摘要
本文以Sb2O3为催化剂,采用熔融法合成端羟基聚酯树脂,分别以10%、30%、50%的有机硅中间体进行化学改性,以偏苯三甲酸酐对有机硅改性后的聚酯进行了水性化封端,并采用二甲基乙醇胺成盐,制备的水性有机硅改性聚酯树脂配以氨基树脂固化成膜后,表现出具有优良耐高温性、高硬度、良好柔韧性等性能,实验表明,当有机硅含量为30%时,改性聚酯树脂树脂的综合性能和性价比最好。
In this paper,hydroxy polyester resins were synthesized through melting.In this process,antimonous oxide was used as catalyst and 10%,30% and 50% of organosilicon intermediate was used to chemical modification respectively.The modified organosilicon polyester resin with trimellitic anhydride was processed with water base-side processing,then salted with dimethylethanolamine.This kind of water-soluble organosilicon modified polyester resin treated with this way was used to cure and film with amino resin,which performs excellent high temperature resistant,high solidity and excellent flexibility.The experiment results showed that the compositive property and the price performance is the best when the content of organosilicon is 30%.
