NOVELTY - High-temperature resistant special polyester comprises 15-30 pts. wt. polyethylene terephthalate, 20-30 pts. wt. polyurethane prepolymer, 10-20 pts. wt. epoxy resin, 1-6 pts. wt. 4-7C polyfunctional compound, 30-50 pts. wt. flame retardant, 2-10 pts. wt. compatibilizer, 2-5 pts. wt. heat stabilizer, 1-3 pts. wt. antioxidant, 1-3 pts. wt. inorganic filler and 1-3 pts. wt. UV absorber. USE - As high-temperature resistant special polyester. ADVANTAGE - The high-temperature resistant special polyester has high temperature resistance, UV resistance, excellent wear resistance, dynamic performance and long service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the high-temperature-resistant special polyester, which involves (i) adding epoxy resin and 4-7C polyfunctional compound to polyurethane prepolymer for condensing and refluxing, and reacting under the protection of nitrogen at 60-90 degrees C for 0.5-1.5 hours to obtain a mixture (A), and (ii) adding polyethylene terephthalate, flame retardant, compatibilizer, heat stabilizer, antioxidant, inorganic filler and UV absorber to the mixture (A), and maintaining the reaction temperature at 85-95 degrees C for 2-2.5 hours.
