Abstract
The invention relates to a natural fiber composite material and a preparation method of the composite material. The composite material comprises the following components in parts by weight: 100 parts of thermoplastic resin, 5-50 parts of natural fiber, 0-20 parts of impact modifier, 0-30 parts of inorganic filler, 0.1-5 parts of anti-aging agent, and 0-10 parts of processing aid. The preparation method of the composite material comprises the steps of adding the natural fiber into an aqueous solution of a saline coupling agent to soak, then drying the natural fiber, mixing the natural fiber with the other processing aids, feeding the mixed material into a double-screw extruder to subject to the melting extrusion, and granulating to obtain the composite material. Compared with the prior art, the preparation method is simple in process and environment-friendly. More importantly, the problems that the composite material, into which a large amount of natural fiber is added, is poor in material mobility, low in intensity of parts, and poor in appearance quality, are solved. The current situation that the natural fiber composite material cannot adapt to the injection moldings of complex structures is changed.
Description
technical field [0001] The invention relates to a natural fiber composite material and a preparation method thereof. Background technique [0002] Natural fibers are the main load-bearing components of composite materials, which can not only increase the strength and modulus of materials, but also reduce shrinkage, increase heat distortion temperature and impact strength, etc. Compared with synthetic fibers, natural fibers have the advantages of low price, low density, and easy degradation. With the enhancement of people's awareness of environmental protection, natural fiber, as a "green material", has been paid more and more attention by people, and its application range has been continuously expanded. As a resin-based composite material reinforcement, the development speed is very rapid. Especially the application of natural fiber composites in automobiles is driving the growth of the market. Several automotive components are manufactured using natural fiber composites, ...
