Anti-aging and high flame retardant ABS composite material and preparation method thereof

Abstract

The invention relates to an anti-aging and high flame retardant ABS composite material and a preparation method thereof. The anti-aging and high flame retardant ABS composite material is prepared from 80 to 100 parts by weight of ABS resin, 40 to 60 parts by weight of PC resin, 5 to 15 parts by weight of EPDM resin, 6 to 10 parts by weight of an antioxidant and 8 to 12 parts by weight of a compound flame retardant. The preparation method comprises pouring concentrated phosphoric acid having a concentration of 85% into a reactor, carrying out heating stirring, adding an appropriate amount of urea into the mixture when the temperature rises to 60 to 80 DEG C, adding an appropriate amount of diatomite and magnetic ordered mesoporous nickel ferrite powder when the temperature rises to 120 to 125 DEG C, carrying out a stirring reaction process for 10 to 20min, curing the product at a temperature of 280 to 320 DEG C for 1 to 2h, and crushing the product through a nano-crusher to obtain the anti-aging and high flame retardant ABS composite material. The preparation method utilizes phosphoric acid and urea as main raw materials, diatomite and magnetic ordered mesoporous nickel ferrite as carriers and an in-situ polymerization method to prepare the ammonium polyphosphate-diatomite / magnetic ordered mesoporous nickel ferrite composite flame retardant and can give full play to synergistic flame retardant effects of ammonium polyphosphate and silicon, iron and nickel so that the ABS composite material has good flame retardant properties.

Description

technical field [0001] The invention relates to an anti-aging high flame-retardant ABS composite material and a preparation method thereof. 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 aut...

AI Technical Summary

Problems solved by technology

ABS resin can be used in the interior and exterior of the car, small parts such as steering wheel, oil guide pipe, handle and button, etc. The exterior of the car includes front radiator grille and lampshade, etc. The current ABS resin has poor flame retardancy and anti-aging performance. The present invention aims to solve this technical problem
