Photovoltaic waterproof coiled material for roof and preparing method

Abstract

The invention discloses a photovoltaic waterproof coiled material for a roof and a preparing method. The waterproof coiled material comprises a waterproof protection layer, a flexible photovoltaic assembly layer and a waterproof coiled material layer from top to bottom in sequence, and all the layers are bonded to one another through adhesive; the flexible photovoltaic assembly comprises a flexible thin film photovoltaic assembly, an ethylene-tetrafluoroethylene copolymer layer and a graphene-organosilicone modified polyacrylamide coating layer. The preparing method comprises the steps of firstly, preparing all layers of assemblies, then bonding all layers of assemblies in sequence, and placing the assemblies in a roller press and a laminating machine to be subjected to vacuum processing to make all layers of assemblies tightly combined, so that the photovoltaic waterproof coiled material is obtained. The photovoltaic waterproof coiled material can sufficiently utilize the light energyof the roof and increase the energy utilization rate, and also has a good waterproof and preservative effect, the service life of the waterproof coiled material is greatly prolonged, the using cost is lowered, and the application prospect is good.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a photovoltaic waterproof membrane for roofs and a preparation method. 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 the field of photovoltaic architecture. The roof is the most convenient and effective place to use solar energy, and it is the first choice ...

AI Technical Summary

Problems solved by technology

At present, roof photovoltaic power generation mainly adopts the form of installing crystalline silicon photovoltaic panels. There are usually two ways to fix crystalline silicon photovoltaic panels on the roof of a building: one is to use its own weight or increase the pressure, and place it directly on the roof. Due to the load Large, it cannot be applied on light-duty roofs and long-span roofs, and it is not easy to apply on exposed waterproof roofs, because the component force of the inclined and heavy battery panels will generate positive pressure on the exposed roof membranes, and long-term effects will damage roof waterproofing Another way of fixing is that the fixing part penetrates the waterproof layer of the roof membrane and is fixed with the roof structure layer, which will destroy the waterproof layer and have hidden dangers of penetration, which does not meet the basic principles of waterproofing

There are safety hazards such as wind exposure in the above two fixing methods.

In addition to the damage to the waterproof layer, the crystalline silicon photovoltaic panel installation system also has unfavorable factors such as increasing the building's load bearing and the risk of high-rise wind exposure, which affects the appearance of the building.
