Abstract

The invention relates to the field of waterproof coiled materials, and provides a waterproof coiled material and a preparation method thereof. The preparation method of the waterproof coiled materialcomprises the following steps: uniformly stirring raw materials such as polytetrafluoroethylene, tackifying resin, graphene, fibrillated glass fibers and the like, carrying out extruding and rolling to obtain a polytetrafluoroethylene layer, and carrying out one-time lamination on the polytetrafluoroethylene layer with a polypropylene filament non-woven fabric to obtain a polytetrafluoroethylene-polypropylene composite layer; sequentially depositing cadmium sulfide and zinc oxide on a copper indium selenide (CIS) battery thin film to prepare a composite semiconductor CIS battery piece; and sequentially bonding a polyvinyl chloride (PVC) soft crystal plate, the composite semiconductor CIS battery piece, a polyester cloth layer, a metal fiber sound absorption layer, the polytetrafluoroethylene-polypropylene composite layer and a base layer to prepare the waterproof coiled material. The waterproof coiled material can absorb solar energy and store the solar energy. Meanwhile, characteristics of flame retardancy, high-temperature resistance, high strength and the like are achieved, fireproof performance is enhanced, and application range of the waterproof coiled material is expanded.

Description

technical field [0001] The invention relates to the field of waterproof coiled materials, in particular to a waterproof coiled material and a preparation method thereof. Background technique [0002] Waterproof membrane is an important material basis for construction, urban construction, and road construction. As an important branch of waterproof materials, the performance and quality of waterproof membranes will directly affect the quality and service life of infrastructure construction. The waterproof membrane used for the roof is prone to aging and damage due to long-term exposure to the sun and rain. At the same time, the functional diversity of the waterproof membrane used as the roof also needs to be improved. The roof is an effective place for solar energy utilization. In today's society, people have placed a large number of solar panels for solar water heaters on the roof to improve the utilization of solar energy. s concern. How to use solar energy in the process ...
