Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated material for a vehicle seat for suppressing an electric shock due to static electricity when a person sitting on the vehicle seat touches a low-potential object, and a method of manufacturing the same.

[0002]

2. Description of the Related Art
In order to alleviate the discomfort (electric shock) caused by the generation of static electricity when getting off the vehicle, various antistatic treatments such as spraying of a surfactant for preventing static electricity have been taken.

At present, the most effective method is to coat the back surface of the sheet skin in which the conductive yarn is woven, with a conductive backing material, and then bond it to urethane foam as a seat pad with an adhesive or frame laminate ( This is a laminate material for a vehicle seat obtained by melting and laminating urethane foam with a flame. Here, the conductive backing material refers to a material in which a resin component such as an acrylic resin contains, in addition to a conductive material such as carbon, a flame retardant such as antimony trioxide for making the skin of the sheet difficult to burn.

However, since the resin component of the conductive backing material is used exclusively as a binder, it is contained only in a small amount, and there is a problem that a rough texture of carbon or a flame retardant appears on the sheet skin. In addition, since the number of steps for coating the sheet skin with the conductive backing material increases, there is a problem that the number of production steps increases and the cost increases.

On the other hand, as another conventional example, for example, Japanese Patent Application Laid-Open No. 63-194940 discloses that a cushioning material (seat pad) is impregnated with a conductive substance and adhered to a conductive skin material body. A skin material having an antistatic function is disclosed. However, in this case, the number of steps for impregnating the sheet pad with the conductive substance increases, so that there is a problem that the number of production steps increases and the manufacturing cost increases.

Japanese Unexamined Patent Publication (Kokai) No. 1-171936 discloses a napped fabric antistatic knitted fabric in which a conductive foam material (sheet pad) is adhered to a knitted fabric mixed with conductive fibers. However, in this case, as the seat pad, a foam made by mixing conductive particles such as carbon particles or metal particles based on a resin such as polyurethane or polyethylene is used, but the conductivity tends to be nonuniform, and the performance is high. There is a problem that is easy to vary.

The present invention has been made in view of the above problems, and provides a laminate material for a vehicle seat, which has a function of preventing electrostatic shock stably, can be manufactured at low cost, and has a soft feel, and a method for producing the same. With the goal.

[0008]

Means for Solving the Problems, Embodiments of the Invention and Effects of the Invention In order to solve the above-mentioned problems, a laminate material for a vehicle seat of the present invention provides a seat skin formed using conductive fibers and a cushioning property. And a conductive adhesive layer including a conductive filler and bonding the sheet skin and the sheet pad.

In such a laminate material for a vehicle seat, electric charges generated on the surface of the seat skin are collected in conductive fibers or conductive fillers in the conductive adhesive layer of the seat skin and dispersed over a wide range or by self-discharge. Static electricity is removed. For this reason, the effect of being able to suppress the sense of electric shock due to static electricity when a person sitting on the vehicle seat touches a low-potential object is obtained.

[0010] Japanese Patent Laid-Open Publication No.
In No. 6, since it is difficult to uniformly mix the conductive particles into the seat pad, the conductive particles are not sufficiently distributed on the skin side of the seat pad, and there is a possibility that the function of preventing a sense of electric shock cannot be stably obtained. However, in the present invention, since the conductive adhesive layer having the conductive filler is provided between the sheet skin and the seat pad, the function of preventing electric shock is stably obtained.

Further, conventionally, there has been a problem that the conductive backing material is coated on the back surface of the sheet skin, so that the conductive backing material deteriorates the texture. However, the present invention does not use the conductive backing material. And the effect of improving the feeling is obtained. Furthermore, since it is manufactured in a single step of bonding the sheet skin and the seat pad with a conductive adhesive, the production cost is higher than in the case of having multiple steps. Is low.

In the present invention, the conductive filler contained in the conductive adhesive includes powders such as metals and metal oxides such as silver, copper and iron, carbons such as carbon black and graphite, and fibrous materials. There are things. Among them, carbons are lower in adhesion performance of the adhesive than in the case of metals and metal oxides, a good conductive effect can be obtained with a small amount of addition, and low in specific gravity and excellent in dispersibility. preferable.

Examples of the adhesive for the conductive adhesive include oil-soluble materials such as hot melt, epoxy and urethane, copolymers such as vinyl acetate, acryl, ethylene and styrene and / or aqueous and chloroprene monomers and / or mixtures. There are solvent systems such as SBR, but these are not necessarily limited to oil-soluble, aqueous and solvent systems.
Solvents such as epoxy and urethane may be used.

The amount of the conductive filler is preferably 0.1 to 200 parts by weight based on 100 parts by weight of the solid content of the adhesive as a binder. If the amount is less than 0.1 part by weight, the conductive effect is almost completely lost, which is not preferable. If the amount exceeds 200 parts by weight, the adhesiveness is reduced, the cost is increased, and the hand tends to be hardened, which is not preferable. Further, it is more preferable to add 2 to 30 parts by weight. In this case, the effect of suppressing the electric shock feeling, the adhesiveness, and the feeling are extremely excellent.

As the conductive adhesive, if desired, tackifying resins such as rosin resin and petroleum resin, pigments such as titanium oxide and iron oxide, fillers such as calcium carbonate and clay, and zinc oxide and phenol derivatives. Antioxidants, surfactants such as polyoxyethylene derivatives and sodium lauryl sulfate may be added.

The seat skin is not particularly limited as long as it is formed using conductive fibers. For example, a woven fabric or a knitted fabric in which conductive yarn has been woven can be used as long as it is suitable as a skin of a vehicle seat. It is. The seat pad is not particularly limited as long as it has a cushioning property. For example, in addition to urethane foam which is a porous substance, other foam materials, felts, nonwoven fabrics and the like can be used.

In the laminate material for a vehicle seat of the present invention, the conductive adhesive layer is preferably 5 to 100 g / m ² in order to obtain good adhesiveness and conductivity. 5g / m
Not preferable because there is a tendency that the adhesion-conductive lower is less than ^2, is not preferable because there is a tendency that the texture exceeds 100 g / m ² becomes hard.

In the laminate material for a vehicle seat of the present invention, a part of the conductive adhesive layer may be present in a state of seeping into the seat skin and / or the seat pad. Since the sheet skin is formed using conductive fibers, the conductive adhesive usually penetrates easily, and when the sheet pad is made of, for example, a porous substance or a nonwoven fabric, the conductive adhesive similarly penetrates. As a result, a part of the conductive adhesive layer is present in a state of seeping into these. As described above, when a part of the conductive adhesive layer is present in a state of seeping into the sheet skin and / or the seat pad, when the amount of the conductive adhesive layer used is 5 to 100 g / m ² , The thickness of the adhesive layer is 5 to 1000 μm including the portion that has permeated into the sheet skin and / or the sheet pad.

In the vehicle seat laminate of the present invention, the conductive adhesive layer preferably contains a phosphorus-based flame retardant. In a laminate material containing a conductive filler (particularly carbon), when a flame retardant other than a phosphorus-based flame retardant (for example, a halogen-based flame retardant or an inorganic metal compound-based flame retardant) is used, the conductive filler becomes a candle core during the burning process. Thus, there is a problem that the so-called candle phenomenon in which the fire keeps burning cannot be suppressed, and the burning continues for a long time. On the other hand, the use of a phosphorus-based flame retardant is preferable because such a candle phenomenon can be suppressed and combustion can be stopped quickly. The flame retarding mechanism of the phosphorus-based flame retardant is generally described as follows. That is, when the phosphorus-based flame retardant is exposed to a fire, the phosphorus compound is sequentially decomposed in the order of a phosphorus compound → phosphoric acid → metaphosphoric acid → polymetaphosphoric acid, and the generated phosphoric acid layer forms a non-volatile protective film. The dehydration function advances the organic matter in the direction of carbonization, forms a carbonized film, physically shuts off the supply of oxygen, and provides a flame retardant effect.

As the phosphorus-based flame retardant, any of inorganic phosphorus-based flame retardants and organic phosphorus-based flame retardants can be used. The inorganic phosphorus-based flame retardant is, for example, phosphorus, phosphoric acid, orthophosphoric acid, or the like.
Examples include metaphosphoric acid, polyphosphoric acid, and salts thereof. As the organic phosphorus-based flame retardant, for example, phosphates,
Examples include phosphonates, phosphites, phosphorus-containing polyols, phosphonate-type polyols, and phosphate-type polyols. Among them, as the phosphates, non-halogen-containing compounds such as trimethyl phosphate, triethyl phosphate, tributyl phosphate, trioctyl phosphate, tributoxyethyl phosphate, triphenyl phosphate, tricresyl phosphate, cresyl diphenyl phosphate, octyl diphenyl phosphate, Tris (chloroethyl) phosphate, tris (2-chloropropyl) phosphate, tris (2,3-dichloropropyl) phosphate, tris (2,3-dibromopropyl) phosphate, tris (bromochloropropyl) phosphate,
Halogen-containing compounds such as bis (2,3-dibromopropyl) -2,3-dichloropropyl phosphate, bis (chloropropyl) monooctyl phosphate, polyphosphonate, polyphosphate, and aromatic polyphosphate. These phosphorus-based flame retardants may be used alone or in combination of two or more.

Of the phosphorus-based flame retardants, those containing halogen are not environmentally preferable because a gas containing hydrogen halide is released during combustion, and in view of this, a halogen-free phosphorus-based flame retardant is preferred. . Regarding the addition ratio of the phosphorus-based flame retardant, the solid content of the adhesive as a binder was 10%.
It is preferable to add 1 to 200 parts by weight of a phosphorus-based flame retardant to 0 parts by weight. If the amount is less than 1 part by weight, the flame-retardant effect cannot be sufficiently obtained, so that it is not preferable. If the amount exceeds 200 parts by weight, the adhesiveness is reduced, the cost is increased, and the texture is hardened. Further, it is more preferable to add 5 to 50 parts by weight, in this case, a flame retardant effect,
Excellent adhesion and texture.

The method of manufacturing a laminate material for a vehicle seat according to the present invention includes a step of bonding a seat skin formed using conductive fibers and a seat pad having a cushioning property with a conductive adhesive containing a conductive filler. Here, as a method of applying the adhesive, the adhesive may be applied to the entire surface to be applied (the back surface of the sheet skin or the surface of the sheet pad). This is preferable because the weight per unit area of the adhesive can be reduced and the texture of the obtained laminate can be softened.

In this manufacturing method, it is preferable that a conductive adhesive is applied to the sheet pad, and that the surface of the sheet is placed on the applied surface and bonded. Normally, the seat pad is thicker than the seat skin, so workability is good. Also, when the vehicle seat laminate has a laminated structure of the seat skin, adhesive layer, seat pad, adhesive layer, backing fabric, the front and back of the seat pad It is preferable to apply an adhesive to both surfaces so that the bonding process can be integrated into one.

In this production method, the conductive filler is carbon, and the conductive adhesive is 0.1 to 200 parts by weight based on 100 parts by weight of the solid content of the adhesive.
It is preferable to include the parts by weight and the amount of the conductive adhesive to be used is 5 to 100 g / m ² in terms of the solid content.

Further, in this manufacturing method, the conductive adhesive contains a phosphorus-based flame retardant.
It is preferable that the phosphorus-containing flame retardant is non-halogen-containing as the phosphorus-containing flame retardant.
