The component B isan epoxy resin amine curing agent. The prepared sterilization sealant is excellent in comprehensive performance, capable of meeting the requirement for building ceramic tile seam filling, attractive,elegant, rich in color, natural and fine.

Description

technical field [0001] The invention relates to the field of beautifying agents, in particular to a bactericidal beautifying agent for filling gaps in ceramic tiles and a preparation method thereof. Background technique [0002] With the progress of society and the rapid development of the decoration industry, people have higher and higher requirements for the beauty of home decoration, especially in the beautification and modification of the gaps between decoration materials, which are increasingly paid attention to. For example, during the construction of ceramic tiles, one of the most commonly used materials in the field of architectural decoration, considering the factors of thermal expansion and contraction, certain gaps need to be reserved between the tiles. Fill and decorate it with caulking agent. The performance of the caulking agent directly affects the effect of home decoration. [0003] At present, the sealants usually used to fill the gaps of tiles are ordinar...

Problems solved by technology

However, the beautifying agent paint film in the prior art shrinks severely after drying, and secondary caulking is required. The cured film is relatively soft. If it is scrubbed for a long time, it is prone to scratches and abrasions, which will affect the appearance of the later stage. , it is more or less expensive, and the materials used are toxic and not environmentally friendly. After a long time, there will be cracks and dents in the brick joints, which not only affect the aesthetics of the ground and walls, but also affect the The service life of ceramic tiles is seriously detrimental to the construction quality of decoration.
