Polyphenylene sulfide composite material and preparation method thereof

The invention relates to a polyphenylene sulfide composite material. The material comprises, by weight, 50-150 parts of polyphenylene sulfide resin and 1-20 parts of modifier. The general structural formula of the modifier is described in the description, wherein n ranges from 1 to 10, R1 is selected from H and at least one of hydroxyl-substituted C1-C4 alkyl groups or alkoxy groups, R2 is selected from H and at lest one hydroxyl-substituted C3-C10 naphthenic groups, and R3 is selected from H and at least one hydroxyl-substituted C6-C20 aryl groups or aryloxy groups. According to the polyphenylene sulfide composite material, on the one hand, the modifier has a large number of non-polar and polar functional groups, so that compatibility between the modifier and other components is good, accordingly it is ensured the components are not likely to be separated out in the processing process, and the flowability of the material is improved; on the other hand, at the processing temperature, the modifier permeates be
