Abstract

The invention belongs to the field of building materials, and particularly relates to a low alkaline tile joint mixture. The low alkaline tile joint mixture is composed of the following components in mass percent: 20%-50% of cement, 20%-50% of silica sand, 0.01%-35% of coarse whiting powder, 0.01%-1.0% of redispersible powder, 0.01%-0.2% of organic silicon powder, 0.01%-0.5% of cellulose ether, 0.01%-8% of pigment, 0.01%-0.1% of retarder, and 0.01%-0.05% of citric acid. The low alkaline tile joint mixture is water-tolerant, can not crack, has good ageing-resistant performance and excellent flexibility, is firm when being bonded with a base layer, is quick-drying and quick-hardening, and can avoid the happening of the situation of saltpetering after the construction in the humid environment or cold weather.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a low-alkaline ceramic tile caulking agent. Background technique [0002] Today, with the rapid development of the construction industry, adhesives are widely used in the pasting of bricks in construction, and the pasting of bricks needs to be combined with caulking agents. Since the adhesive and caulk itself contain soluble alkali, salt, etc., when rainwater seeps into the material, these soluble components will dissolve in the water, penetrate into the capillary pores of the brick and the gaps where the caulking is not solid, and form water channels seeping out of the surface, and then combine with CO2 in the air, acid rain, etc. contact to produce insoluble white substances, namely pan-alkali. [0003] Pan-alkali will affect the appearance of the building and give people a feeling of insecurity; pan-alkaline will affect the quality of the painting, and it is easy...
