(産業上の利用分野)
本発明は自動車用ハンドル等の部品、家具、鞄等の皮革
粉と熱可塑性樹脂とからなる皮革様成形品に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a leather-like molded article made of leather powder and a thermoplastic resin for parts such as automobile steering wheels, furniture, bags, etc.
(従来技術)
従来前記のような自動車部品や家具等において皮革状の
外観としたものは合成樹脂等の成形品、スチール、アル
ミ等の成形品に張着したもの或は木材等の表面に皮革を
張着したもので構成されたものが多かった。(Prior art) Conventionally, the above-mentioned automobile parts, furniture, etc. with a leather-like appearance have been made of molded products such as synthetic resin, molded products of steel, aluminum, etc., or pasted onto molded products such as wood, etc., or leather on the surface of wood, etc. Many of them were made up of things pasted together.
しかし、1−記のように皮革を張着したものは皮革が高
価であり、又張着のf間がかかるためコスト高となり、
又、寒暖による皮革と下生地との伸縮率が異るためズし
て生地の端部が露出したり、皮革が剥離して見苦しくな
る等の問題点があった。However, products with leather attached as described in 1-1 are expensive because the leather is expensive and it takes a long time to attach them, so the cost is high.
Furthermore, due to the difference in expansion and contraction rates between the leather and the underlying fabric due to temperature, there have been problems such as the edges of the fabric being exposed due to shrinkage, and the leather peeling off resulting in an unsightly appearance.
そこでこの問題点を解決するために皮革粉等を合成樹脂
に混入した皮革様の樹脂成形品としたものがあった。In order to solve this problem, there have been products made of leather-like resin molded products made by mixing leather powder or the like into synthetic resin.

製品が得られない等の問題点があった。(Problems to be Solved by the Invention) However, the above-mentioned leather-like sheets are made of leather powder in the form of fibers or lumps with cilia, which are relatively coarse powders, and do not mix uniformly with the thermoplastic resin. It is difficult to mix, and even during molding, the thermoplastic resin and the leather powder have different contact resistances with the die liner, cavity, mold, etc. of the injection molding machine, so they cannot be extruded smoothly and the parts of the molding machine described above On the other hand, there were problems such as a wave peg phenomenon occurring on the surface of the product, and changes in the injection pressure causing the flesh structure of the product to become dense and dense, making it impossible to obtain a homogeneous product.

成形品が得られるものである。(Function) According to the present invention, the leather powder 2 is dried to form finer particles of 50 to 250 mesh than conventional ones, and since the leather powder 2 consists of proteins, fats and oils, it has good lubricity and is a thermoplastic resin compound. The thermoplastic resin compound is dissolved in a solvent and the resin liquid is mixed with leather powder 2.
Even when mixed with leather powder 2, the resin liquid is not absorbed by the leather powder 2, so it mixes well and becomes homogeneous.In addition, the contact resistance with the inner surface of the mold, the liner of the die of the molding machine, the cavity, the surface of the mold, etc. Since the plastic resin compound and leather powder 2 are similar, injection molding can be performed smoothly during molding, and a homogeneous and high-quality leather-like molded product can be obtained without damage to the machine base or mold due to changes in injection pressure. It is something.

Alternatively, a thermoplastic resin compound is prepared by mixing a dried leather powder 2 containing 50 to 250 mesh of leather vinegar and a thermoplastic resin 3 such as vinyl chloride with a plasticizer, a stabilizer, a filler, an additive, etc. are uniformly mixed and molded, such as in powder form or dissolved in a volatile solvent to form a resin liquid, and the surface 1a is formed by the heat formed during molding + the amount of plastic resin 3. This is a skin layer 3a. Incidentally, the grained surface of the surface 1a is formed by a leather grain pattern provided in a mold during molding, and a wood grain pattern may also be provided on the mold surface to form a single shape on the wood.
