Description
Technical Field
The invention relates to the technical field of waterproof coiled materials, in particular to a waterproof coiled material for a photovoltaic roof, a preparation method thereof and a photovoltaic roof construction structure.
Background
Under the double-carbon policy, new energy sources, especially the photovoltaic power generation of one of green energy sources are greatly developed in the whole society. The equipment cost that photovoltaic power generation was thrown into is higher, needs longer time to reach and regain economic benefits, promptly as photovoltaic power generation's roofing, needs longer life to support photovoltaic power generation's long-term productivity, general service life is about 25 years, and because photovoltaic module's installation technique mostly is the through-type, can cause the roofing to leak, photovoltaic roofing once take place the seepage, photovoltaic module's operation will be greatly influenced, and then need carry out waterproof repair, and photovoltaic roofing's photovoltaic module need the dismouting again just can carry out the waterproof repair of roofing, the work load is great, waste time and energy, in addition, waterproof life-span of waterproofing membrane who generally uses after the repair is shorter, and the life mismatch with photovoltaic power plant, and then cause the long-term productivity that needs dismouting many times, influence photovoltaic module in photovoltaic module's operation period.
