Embodiment Construction

[0015] A composite automotive interior material capable of releasing negative ions, prepared from the following raw materials in parts by weight (kg): polylactic acid 100, nano antimony trioxide 3.5, decabromodiphenylethane 10, SEBS25, kenaf fiber 60. Tourmaline powder 15, medical stone powder 4.5, sodium polyacrylate 2, 3-aminopropyltriethoxysilane 0.6, white oil 2, seaweed gel 5, polytetramethylene glycol 3, water as appropriate.

[0016] Described a kind of composite automobile trim material that can release negative ions is made by following specific steps:

[0017] (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 stirring for 10 minutes, and then send the mixture into a twin-screw extruder at a temperature of 175 ° C...

Abstract

The invention discloses a composite automotive upholstery material capable of releasing negative ions. The composite automotive upholstery 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, 15-17 parts of tourmaline flour, 4.5-5.5 parts of medical stone powder, 2-3 parts of sodium polyacrylate, 0.6-0.7 part of 3-aminopropyltriethoxysilane, 2-2.5 parts of white oil, 5-6 parts of seaweed gel, 3-4 parts of polytetramethylene glycol and a proper amount of water. According to the composite automotive upholstery material, the technology that mixed fibers are steeped with modified tourmaline paste is adopted, so that an automotive upholstery made of the mixed material can generate high-concentration negative ions under the friction action of flowing air and external force, harmful gas in a carriage can be effectively decomposed, peculiar smells and smoke smells in air are eliminated, bacteria can be inhibited and killed, the amount of the bacteria in the upholstery is reduced, and the air quality in the carriage is effectively improved.

Description

technical field [0001] The invention relates to the technical field of automobile interior materials, in particular to a composite automobile interior material capable of releasing negative ions 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 comfort o...
