Problems solved by technology

However, epoxy resin sealant requires two-component mixing, which is time-consuming, labor-intensive, and material-intensive. At the same time, the presence of epoxy groups in the material itself and organic amines in the curing agent makes it impossible to fundamentally solve the problem of weather-resistant yellowing. The failure of the epoxy curing agent in the environment will cause the phenomenon of whitening of the surface of the material, which directly restricts its application in the beauty sewing industry

Abstract

The invention discloses a silane-modified polyether adhesive for the single-component tile seam decoration industry. The silane-modified polyether adhesive comprises, by weight, 20-60 parts of silane-terminated polyether, 20-50 parts of silicone resin, 1-10 parts of polyether polyol or diisodecyl ortho-phthalate, 1-5 parts of a dehydrating agent, 0.1-1 part of an antiager, 0.1-1 part of a hinderedamine light stabilizer, 1-20 parts of a filler, 1-5 parts of a tackifier, 5-15 parts of a crosslinking agent and 5-8 parts of a thixotropic agent. The filler comprises one or more of nano-titanium dioxide, carbon black, pearl powder and glitter powder. The tackifier is gamma-(2, 3-epoxypropoxy)propyltrimethoxysilane. The cross-linking agent is gamma-aminopropyltriethoxysilane. The thixotropic agent is fumed silica. The silicone resin is methoxy functional polyphenylmethylsiloxane. The adhesive is anti-mild, anti-black, excellent in weather resistance, excellent in anti-yellowing, non-whitening, excellent in bonding performances and convenient in operation.

Description

Technical field: [0001] The invention relates to a ceramic tile beautifying agent, in particular to a single-component silane-modified polyether adhesive for the ceramic tile beautifying industry. Background technique: [0002] In today's life, ceramic tiles are widely used for house decoration. They are durable and beautiful. They can be spread on the floor or on the wall. But after laying the tiles, we need to pay attention to a problem, that is, there will be certain gaps between the tiles. In the past, people used ordinary white cement for pointing and filling. Not only the surface is rough and dull, but more importantly, the surface of the gap will turn black or even fall off after two or three months, making it extremely difficult to clean. Not only is it not beautiful, but it is also easy to hide dirt and spread diseases. For beautification and sealing of tile gaps in home decoration, the performance requirements for sealing materials are sealing and waterproof, no ...
