Abstract

The invention discloses a single-component deoximation type sealing adhesive for a solar module. The starting materials of the sealing adhesive comprise the following components in parts by weight: 100 parts of No. 107 adhesive (polyvinyl formal adhesive), 1-20 parts of dimethicone, 50-100 parts of calcium carbonate, 3-20 parts of silicon dioxide, 10-50 parts of flame retardant, 5-15 parts of cross-linking agent, 0.5-3 parts of silane coupling agent and 0.2-1 part of catalyst. The sealing adhesive has good sealing, higher elongation and low contractility, is environmentally-friendly, waterproof and anti-fouling, does not corrode metals, resists hail impact and has good insulativity against high-voltage electricity and excellent resistance against high temperature, high humidity, aging and ultraviolet ray, can be widely used for sealing of solar module side frames and solar lamps and adhesive sealing between the outer frame and junction box of a photovoltaic solar panel module as well as in some places with high requirements for weatherability, airtightness and the like.

Description

technical field [0001] The invention relates to a sealant, in particular to a one-component deoxime type sealant for solar modules. Background technique [0002] Silicone sealant is characterized by high temperature resistance, low temperature resistance, corrosion resistance and radiation resistance. At the same time, it has excellent electrical insulation, water resistance and weather resistance. It can be bonded to metal, plastic, rubber, glass, ceramics, etc., and has been widely used in bonding and sealing of solar cell components, aerospace, aircraft manufacturing, electronics industry, machining, automobile manufacturing, construction and medical treatment. However, the existing silicone sealants still have deficiencies in the comprehensive indicators of flame retardancy, sealing, environmental protection, curing speed, aging, etc., and it is difficult to meet the use requirements of solar modules under specific working conditions. Contents of the invention [000...
