Abstract

The invention relates to an environment-friendly MS sealant and a preparation method thereof. Component A of the environment-friendly MS sealant is compounded with a specific proportion of silicone-modified polyether polymer, filler, plasticizer, molecular sieve, etc. Group B The plasticizer, aging-resistant silane additive, carbon black and catalyst are compounded in a specific proportion, and the aging-resistant silane additive is made of a specific proportion of coupling agent, cross-linking agent and chain extender under vacuum at 120±10°C It is prepared by stirring and reacting for 7-9 hours under the condition. The environmentally friendly MS sealant containing anti-aging silane additives and molecular sieves can meet the needs of the second sealing process of insulating glass, and can effectively improve the water and UV resistance, and has low TVOC, environmental protection and odorless.

Description

Technical field [0001] Technical Field The present invention relates to adhesives, in particular, it relates to environmentally friendly MS sealant preparation method thereof. Background technique [0002] Hollow glass having insulation because, energy, sound, light transmitting properties are widely used in modern construction, due to its superior performance using sealants peripheral seal. [0003] Currently, hollow glass is usually carried out in two sealing processing step, the first sealing step is performed using butyl rubber track, it is to pre-position, isolated from water vapor; secondary seal step is often used polysulfide sealant or silicone sealant plastic, glass bonding effect sealing. A secondary sealing step is critical to the life of insulating glass, where higher adhesive strength compared with excellent corrosion sealant aging properties. However, many silicone sealants on the market products difficult to meet GB / T 29755 elastic sealant for insulating glass st...
