One-component beautifying agent with high solid content and preparation method thereof

Abstract

The invention provides a one-component beauty joint agent with high solid content, which comprises 20-30 parts by weight of silicone acrylic emulsion, 5-8 parts of pearlescent pigment, and 55-70 parts of transparent filler , 0.2-0.5 parts of preservatives, 0.2-0.5 parts of fungicides, 0.2-0.5 parts of defoamers, 0.2-0.5 parts of thickeners and 1-1.5 parts of film-forming aids, of which silicone acrylic emulsion It is a copolymer emulsion of organosiloxane and acrylate, the pearlescent pigment is pearlescent pigment powder with a particle size of 400 mesh to 800 mesh, and the transparent filler is nano fumed silica. The beautifying joint agent of the present invention has high solid content and can effectively solve the problem of severe shrinkage after construction and cannot be molded at one time. It has soft pearl luster and rich colors, as well as high waterproof performance and good weather resistance, which is especially suitable for Use as a grout for high-grade tiles, mosaics or stone. The present invention also provides a preparation method of the above-mentioned one-component beauty joint agent with high solid content.

Description

Technical field [0001] The invention relates to a sealant, in particular to a beautifying agent whose decoration and practicability are obviously better than that of a colored sealant, and more specifically to a one-component beautifying agent with high solid content. The invention also relates to a preparation method of the above-mentioned beautifying seam agent. Background technique [0002] With the development of society, tiles, mosaics or stone have become one of the most commonly used materials in the field of architectural decoration. In order to facilitate transportation and storage, the size of the finished ceramic tiles, mosaics or stones should not be too large. Therefore, to form the entire wall or floor, it needs to be tiled piece by piece. Considering the factors of thermal expansion and contraction, In the process of laying ceramic tiles, mosaics or stone, certain gaps need to be reserved between the blocks, and these gaps need to be filled with a caulking agent. ...

AI Technical Summary

Problems solved by technology

However, the solid content of the beautifying agents currently on the market is relatively low, and the gaps between tiles are generally 5-10mm deep. When using beautifying agents for caulking, there are often cases where the paint film shrinks severely after drying and requires secondary caulking. Disadvantages: The essential reason for the low solid content lies in the high price of pigments. Adding a large amount of pigments can certainly increase the solid content of the product, but it also leads to high product costs and affects market competitiveness. However, the solid content of the emulsion itself is low, generally only at 45 % to 50%, and by adding other fillers to increase the solid content of the system, there is a problem that the filler will cover the pigment luster and seriously affect the appearance. Various reasons make the solid content of the existing beautifying agent low, and the product has obvious shrinkage
