Embodiment Construction

[0019] Specific embodiments of the present invention will be described below.

[0020] A kind of production technology of organic insulating type solar back panel comprises the following steps:

[0021] The first step: the PET base material is supplied by the unwinder;

[0022] The second step: uniformly coat the proportioned adhesive on one side of the PET substrate through a two-roller roller coating machine;

[0023] The third step: transport the PET substrate coated with the adhesive in the second step to a drying room for drying and curing, the drying temperature is 180°C, and the drying time is 10 minutes;

[0024] Step 4: compound a layer of organic insulating coating on the surface of the PET-based material with adhesive; the organic insulating coating is formed by mixing phenolic resin, epoxy resin, and amino resin, and the thickness of the organic insulating coating is 15 μm;

[0025] Step 5: Roll the PET substrate compounded with the organic insulating coating in ...

Abstract

The invention relates to a production process of an organic insulated solar backplate. The solar backplate produced according to the process comprises a PET substrate, an organic insulation layer and a coating layer. The solar backplate is simple in structure and is convenient to use, electrical insulativity, weather resistance, excellent resistance to water vapor permeability, anti-hydrolysis property and anti-ultraviolet property of the solar backplate can be integrally improved, and the requirement for non-aging after 25-year application is met; and with the arrangement of the organic insulation layer, the cooling performance and the water insulation property of the solar backplate can be substantially improved.

Description

technical field [0001] The invention relates to the field of solar modules, in particular to a production process of an organic insulating solar backboard. Background technique [0002] Solar energy, as a green and inexhaustible energy source, is undoubtedly the best choice to replace traditional thermal power generation. Since solar cells need to be exposed to the outdoors for a long time, the cells in photovoltaic modules need to be protected to prevent atmospheric pollution. The impact and overlooking of environmental factors such as water vapor, oxygen, and ultraviolet rays. The solar backsheet is one of the accessories of the whole solar cell, which mainly plays the role of mechanical support and protection of the cell from the penetration of environmental factors. Capacitance, electrical organic insulation and water vapor permeability resistance, it does not have long-term hydrolysis resistance, UV resistance and weather resistance.
