat seal skin layer 16. Although not explicitly shown, the edges of the liner 10 may also be heat sealed to promote water barrier protection in applications where water barrier protection is critical.

  The structure of the vehicle door 38 is shown in FIG. The door 38 includes an outer main body panel 40 including a window opening 42 and an inner fascia panel (partition plate) 44 as main components. A cavity 46 is formed between the two panels 40 and 44 when they are secured together. A liner 10 having a bulky soundproof portion 14 and at least one heat-sealed water barrier skin layer 16, as described above and shown in detail in FIG. 5, 6 or 7, is disposed in the cavity 46. . Specifically, the liner 10 can be secured to the outer panel 40 or inner panel 46 of the door 38 by mechanical fasteners or other means of the type known in the art.

  The insulator-type liner 10 of the present invention can be manufactured using a wide variety of techniques. The insulator type liner 10 can be prepared by differential heating and a uniform compression method. As a specific example, to prepare the liner 10 shown in FIG. 6, one side of a soundproof blanket or pad 12, ie, the side with a heat-sealed water barrier skin layer 16, is heated. Ensure that the other side remains relatively cool. Next, pressure is applied for a time sufficient for the polymer-bonded fibers to soften near the hot surface rather than near the cold surface. When this occurs under compression, the hot side is reshaped into a relatively dense layer or skin layer. The cold side of the polymer-bonded fiber does not soften, so when the pressure is removed, this cold side retains most of its original thickness and density characteristics. This technique can be implemented with a standard mold press where one surface plate operates at a high temperature and the other operates at a low temperature.

  Alternatively, two types of polymer-bonded fibers that have significantly different softening points are used. In one method, two separate blanket layers are made, each utilizing different melting polymer fibers. The two layers are bonded together in a molding operation using a differential heating method and compressed to a given gap width for a given period and given temperature difference. A blanket layer containing a polymer-bonded fiber having a low melting point is placed near the high temperature platen, and a blanket layer having a high softening point is placed near the low temperature platen. When compression occurs, the dense layer or skin layer 16 is made from a blanket layer with a low softening point, while the hot layer is unaffected and retains its original density. Also, the layers are fused to form an integral structure.

  In another method, a blanket layer containing a high melting point polymer fiber is preformed and then this layer is fed back through a forming oven during the molding of the low melting point blanket. Since the oven is operating at a temperature lower than that required to activate the high softening point polymer-bonded fibers, the polymer-bonded fibers are subjected to a compression action in the oven, but when they exit the oven Retain the original thickness and density. The material with a low softening point is also subjected to compression and since the oven is at a temperature sufficient to activate the polymer bonded fiber, the polymer bonded fiber is squeezed into a dense layer, The two layers are merged into one. Additional information regarding the manufacture of the insulator liner of the present invention can be obtained by reviewing co-pending US patent application Ser. No. 09 / 607,478, filed Jun. 30, 2000, such US patent application. The entire disclosure of the specification is hereby incorporated by reference as forming part of this specification.

  The foregoing description of the preferred embodiment of the present invention has been given for purposes of illustration and description. The present invention is not limited to the disclosed form itself. Modifications or variations apparent to those skilled in the art in light of the above teachings are possible. For example, the insulator-type liner 10 may have two skin layers that are both coated with a surface finish layer.
