Abstract

The invention provides caulking gypsum with high crack resistance. The caulking gypsum is prepared from the following components: 39 to 55 parts of gypsum powder, 10 to 15 parts of desulfurized gypsum, 12 to 18 parts of cement, 0.4 to 0.6 part of a water-retaining agent, 10 to 14 parts of glass beads, 2 to 3 parts of redispersible latex powder and 100 parts of water, the caulking gypsum has the beneficial effects that the tensile strength and the crack resistance of the caulking gypsum are improved by adding the cement and the redispersible latex powder into the caulking gypsum, so that the caulking gypsum with high crack resistance is obtained, and the high crack resistance requirement of the caulking gypsum is met.

Description

technical field [0001] The invention relates to the technical field of gypsum, in particular to caulking gypsum with high strength and crack resistance. Background technique [0002] Caulking gypsum is prepared by adding fine hemihydrate gypsum powder and measuring adhesive. It is used for filling of building wall board seams, nail holes, etc. and other parts that need caulking during the construction process. It is indispensable for interior decoration. Package product. [0003] In daily use, cracks often appear between the gaps of floor tiles or wall tiles that are caulked with ordinary caulking gypsum, which affects the appearance, and there is a risk of falling particles. SUMMARY OF THE INVENTION [0004] Aiming at the deficiencies of the prior art, the present invention provides caulking gypsum with high strength and crack resistance. [0005] The present invention realizes and solves the above-mentioned technical problems through the following technical means: [...
