Non-base-return color ceramic tile joint mixture

Abstract

The invention relates to a safe environment-friendly non-base-return color ceramic tile joint mixture. The safe environment-friendly non-base-return color ceramic tile joint mixture comprises the following components in percentage by weight: 30 to 50 percent of white cement, 40 to 75 percent of filler, 0.03 to 0.30 percent of cellulose ether, 0.50 to 5 percent of adhesive, 0.05 to 0.40 percent of cellulose fiber, 0 to 0.10 percent of chemical fiber, 0 to 0.40 percent of thixotropic agent, 0 to 0.70 percent of water reducing agent, 0 to 0.80 percent of retarder, 0 to 0.4 percent of mildew preventive, 0 to 0.25 percent of water repellent and 0 to 5 percent of ferric oxide series pigment. The safe environment-friendly non-base-return color ceramic tile joint mixture can solve the base return problem of the joint mixture radically and has the advantages of moderate price, safety, environmental friendliness, convenience of production, transportation and storage, wide usable range and the like.

Description

technical field [0001] The invention relates to a safe, environment-friendly and non-alkali-returning colored tile gap filler used for filling gaps between indoor and outdoor tiles of buildings. Background technique [0002] With the development of society, tiles have become one of the most commonly used materials in architectural decoration. In order to avoid hollowing between tiles due to thermal expansion and contraction, a certain gap needs to be reserved between tiles, and the gap needs to be filled with building materials. Initially, the filling material used was mixed on-site by ordinary white Portland cement and heavy calcium or other white fillers in a certain proportion. Due to the shortcomings of the filling material randomly mixed on site, such as high rigidity, insufficient hydration, large water absorption and monotonous color, the filling material often has shortcomings such as cracking, powder falling, and unsightly appearance, and rainwater can easily enter...

AI Technical Summary

Problems solved by technology

Although this material can completely solve the problem of alkali return, it is inconvenient in production, transportation and storage, the width and depth of the gap filled are limited, and the curing speed is relatively slow.
