Abstract

The invention is applicable to the technical field of engineering plastics and provides a PP (polypropylene) / ABS (acrylonitrile-butadiene-styrene copolymer) alloy material as well as a preparation method and an application thereof. The PP / ABS alloy material comprises ABS and PP. The PP / ABS alloy material has the characteristics that the uniform dispersion of a fire retardant in the alloy material can be achieved through an ABS master batch containing the fire retardant so that the flame retardant property of the alloy material is improved greatly; and through the cooperative use of PP and ABS, the prepared alloy material has excellent mechanical properties, rigidity, creep resistance and dimension performance.

Description

technical field [0001] The invention belongs to the technical field of organic materials, and in particular relates to a PP / ABS alloy material, its preparation method and application. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer (ABS) is a general-purpose thermoplastic polymer with good rigidity, high impact strength, heat resistance, low temperature resistance, chemical resistance, mechanical strength and electrical properties. Processing, processing, good dimensional stability and surface gloss, easy to paint. Polypropylene (PP) is a crystalline non-polar high polymer with low price, non-toxicity, good fluidity, easy processing, fatigue bending resistance, chemical resistance and electrical insulation performance, but it has poor rigidity, large molding shrinkage, Dimensional instability, poor low-temperature impact performance and other deficiencies. The ABS / PP alloy material combines the advantages of both, but the existing ABS / PP alloy mater...
