Abstract

The invention provides a single-component silane-modified polyether sealant and a production method and application thereof, and belongs to the field of building sealants. The sealant comprises the following raw materials of, in parts by weight, 20-50 parts of silane-modified polyether resin, 0-15 parts of plasticizer, 30-60 parts of filler, 1-2 parts of thixotropic agent, 0.4-1.5 parts of functional assistant, 0.5-2 parts of moisture scavenger, 0.5-2 parts of bonding accelerator and 0.05-0.5 part of catalyst. The sealant is excellent in weather resistance performance, the phenomena of cracking and efflorescence are not liable to occur, and no pollution is caused for a stone curtain wall.

Description

technical field [0001] The invention relates to the field of building sealants, in particular to a one-component silane-modified polyether sealant and its preparation method and application. Background technique [0002] Sealant is a material used to fill gaps. It is a fluid or paste-like amorphous material during construction. After construction, it relies on solvent volatilization or chemical reaction to bond with the substrate to play the role of bonding, fixing and sealing. . Silane-modified polyether sealant, because it combines the advantages and strengths of silicone sealant and polyurethane sealant, has excellent durability, high resistance to deformation and displacement, good adhesion, paintability, and environmental friendliness The advantages of non-toxicity, low staining, low viscosity and good workability have attracted more and more attention from the domestic construction industry. [0003] The traditional stone curtain wall caulking glue is mainly silicone...
