Automobile sun visor composite materialand preparation method thereof

Abstract

The invention discloses an automobile sun visor composite material. The material is prepared from, by weight, 35-40 parts of polyurethane, 20-25 parts of polyphenyl thioether, 14-16 parts of boron fiber, 18-20 parts of kevlar, 6-11 parts of silicon carbide fiber, 7-12 parts of polyester resin, 8-10 parts of phenolic resin, 13-15 parts of polysulfide rubber, 8-14 parts of epoxy group, 2-6 parts of acrylate, 5-8 parts of ethylene-vinyl acetate copolymer, 10-16 parts of xanthate, 8-10 parts of phthalate and 2-9 parts of Ethylene-vinyl acetate copolymer, 6-7 parts of sorbitan monopalmitate, 12-16 parts of azimino-benzene, 17-22 parts of lauric acid and 4-9 parts of iron oxide red. The automobile sun visor composite material has the advantages of being good in anti-aging effect, long in service life, high in heat-resistant temperature and high in tensile strength.

Description

technical field [0001] The invention relates to a composite material of an automobile sun visor and a preparation method thereof. Background technique [0002] Existing sun visors are on the front windshield and rear windshield of the car. They are designed to avoid glare from the sun and can be moved back and forth, thereby adjusting the irradiance of the sun to the eyes and avoiding traffic accidents. The sun visor also makes it difficult for sunlight to enter the car directly, which has a better cooling effect, and can also protect the instrument panel and leather seats. There is also a sun visor with suction cups that attach to the side windows. With the continuous improvement of customers' requirements for sun visors, materials: plastic, EPP, PU foam, cardboard, etc., multi-functional sun visors, some with lights, some with mirrors. Traditional sun visors can no longer meet the needs of customers. Although traditional car sun visors can block sunlight, they occupy mo...

Problems solved by technology

A. Ordinary gauze-type side sunshade: This kind of sunshade usually has two suction cups, or one suction cup in the middle. The suction cup will be knocked off, especially the side sunshade with only two suction cups, it is easy to fall off

[0003] At present, the existing car sun visors have poor anti-aging effect, short service life, low heat resistance temperature and low tensile strength.
