聚氨酯玻璃及其制备方法
技术领域
本发明属于聚氨酯制品技术领域,具体涉及一种聚氨酯玻璃及其制备方法。
背景技术
玻璃是一种较为透明的固体物质,在熔融时形成连续网络结构,冷却过程中粘度逐渐增大并硬化而不结晶的硅酸盐类非金属材料,普通玻璃的主要成分是二氧化硅,广泛应用于建筑物。普通玻璃进行深加工处理后可得到钢化玻璃、夹层玻璃等种类。而这些玻璃的保温性能、隔热性能、强度等和聚氨酯玻璃有很大的差距。
发明内容
本发明的目的是提供一种聚氨酯玻璃,具有良好的保温性能、隔热、机械强度高、有一定的弹性、抗冲击性、碎后不易伤人,耐光性、耐环境性能优的优点;本发明同时提供了聚氨酯玻璃的制备方法,科学合理、简单易行。
本发明所述的聚氨酯玻璃由如下重量份数的原料制成:
所述的聚醚多元醇DDL-1000D为2官能度,分子量1000的聚醚多元醇;该聚醚由淄博德信联邦化学工业有限公司生产,用这类多元醇做的制品强度高。
所述的聚醚多元醇DDL-2000D为3官能度,分子量2000的聚醚多元醇;该聚醚由淄博德信联邦化学工业有限公司生产,用这类多元醇做的制品抗撕裂。
所述的HMDI(4,4'-二环己基二异氰酸酯)的加入使得制品耐光性、耐候性、制品机械强度高。
所述的固化剂为1,4-丁二醇,与预聚体中的NCO基团反应,固化成形。
本发明所述的聚氨酯玻璃的制备方法,步骤如下:
(1)聚醚多元醇DDL-1000D和聚醚多元醇DDL-2000D在100-120℃抽真空脱水1.5-2.0h,降温45-55℃后加入HMDI,70-80℃合成预聚体;
(2)将预聚体和固化剂混合,混合温度为75-85℃,混合均匀后倒入模具中硫化30min后脱模,在100-110℃下硫化8-12h后得到产品。
步骤(1)中所述的预聚体的NCO含量为3-9%。
本发明与现有技术相比,具有如下有益效果:
(1)具有良好的保温性能、隔热、机械强度高、有一定的弹性、抗冲击性、碎后不易伤人,耐光性、耐环境性能优等优点。
(2)本发明制备方法简单易实施。
