Abstract

The invention relates to an anti-bacterial and high-flame-retardant ABS (acrylonitrile butadiene styrene) composite material and a preparation method thereof. The anti-bacterial and high-flame-retardant ABS composite material is prepared from following raw materials in parts by weight by processing: 60-80 parts of ABS resin, 40-60 parts of PC resin, 5-10 parts of EPDM resin, 6-10 parts of an antioxidant, 5-8 parts of nano-silver and 8-12 parts of a compound flame retardant, wherein a preparation method of the compound flame retardant comprises the following steps: strong phosphoric acid with the concentration of 85% is poured into a reactor, heated and stirred, a proper amount of urea is added when the temperature is increased to 60-80 DEG C, proper amounts of diatomite and magnetic ordered mesoporous nickel ferrite powder are added when the temperature is increased to 120-125 DEG C, the mixture is stirred for a reaction for 10-20 min, a product is cured at 280-320 DEG C for 1-2 h and ground by a nano-grinder, and the compound flame retardant is obtained. The ammonium polyphosphate-diatomite / magnetic ordered mesoporous nickel ferrite compound flame retardant is prepared from phosphoric acid and urea as main raw materials as well as diatomite and magnetic ordered mesoporous nickel ferrite as carriers through in-situ polymerization, and a synergistic flame retardant effect of ammonium polyphosphate with silicon, iron and nickel can be exerted sufficiently, so that the ABS composite material has good flame retardant performance.

Description

technical field [0001] The invention relates to an antibacterial and highly 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 us...
