Abstract

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.

Description

Technical field [0001] The present invention relates to the field of waterproof techniques, and more particularly to a thermostatic waterproof web having a roof and a preparation method thereof. Background technique [0002] With the increasing lack of natural resources, the material savings in the field of civil construction engineering are increasingly valued. As the waterproofing web for engineering waterproof, it can effectively prevent the leakage of civil construction projects, especially for engineering waterproof for buildings with long service, and in the face of heat insulation in the face of cold and hot weather. I have gradually become the focus of people. [0003] The existing roof is typically insulated with insulation, and during long periods of use, the waterproof layer and the heat insulating layer are prone to delash, so that the rain water penetrates into the insulator, resulting in the effect of insulating waterproof. Inventive content [0004] It is an objec...
