High-strength and anti-static polyphenylene sulfide and preparation method thereof

Abstract

The invention relates to high-strength and anti-static polyphenylene sulfide and a preparation method thereof, belongs to the technical field of composites, solves the technical problem that static isproduced easily by polyphenylene sulfide in the prior art, and further improves strength of polyphenylene sulfide. High-strength and anti-static polyphenylene sulfide is prepared from 100 parts by weight of polyphenylene sulfide, 10-12 parts by weight of polyoxymethylene, 3-5 parts by weight of polyaniline, 1.5-3 parts by weight of stannous sulfate, 2-3 parts by weight of hexadecyltrimethylammonium chloride, 2-4.5 parts by weight of polysiloxane, 2-2.5 parts by weight of cellulose fiber, 1-2 parts by weight of basalt fiber, 0.2-1 part by weight of an antioxidant, 3.5-6 parts by weight of silicone powder, 1-3 parts by weight of a coupling agent and 0.2-0.5 parts by weight of sodium benzoate. According to high-strength and anti-static polyphenylene sulfide, strength of polyphenylene sulfideis improved while anti-static performance of polyphenylene sulfide is improved.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a high-strength antistatic polyphenylene sulfide and a preparation method thereof. Background technique [0002] The full name of polyphenylene sulfide is polyphenylene sulfide, which is a thermoplastic resin with phenylthio groups in the main chain of the molecule. It has excellent high temperature resistance, corrosion resistance, radiation resistance, flame retardancy, balanced physical and mechanical properties, excellent dimensional stability and excellent electrical properties. The heat distortion temperature (1.8MPa, unannealed, 3.20mm) is 93.0°C , the tensile modulus is 2500MPa, the flexural modulus is 3300MPa, and the notched impact strength of the cantilever beam (23°C) is 29J / m. It has been successfully applied in the fields of electronic appliances, aerospace, automobile transportation and so on. [0003] However, due to the excellent insulat...

Problems solved by technology

[0003] However, due to the excellent insulating properties of polyphenylene sulfide, it is easy to generate static charge when rubbing in dry air. The accumulation of static electricity will cause electrostatic attraction (or repulsion), electric shock or spark discharge. The conditions are easy to cause huge disasters and seriously affect the service life of materials

In the prior art, conductive carbon black is often used to improve the antistatic property of polyphenylene sulfide, but carbon black is difficult to disperse, and the dosage is large. After adding, it is easy to affect the strength of polyphenylene sulfide
