Problems solved by technology

On the other hand, the existing anti-mildew sealants all adopt appropriate anti-mold agents to achieve the anti-mold effect, such as organic phosphoric acid compounds, tetrachloroisobenzonitrile, methylsulfonyl, benzimidazole compounds, etc., such anti-mold compounds, etc. Mold agents often have an unstable structure, easy to decompose due to environmental temperature changes, and become invalid over time, and antifungal agents have certain physiological toxicity

Abstract

The invention discloses double-component mould-proof silane-modified polyether gum. The double-component mould-proof silane-modified polyether gum comprises a component A and a component B, wherein the component A is formed by the following components in parts by weight: 100 parts of a silane-modified polyether polymer, 20-50 parts of a plasticizer, 30-70 parts of reinforced filler, 40-80 parts ofcoarse whiting, 5-15 parts of titanium dioxide, 1-5 parts of a bonding accelerant, and 1-3 parts of a moisture scavenger; and the component B is formed by the following components in parts by weight:70-110 parts of the plasticizer, 90-130 parts of the reinforced filler, 40-80 parts of the coarse whiting, 5-15 parts of the titanium dioxide, 1-3 parts of a catalyst, 2-6 parts of deionized water, and 1-3 parts of an emulgator. The invention further provides a preparation method for the double-component mould-proof silane-modified polyether gum. The prepared sealing gum is lower in VOC, pollution-free to the environment, green and environmental, and has not physiological toxicity. In addition, the sealing gum has the long-acting anti-mould effect. The component A is better in storage stability, and can be stably stored for a long time.

Description

technical field [0001] The invention relates to a sealant, in particular to a two-component mold-proof silane-modified polyether glue and a preparation method thereof, belonging to the technical field of polymer materials and their preparation. Background technique [0002] With the improvement of people's requirements for interior decoration DIY and life taste, whether the interior decoration glue is green or not has attracted more and more attention. Traditional elastic sealants for construction, such as polysulfide rubber, polyurethane sealant and organic silicone glue, have their own defects. Polysulfide rubber has poor durability and resistance to deformation and displacement; while PU glue will cause environmental pollution during construction, and it is easy to foam in the presence of moisture; silicone glue has shortcomings such as polluting surrounding substrates, and its surface finish Poor, so environmentally friendly sealants are increasingly favored by the mark...
