Problems solved by technology

Fast-hardening tile adhesives set and harden quickly, and the operating time is shorter than that of ordinary tile adhesives. However, domestic workers are not skilled enough in laying tiles with the thin paste method, and the construction efficiency is low. Therefore, fast-hardening tile adhesives are required to have sufficient operating time.

Embodiment 1

[0020] 24 parts of Portland cement, 8 parts of high alumina cement, 8 parts of anhydrite, 58 parts of quartz sand, 2 parts of dispersible polymer powder, 0.2 parts of water retention agent, 0.3 parts of lithium carbonate, 0.02 parts of tartaric acid, 0.02 parts of sodium gluconate share.

Embodiment 2

[0022] 10 parts of Portland cement, 20 parts of high alumina cement, 10 parts of anhydrite, 58 parts of quartz sand, 2 parts of redispersible polymer powder, 0.2 parts of water retention agent, 0.2 parts of lithium carbonate, 0.03 parts of tartaric acid, 0.03 parts of sodium gluconate share.

[0023] The tile adhesives prepared in Examples 1 and 2 have a 6h tensile adhesive strength of up to 0.5MPa, and an operable time of not less than 40min. The tile adhesives prepared in Examples 1 and 2 have an original tensile strength of adhesive and adhesive strength of about 1.5-2.0 MPa after airing for 20 minutes, and an adhesive strength of about 1.0-1.5 MPa after thermal aging. The strength is about 0.8-1.2MPa, which exceeds the 0.5MPa specified in the JC / T 547-2017 "Ceramic Tile Adhesive" standard, and has excellent construction performance and performance.

Abstract

The invention discloses a high-performance rapid-hardening ceramic tile adhesive which is prepared from the following components in parts by weight: 30- 40 parts of cement, 8-10 parts of gypsum, 50-65parts of quartz sand, 2-3 parts of re-dispersible latex powder, 0.2-0.3 part of water retaining agent, 0.15-0.3 part of early strength agent and 0.04-0.09 part of retarder. Compared with the prior art, the high-performance rapid-hardening ceramic tile adhesive disclosed by the invention has the characteristics of rapid hardening and high strength and can be set and hardened rapidly; through 6 hours of stretching, the adhesive strength can reach the industrial standard 0.5MPa, and the operable time is not less than 40min, enough for operation; meanwhile, the high-performance rapid-hardening ceramic tile adhesive is green and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a high-performance fast-hardening tile adhesive with sufficient operable time. Background technique [0002] Tile is a widely used decorative building material. With the advancement of urbanization, ceramic tiles are gradually developing in the direction of large size and low water absorption, but the development of ceramic tile paving technology and supporting tile adhesives has not been synchronized with it, resulting in many quality problems in domestic ceramic tile paving. At the same time, the continuous increase in labor costs and the requirements of construction units for rapid construction have also increased the demand for high-performance fast-hardening tile adhesives. Fast-hardening tile adhesives set and harden quickly, and the operating time is shorter than that of general tile adhesives. However, domestic workers are not skilled enough in lay...
