Abstract

The invention relates to the technical field of building materials, particularly to a flexible sealant. The flexible sealant is composed of, by weight part, 10-20 parts of polyether polyol, 10-15 parts of toluene diisocyanate, 15-18 parts of hydroxyl-terminated polysiloxane, 2-5 parts of plasticizer, 7-10 parts of filler, 12-15 parts of quartz sand, 1-4 parts of inorganic pigments, 1-5 parts of defoamer, 1-5 parts of dispersant, 1-5 parts of antifreezing agent and 1-5 parts of coalescing agent. The flexible sealant has the advantages of high ductility, high elasticity, ageing resistance and high and low temperature resistance, is high in adhesion force on the contact face of the seams of ceramic tiles, and meanwhile, avoids powdering, yellowing, hardening and efficacy losing and achieves high flexibility.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a flexible beautifying agent. Background technique [0002] Considering the factors of thermal expansion and contraction, when laying tiles, a certain gap needs to be reserved between each tile, and these gaps need to be filled with a caulking agent. At present, the commonly used beautifying agents are ordinary cement-based joint sealants and reactive resin joint sealants. Common cement-based joint sealants generally use white cement, and white cement itself has high hardness after curing and insufficient flexibility. As a result, the joints are prone to cracking in the cold season. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of insufficient flexibility and easy cracking of the beauty joint agent in the prior art, and propose a flexible beauty joint agent. [0004] In order to achieve the above object, the pr...
