Abstract

The invention discloses graphene modified ABS resin and a preparation method thereof. The preparation method comprises the steps of providing melamine and diphenyl phosphoryl chloride, mixing the melamine and diphenyl phosphoryl chloride, and performing a combination reaction to obtain a melamine-diphenyl phosphoryl chloride compound; providing graphene oxide, mixing the melamine-diphenyl phosphoryl chloride compound and the graphene oxide, an performing a grafting reaction to obtain melamine-diphenyl phosphoryl chloride-graphene oxide; providing an ABS matrix, performing melt blending on themelamine-diphenyl phosphoryl chloride-graphene oxide and the ABS matrix, and obtaining graphene modified ABS resin. The problem that in the prior art, ABS resin is poor in flame retardant property issolved.

Description

technical field [0001] The invention relates to the technical field of ABS resin materials, in particular to a graphene-modified ABS resin and a preparation method thereof. Background technique [0002] ABS resin is composed of acrylonitrile-butadiene-styrene terpolymer, usually light yellow or milky white granular non-crystalline resin, is one of the five synthetic resins, its impact resistance, chemical stability, low temperature resistance Excellent chemical resistance, chemical resistance and electrical properties, and also has the characteristics of easy processing, stable product size and good surface gloss. It is widely used in industrial fields such as automobiles, machinery, electronic appliances, instrumentation, textiles and construction. One of the most widely used engineering plastics. However, its thermal stability is poor, it is easy to burn, and its mechanical properties need to be improved. [0003] Graphene oxide, as a new type of two-dimensional carbon m...
