Abstract

The invention discloses an efficient polished brick antifouling agent and a preparation method thereof and belongs to the technical field of building material aids. A lubricating additive prepared bythe method successfully synthesizes polysiloxane with silicone wax and epoxy group composited, so that the antifouling agent is easy in spreading on the surface of a polished brick, and the surface layer of the polished brick is a hydrophobic antifouling surface layer; an antifouling surfactant prepared by the method utilizes reaction activity of the epoxy group for polymerization, and a bactericidal active agent is introduced on polymer molecular chain to inhibit growth of thalli on the surface layer of the polished brick; an antistatic additive prepared by the method utilizes active group and amino at the terminal of side chain, so that durability and water resistance of a polished film are improved, and glossiness durability is improved. The hydrophobic antifouling layer is formed by the lubricating additive, the antifouling surfactant is utilized for directional adsorbing sterilization of the polished brick, and infiltrating performance is utilized to act on the inside of the polished brick to prevent loss of the antifouling agent. The problem that existing antifouling bricks are low in antifouling efficiency is solved.

Description

technical field [0001] The invention belongs to the technical field of building material additives, and in particular relates to a high-efficiency polished brick antifouling agent and a preparation method thereof. Background technique [0002] Polished tiles have been favored by consumers as soon as they came out, and have now become the main product for shopping malls and residential floors and foyer decoration. The sintering of tiles can only eliminate the pores on the surface, but there are still 4%~5% closed pores in the ceramic body. When the surface of the tile is polished, these closed pores are exposed on the surface of the tile, forming open pores, which makes the surface of the polished tile as bright as a mirror less antifouling. In order to improve the anti-fouling of polished tiles, the vitrification degree of tiles has been improved and the water absorption rate has been reduced by changing the material composition of tiles, or coating a layer of dense materia...
