Embodiment Construction

[0014] A composite material for anti-ultraviolet aging for automotive interiors, prepared from the following raw materials in parts by weight (kg): polylactic acid 100, nanometer antimony trioxide 3.5, decabromodiphenylethane 10, SEBS25, kenaf fiber 60. Cerium oxide 4, nano zinc oxide 7, benzotriazole 0.8, silane coupling agent KH5700.6, monoglyceride stearate 1, gelatin 5, appropriate amount of water, ammonium polyphosphate 1, EVA emulsion 6.

[0015] Described a kind of anti-ultraviolet aging composite material for automotive interior is made by the following specific steps:

[0016] (1) Dry the polylactic acid in a vacuum drying oven at 80°C for 10 hours, and dry the nano antimony trioxide and decabromodiphenylethane in an oven at 60°C for 5 hours and 8 hours respectively; the dried Put the material into a high-speed mixer, stir at a speed of 1000 rpm for 10 minutes, add SEBS, continue to stir for 10 minutes, and then send the mixture into a twin-screw extruder at a tempera...

Abstract

The invention discloses an ultraviolet and aging resisting composite material for an automotive upholstery. The ultraviolet and aging resisting composite material is prepared from by weight, 100-103 parts of polylactic acid, 3.5-4 parts of nanometer antimonous oxide, 10-11 parts of decabromodiphenyl ethane, 25-27 parts of SEBS, 60-62 parts of hibiscus cannabinus fibers, 4-5 parts of cerium oxide, 7-8 parts of nano-zinc oxide, 0.8-1 part of benzotriazole, 0.6-0.7 part of silane coupling agent KH570, 1-1.3 parts of stearoyl-rac-glycerol, 5-6 parts of gelatin, a proper amount of water, 1-1.4 pars of ammonium polyphosphate and 6-7.4 parts of EVA emulsion. According to the ultraviolet and aging resisting composite material, the mixed fibers are steeped into a modified mixture of the cerium oxide, the nano-zinc oxide and the benzotriazole which are in synergistic effect and cover the surfaces and pores of the mixed fibers, and the ultraviolet resisting effect of the mixed fibers is improved; meanwhile, the lubricating ingredients such as the stearoyl-rac-glycerol are contained in the material, so that the a subsequent extrusion granulating process is smoother, and processability is improved.

Description

technical field [0001] The invention relates to the technical field of automobile interior materials, in particular to an ultraviolet aging-resistant composite material for automobile interior decoration 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 important role in the ...
