Bright caulking compound and construction method thereof

Abstract

The invention relates to a bright caulking compound. The bright caulking compound is prepared from the following raw materials by weight: 35 to 45 parts of common white Portland cement, 20 to 40 parts of quartz powder, 5 to 10 parts of light calcium, 1 to 3 parts of starch, 10 to 30 parts of heavy calcium carbonate powder, 0.15 to 0.25 part of hydroxypropyl methyl cellulose, 5 to 10 parts of pure acrylic glue powder, 0.08 to 0.1 part of a polycarboxylate superplasticizer, 0.1 to 0.3 part of an antifoaming agent, 0.2 to 0.3 part of an organosilicon water repellent, 0.1 to 0.4 part of aluminum-magnesium silicate, 0.4 to 0.6 part of a brightener, 1.5 to 3 parts of pigment, 0.3 to 0.5 part of a dispersant and 0.1 to 0.3 part of cellulosic fiber. According to the invention, since various properties of the caulking compound are improved through addition of proper additives, disadvantages of traditional cement-based caulking compounds are overcome, problems of a reactive resin type caulking compound are perfectly solved, the caulking compound disclosed in the invention has excellent resistance to corrosion, mildew, permeation, water, scrubbing, wear and contamination, excellent shrinkage deformation capability and other excellent properties, cost is saved, and production and construction steps are simplified.

Description

technical field [0001] The invention relates to a glossy caulking agent and a construction method thereof. Background technique [0002] At present, there are common cement-based caulks and reactive resin-based caulks on the market. Ordinary cement-based sealants have two major disadvantages: on the one hand, due to poor waterproof and impermeability, water is easy to penetrate in, resulting in mildew, and the tiles are easy to shrink and hollow; on the other hand, the surface has poor wear resistance and is easy to be polluted However, the reactive resin caulking agent can overcome the above disadvantages, but the cost of materials and packaging is too high, the production and mixing process is cumbersome, and it contains toxic and harmful gases such as VOC. , so that its application is limited. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a glossy caulking agent and its construction method, which are ...
