Anti-efflorescence high-strength tile grout

Abstract

The invention discloses anti-efflorescence high-strength tile grout, which comprises a component A and a component B according to a mass ratio of (0-0.5):1. The component A is prepared from, by weight, 50-85% of epoxy emulsion, 0.1-0.50% of an antifoaming agent, 0.1-0.5% of preservatives and 15-49% of water. The component B is prepared from, by weight, 30-40% of aluminate cement, 10-20% of gypsum,15-30% of quartz sand, 15-30% of calcium carbonate powder, 0.2-0.5% of cellulose ether, 0.02-0.10% of a retarder and 0.1-1.0% of a water repellent agent. The anti-efflorescence high-strength tile grout which adopts aluminate cement is free of calcium hydroxide and avoids the problem of efflorescence, and the anti-efflorescence high-strength tile grout is prepared from compounding of epoxy emulsion, aluminate cement, gypsum, quartz sand and the like and has advantages of high strength, low water absorption capacity, freeness of efflorescence, excellent stain resistance and high abrasion resistance.

Description

technical field [0001] The invention relates to a waterproof building material, in particular to a high-strength anti-efflorescence ceramic tile sealant. Background technique [0002] In modern buildings, ceramic tiles have become the main building materials and are widely used in the decoration of the interior and exterior walls and floors of buildings. Reserve a certain gap, which needs to be filled with a caulking agent, especially for the brick decoration system on the exterior wall of the building, the quality of the caulking agent will directly affect the decorative effect of the exterior wall. [0003] At present, commonly used caulking agents 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 places where the caulking is not solid, form water channels seeping out of the surface, and then contact with the air C0 in 2 , acid rain, etc.,...

AI Technical Summary

Problems solved by technology

Pan-alkali will not only affect the quality of the painting, but it is prone to delamination, leading to failure of decoration, resulting in structural cracking, abnormal expansion and cracking of the structure, affecting the appearance of the building, and it is also easy to cause skin diseases and respiratory diseases, and may even induce cancer

In addition, the existing fillers between tiles and tile gaps also have problems such as high water absorption, stain resistance, and poor wear resistance.
