Resin PTFE weather-resistant self-adhesive waterproof coiled material and preparation method thereof
The invention is suitable for the field of waterproof materials, and provides a resin PTFE weather-resistant self-adhesive waterproof coiled material and a preparation method thereof. The resin PTFE weather-resistant self-adhesive waterproof coiled material comprises a PTFE film, a PET film, a PE film arranged between the PTFE film and the PET film, and a modified asphalt matrix; wherein the modified asphalt matrix comprises the following components: resin modified asphalt, rubber modified asphalt, a modifier, base oil, silica powder and ground calcium carbonate powder; the resin modified asphalt comprises the following components: soya oil acid, pentaerythritol, phthalic anhydride, lithium hydroxide and asphalt; the rubber modified asphalt comprises the following components: SBR styrene-butadiene rubber, SBS styrene-butadiene rubber, rubber powder and asphalt. According to the modified asphalt matrix provided by the invention, the weather resistance of the waterproof coiled material can be improved, the balance between the breaking strength and the elongation at break is enhanced, and the cohesiveness and the weather resistance of the waterproof coiled material can be improved.
本发明适用于防水材料领域，提供了一种树脂PTFE耐候型自粘防水卷材及其制备方法，该自粘防水卷材包括：PTFE膜；PET膜；设置在所述PTFE膜与所述PET膜之间的PE膜；以及改性沥青基体；其中，改性沥青基体包括以下组分：树脂改性沥青、橡胶改性沥青、改性剂、基础油、硅微粉、重钙粉；其中，树脂改性沥青包括以下组分：豆油酸、季戊四醇、苯酐、氢氧化锂、沥青；橡胶改性沥青包括以下组分：SBR丁苯橡胶、SBS丁苯橡胶、橡胶粉、沥青。本发明提供的改性沥青基体可以提高防水卷材的耐候性，加强其断裂强度和断裂伸长率之间的平衡性，以及可以提高防水卷材的粘结性和耐候性。
