Description
【発明の詳細な説明】 本発明は熱賦形性の良い成形材）トに関する。[Detailed description of the invention] The present invention relates to a molding material with good heat formability.
従来、繊維状物が熱可塑性樹脂によって結着された成形
材料は種々のものが使用されているが、耐熱性と熱賦形
性の両者がすぐれたものはない。即ち耐熱性がすぐれた
もの＃ｉ熱賦形性が悪く、熱賦形性がすぐれたものは耐
熱性が悪いという欠点を有していた。Conventionally, various molding materials in which fibrous materials are bound by thermoplastic resins have been used, but none have excellent heat resistance and heat formability. That is, those with excellent heat resistance #i had poor heat shaping properties, and those with excellent heat shaping properties had the disadvantage of poor heat resistance.
本発明は上記欠点に鑑み耐熱性と熱賦形性の両者がすぐ

る結着剤により結着されてなる成形材料に存する。In view of the above-mentioned drawbacks, the present invention has been made for the purpose of providing a molding material that is excellent in both heat resistance and heat formability. It consists in a molding material that is bound together by a binder made of two or more types of thermoplastic resins that are not compatible with each other.

ましい。Fibrous materials used in zero-start LJI include, for example, inorganic fibers such as glass fiber, rock cool, asbestos, and ceramic 7-iper, and synthetic resins such as polyamide, polyethylene terephthalate, polyacrylonitrile, polyvinylidene chloride, and polyvinyl alcohol acecooled product. textile manufacturing,
Examples include cotton, hemp, silk, pulp, raw wool, wool, pig hair, horse hair, etc., and vegetable fibers such as cotton, hemp, and rope are suitably used for rounding to reduce the weight of the molding material. Particularly preferred is lupus. When using the above-mentioned vegetable fibers, the higher the content of the fibers in the molding material, the lower the heat formability, and the lower the content, the lower the thermal dimensional stability. It is preferable that it be contained in the molding material in an amount of 90 to 50% by weight since it may impair properties.

３：１であるのが好ましい。In the present invention, the fibrous material is bound by a binder made of a thermoplastic resin, but the binder is made of two or more thermoplastic resins that have different glass transition temperatures and are not compatible with each other. It is preferable to use a mixture of thermoplastic resins with glass transition temperatures of 100°C or higher and 50°C or lower; The ratio with things is 1
If the ratio Σ of 00°C or higher increases too much, the thermal formability deteriorates, and conversely, if it decreases, the heat resistance decreases, so 1:1 ~
Preferably, the ratio is 3:1.

燥する方法が好ましい。Any method may be used to produce the molding material of the present invention; for example, emulsions of two types of thermoplastic resins that have different glass transition temperatures and are not compatible with each other are mixed, impregnated into a fibrous material, and dried. Here are some ways to do it. In addition, to produce a lightweight molding material, the emulsion and wL fiber material are mixed and foamed, the fibrous material and thermoplastic resin float together with the foam to form a scum, and the scum is scooped out and dried. A method of doing so is preferred.

がすぐれている。As mentioned above, the composition of the molding material of the present invention is that the fibrous material is bound by a binder made of two or more types of thermoplastic resins that have different glass transition temperatures and are not compatible with each other.
By applying pressure at a relatively low temperature, thermal shaping can be easily performed, and the molding material does not buckle at this time. It also has excellent heat resistance, as it will not undergo thermal deformation as long as it is pressurized even at high temperatures.
従って本発明の成形材料Ｖ１自動車の内装材、折版屋根
