【摘要】 采用2步法合成了原子灰用双环戊二烯(DCPD)型不饱和聚酯树脂,研究了原料用量对树脂性能影响,当n(顺酐)∶n(工业DCPD)∶n(精制DCPD)∶n(二元醇)=2.0∶0.7∶0.5∶1.75时,树脂性能稳定,原子灰综合性能如气干性、耐热性、打磨性、刮涂性、柔韧性等良好。更多还原

【Abstract】 Dicyclopentadiene(DCPD)type unsaturated polyester resin(UPR)for polyputty was prepared by two step method.The amount of every kind of material which would affect on resin and polyputty′s property was studied.When n(maleic anhydride)∶n(industrial DCPD)∶n(refined DCPD)∶n(di-alcohols)=2.0∶0.7∶0.5∶1.75,the properties of UPR were stable.The polyputty′s general properties,such as air-drying,heat resistance,grindability,knife coating property,toughness were excellent.更多还原
