Abstract

The invention relates to solar backboard glue and a preparation method thereof, and belongs to the technical field of solar glue. The solar backboard glue comprises the following raw materials by mass: 30-36 parts of ethylene vinyl acetate copolymer emulsion, 4-10 parts of polyurethane emulsion, 2-5 parts of epoxy resin, 7-14 parts of polyvinyl alcohol, 2-6 parts of turpentine, 5-12 parts of talcum powder, 8-14 parts of ethylenediaminetetraacetic acid, 6-10 parts of stearate magnesium, 15-19 parts of isopropyl alcohol and 25-33 parts of water. The solar backboard glue can form a soft and dense solar backboard glue layer, has good low temperature resistant and waterproof performances, good aging resistant performance, good softness, and good water vapor barrier property.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a solar backboard adhesive and a preparation method thereof. Background technique [0002] Adhesive refers to a natural or synthetic, organic or inorganic substance that can connect two or more parts or materials together through the adhesion and cohesion of the interface, also known as bonding. Agent, customarily referred to as glue. In short, an adhesive is a substance that can bind adherends together through bonding. "Adhesive" is a general standard term that also includes other glues, putties, mucilages, plasters, etc. [0003] The solar backsheet is located on the back of the solar panel, which protects and supports the battery sheet, and has reliable insulation, water resistance, and aging resistance. Generally has a three-layer structure (PVDF / PET / PVDF), the outer protective layer PVDF has good environmental erosion resistance, the middle layer is PET poly...
