POLYVINYL ALCOHOL FIBER REINFORCED POLYPHENYLENE SULFIDE COMPOSITE AND PREPARATION METHOD THEREFOR

摘要

Disclosed is a polyvinyl alcohol fiber reinforced polyphenylene sulfide composite, comprising polyphenylene sulfide, polyvinyl alcohol fiber, glass fiber, and an additives. The additive comprises a compatilizer, an antioxidant, a coupler, and a lubricant. Also disclosed is a preparation method for a polyvinyl alcohol fiber reinforced polyphenylene sulfide composite, comprising the following steps: (1) mixing and dispersing polyphenylene sulfide, polyvinyl alcohol fiber, and glass fiber, and a compatilizer, an antioxidant, a coupler, and a lubricant to obtain a mixture; and (2) feeding the mixture into an extruder to extrude a strip-shaped composite, and then obtaining colloidal particles through granulation by using a granulator. The polyvinyl alcohol fiber reinforced polyphenylene sulfide composite provided in the present invention has the advantages of high strength, low creep deformation, good liquidity, being easy to process, high toughness, and high modulus.
