Problems solved by technology

However, alkali-free glass fiber (E glass fiber, with aluminoborosilicate as the main component) is usually used to reinforce PPS. Due to its poor acid resistance, products requiring higher acid resistance, such as toilet water pipes and bathroom pipes Accessories, water heater accessories, etc., in a long-term acid environment (acid detergent, etc.), will cause problems such as reduced strength, impact resistance, pressure resistance, and heat resistance.

Abstract

The invention discloses glass flber reinforced polyphenyl sulfide resin compound. The comprised components and their mass proportion are as follows: (A) polyphenyl sulfide resin 60- 90; (B) medium alkali glass fibre 40 -10; (C) unsaturated carboxyl acid and ABS copolymer, 5- 15; (D) organosilicon polymer, 1- 5. The medium alkali glass fibre is surface treated with modified epoxy resin- containing wetting agent. The invention is to provide a kind of glass flber reinforced polyphenyl sulfide resin compound and the final product, which is characterized by excellent rigidity, anti-vibration, thermal tolerant and flame proof property, and good water- proof and acid- resistant performance.

Description

technical field [0001] The invention relates to the technical field of glass fiber-reinforced flame-retardant polymer materials, in particular to a glass fiber-reinforced flame-retardant polystyrene with excellent rigidity, impact resistance, heat resistance and flame retardancy, which is suitable for water-resistant and acid-resistant environments. Thioether resin composition. Background technique [0002] Polyphenylene sulfide (PPS) is a thermoplastic special engineering plastic with excellent comprehensive properties. Its outstanding features are high temperature resistance, corrosion resistance, radiation resistance, non-combustibility, rigidity and excellent electrical properties. The use of glass fiber reinforced PPS can greatly improve its properties such as tensile strength, flexural strength, flexural modulus, impact strength and heat distortion temperature. It is mainly used in automobile manufacturing, electronic appliances, machinery industry, chemical instrument...
