Problems solved by technology
[0003] The gap fillers in the prior art usually use gelling materials as the connecting body. The disadvantage is that the glue is easily affected by temperature, resulting in cracks in the expanded state. Although some companies have added additives to maintain Internal tension and adhesion, but its cost is high, and its environmental performance is poor, so it cannot be recognized by the market

The invention discloses a joint mixture for a thermal insulation material and relates to the technical field of building thermal insulation materials. The joint mixture comprises Portland cement, talcum powder, cellulose ether, wood fibers, glass beads, acrylate, vinyl acetate and defoamer. The Portland cement and the talcum powder are adopted, the internal adhesive force can be improved through the wood fibers, the strength can be improved through the glass beads, the stability can be greatly improved through acrylate and vinyl acetate, bubbles are removed through the defoamer, and joints are prevented from being generated inside.
Description
technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a caulking agent used for filling gaps in building outer layers or floors. Background technique [0002] With the continuous development of the construction industry, the market demand for caulking agent as the connector of floor tiles is also increasing. At present, the caulking agent on the market is mainly cement caulking agent. [0003] The gap fillers in the prior art usually use gelling materials as the connecting body. The disadvantage is that the glue is easily affected by temperature, resulting in cracks in the expanded state. Although some companies have added additives to maintain Internal tension and adhesion, but its cost is high, and its environmental protection performance is poor, so it cannot be recognized by the market. Contents of the invention [0004] In order to solve the above technical problems, the present invention provid...
