Gap filler

Abstract

The invention discloses a gap filler which comprises the following components in parts by weight: 40-70 parts of quartz sand, 8-12 parts of calcium carbonate, 20-30 parts of sulfoaluminate cement, 3-10 parts of antioxidant, 1-3 parts of adhesive, 0.2-0.6 part of cellulose ether, 1-3 parts of mold preventive and 5-10 parts of inorganic aluminum salt waterproofing agent. The quartz sand used as the main body component of the gap filler lowers the cost of the gap filler; the mold preventive is mainly used for preventing mold due to water absorption; the addition of the inorganic aluminum salt waterproofing agent can perform the waterproofing function after the gap filler is cured; and the sulfoaluminate cement can prevent the re-alkali phenomenon after use for some time, accelerate the hydration of cement and enhance the strength. The gap filler 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 joint sealant for tile paving. Background technique [0002] The paving of tiles has become a common decoration in daily life. From homes to hotels and other public places, from the ground to the wall, the decorative effect brought by the tiles cannot be underestimated. However, in the process of paving, bricks and bricks The caulking between blocks needs special treatment. At present, the commonly used caulking agent is cement mortar. This kind of caulking agent has low adhesion and is prone to cracking after curing, thereby absorbing moisture. If it encounters thermal expansion and contraction, it will Causes the tile to burst, or too much water infiltrates, causing the tile and the wall to not adhere firmly and fall off.

[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, thus 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

Sometimes cellulose ether is added to the sealant to retain water, but the amount of cellulose ether added needs to be strictly controlled. If too much is added, it will be too viscous, and if too little is added, the water in the sealant will evaporate too quickly. The sealant is not strong enough
