Efficient gap filler

Abstract

The invention relates to the field of buildings and particularly relates to an efficient gap filler. The efficient gap filler is prepared from the following substances in parts by weight: 35-45 parts of cement, 15-20 parts of quartz sand, 20-30 parts of washed-out sand, 8-15 parts of pulverized coal ash, 15-25 parts of redispersible organosilicone powder, 5-8 parts of inorganic pigment, 5-8 parts of hydroxyethyl methyl cellulose ether, 0.5-1.5 parts of water reducer, 0.8-1.5 parts of setting retarder, 10-15 parts of zinc chloride, 0.5-1.2 parts of redispersible latex powder, 5-10 parts of heavy calcium carbonate powder, 10-15 parts of polypropylene staple fibers, 1.5-3 parts of hydroxypropyl methylcellulose, 0.8-2.1 parts of mildew preventive, 0.8-2.0 parts of citric acid and 15-30 parts of vitrified micro bubbles. According to the efficient tile gap filler provided by the invention, the low-alkali cement is adopted as a raw material, so that the occurrence of an efforescence phenomenon can be relieved; the added citric acid can be used for effectively inhibiting the occurrence of the efforescence phenomenon; the added water reducer and setting retarder can be used for prolonging the service time of the gap filler, maintaining balance and improving viscosity; and the added vitrified micro bubbles can be used for improving warm-keeping and heat-insulating performance of the gap filler.

Description

technical field [0001] The invention relates to the construction field, in particular to a high-efficiency caulking agent. Background technique [0002] Ceramic tiles have become one of the important building decoration materials in buildings in our country, and are widely used in decoration projects on the interior and exterior walls of buildings and the ground. At present, most of the sealants used in tile facings are mixed and packaged with ordinary cement, building fine sand, and inorganic pigments. When used, they are mixed with water and used as filling materials for tile seams. , [0003] However, this kind of caulking agent will have many disadvantages. Because the adhesive and caulking agent itself contain soluble alkali, salt, etc., when rainwater penetrates into the material, these soluble components will dissolve in water and penetrate into the pores and pores of the brick. If the caulking is not solid, water channels will seep out of the surface, and the CO in...

[0003] However, this kind of caulking agent will have many disadvantages. Because the adhesive and caulking agent itself contain soluble alkali, salt, etc., when rainwater penetrates into the material, these soluble components will dissolve in water and penetrate into the pores and pores of the brick. If the caulking is not solid, water channels will seep out of the surface, and the CO in the air will 2 , acid rain, etc., there will be quality problems and safety hazards such as whitening and alkali return on large areas of tile walls, shrinkage cracks, mildew, and even tile falling off. The insulation effect of the wall is greatly reduced
