摘要
以间苯二甲酸为饱和酸,工业双环戊二烯(DCPD)为改性剂,采用水解加成法合成了耐热原子灰用气干性不饱和聚酯树脂。研究了原料及用量对不饱和聚酯树脂和原子灰性能的影响,确定了不饱和聚酯树脂配方。当n(DCPD)∶n(间苯二甲酸)∶n(己二酸)∶n(剩余顺酐)=4∶4∶2∶9时,树脂性能稳定。以此树脂为基材,制得的原子灰耐热温度≥180℃,原子灰综合性能如刮涂性、气干性、打磨性和柔韧性良好。
The title air dry unsaturated polyester resins for heat resistant putty was prepared using hydrolysis addition process with isophthalic acid as saturated acid and dieyclopentadiene（DCPD） as modifier. The effect variety and amount of each material on properties of resin and putty was studied. The recipe of unsatu- rated polyester was determined. When n（DCPD） ： n（isophthalic acid） ： n（adipic acid） ： n（balance maleic anhydride） =4： 4： 2： 9, the properties of unsaturated polyester resin were stable. A heat resistance of the putty based on this resin was over 180℃. The comprehensive properties such as scraping property, air drying, grindability and flexibility were excellent.
