Abstract

The invention discloses a silane modified polyether sealing mildew-proof adhesive and a preparation method thereof. The silane modified polyether sealing mildew-proof adhesive is characterized by comprising the following main components: silane modified polyether resin, a nano filler, a thixotropic agent, a mildew-proof agent, a plasticizer, a silane coupling agent, titanium dioxide, a water removal agent and a catalyst. A silane modified polyether ether sealant relates to the field of silane modified polyether sealant mildew-proof adhesives and comprises the following components in parts by mass: 80-100 parts of modified polyether, 50-100 parts of a plasticizer, 250-300 parts of nano calcium carbonate, 2-3 parts of a thixotropic agent, 0.25-0.5 part of a mildew inhibitor, 30-38 parts of a dehydrating agent, 4-8 parts of a silane coupling agent and 0.5-1 part of a catalyst. The silane modified polyether sealing mildewproof glue with excellent mildewproof and moisture-proof performance prepared by the invention has the advantages that the service life is prolonged, the surface drying and viscosity eliminating time is short, and better elongation and yellowing resistance can be kept. The preparation method is simple, the process can be used for industrial production, the cost is low, the energy consumption is small, and good economic benefits and social benefits are achieved.

Description

technical field [0001] The invention relates to the field of application of silane-modified polyether sealing anti-mildew glue, in particular to a silane-modified polyether sealing anti-mildew glue with excellent anti-mildew properties and adhesion properties and a preparation method thereof. Background technique [0002] In the interior decoration of the home, such as kitchens, toilets, toilet sanitary ware and countertops, basement walls and other places, because the environment is relatively humid, it is very easy to breed mold, causing the decorative coating to fade or even fall off, affecting the aesthetics of the building and causing safety problems. If humans are in this environment for a long time, it is easy to cause respiratory inflammation and allergic diseases, rhinitis, and seriously endanger human health. The sealant used in such an environment must have certain waterproof and mildew resistance requirements for its performance. sex. At present, the commonly us...
