Polyurethane self-adhesive film waterproof roll as well as preparation method and application thereof
The invention discloses a polyurethane self-adhesive film waterproof roll as well as a preparation method and application thereof. The polyurethane self-adhesive film waterproof roll sequentially comprises an epoxy modified polyurethane film, a self-adhesive layer and a protective liner from top to bottom, the preparation method of the epoxy modified polyurethane film comprises the following steps: dispersing 10-15 parts by mass of a reactive flame retardant in 20-30 parts by mass of tetrahydrofuran, uniformly mixing with 40-60 parts by mass of a polyurethane prepolymer, 15-20 parts by mass of epoxy acrylate and 5-10 parts by mass of fluorinated epoxy resin, heating to 50-55 DEG C, carrying out pre-reaction for 0.5-1 hour, heating to 70-80 DEG C, adding 1-2 parts by mass of bis (dimethylaminoethyl) ether, carrying out heat preservation and stirring reaction for 3-6 hours, and cooling to room temperature to obtain the epoxy modified polyurethane film. Pouring the mixture into a mold, carrying out hot-pressing curing for 1-3 hours at 90-110 DEG C, heating to 130-150 DEG C, and continuing hot-pressing curing for 0.5-1 hour, so as to obtain the epoxy modified polyurethane film. The thermal decomposition temperature of the prepared epoxy modified polyurethane film reaches 300 DEG C or above, and the epoxy modified polyurethane film can be used for a long time in a high-temperature environment of 150 DEG C and has high tension, high tensile force, water resistance, air permeability, obdurability, aging resistance, cold resistance and chemical corrosion resistance.
本发明公开一种聚氨酯自粘胶膜防水卷材、制备方法及其应用，所述聚氨酯自粘胶膜防水卷材自上而下依次包括环氧改性聚氨酯膜、自粘胶层和保护衬垫；所述环氧改性聚氨酯膜的制备方法为：按质量份将10～15份反应型阻燃剂分散于20～30份四氢呋喃中，再与40～60份聚氨酯预聚体、15～20份环氧丙烯酸酯、5～10份氟化环氧树脂混合均匀后，加热至50～55℃预反应0.5～1h，再升温至70～80℃，加入1～2份双二甲氨基乙基醚，保温搅拌反应3～6h，再浇注至模具中，90～110℃热压固化1～3h，再升温至130～150℃继续热压固化0.5～1h，制得环氧改性聚氨酯膜。本发明制备的环氧改性聚氨酯膜热分解温度达300℃以上，可在150℃高温环境中长期使用，具有高张力、高拉力、防水透气性、强韧性、耐老化性、耐寒性、耐化学腐蚀性能。
