Abstract

The invention relates to ultraviolet-aging-resistant polyphenylene sulfide fibers and a preparation method thereof. The polyphenylene sulfide fibers comprise the following components in parts by weight: 100 parts of polyphenylene sulfide, 0.2-5 parts of 2-(3-N,N-diethyl-phenyl)amino-4,6-bis(4-tert-butyl-2-hydroxyphenyl)-sym-triazine and 0.2-5 parts of 2-ethylene imine-4-(2,2-dimethyl-4-tert-butyl)phenyl-6-(4-tert-butyl-2-hydroxy)-phenyl-triazine; and the fineness of the fibers is 1.2-6.6 dtex. The preparation method provided by the invention comprises the following steps of: adding polyphenylene sulfide, 2-(3-N,N-diethyl-phenyl)amino-4,6-bis(4-tert-butyl-2-hydroxyphenyl)-sym-triazine and 2-ethylene imine-4-(2,2-dimethyl-4-tert-butyl)phenyl-6-(4-tert-butyl-2-hydroxy)-phenyl-triazine to a screw spinning machine according to the proportions, carrying out melt spinning to obtain crude polyphenylene sulfide fibers, and then drawing and treating to obtain the fibers. The obtained fibers have greatly improved strength and modulus and excellent ultraviolet aging resistance.

Description

technical field [0001] The invention relates to an anti-ultraviolet aging polyphenylene sulfide (PPS) fiber and a preparation method thereof, specifically adding 2-(4-N,N-diethylaminophenyl)amino-4,6 bis(4 -tert-butyl-2-hydroxyphenyl)-triazine and 2-aziridine-4-(2,6-dimethyl-4-tert-butyl)phenyl-6-(4-tert-butyl- An anti-ultraviolet aging polyphenylene sulfide (PPS) fiber of 2-hydroxy)phenyl-s-triazine and a preparation method thereof. Background technique [0002] The English name of polyphenylene sulfide Poly(phenylene sulfide) is referred to as PPS, and its chemical structure It is a thermoplastic crystalline resin with excellent comprehensive properties that was put on the market by the American Philips Petroleum Company in 1968 under the Ryton trademark and started industrial production in 1973. Its melting point is as high as 280-290°C and its decomposition temperature is greater than 400°C. The outstanding features of PPS engineering plastics are high temperature res...
