Environment-friendly colorful tile joint mixture and preparation method thereof

Abstract

The invention discloses an environment-friendly colorful tile joint mixture. The environment-friendly colorful tile joint mixture is characterized by comprising the following components in percentage by weight: 35%-40% of white cement, 40.73%-47.75% of waste porcelain powder, 0-15% of quartz powder, 0-10% of titanium dioxide, 1%-1.5% of re-dispersible emulsion powder, 0.1% of water repellent, 0.15% of water-retaining agent, 0.4% of lignin fiber, 0.1%-0.25% of water reducing agent and 0-2% of pigment. The invention further discloses a preparation method of the environment-friendly colorful tile joint mixture. The consumption of quartz sand and heavy calcium powder is reduced by using the waste porcelain powder as the joint mixture filler; the early strength of the joint mixture is improved by virtue of early strength function of the white cement, so that the construction process requirements are satisfied. The waste porcelain powder is sintered at a high temperature, so that the physical and chemical performances are stable, the volume is stable, and the expansion-shrinkage coefficient is close to that of the tile; the material with the same expansion-shrinkage coefficient is used as the filler, so that the possibility that the tile joint mixture generates cracks can be further reduced.

Description

technical field [0001] The invention relates to a ceramic tile caulking agent used in construction engineering, in particular to an environment-friendly colored ceramic tile caulking agent and a preparation method thereof. Background technique [0002] In modern buildings, tiles have become the main building materials and are widely used in the decoration of the interior and exterior walls and floors of buildings. In order to avoid hollowing between tiles due to thermal expansion and contraction, there must Leave a gap that needs to be filled with tile grout. The tile grout should have an expansion coefficient close to that of the tiles and a certain degree of flexibility, which can expand and contract with the tiles to avoid cracks. The main components of tile grout are cementitious materials, fillers and additives. The cementitious materials endow the grout with adhesion, the additives endow the grout with good workability, flexibility and other functions, and the fillers...
