Abstract

The invention relates to special seal gum for a solar cell assembly and a manufacturing method thereof, which is suitable for the bonding fixation of solar panels, the seal of photovoltaic assembly aluminium sashes and the bonding seal of a junction box and a TPT / TPE back membrane. The special seal gum for the solar cell assembly comprises the following initial raw material components in parts byweight: 10-90 parts of terminal-based silane crosslinkable alpha-methyl polyethylene oxide, 1-10 parts of age inhibitor, 30-50 parts of stuffing, 1-50 parts of thixotropic agent, 1-10 parts of tackifier and 0.1-5 parts of catalytic curing agent. The seal gum has high curing speed, good sealability as well as yellowing resistance and deformation resistance of colloid, and can be suitable for the special sealing and bonding requirements of the solar assembly.

Description

technical field [0001] The invention relates to a special sealant for solar battery modules and a manufacturing method thereof, which is suitable for bonding and fixing solar battery panels, sealing aluminum frames of photovoltaic modules, and bonding and sealing junction boxes and TPT / TPE back films. Background technique [0002] Silicone sealant is a relatively common sealing material, which is mainly used in fireproof sealing of buildings, flame retardant sealing of cables through walls and other applications. Existing silicone sealants still have deficiencies in the comprehensive indicators of sealing and bonding performance, flame retardant and fireproof performance, insulation performance, and aging performance, and it is difficult to meet the use requirements of solar modules under specific working conditions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a special sealant for solar cell modules with fas...
