Heat-insulation waterproof roll for roofs and preparation method thereof
The invention discloses a heat-insulation waterproof roll for roofs and a preparation method thereof. The heat-insulation waterproof roll is prepared by bonding the upper face and the lower face of a heat insulation layer to a waterproof layer through a binder, the heat insulation layer is high in porosity and small in volume density and has a developed specific surface area, and therefore the prepared waterproof roll has a good heat-insulation effect; aluminum hydroxide reacts with phosphoric acid to form a phosphate solution, the phosphate solution is blended with polyurethane to obtain a binder, the binder contains a large amount of phosphate, the phosphate has a certain binding effect, and meanwhile the surface of the heat insulation layer contains a large amount of nano titanium dioxide, one phenolic hydroxyl group on a catechol group in the binder is chelated through nitrogen atoms and peroxide atoms and active hydroxyl groups on the surface of titanium dioxide, the other hydroxyl group and adjacent catechol form hydrogen-bond interaction, and the binder and active hydroxyl groups on the surface of a glass fiber felt in the waterproof layer are chelated; and the heat insulation layer and the waterproof layer are tightly bonded.
本发明公开了一种屋顶用隔热防水卷材及其制备方法，该隔热防水卷材通过粘结剂将隔热层的上下两面粘接防水层制得，该隔热层的气孔率高，体积密度小，具有发达的比表面积，使得制备出的防水卷材具有很好的隔热效果，通过氢氧化铝与磷酸反应形成磷酸盐溶液与聚氨酯共混得到粘结剂，该粘结剂含有大量磷酸盐，磷酸盐具有一定粘结效果，同时隔热层表面含有大量纳米二氧化钛，粘结剂内部的邻苯二酚基团上一个酚羟基通过氮原子螯合通过过氧原子与二氧化钛表面的活性羟基产生螯合，另一个羟基与相邻邻苯二酚形成氢键作用，且粘结剂与防水层中玻纤毡表面活性羟基产生螯合，使得隔热层和防水层粘结紧密。
