Description

technical field [0001] The invention relates to the technical field of solar silica gel panels, more specifically, the invention relates to a high-temperature-resistant and corrosion-resistant solar silica gel panel and a preparation method thereof. Background technique [0002] Silica gel sheet is an industrial rubber sheet made of silica gel as the main raw material. Gaskets, gaskets and seals can be punched, mainly used in food industry, machinery industry, electronic appliances, automobile industry, chemical industry, light industry, metal and paint and other fields. On the solar laminator, a silica gel plate is used as a backing plate. The silica gel plate divides the table top and the upper cover of the laminator into two chambers. Because it also has a certain degree of elasticity, the upper and lower chambers are vacuumed. At the same time, start to inflate the upper chamber to make it deform and exert pressure on the components located in the lower chamber. This is...
