Rubber sheet for solar industry and preparation process thereof

Abstract

The invention relates to a rubber sheet for solar energy industry and a preparation process thereof, the rubber sheet comprises a rubber body (1), the rubber body (1) comprises skeleton cloth (1.1) located in the middle, an upper rubber layer (1.2) and a lower rubber layer (1.3) which are respectively combined with the upper surface and the lower surface of the skeleton cloth, the upper surface ofthe upper rubber layer (1.2) is provided with two PTFE membranes (3) in the lengthwise direction, and the two PTFE membranes (3) are parallel to each other and are not in contact. The rubber sheet issimple in preparation and high in production efficiency and has certain compression and ductility.

Description

technical field [0001] The invention relates to a rubber sheet and a preparation process thereof, in particular to a rubber sheet used in the solar energy industry and a preparation process thereof, belonging to the technical field of rubber. Background technique [0002] At present, in the solar industry, it is necessary to use rubber sheets as the sealing structure of sealing components; however, conventional rubber sheets have poor weather resistance, poor surface corrosion resistance, and poor oxidation resistance, resulting in limited service life; for this reason Some companies apply anti-corrosion coatings on the surface of rubber sheets to increase their corrosion resistance; however, this type of structure is low in production efficiency, and secondly, it cannot make the thickness of the anti-corrosion coating uniform (especially the spraying method in the continuous production process) Third, the spraying preparation process will cause environmental pollution and d...

[0002] At present, in the solar industry, it is necessary to use rubber sheets as the sealing structure of sealing components; however, conventional rubber sheets have poor weather resistance, poor surface corrosion resistance, and poor oxidation resistance, resulting in limited service life; for this reason Some companies apply anti-corrosion coatings on the surface of rubber sheets to increase their corrosion resistance; however, this type of structure is low in production efficiency, and secondly, it cannot make the thickness of the anti-corrosion coating uniform (especially the spraying method in the continuous production process) Third, the spraying preparation process will cause environmental pollution and damage to the health of the spraying workers; and after spraying the coating, when the rubber plate is installed on the solar module during use, when the two sides of the rubber plate are under pressure, the rubber plate will be damaged. When extending, due to the lack of ductility of the coating, either the rubber sheet is limited and cannot be extended, or the hard extension causes cracks in the surface anti-corrosion coating, which affects its performance and appearance. Therefore, there is an urgent need for a solution that can solve the above problems problem rubber sheet
