Abstract

The invention relates to an anti-ultraviolet polyphenyl thioether filament and a preparation method thereof. The polyphenyl thioether filament comprises, by mass fraction, 90 to 99.9 percent of polyphenyl thioether resin and 0.01 to 10 percent of photostabilizer. The preparation method comprises the following steps: (1) mixing titanate coupling agent with ethanol water, then adding nano TiO2 particles, and drying after constant temperature reflux; (2) the TiO2 particles treated by the titanate coupling agent, 2, 2'-methene di-(6-(2H-benzotriazole-2-yl)-4-(1, 1, 3, 3-tetramethyl butyl) phenyl hydroxide and polyphenyl thioether, and then kneading, uniformly mixing and drying to obtain dry powder; and (3) extruding and pelletizing the dry powder, drying to obtain dry anti-ultraviolet polyphenyl thioether chips, performing melt spinning, drawing and performing heat shaping to obtain the anti-ultraviolet polyphenyl thioether filament. The stability of the modified filament under ultraviolet light is remarkably improved, and the preparation method is simple to operate and low in cost.

Description

technical field [0001] The invention belongs to the field of nanometer functionally modified polyphenylene sulfide filament and its preparation, and in particular relates to an anti-ultraviolet polyphenylene sulfide filament and a preparation method thereof. Background technique [0002] Polyphenylene sulfide fiber is one of the newly developed high-performance fibers in recent years. With its excellent corrosion resistance and high temperature resistance, it has broad application prospects in military, electronic and electrical, and industrial fields. Polyphenylene sulfide filaments are mainly used in filter fabrics for industrial coal-fired boiler bag filter chambers. However, because industrial polyphenylene sulfide is used as a high-temperature dust filter bag, etc., it is in a light-proof environment, so the ultraviolet light stability of polyphenylene sulfide filaments has not been fully studied. There are few research literatures on the photostability of polyphenylen...
