Description

环保型聚氨酯防水涂料
技术领域
本发明涉及防水涂料的技术领域，特别涉及聚氨酯防水涂料的技术领域。
背景技术
传统的聚氨酯防水涂料多采用毒性大的甲苯二异氰酸酯TDI作为主要原材料，TDI对生产过程中的工艺控制要求较低且生产出的聚氨酯防水涂料各项性能较稳定，但是TDI自身存在很大的毒性，在生产过程中无法将自身的毒性反应掉，故生产出的聚氨酯防水涂料带有毒性。从防水涂料的发展趋势看，环保型的防水涂料越来越受青睐。鉴于TDI的较高毒性，可以用二苯基甲烷二异氰酸酯MDI替代毒性大的甲苯二异氰酸酯，采用基本无毒性的MDI制备预聚体，不添加再生橡胶和煤焦油，且不使用任何溶剂，有利于环境保护和工人健康。
目前市场上的聚氨酯防水涂料分为单双组分，双组分的工艺控制难度较低，故少数厂家用二苯基甲烷二异氰酸酯MDI替代了甲苯二异氰酸酯TDI生产出环保型双组份聚氨酯防水涂料。由于单组份聚氨酯防水涂料对工艺、配方难度要求特别高，且MDI用作生产聚氨酯防水涂料时，对工艺、配方比TDI要求更高，故市场几乎没有MDI型单组分环保聚氨酯防水涂料。双组分的聚氨酯防水涂料在施工现场需将A组分和B组分混合，对现场施工时的技术要求高，施工不简便，但单组分可在现场直接开桶施工，因此，单组分比双组分具有更大的优势。
发明内容
