聚氨酯树脂预聚体溶液及其制备的人造革雾洗亮涂饰剂
摘要：
本发明公开了一种聚氨酯树脂预聚体溶液，由下列质量份的原料经聚合反应制得：5~10的羟基封端的氟聚硅氧烷，20~30的甲苯二异氰酸酯（TDI），20~30的聚酯多元醇，1~5的乙二醇（EG），20~30的二甲基甲酰胺（DMF），20~25的甲苯，3~5的丙酮，1~2的有机锡催化剂。本发明同时公开了用上述的聚氨酯树脂预聚体溶液制备的人造革雾洗亮涂饰剂，由下列质量份的原料制得：20~60氟聚硅氧烷改性的聚氨酯树脂预聚体溶液，2~10的聚四氟乙烯蜡粉，2~10的沉淀法或气相法白炭黑，10~30的二甲基甲酰胺，20~30的甲苯。
摘要（英）：

The invention discloses a polyurethane resin prepolymer solution which is prepared from the following raw materials in parts by weight: 5-10 parts of hydroxyl-terminated fluoropolysiloxane, 20-30 parts of toluene diisocynate (TDI), 20-30 parts of polyester polyol, 1-5 parts of ethylene glycol (EG), 20-30 parts of dimethylformamide (DMF), 20-25 parts of toluene, 3-5 parts of acetone and 1-2 parts of organic tin catalyst. The invention also discloses an artificial leather fog washing bright finishing agent prepared by using the polyurethane resin prepolymer solution. The finishing agent is prepared from the following raw materials in parts by weight: 20-60 parts of the fluoropolysiloxane modified polyurethane resin prepolymer solution, 2-10 parts of Teflon wax powder, 2-10 parts of precipitated silica or fumed silica, 10-30 parts of dimethylformamide and 20-30 parts of toluene.
