Problems solved by technology
As far as the polyphenylene sulfide composite materials currently on the market are concerned, they can no longer meet the growing requirements for high performance. Therefore, it is still necessary to develop a composite material with high formability, high rigidity, high impact resistance, and lower cost. polyphenylene sulfide composite

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...
