Abstract

The invention relates to an environment-friendly vehicle natural fiber composite material and a preparation method as well as application thereof. The preparation method of the vehicle natural fiber composite material comprises the following steps of: treating a continuous natural fiber fabric with water content of less than 0.2 percent by using a silane coupling agent; immersing the treated continuous natural fiber fabric in mixed slurry; drying the immersed continuous natural fiber fabric until the water content is less than 0.2 percent; soaking in molten polylactic acid with density of 1.22 g / cm<3>; performing hot pressing on the soaked fabric at 170-190 DEG C to obtain a natural fiber polylactic acid composite felt; and slicing the natural fiber polylactic acid composite felt, laminating and performing hot forming at 170-190 DEG C to obtain the vehicle natural fiber composite material. According to the vehicle natural fiber composite material, the natural fiber and the polylactic acid are used as raw materials, and the raw materials have environment-friendly sources, are renewable and can be completely degraded.

Description

technical field [0001] The invention relates to a natural fiber composite material for vehicles and its preparation method and application, in particular to a natural fiber composite material for vehicles with green raw material source, renewable and completely degradable, its preparation method and application. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, the fiber materials used in automobile interior decoration will develop from economical and practical to functional, fashionable, lightweight and green. The chemical fibers commonly used in automobile decoration materials are as follows. 1. Functional fibers Automotive decorative textiles have high requirements for new functional fiber raw materials, and their processing and finishing processes are also very complicated. In addition to meeting the general requirements of textiles, these textiles also have special requirements for materials s...
