Problems solved by technology

The solar backsheet is one of the accessories of the whole solar cell. It mainly plays the role of mechanical support and protection of the cell from the penetration of environmental factors. At present, the traditional solar backsheet has poor tensile strength and is easy to be scratched and scratched during long-distance transportation. It greatly affects the service life of the backplane and reduces the light conversion efficiency

Embodiment Construction

[0021] Specific embodiments of the present invention will be described below.

[0022] A kind of production technology of scratch-resistant solar backboard comprises the following steps:

[0023] The first step: the PET base material is supplied by the unwinder;

[0024] The second step: uniformly coat the proportioned adhesive on one side of the PET substrate through a two-roller roller coating machine;

[0025] 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 100°C, and the drying time is 7 minutes;

[0026] Step 4: Composite a layer of scratch-resistant and wear-resistant coating on the surface of the PET-based material with adhesive; the scratch-resistant and wear-resistant coating is a fluororesin coating modified by a highly dispersed nanoporous gas phase SIO2 material, fluororesin The coating is polyvinylidene fluoride, polychlorotrifluoroethylene, polytetrafluoroe...

Abstract

The invention relates to a production process for a scraping-wearing-resistant solar back panel. The solar back panel produced by the production process comprises a PET base material, scraping-wearing-resistant coating and a coating layer. By setting the scraping-wearing-resistant coating on the surface of a weather-proof layer, the water vapor barrier property is improved; the water vapor transmittance can achieve 0.001g / m<2>.d; an effective scraping-wearing-resistant effect also can be achieved; the problem that the solar back panel is scraped and damaged easily in a transport process is avoided; and therefore, the service life of the solar back panel is greatly prolonged.

Description

technical field [0001] The invention relates to the field of solar modules, in particular to a production process of a scratch-resistant 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. It mainly plays the role of mechanical support and protection of the cell from the penetration of environmental factors. At present, the traditional solar backsheet has poor tensile strength and is easy to be scratched and scratched during long-distance transportation. It greatly affects the service life of the backplane and reduce...
