Waterproof and anti-cracking ceramic tile seam filling adhesive

Abstract

The invention discloses a waterproof and anti-cracking ceramic tile seam filling adhesive. The waterproof and anti-cracking ceramic tile seam filling adhesive is prepared from the following raw materials in parts by weight: 70 to 90 parts of bisphenol A epoxy resin, 10 to 20 parts of a curing agent, 5 to 12 parts of antimony oxide, 1 to 9 parts of organic bentonite, 2 to 6 parts of kaolin, 2 to 8 parts of a toughening agent, 3 to 5 parts of an accelerant, 2 to 10 parts of p-dihydroxybenzene, 2 to 10 parts of nano wollastonite powder, 2 to 8 parts of cellulose nitrate and 3 to 10 parts of ethanol. The product provided by the invention has a good bonding performance and is tightly combined with material bodies on different base surfaces in a tile seam; meanwhile, the product is used for enabling an inner structure of a material to be more dense in a condensation period and can effectively prevent external water from permeating into a matrix from the tile seam, so that the stability and waterproof performance of a decorative system are improved.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a waterproof and crack-proof ceramic tile caulking adhesive. Background technique [0002] At present, the materials used for the construction of ceramic tile caulking and decoration in buildings are mainly cement-based materials, which are in the form of powder, and are generally packed in bags or barrels. Defects of cement-based joint filling materials: First, when the cement-based joint filling material is mixed on site, due to the characteristics of cement as a cementitious material, it must be used up within a specified time after mixing with water, otherwise it will be scrapped due to hardening and the material will be wasted big. Second, during construction, due to the skill of the construction personnel, the filling degree of the brick joints cannot be guaranteed, which directly affects the construction quality. The third is that the construction personnel use a sponge ...

Problems solved by technology

Defects of cement-based joint filling materials: First, when cement-based joint filling materials are mixed on site, due to the characteristics of cement as a cementitious material, it must be used up within the specified time after adding water and mixing, otherwise it will be scrapped due to hardening, and the material will be wasted Big

The second is that during construction, due to the technical quality of the construction personnel, the filling degree of the brick joints cannot be guaranteed, which directly affects the construction quality.

The third is that the construction personnel use a sponge scraper to press the cement-based caulking material into the brick joints on the brick surface, and at the same time pollute the surface of the tiles, which brings trouble to the construction, and takes a lot of work and effort.

Fourth, in the subsequent cleaning of the brick surface, the stability of the brick joints will be affected, and secondary pollution will be caused to the brick joints.
