Low-smoke halogen-free flame-retardant material for automobile instrument panel and preparation method thereof

Abstract

The invention discloses a low-smoke halogen-free flame-retardant material for an automobile instrument panel and a preparation method of the low-smoke halogen-free flame-retardant material. The material comprises 140 parts by weight of acrylonitrile / polyethylene / propylene / vinyl acetate copolymer, 95 parts by weight of polyvinyl chloride, 48 parts by weight of silicone rubber, 12 parts by weight ofmethyltriethoxysilane, 8-12 parts by weight of magnesium hydroxide, 4-8 parts by weight of glass fiber, 2-6 parts by weight of chlorinated paraffin, 3-7 parts by weight of a modifier, 1-5 parts by weight of titanate, 3-7 parts by weight of nano cerium oxide, 2-6 parts by weight of a nano mesoporous molecular sieve and the like. The components are reasonable and scientific in preparation, the high-temperature-resistant and flame-retardant performance of the automobile instrument panel is effectively improved, the acid, alkali, corrosion, oxidation, oil, water and other performance of the instrument panel are improved, and the preparation process is simple and scientific, high in operability, low in manufacturing cost, wide in applicability, safe, reliable and the like.

Description

technical field [0001] The invention relates to the technical field of flame-retardant materials, in particular to a low-smoke, halogen-free flame-retardant material for an automobile instrument panel and a preparation method thereof. Background technique [0002] The car dashboard is a device that reflects the working conditions of the various systems of the vehicle. The common ones are fuel indicator light, washer fluid indicator light, electronic throttle indicator light, front and rear fog light indicator lights and warning lights. Different cars have different gauges. However, the conventional instruments of a general car include a speedometer, a tachometer, an oil pressure gauge, a water temperature gauge, a fuel gauge, a charging gauge, and the like. [0003] A variety of indicator lights or warning lights are made under the mask of the dashboard of a modern car, such as the coolant level warning light, the fuel level indicator light, the washer liquid level indicat...

Problems solved by technology

[0005] The flame retardant problem of existing automobile dashboards has gradually attracted the attention of countries all over the world; the release of a large amount of smoke and toxic and corrosive gases during combustion is a risk factor in fires, which hinders people's safe evacuation and fire fighting work during fires, making Life and property have suffered serious losses. At the same time, with the development of the automobile industry, it is increasingly necessary to use flame-retardant materials with low-flame retardant, low-smoke, good thermal stability, and high thermal deformation temperature.
