发明内容
本发明的目的是提供一种以水性聚氨酯为载体的倒顺毛羊巴树脂,以水性聚氨酯为载体,减少溶剂型树脂易燃性、毒副作用和毒性,提高运输安全性。
本发明所述的一种以水性聚氨酯为载体的倒顺毛羊巴树脂,按重量,包括100-120份聚四氢呋喃二醇、25-35份聚氧化丙烯三醇、45-60份聚氧化丙烯二醇,0-10份精制蓖麻油,70-98份甲苯二异氰酯、20-30份3,5-二氨基-2,4,6-三甲基苯磺酸、10-24份三羟甲基丙烷、40-50份N-甲基吡咯烷酮、8-20份三乙胺、1-5份乙二胺、600-900份水、80-160份倒顺毛羊巴粉。
聚四氢呋喃二醇的平均重量分子量为2000。
聚氧化丙烯三醇的平均重量分子量为3000。
聚氧化丙烯二醇平均重量分子量为2000。
一种以水性聚氨酯为载体的倒顺毛羊巴树脂的制备方法,先将聚四氢呋喃二醇、聚氧化丙烯三醇和聚氧化丙烯二醇加入带搅拌器的反应器中于120℃真空脱水1小时,然后加入甲苯二异氰酸酯,于85℃~90℃反应1.5小时,加入3,5-二氨基-2,4,6-三甲基苯磺酸和三羟甲基丙烷,继续反应2小时,加入N-甲基吡咯烷酮,然后降至室温,加入三乙胺和乙二胺,加水乳化后、加入倒顺毛羊巴粉,搅拌分散2小时即得。
本发明技术方案实现的有益效果:
本发明公开了一种以水性聚氨酯为载体的疯马羊巴树脂,以水性聚氨酯为载体,降低了树脂的易燃性、毒副作用和毒性,提高运输安全性。将本发明树脂制成的合成革倒顺毛绒感特性。
