Abstract
The invention relates to a neutral transparent silicone weather-resistant sealing adhesive for a building and belongs to the technical field of adhesives. The neutral transparent silicone weather-resistant sealing adhesive is composed of 80-120 parts of alpha, omega-dihydroxyl poly-di-organosiloxane, 20-120 parts of alkyl terminated polydimethylsiloxane, 10-50 parts of fumed silica, 5-20 parts of a cross-linking agent, 1-5 parts of a tackifier and 0.05-0.5 part of a catalyst. The neutral transparent silicone weather-resistant sealing adhesive for the building has the advantages of high transparency, good adhesion performance, good weather resistance, high curing speed, small odor, no corrosion to most of base materials by neutral curing and the like, and can be applied to weather-resistant sealing of building engineering such as suspended glass walls, frame-hidden glass curtain walls and glass day-lighting roofs.
Description
Technical field
The present invention relates to a kind of neutral transparent silicone weatherproof sealant for building and preparation method thereof, belong to field of adhesive technology.
Background technology
Along with the fast development of China's economy, various types of urban architecture is maked rapid progress, people are more and more higher for the requirement of building energy conservation, waterproof, the aspect such as heat insulation and comfortable, the sealing of building joint is also more and more by construction industry is paid attention to simultaneously, and this facilitates the development of building joint seal gum undoubtedly greatly.Silicone sealant is with the weather-resistant performance of its brilliance, excellent high and low temperature resistance, and good hydrophobicity, stopping property, adhesiveproperties are widely used in the weather-proof joint seal of various glass curtain wall, aluminium veneer curtain wall, stone curtain wall etc., play bonding, sealing, waterproof, the multiple efficacies such as weather-proof.
Traditional silicone sealant belongs to de-acetic acid type seal gum, the micromolecular acetic acid can released when solidifying, during solidification smell large and have corroding metal base material and can with the shortcoming such as basic material reacts, greatly limit the range of application of this kind of seal gum, carry out the research work of neutral curing system silicone sealant both at home and abroad one after another.Neutral curing silicone sealant on domestic market using calcium carbonate etc. as reinforced filling, often causes the finished product opaque often, has a strong impact on the aesthetic of building when being applied to glass curtain wall etc. and being architectural.Therefore, Development of New Generation smell is little, transparency is high, the novel silicone weatherproof sealant little to metal base corrodibility seems particularly important.
