The butyl adhesive layer is connected with the release film layer in a stripping manner, and the butyl adhesive layer is used for being connected with the photovoltaic roof when the butyl adhesive layer is stripped from the release film layer. The clearance hole has been seted up on the fluorine carbon film layer, and the clearance hole is used for wearing to establish photovoltaic module, is provided with porous rough surface on the fluorine carbon film layer, and porous rough surface is connected with the butyl rubber layer, and butyl rubber layer part inlays on the fluorine carbon film layer, and the butyl rubber layer is used for the adhesion on wearing to locate the photovoltaic module in clearance hole. Foretell waterproofing membrane for photovoltaic roofing has longer life and can alleviate the roofing problem of leaking that causes when photovoltaic module installs.
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 of the waterproof coiled material and a photovoltaic roof construction structure.
Background
Under the policy of double carbon, new energy, especially photovoltaic power generation which is one of green energy, is vigorously developed in the whole society. The equipment cost that photovoltaic power generation drops into is higher, need longer time to reach and withdraw economic benefits, regard as photovoltaic power generation's roofing promptly, need have longer service life to support photovoltaic power generation's long-term productivity, generally use the operation age to be about 25 years, and because photovoltaic module's mounting process is mostly the penetrating type, can cause the roofing to leak, photovoltaic roofing in case the seepage takes place, photovoltaic module's operation will be greatly influenced, and then need carry out waterproof overhaul, and photovoltaic module of photovoltaic roofing needs dismouting again can carry out the waterproof overhaul of roofing, the work load is great, it is time-consuming and energy-wasting, in addition, the waterproof life of the waterproofing membrane who generally uses after the overhaul is shorter, mismatch with photovoltaic power plant's life cycle, and then cause and need dismouting many times during photovoltaic module's operation, influence photovoltaic module's long-term productivity.
