Problems solved by technology

[0002] With the progress of society and the improvement of the quality of life of residents, traditional caulking agents, caulking adhesives and other series of products will appear discoloration, mold, and peculiar smell after long-term use, which brings a lot of inconvenience to residents' lives; more importantly, in Hotels, discos, conference rooms and other high-end places simply cannot achieve the noble, elegant, warm and luxurious decoration effect, which has always troubled people in the decoration industry
[0003] In the decoration industry, traditional caulking glue and caulking agent are roughly divided into three types: the first is white cement-based caulking agent, which is evenly mixed with white cement and fine sand, and the production process is simple, cheap and of poor quality. , the shortcomings are obvious; the second is a one-component water-based beautifying agent, which is made of polymers such as acrylic emulsion or water-based epoxy resin, and is dispersed by adding different powders and additives. This type of beautifying agent is developing rapidly. It has a wide range of applications, simple operation, and diverse colors, but it shrinks significantly after curing, and it is easy to hide dirt, mildew and black, which affects the appearance; the third is two-component or multi-component oily seam glue. The beautifying agent is very hard after curing, bright and bright in color, does not collapse, does not mold, and has a good aesthetics, but the construction process is complicated, and masking paper must be pasted, which is easy to contaminate the tiles, and the curing agent is toxic, not environmentally friendly, and harmful to the human body. harm

Abstract

The invention relates to a building sealant. The building sealant is prepared from the following components in parts by mass: 100 parts of hybrid resin, 0 to 20 parts of plasticizer, 100 to 400 parts of calcium carbonate, 0 to 3 parts of ultraviolet absorbent, 2 to 12 parts of silane coupling agent, 3 to 10 parts of silane crosslinking agent and 0 to 3 parts of catalyst. The building sealant has the beneficial effects that 1, the environment-friendly and non-toxic effects are realized, the emission of VOC (volatile organic compound) is zero, the harm to environments and human bodies is avoided, and the building sealant is a green product; 2, the construction technology is simple, the extrusion property is good, and the sagging and collapsing are avoided; 3, after curing, the adhering property on tiles, marbles and the like is good, the pollution to the tiles is avoided, the flatness is high, the color and luster is bright, the certain toughness is realized, the flushness of the tile joint and the tile surface is ensured, and the hollow and loosening are prevented; 4, after curing, the color is fresh, fine, smooth and uniform, and multiple colors can be matched according to requirements; 5, the waterproof and moistureproof effects are realized, the blackening and mildewing are avoided, the dirt is avoided, the cleaning is easy, and the building sealant is very suitable for high-grade workplaces of hotels, discos hall, luxury real estates, conference rooms and the like.
