Abstract

The invention discloses a bamboo-powder-added enhanced composite automotive interior product material. The material is prepared from, by weight, 100-103 parts of polylactic acid, 3.5-4 parts of nanometer antimony trioxide, 10-11 parts of decabromodiphenyl ethane, 25-27 parts of SEBS, 60-62 parts of kenaf fibers, 10.5-12 parts of bamboo powder, 5-6.5 parts of carboxymethyl cellulose, 4.5-5.5 parts of talcum powder, 8-9 parts of ethyl alcohol, 0.8-1 part of silane coupling agent kh550, 1-2 parts of stearic acid, 3-4 parts of polyacrylamide and a proper amount of water. The silane coupling agent is used for treating the bamboo powder, the talcum powder and other components to form soaking slurry, environment friendliness is achieved, the tenacity and strength of fibers are enhanced, the bonding performance and description performance of the bamboo powder and other components and the blend fibers can be improved, the processing technology is conveniently and industrially controlled, the following extrusion technology is good in liquidity, the prepared product is good in appearance and free of warping, good bending strength is achieved, and environment friendliness is achieved.

Description

technical field [0001] The invention relates to the technical field of automobile interior decoration materials, in particular to a reinforced composite automobile interior decoration material added with bamboo powder and a preparation method thereof. Background technique [0002] The interior parts of a car generally refer to parts and materials such as partitions, door trim panels, instrument panel assemblies, armrests, and carpets in the car compartment. Compared with other parts on the car, they have little effect on the running performance of the car, but their face can be seen at a glance, representing the image of the whole car, which one is better, determines the reputation and grade of the car, and determines the choice of people. car intent. In addition, for cars, although the interior parts are only some auxiliary parts, they have to undertake functions such as vibration reduction, heat insulation, sound absorption and sound insulation, which play a very importan...
