Flexible tile adhesive

Abstract

The invention relates to a flexible tile adhesive which comprises a component A and a component B. Mass ratio of the component A to the component B is 3:1. The component A is prepared from the following raw materials (by weight): 30-46% of Portland cement, 40-56% of washed-out baked sand, 5-8% of quartz powder, 0.1-0.4% of an antifoaming agent, 1.5-2.2% of cellulose ether, 0.2-0.3% of starch ether, 1.5-3% of redispersible latex powder, 0.4-0.65% of a water reducer and 0.1-0.2% of polypropylene fiber. The component B is prepared from the following raw materials (by weight): 50-75% of an elastic polymer emulsion, 20-45% of water, 0.2-0.5% of a surfactant, 0.3-0.5% of a preservative, 1-3% of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate and 0.5-1% of an ethylene glycol antifreezing agent. The flexible tile adhesive has certain flexibility, is not easy to crack, hollow or fall, has good bleeding resistance, strong scratch resistance and shock resistance, and is easy to operate.

Description

[technical field] [0001] The invention belongs to the technical field of building materials, in particular to a flexible ceramic tile adhesive. [Background technique] [0002] Ceramic tiles are widely used in the construction field of our country because of their advantages of beauty, economy and durability. At the same time, with the continuous improvement of people's quality of life, paving materials such as construction and housing are becoming more and more colorful. The traditional tile adhesive is prepared from Portland cement sand. Due to its large cement content, strong rigidity, and large shrinkage deformation, when faced with larger-sized tiles, the traditional adhesive has no It cannot effectively adapt to the deformation caused by thermal expansion and contraction, and it is easy to cause hollowing and falling off of the adhesive material, which cannot meet the actual engineering needs. Especially for some new paving materials with low water absorption and easy...

Problems solved by technology

The traditional tile adhesive is prepared from Portland cement sand. Due to its large cement content, strong rigidity, and large shrinkage deformation, when faced with larger-sized tiles, the traditional adhesive has no It cannot effectively adapt to the deformation caused by thermal expansion and contraction, and it is easy to cause hollowing and falling off of the adhesive material, which cannot meet the actual engineering needs

Especially for some new paving materials with low water absorption and easy deformation, such as cultural stone, vitrified tiles, antique tiles, etc., the traditional tile adhesives have insufficient adhesion, easy to hang, hollow, and fall off , and too strong steel, insufficient flexibility, easy to crack and other defects
