Problems solved by technology

For example, Chinese patent application No. 201010269051.6 discloses a composite material formed of natural fiber and synthetic resin or polylactic acid, in which resin is added and contains harmful substances such as formaldehyde or melamine. Although the cost is low, the environmental protection is poor and the material elasticity is low. Poor, the flame retardant performance can not reach UL94-V0
Chinese patent application No. 201210219204.5 discloses a natural fiber / polylactic acid composite material and its preparation method. The composite material is mainly used in plastic products industries such as films, profiles, sheets and containers. Poor performance, not suitable for use in the field of automotive interior materials

Abstract

The invention relates to a degradable vehicle interior decoration composite material and a processing process thereof, and provides a degradable vehicle interior decoration composite material having characteristics of high strength, beautiful outlook and low cost and meeting vehicle interior decoration member base requirements, and a processing process thereof, wherein the degradable vehicle interior decoration composite material comprises, by mass, 35-45% of polylactic acid fibers and 55-65% of natural fibers, wherein the natural fibers are fibrilia, the fibrilia is one or compounding of more than any two selected from hemp fibers, jute fibers, flax fibers and/or sisal fibers, the natural fibers further comprise bamboo fibers, a ratio of the fibrilia to the bamboo fibers is 1:0.1-0.5, and the diameter of the bamboo fibers is 0.1-0.9 mm. According to the present invention, the degradable vehicle interior decoration composite material has advantages of green environmental protection raw materials, light weight, no toxicity, no odor, complete biodegradation and recycling, and the mechanical property, the thermal stability, the combustion characteristics, the organic matter volatility, the odor and other indicators of the product completely meet the technical requirements of the vehicle interior decoration material.

Description

technical field [0001] The invention relates to the technical field of composite molding materials, in particular to a degradable automotive interior composite material used for automotive interior parts and a processing technology thereof. Background technique [0002] With the rapid development of the automobile industry today, artificial synthetic fiber materials still play an important role in automobile interiors, mostly derived from petroleum-derived polymer materials. Due to the non-renewability of energy and the increasingly prominent environmental problems, biodegradable materials It has become a development trend for materials to replace traditional petroleum products. Since the European Union and German legislation stipulated the proportion of degradable materials used in automotive interiors in 2006, natural fibers have been used as reinforcements due to their high specific strength, high specific modulus, low price, degradable, renewable, and green environmental...
