Non-cement-based caulking compound and construction method thereof

Abstract

The invention relates to a non-cement-based caulking compound. The non-cement-based caulking compound is prepared from the following raw materials by weight: 10 to 20 parts of acrylic acid copolymerization emulsion, 40 to 60 parts of heavy calcium carbonate, 28 to 40 parts of quartz powder, 3 to 5 parts of metakaolin, 0.06 to 0.1 part of hydroxypropyl methyl cellulose ether, 4 to 5 parts of titanium dioxide, 0.4 to 0.6 part of a water reducer, 0.2 to 0.3 part of a water repellent, 0.2 to 0.3 part of a liquid antifoaming agent, 0.4 to 0.6 part of an antiseptic, 0.1 to 0.3 part of a wetting dispersant, 0.2 to 0.5 part of aluminum-magnesium silicate and 0.1 to 0.2 part of an anti-skinning agent. 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, and 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 and enables cost to be saved; and in construction, the caulking compound can be applied in a manner resembling squeezing of toothpaste out of a tube, so production and construction steps are simplified.

Description

technical field [0001] The invention relates to a non-cement-based joint filler 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 non-cement based joint filler and its construction me...
