补充资料:不饱和聚酯
| 不饱和聚酯 unsaturated polyesterresins 由二元醇与全部或部分不饱和二元酸缩合聚合所得的树脂。英文缩写 UP。由于主链含-CH=CH-双键结构,能与烯类单体如苯乙烯、丙烯酸、乙酸乙烯酯等进一步聚酯的性能随原料不同而有很大变化,通常有较好耐热性、绝缘性、耐水和耐化学、耐老化,增强后的树脂则有很高的机械性质。典型的不饱和聚酯制备是将1,2 -丙二醇,顺丁烯二酸酐、邻苯二甲酸酐混合后,在氮或二氧化碳气氛中150~200℃缩合十几小时,直到生成低酸值线性树脂,分子量1000~2500,再加入苯乙烯等单体稀释。使用时加入过氧化物引发剂,在100℃进行热交联,或添加促进剂( 为钴盐)后在室温下交联成固体,此外也可用紫外线、γ射线、电子束等辐照交联。空气中的氧对树脂之交联有阻聚作用,在线性聚酯链中引入烯丙基醚、苄基醚等“气干性”基因可赋予常温自干性;引入环烷烃二元醇等可获得高软化点树脂。不饱和聚酯主要用于涂料和高级油漆、装饰铸塑件 、电器铸件、腻子和胶泥。用玻璃纤维、碳纤维等增强制造玻璃钢,用于造船、建筑材料、车辆、化工设备、运动器材等。加入光敏固化剂后还可制造印刷工业用的感光树脂版。 |
