Photovoltaic waterproof coiled material for roof and preparation method for photovoltaic waterproof coiled material

Abstract

The invention discloses a photovoltaic waterproof coiled material for a roof. The photovoltaic waterproof coiled material is in a layered structure and comprises a waterproof coiled material base material, a flexible membrane photovoltaic battery assembly, a membrane layer and a coating layer sequentially from inside to outside. The invention also discloses a method for preparing the photovoltaic waterproof coiled material for the roof. The method comprises the steps of (1) preparing the waterproof coiled material base material: cleaning one side of the surface of the waterproof coiled material base material for standby application; (2) preparing the photovoltaic battery assembly: coating the front face of the flexible membrane photovoltaic battery assembly which is provided with the surface packaged by a fluorine-containing TPT polyester membrane or an ethylene-tetrafluoroethylene copolymer membrane with a nanoscale silicone acrylic coating or a nanoscaleperfluorocarbon coating; (3) performing combining and packaging: performing stacking in the sequence of the flexible membrane photovoltaic battery assembly, a Sika single-component high-modulus polyurethane sealant and the waterproof coiled material base material, and performing roll pressing and laminating machine vacuum pumping, so that layers of elements are bonded closely, and a product is obtained. The preparation method is simple, low in cost, multiple in option of substrates and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the fields of building energy saving and photoelectric buildings, and relates to a photovoltaic building material applied to photovoltaic building integrated buildings, in particular to a roof photovoltaic waterproof coiled material and a preparation method thereof. Background technique [0002] The traditional roof is only a shelter from wind and rain. Long-term exposure to the sun and rain will cause aging and damage to the waterproof layer of the building roof, which not only reduces the use function of the building, but also reduces the service life of the building, and wastes a lot of sunlight resources. . How to change the adverse effects of sunlight on buildings into beneficial effects, convert sunlight into inexhaustible renewable energy, and meet the needs of green buildings for roof waterproofing, prolonging the service life of buildings, and self-consumption of electricity has become a Important research content in ...

AI Technical Summary

Problems solved by technology

At present, there are related technologies to bond flexible solar photovoltaic thin film battery modules such as amorphous silicon with TPO, EPDM, EPDM waterproof membranes or thermoplastic polyolefin waterproof membranes and modified asphalt waterproof membranes on the waterproof roof site. However, this process has problems such as complicated on-site operation, great influence on the quality of the environment and human factors, and high comprehensive cost.
