Abstract

The invention provides an environment-friendly mildewproof silicone-modified polyether sealant. The sealant is prepared from the following components in parts by weight: 20 to 50 parts of silicone-modified polyether resin, 10 to 25 parts of a plasticizer, 20 to 60 parts of filler, 1 to 10 parts of a colorant, 0.1 to 1 part of an ultraviolet light absorber, 0.1 to 1 part of a light stabilizer, 0.1 to 5 parts of a thixotropic agent, 0.01 to 1 part of a mildew preventive, 0.1 to 2 parts of a moisture scavenger, 0.1 to 2 parts of an adhesion promoter, and 0.1 to 1 part of a catalyst. The silicone-modified polyether sealant has stable elasticity and long-acting mildewproof performance; the environment-friendly plasticizer and catalyst are selected, so that the silicone-modified polyether sealant is odor free and relatively low in toxicity, and applicable to sealing and water proofing for household kitchens, toilets and other places in which mildew easily develops, and can replace traditional large-odor and poor-elasticity silicone sealant.

Description

technical field [0001] The invention relates to a sealant based on silane-modified polyether resin (MS-polymer), which has high elasticity, low odor and low toxicity, and is suitable for sealing and waterproofing in engineering machinery, rail transit and other industries, especially for home interior decoration. Such as kitchens, bathrooms and other humid environments, long-term stability and mildew resistance. Background technique [0002] In daily life, the sealants used in long-term humid environments such as kitchens and bathrooms are prone to breed mold, and mold can easily cause human respiratory system, skin and other body diseases, which is very harmful. At present, most of the kitchen and bathroom anti-mildew sealants commonly used in the market are deacidified or deketoxime-type silica gel, which is prepared by adding anti-fungal agents. The removed small molecules have a large odor, which is irritating to the respiratory tract and skin, and is environmentally fri...
