Gap filler

Abstract

The invention discloses a gap filler which comprises the following components in parts by weight: 40-70 parts of quartz sand, 20-30 parts of sulfoaluminate cement, 3-10 parts of antioxidant, 1-3 parts of adhesive, 1-2 parts of cellulose ether, 1-3 parts of mold preventive, 5-10 parts of inorganic aluminum salt waterproofing agent, 1-3 parts of organosilicon leveling agent and 0.5-1 part of lignin fiber. The gap filler disclosed by the invention has the advantages of favorable water resistance, favorable re-alkali resistance, mold resistance and oxidation resistance, is easy and safe for construction, and thus, is a favorable gap filler for spreading and attaching ceramic tiles.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a caulking agent for laying ceramic tiles. Background technique [0002] The laying of ceramic tiles has become a common decoration in daily life. From home to hotels and other public places, from the ground to the wall, the decorative effect brought by ceramic tiles cannot be underestimated. However, in the process of laying and laying, bricks and bricks The joints between the blocks need to be specially treated. At present, the commonly used joint sealant is cement mortar, which has low adhesion and is prone to cracking after curing, thereby absorbing water. If it encounters thermal expansion and contraction, it will Cause the tiles to burst, or too much water seeps in and the adhesion between the tiles and the wall is not strong enough to fall off. However, there are often Portland cement components in the joint filler, and there will be varying degrees of alkali reversion a...
