Abstract

The invention discloses a high strengthening and toughening type polyphenylene sulfide composite material. 100 wt% of the composite material comprises 45-55 wt% of polyphenylene sulfide resin, 30-50 wt% of glass fibers, 4-8 wt% of a toughening agent, 0.4-1.0 wt% of a compatibilizer and 0.1-3 wt% of other additives; the surface of the glass fibers is impregnated with a silane coupling agent; the toughening agent is at least one selected from nylon 6, nylon 66, ethylene-methyl acrylate-glycidyl methacrylate and a maleic anhydride grafted styrene-ethylene-butadiene-styrene block copolymer elastomer; and the compatibilizer is selected from epoxy resins. The polyphenylene sulfide composite material disclosed in the invention has the advantage of high rigidity, high toughness and high flame retardation property, is especially suitable for producing small parts and ultrathin parts which have high requirements for the impact performance, and greatly broadens the application range of a phenyl sulfide material.

Description

technical field [0001] The invention relates to the technical field of polyphenylene sulfide, in particular to a highly reinforced and toughened polyphenylene sulfide composite material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide (PPS) is the full name of polyphenylene sulfide, which is a thermoplastic resin with phenylthio group in the molecular main chain, and is currently the most engineered high-temperature-resistant plastic. Polyphenylene sulfide is a crystalline polymer, crystallization exotherm occurs at 125°C, glass transition temperature is 150°C; melting point is 280-290°C, continuous use temperature is 200-240°C, and decomposition temperature is 400°C. With the continuous improvement of high-temperature and high-strength requirements for plastics in various application fields, its development is very rapid, and it has been widely used in environmental protection, automobiles, electronics, petrochemicals, pharmaceuticals an...
