Preparation process of impact-resistant flame-retardant material applied to automobile instrument panel

Abstract

The invention discloses a preparation process of an impact-resistant flame-retardant material applied to an automobile instrument panel. The preparation process comprises the following steps: a, weighing raw materials in parts by weight for later use; b, drying and smashing all the materials weighed in the step a by category and in batches; c, obtaining an alloy solution; d, obtaining a mixture A;e, adding the mixture A into the alloy solution obtained in the step b, heating and uniformly stirring, and keeping a molten state at a constant temperature to obtain a mixed solution B; and f, performing pouring and molding to obtain a primary product, and the like. The preparation process is simple and scientific, the prepared impact-resistant flame-retardant material is high in overall performance, excellent in flame retardance and high in impact resistance, flames can be extinguished more quickly through performance tests, the combustion distance is shortened, the use requirement of an automobile instrument panel is met, and meanwhile, the impact-resistant flame-retardant material has good acid and alkali resistance, corrosion resistance, oxidation resistance, oil resistance, water resistance and the like.

Description

technical field [0001] The invention relates to the technical field of flame retardant materials, in particular to a preparation process of an impact-resistant flame retardant material applied to automobile dashboards. 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 indicator light, the ch...
