Abstract

The invention discloses an antioxidant toughening modified polyphenylene sulfide (PPS) monofilament and a preparation method of the PPS monofilament. The method of the invention comprises the steps of adding an antioxidant, a toughener, and a dispersing coupler into the polyphenylene sulfide powder to prepare antioxidant toughening modified polyphenylene sulfide chip, and melting and spinning; wherein the antioxidant toughening modified polyphenylene sulfide chip consists of the following components by weight: 95-97% of polyphenylene sulfide powder, 0.2-0.6% of antioxidant, 1-4% of inorganic toughener and 1-2% of dispersing coupler. According to the formula of the antioxidant toughening modified polyphenylene sulfide chip and the preparation method of the antioxidant toughening modified polyphenylene sulfide monofilament of the invention, modified polyphenylene sulfide monofilaments with superior breaking strength, breaking elongation, dry-heat shrinkage, antioxidant performance and toughness can be produced, and the method is stable in production process, low in cost, and good in product quality.

Description

technical field [0001] The invention relates to the field of special chemical fibers, in particular to an anti-oxidation toughening modified polyphenylene sulfide monofilament and a preparation method thereof. Background technique [0002] Polyphenylene sulfide (English name Polyphenylene Sulfide, abbreviated as PPS) fiber was first successfully developed by Philips Petroleum Company of the United States. The company started industrial production of PPS resin in 1973, developed fiber-grade PPS resin in 1979, and industrialized PPS short fiber in 1983. Due to the excellent performance of polyphenylene sulfide fiber, Japan's Toyobo, Toray, Teijin and German Bayer have also developed and produced polyphenylene sulfide fiber. [0003] Polyphenylene sulfide can be made into filaments and short fibers, and can also be made into monofilaments. Due to its good textile processing performance and excellent chemical resistance, thermal stability, high temperature resistance and flame...
