Abstract

The invention discloses a waterproof anti-flaming photovoltaic coiled material. The photovoltaic coiled material sequentially comprises a transparent waterproof layer, a flexible photovoltaic module layer and a waterproof coiled material layer from top to bottom, and all layers are connected through grapheme modified epoxy adhesives. The transparent waterproof layer is a modified PE permeable film; the flexible photovoltaic module layer comprises a flexible thin film photovoltaic module, an ethylene-tetrafluoroethylene copolymer film layer and a graphene-silicone-modified polyacrylamide coating layer; and the waterproof coiled material layer sequentially comprises a reflecting film, a waterproof anti-flaming layer, a glass fiber mat layer and a self-adhered SBS modified asphalt layer fromtop to bottom, and the surface of the modified asphalt layer is provided with a PE protection layer. The waterproof anti-flaming photovoltaic coiled material is good in waterproof and anti-flaming performance, can fully realize the role of photovoltaic power generation, the production cost of the coiled material is low, the use is convenient, and the coiled material is suitable for popularizationand application.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic materials, in particular to a waterproof and flame-retardant photovoltaic coil and a preparation method thereof. Background technique [0002] Solar energy technology will become one of the green energy technologies in the future. Solar energy or photovoltaic (PV) is widely used in China, especially in recent years, as the production cost of polysilicon, the raw material of solar cells, has been greatly reduced, and the production technology of solar cells has been perfected day by day. The output of solar cells in the world has increased very fast in 2010, which can be said to be an extremely promising industry. [0003] At present, photovoltaic power generation is mostly selected on building roofs, and its photovoltaic power generation components mainly include crystalline silicon photovoltaic panels and amorphous silicon photovoltaic thin film battery coils. There are two ways to fi...
