Abstract

The invention belongs to the technical field of high polymer materials and discloses a glass fiber reinforced impact-resistant polyphenylene sulfide composite and a preparation method thereof. The composite is composed of, by weight, 50-70 parts of polyphenylene sulfide, 30-50 parts of glass fibers, 1-4 parts of flexibilizer, 0.4-0.6 part of antioxidant and 0.5-1 part of processing aid. The preparation method of the composite includes the steps: firstly, adding the 50-70 parts of polyphenylene sulfide, 1-4 parts of flexibilizer, 0.4-0.6 part of antioxidant and 0.5-1 part of processing aid into a mixer and mixing for 30min; and secondly, adding the mixture obtained at the step one into an extruding machine through a hopper, adding the 30-50 parts of glass fibers through a glass fiber port, and performing melt extrusion and granulating. The glass fiber reinforced impact-resistant polyphenylene sulfide composite has excellent impact resistance and high mechanical strength.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a glass fiber reinforced impact-resistant polyphenylene sulfide composite material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide (PPS) is a high-temperature-resistant thermoplastic engineering plastic with good comprehensive properties first developed by the Phillips Petroleum Company of the United States in the 1960s. The melting point of polyphenylene sulfide is about 286°C, the glass transition temperature is 110°C, the degree of crystallinity is 55-65%, and the starting temperature of decomposition in air is as high as 450°C, which has excellent properties. After modification, the short-term thermal deformation temperature of PPS resin is as high as 260°C, and the long-term continuous use temperature is 200-240°C. It is one of the resins with the highest thermal stability in thermoplastics; PPS is insoluble in any ...
