Embodiment 1

[0026] Embodiment 1, superadhesive for wall and floor tile paving is by ordinary Portland cement 31.36% (percentage by weight, the same below), yellow sand (1.25-0.63mm in particle diameter) 45.47%, yellow sand (0.315-0.16mm in particle diameter) 18.81% %, limestone powder 1.254%, sulphoaluminate expansion agent 1.411%, cellulose 0.127%, polyvinyl acetate latex powder 1.568%. The compression-shear bonding strength of the prepared product is 3.8MPa, the water resistance is 3.6MPa, the temperature resistance is 3.5MPa, the freeze-thaw resistance is 3.5MPa, and the cooling time of the product (that is, the time interval when the tensile bonding strength reaches 0.17MPa) It is 25 minutes, the adjustment time is 18 minutes, and the shrinkage rate is 0.05%.

Embodiment 2

[0027] Embodiment 2, superadhesive for wall and floor tile paving is by fly ash cement 33.11%, yellow sand (1.25-0.63mm in particle diameter) 43.05%, yellow sand (0.315-0.16mm in particle diameter) 18.21%, limestone powder 1.987%, sulfur It is formulated with 1.656% aluminate expansion agent, 0.166% cellulose, and 1.821% polyvinyl acetate latex powder. The compression-shear bonding strength of the prepared product is 4.4MPa, the water resistance is 4.2MPa, the temperature resistance is 4.2MPa, the freeze-thaw resistance is 4.3MPa, and the cooling time of the product (that is, the time interval when the tensile bonding strength reaches 0.17MPa) 20min, the adjustment time is 15min, and the shrinkage rate is 0.05%.

Abstract

The invention relates to a wall and floor tile paving ultrastrong adhesive, composed of cement, yellow sand, limestone powder, sulphoaluminate sweller, fibrin and polyvinyl acetate emulsion powder, and it can completely efficiently paving the wall surfaces and top surfaces of buildings, improving the binding strength of ceramic wall tiles and natural and man-made stone materials to the bases by a large margin, and it has high press-cut-binding strength, water resistance, high temperature resistance and good freeze-thaw resistance, and can be cold-placed and has long regulating time, and low shrinkage. It is applied to pasting the decorative materials, such as ceramic wall and floor tiles or marble, granite, man-made stone materials, etc on the surfaces of clay brick, cement mortar, cement and concrete and concrete bricks.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a super-strong adhesive for laying wall and floor tiles. Background technique [0002] Ceramics, as well as natural and artificial stone decoration materials are more and more widely used in the decoration of building facades, interior walls, interior floors, bathrooms and kitchens, swimming pools and reservoirs, etc. Sometimes to prevent water seepage and occurrence Water pollution is also tiled on the bottom of the pool and on the inside of the pool. The quality and durability of pasted veneer materials such as tiles and stones directly depend on the performance and quality of the adhesive used. Since our country has not had special products in this area in the past, and the quality of pasting is not enough, so whether it is outdoor or indoor decoration, cement mortar or cement slurry is generally used when pasting tiles, and the addition accounts for 10...
