Problems solved by technology

At present, the commonly used silicone sealants are all single-component, and their curing speed is slow and takes a long time, and they are easy to "overflow" in the production process of solar modules, which seriously affects production efficiency. At the same time, they are not effective in moisture-proof isolation. During long-term use, it seriously affects the anti-aging performance of the colloid, and at the same time affects the normal use of solar modules

Abstract

The invention discloses a solar cell back panel insulating rubber and a preparation method thereof. The insulating rubber comprises the following components in parts weight: 20-30 parts of hydroxyethyl methacrylate, 5-10 parts of nitrile-butadiene rubber, 6-10 parts of polyvinyl alcohol, 0.3-0.8 part of ammonium persulfate, 6-13 parts of vinyl acetate, 3-8 parts of microcrystalline wax, 4-8 parts of ester gum, 1-4 parts of n-butyl titanate, 2-5 parts of dimethyl siloxane, 2-7 parts of tritolyl phosphate, 1-4 parts of barium stearate, 1-3 parts of aluminum oxide, 0.3-0.8 part of ultraviolet absorbent and 0.5-1 part of antioxidant. The preparation method comprises the following steps: adding the components into a reaction kettle, mixing and stirring uniformly, heating to react in an inert gas protective atmosphere, and cooling to room temperature. The insulating rubber disclosed by the invention has the advantages of favorable water isolation effect, favorable adhesive property and favorable aging resistance, and is suitable for sealing isolation of the solar cell back panel.

Description

technical field [0001] The invention belongs to the technical field of sealing material preparation, and in particular relates to a solar cell backplane isolation glue and a preparation method thereof. Background technique [0002] Sealant is a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion. It is an adhesive used to fill the configuration gap and seal it. It has the functions of anti-leakage, waterproof, anti-vibration, sound insulation and heat insulation. Usually dry or non-dry viscous materials such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber are used as the base material, and inert fillers such as talcum powder, clay, carbon black, titanium dioxide and asbestos are added. Plasticizers, solvents, curing agents, accelerators, etc. [0003] A sealant is a flowable or extruded amorphous material to fill a closed joint that can rely on embedded drying, temp...
