阅读说明：本技术 一种有机硅-氟改性单组份聚氨酯防水涂料及其制备方法 (Organic silicon-fluorine modified single-component polyurethane waterproof coating and preparation method thereof ) 是由 亓帅 张小冬 孙德文 沈志明 卢立群 冉千平 刘加平 刘畅 李波 朱剑南 王中华 于 2020-12-31 设计创作，主要内容包括：本发明公开了一种有机硅-氟改性单组份聚氨酯防水涂料及其制备方法。本发明所述聚氨酯防水涂料包括以下组分：异氰酸酯、端羟基聚醚二元醇、端羟基聚醚三元醇、有机硅烷封端剂、氟碳醇、增塑剂、溶剂、颜填料、催化剂及分散剂。本发明中所述有机硅-氟改性单组份聚氨酯防水涂料采用特定的有机硅、有机氟改性材料,对聚氨酯涂料改性,达到增强增韧目的；且有效地解决了有机硅-氟与传统聚氨酯树脂不相容的难题,该聚氨酯树脂含有有机硅烷和氟碳支链,能够使该聚氨酯树脂与建筑基材表面的羟基进行反应,从而具有很好的附着力,同时氟碳支链能够使该聚氨酯树脂具有疏水疏油的效果,耐候性大大提升。(The invention discloses an organosilicon-fluorine modified single-component polyurethane waterproof coating and a preparation method thereof. The polyurethane waterproof coating comprises the following components: isocyanate, hydroxyl-terminated polyether diol, hydroxyl-terminated polyether triol, an organosilane end-capping reagent, fluorocarbon alcohol, a plasticizer, a solvent, a pigment filler, a catalyst and a dispersing agent. The organic silicon-fluorine modified single-component polyurethane waterproof coating adopts specific organic silicon and organic fluorine modified materials to modify the polyurethane coating so as to achieve the purposes of strengthening and toughening; the polyurethane resin contains organic silane and fluorocarbon branched chain, and can react with hydroxyl on the surface of a building substrate, so that the polyurethane resin has good adhesive force, and meanwhile, the fluorocarbon branched chain can enable the polyurethane resin to have hydrophobic and oleophobic effects, and the weather resistance is greatly improved.)
