Abstract

The invention relates to a highly flame-retardant ABS material for automobile interior parts and preparation method of material. The highly flame-retardant ABS material is prepared from, by weight, 80-120 parts of ABS resin and 8-12 parts of composite flame retardant. The composite flame retardant is prepared by the steps of adding 85% strong phosphoric acid into a reactor, heating and stirring, raising the solution temperature to 60-80 DEG C, adding suitable amount of urea, continuing heating until the temperature reaches 120-125 DEG C, adding suitable amount of diatomite and magnetic ordered mesoporous nickel ferrite powder, stirring for reaction for 10-20 minutes, curing the product under 280-320 DEG C for 1-2 hours, finally pulverizing with nano pulverizer to acquire the composite flame retardant. The phosphoric acid and urea are used as the main materials, the diatomite and magnetic ordered mesoporous nickel ferrite powder are used as the carriers, and through the method of in-situ polymerization, the ammonium polyphosphate-diatomite / magnetic ordered mesoporous nickel ferrite composite flame retardant is prepared. The synergistic flame retardant functions between the ammonium polyphosphate and the elements of silicon, iron and nickel are fully exerted to make the ABS material possess prominent flame retardant performance.

Description

technical field [0001] The invention relates to a preparation method of a high flame-retardant ABS material used for automotive interior parts. Background technique [0002] ABS resin (acrylonitrile-styrene-butadiene copolymer) is a thermoplastic polymer material structure with high strength, good toughness and easy processing. [0003] ABS is a general-purpose thermoplastic engineering plastic developed in the 1940s. It is a plastic variety with excellent comprehensive mechanical properties. It not only has good rigidity, hardness and processing fluidity, but also has high toughness. It can be injected, extruded or heated. forming. [0004] Most of the auto parts are processed by injection molding method, the advantages of ABS resin are impact resistance, sound insulation, scratch resistance, better heat resistance, more beautiful than PP, especially suitable for transverse impact resistance and use Temperature-critical parts. ABS resin is the third largest resin used in...
