Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to the surface of an engine cover or other automobile parts as a vibration damping and soundproofing material, or
The present invention relates to an elastic material that is attached to the inner surface of a room as a sound absorbing material, or is attached to the back surface of a building material as a vibration isolator, or is attached to a floor surface and is used as a cushion material.

[0002]

2. Description of the Related Art In order to obtain a building material having sound insulation and soundproofing, a foam having a hollow portion is attached to the back surface of a wooden floor building material (Jikkou 4-43543 / Kaikai Sho 62-20123).
9) Alternatively, a cork having a foamed structure is attached (Jpn. 4-43542, Jpn. Pat. Appl. 62-194031), a method of laminating foam between the front and back materials (Jpn.
-12202 / Shokaisho 62-32139) is adopted. In order to suppress vibration generated from an automobile engine or a floor surface, a method of backing and laminating an adhesive resin composition such as rubber asphalt or acrylic resin on the back surface of a metal plate or other plate material is adopted (Act No. 4 7949 / Shokai 62-53137, Japanese Examined Patent Publication 4-153 / JP 62-3746
1). In order to add elasticity to the floor of the stadium or gym,
A method of laminating a mixed composition of a binder and rubber granules on a floor substrate has been adopted (Japanese Patent Publication No. 4-66977, JP-A-60-144458). Also, in order to prevent the impact sound on the floor from being transmitted to the downstairs, it is said that a woven fabric or knitted fabric composed of thick fiber threads like wire is laminated on the floor slab ( Actual fairness 4-45876, actual Kaihei 1-177729). In addition, generally, rubber asphalt and other adhesive resin compositions are effective in absorbing and damping vibrations, and a fiber aggregate and cork, rubber foam, which are made into a felt shape by compressing or needle punching the fiber web. Resin foams such as polyurethane foam and polyvinyl chloride foam are effective for soundproofing, sound absorption and vibration damping, and are used as cushioning materials and the like.

[0003]

A vibration-damping / vibrating material made of a rubber asphalt or other adhesive resin composition that absorbs and attenuates vibrations, and most of the adhesive resin composition is softened by heat and becomes fluid. Since it is easy to use, it is difficult to use in the vicinity of vibration sources that generate heat, such as around the automobile engine.
Further, the resin foam is configured as an aggregate of fine resin coatings surrounding the bubbles, and external forces such as tear tension, tensile tension, and compression load applied to the resin foam are finely divided and distributed around the bubbles. It acts on the resin film. In this way, the external force applied to the resin foam does not always apply evenly to the entire resin foam, and it does not always divide finely and evenly to act on the resin film around the bubbles. It rarely acts uniformly on the whole or around the resin film around each bubble, and in many cases, it partially acts on it. In particular, the tearing tension often acts in a biased manner on the resin film around the bubbles in a part of the resin foam, and at that time, the thickness of the resin film around the bubbles is not constant and has a large variation. External force acts on the thin fragile part,
The destruction starts from a part of it and extends to the entire resin foam. Therefore, even if the resin itself constituting the resin foam has excellent physical properties, the resin foam is not always strong in strength. Since the thin resin film around the bubbles is easily attacked by the rays, gas, solvent, etc., to the inside of the resin film, the elastic material of the resin foam has a problem in terms of service life.

[0004] In addition to spandex fibers, the fiber assembly has elasticity of ordinary fibers such as wool, nylon, polyester fibers and rayon as compared with elastic resins such as vinyl chloride resin, natural rubber and synthetic rubber. In addition, since ordinary fibers do not have an adhesive property, they do not have a function of absorbing vibration, and therefore cannot be attached to an engine cover and used as a damping material. And, even if the fiber has a higher physical strength than the solidified product of the fluid resin composition which is the raw material of the resin foam, the fiber aggregate is a fiber in which fibers are accumulated and entangled with each other. Since the fibers of (3) are easily separated, they are unstable in strength as compared with the resin foam. Of course, it is conceivable to impregnate a felt, which is commonly used as an elastic material, with a fluid resin composition as a raw material for a resin foam and bond the fibers to stabilize the strength. However, the fibers forming the felt are made of felt. Of the resin composition that can be applied in the relationship of adhesion with the fibers constituting the felt because it is deposited so as to extend in the felt length direction rather than in the thickness direction of the felt. There are restrictions on the types.

Therefore, the present invention combines a fiber excellent in strength and a resin excellent in elasticity to provide a vibration damping material, a soundproofing material,
An object of the present invention is to obtain an elastic material having excellent durability which can be used as a sound absorbing material, a cushioning material or the like.

Elastic material 17 according to the present invention
Is formed by impregnating the fluid pile resin composition 12 into the loop pile 16 of the loop pile material and integrating the fluid pile resin composition 12 with the loop pile layer 11 of the loop pile material, and having a loop pile structure inside. It is characterized by. Loop pile 1 wrapped in a fluid resin composition 12
6 should form a granular mass, and for that,
(A) The volume ratio of the loop pile fiber 13 to the resin composition 12 in the loop pile layer 11 is 1: 0.1 to 10, and (b) the inside of the loop pile 16 and the loop pile 1
Leaving voids 14 and 15 between 6 and 16 respectively,
(C) Loop pile layer 11 of those voids 14 and 15
It is advisable to set the volume ratio to 20% or more (less than 100%).

The elastic material 17 shown in the figure is constructed by using as a base material a loop pile fabric in which the pile yarn 19 is inserted into the base fabric 20 by a tufting machine to form the loop pile 16. A Wilton loom, a towel loom, a horizontal (circular) knitting machine, a warp knitting machine, and the like, on which the base cloth 20 and the loop pile 16 are simultaneously formed, can be used. The pile fabric normally formed by a tufted machine, a moquette loom, a Wilton loom, a towel loom, a horizontal (circular) knitting machine, a warp knitting machine, etc. is used as a moquette or carpet that touches the skin. Organic fibers such as wool, rayon, polyester fibers, nylon, acrylic fibers, etc., which are soft to the touch, are used, and inorganic fibers are not used. However, in the present invention, the elasticity generated due to the structure of the loop pile forming a loop shape is utilized, and it is used as a material of an elastic material which is wrapped and integrated with a resin composition. Therefore, it is possible to use inorganic fibers such as glass fiber, aramid fiber, carbon fiber, graphite fiber, metal fiber, etc., which are not conventionally used for pile yarn of pile fabric, and thick fiber having a poor touch.

As the fluid resin composition 12, various resins may be used as long as they are fluid and viscous so that they can penetrate between the fibers 13 of the loop pile 16. For example, a paste-like product obtained by swelling vinyl chloride or other resin powder with a plasticizer, a solvent solution-type product in which a resin is dissolved in an organic solvent, or an emulsion-type product in which latex or other swollen resin particles are dispersed in water. And the like are used, and they are prepared by appropriately mixing various auxiliaries such as a vulcanizing agent, a stabilizer, a crosslinking agent viscosity adjusting agent, and a pigment.

When the elastic material 17 is required to have a high sound insulation property, a filler having a high specific gravity such as slag, lead, iron oxide, barium sulfate or the like is mixed with the fluid resin composition 12, and the elastic material 17 is electrically conductive. When the elasticity is required, carbon black or other conductive fillers may be blended. When the elastic material 17 is required to have a vibration damping property, the resin composition 12 may be a rubber asphalt or an acrylic resin, Adhesive resins such as petroleum-based resins may be used.

The fluid resin composition 12 is added to the loop pile layer 1
In order to impregnate No. 1, the fluid resin composition 12 may be sprayed or coated on the surface of the loop pile layer 11, or the loop pile material may be dipped in the bath of the fluid resin composition 12. The volume ratio of the loop pile fiber 13 to the resin composition 12 in the loop pile layer 11 is determined by the surface portion of the loop pile layer 11, that is, the tip portion 2 of the loop pile.
1 and a deep portion of the loop pile layer, that is, a root portion 22 of the loop pile, and an intermediate portion 23 between the surface portion and the deep portion,
It may be changed for each part of the loop pile 16.

In the present invention, the first reason for applying the resin composition 12 to the loop pile 16 is to reinforce the loop pile 16 and increase the resilience. Loop pile 16
The second reason for applying the resin composition 12 to the resin composition 12 is that the resin composition 12 forms a coating film on the surface of the loop pile fiber 13, and the coating film is supported by the loop pile fiber 13 and This is to form a bulky porous elastic structure. The third reason for applying the resin composition 12 to the loop pile 16 is that the coating film of the resin composition 12 forming a bulky porous elastic structure such as foam is reinforced by the fibers 13 of the loop pile and is broken. This is because it becomes difficult to prevent intralayer delamination in the bulky porous elastic structure.
In that case, in order to ensure that the elasticity generated from the shape of the loop pile 16 in which the loop pile fibers 13 are in a loop shape is effectively generated even after the resin composition 12 is applied, the space between the loop piles 16 16 voids 15 are left, and voids 14 between the fibers 13 inside the loop pile 16 are left, so that the loop pile 16 having a loop-like shape is coated with the resin composition 12. It is good to leave it after you wear it. Fibers 13 that form a ring shape like that
In order for the elasticity generated from the structure of (1) to remain even after application of the resin composition 12, the loop pile fiber 13 has a fineness of 50 as in the case of a Tegus yarn having a thickness of 0.1 to 1.0 mm.
A thick monofilament with a denier or better should be used.

Voids 14.1 occupied in the loop pile layer 11
The volume ratio of 5 is the planting density of the loop pile 16 (intervals e and f in the vertical and horizontal directions), and the pile yarn 1 forming the loop pile 16
9 thickness, concentration of solid content in the fluid resin composition 12,
It can be adjusted depending on the amount of the fluid resin composition 12 applied, and for that purpose, it is effective to prepare the fluid resin composition 12 by passing it through a foaming machine and foaming. In particular, in order to increase the volume ratio to 80 to 99%, the loop pile 16 is partially planted in a pattern in the base cloth 20, and a wide space 18 is provided between the loop pile 16 and the loop pile 16. Even in such a case, the loop pile layer 11 as a porous structure in which the resin composition 12 is integrated with the fibers 13 of the loop pile may be formed. For that reason, and in order to effectively exert the elastic force of the structure of the loop pile 16, the volume ratio of the voids 14 inside the loop pile to the loop pile 16 is 1.
It should be 0 to 80%.

However, in particular, when the solidified resin composition 12 is a soft solid such as jelly or pudding or a soft and tacky solid, the fluid resin composition 12 is used as a loop pile material. In addition, a large amount can be applied and sufficiently impregnated without leaving voids 14 and 15 inside the loop pile 16 or between the loop piles 16 and 16.

The elastic material 17 according to the present invention can be used by adhering it to a tile carpet, a metal plate, or the back surface of the wooden building material 25, and has a space inside the loop pile 16 or between the loop piles 16 and 16. In the case where the loop pile 16 is made into a granular mass while leaving 14 and 15, particularly, in the case where the wide space 18 is provided between the loop piles 16, the elastic material 17 is used as it is for the rug, the wall material and other interior materials. It can also be used as

[0015]

The elastic material 17 according to the present invention is composed of the loop pile 16 and the resin composition 12 which form a ring-shaped elastic structure, and the loop pile 16 is reinforced by the resin composition 12. The resin composition 12 is less likely to be plastically deformed, and the solidified resin composition 12 is reinforced by the loop pile 16 and is less likely to be broken.

Even when the amount of the resin composition 12 applied is small and there is a gap between the loop pile 16 and the loop pile 16, the resin composition 12 becomes a granular mass and protrudes onto the surface of the elastic material 17. , The loop pile fiber 13 is present in the granular mass, and the loop pile fiber 13 is used as the base fabric 20.
Since it digs deep inside, the granular mass does not fall off even if it is rubbed.

When the coating amount of the resin composition 12 is small,
The resin composition 12 forms a film that easily expands and contracts between the fibers 13 and has the voids 14 and 15 as cores inside the loop pile layer like a resin foam such as rubber foam or polyvinyl chloride foam. Since it forms a porous structure, strong elasticity is generated. Therefore, the elastic material 17 according to the present invention is
Compared with conventional elastic materials such as fiber aggregates and resin foams, and loop pile fabrics, they are superior in elasticity, physical properties and durability.

Even if the resin composition 12 has an adhesive property and the resin foam made of the resin composition 12 is crushed by the bubbles and easily adheres to be transformed into a non-foamed product, In the loop pile layer 11 at
Since 15 is supported by the loop pile 16, it is difficult to be crushed, and the porous structure of the elastic material 17 by the voids 14 and 15 is maintained.

Since the resin composition 12 is carried by the loop pile 16, the elastic material 17 is made of the highly adhesive resin composition 12 which becomes fluid when heated and is easily drooped.
Since the resin composition 12 having such a high adhesiveness exhibits a vibration damping effect of damping vibration,
It is possible to obtain the elastic material 17 that can be used as a vibration damping material or a sound absorbing material in the high temperature region around the engine cover and the like.

Since the loop pile fiber 13 projects from the base cloth 20 and extends in the thickness direction of the elastic material 17, the elastic material 1
Even if 7 is adhered to a wall foundation or floor foundation 24, no peeling occurs in the layers, and the elastic material 17 is attached to the back surface of the tile carpet, metal plate, wood building material 25, or the surface material 27 and the back surface material. It is possible to obtain a damping wall material having excellent durability, an interior material such as a damping floor material, a damping surface material for a building panel, a damping surface material for a vehicle body panel, etc.

The surface of the loop pile 16 is covered with the film 12 of the resin composition so that dust is not easily adsorbed inside, and the cleaning water used during cleaning can be easily shaken off so that cleaning is easy, and Further, as shown in FIG. 3, even if the granular projections in which the space 18 is large and the loop pile 16 and the resin composition 12 are integrated are projected sparsely, those projections are securely locked to the base cloth 20 by the fibers 13. The elastic material 17 can be used as it is as a mat, floor material, cushion material, interior material, etc. with the loop pile layer 11 facing the front side which is easily rubbed.
