Problems solved by technology

[0003] At present, due to the moisture absorption of plastics, the rapid hydrolysis and aging of plastic parts cannot be used in the field of water-related products.
However, materials with low hygroscopicity such as PPO and PEEK still cannot meet the requirements of the wading industry due to many reasons such as high price and difficult processing. The plastics currently used in the wading industry are all vacuum-plated to slow down their hydrolysis aging. , the process is extremely complex

Abstract

The invention discloses a hydrolysis-resistant polyphenylene sulfide composite modified material and a preparation method thereof. The polyphenylene sulfide composite modified material is prepared from the following raw materials in percent by mass: 45%-72% of polyphenylene sulfide powder, 20%-46% of alkali-free glass fibers, 2.5%-5% of vinyl silicone oil, 0.5%-1% of a silane coupling agent, 1.0%-2% of a hydrolysis resistant agent, 0.3%-0.5% of an antioxidant and 0.5%-0.8% of a chemical assistant. The hydrolysis-resistant polyphenylene sulfide composite modified material prepared by the preparation method disclosed by the invention has the advantages of hydrolysis resistance, high and low-temperature resistance, acid / alkaline resistance and the like, and can be used for placing a copper material and a steel material in the wading industry, so that a purpose of lowering cost is reached; moreover, service life of products can be effectively prolonged, and phenomena such as difficult processing are improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a hydrolysis-resistant polyphenylene sulfide composite modified material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide resin (PPS), also known as polyphenylene sulfide, has good comprehensive properties, high temperature resistance, corrosion resistance, radiation resistance, non-flammability, and good mechanical and electrical properties, so polyphenylene sulfide is The material of choice in the fields of electronics and electrical appliances. [0003] At present, due to the moisture absorption of plastics, the rapid hydrolysis and aging of plastic parts cannot enter the field of water-related products. However, materials with low hygroscopicity such as PPO and PEEK still cannot meet the requirements of the wading industry due to many reasons such as high price and difficult processing. The plastics currently used in the wading ...
