Abstract

The invention provides a raw bamboo fiber and polypropylene staple fiber composite molding interior panel and a preparation process thereof. The interior panel has a surface layer of a decorative fabric, a second layer of a hot melt adhesive film, a third layer of a first non-woven fabric, a fourth layer of a raw bamboo fiber and polypropylene staple fiber mixed needled felt and a fifth layer of a second non-woven fabric, wherein the raw bamboo fiber and polypropylene staple fiber mixed needled felt comprises the following components in percentage by weight: 53 to 56 percent of raw bamboo fiber and 44 to 47 percent of polypropylene staple fiber. The composite molding interior panel has excellent comprehensive performance and is high in environment friendliness.

Description

【Technical field】 [0001] The invention relates to an interior trim panel formed by composite molding of bamboo fiber and polypropylene short fiber applied to a base material of an interior trim panel of an automobile and a preparation process thereof. 【Background technique】 [0002] The major OEMs in the automotive industry are very concerned about the environmental protection of automotive interiors. The environmental protection of automotive interiors is mainly reflected in two aspects: one is that the formaldehyde content and total carbon volatilization of automotive interior materials are related to the health of passengers. Healthy technical indicators; the second is whether the automotive interior materials are recyclable and easy to degrade. According to the regulations of the European Community, by 2015, automobiles must be made of 95% recyclable materials, which also requires the development of natural fiber raw materials that are environmentally friendly and have t...
