Two-component ceramic tile adhesive

Abstract

The invention discloses a two-component ceramic tile adhesive composed of a powder adhesive and a back adhesive; the powder adhesive is composed of the raw materials in parts by mass: 200-400 kg of cellulose ether, 30-70 kg of starch ether, 50-150 kg of calcium formate, 60-130 kg of a water reducing agent and 30-70 kg of a water repellent; the back adhesive is composed of the raw materials in parts by mass: 250-450 kg of an acrylic emulsion, 30-70 kg of water, 0.8-1.6 kg of a defoaming agent, 0.3-0.7 kg of a preservative, and a thickening agent, wherein the part amount of the thickening agent is used for adjusting the viscosity of the back adhesive to 5000-50000 MPa*s. The powder adhesive does not contain cement and quartz sand, and saves a lot of transportation and carrying costs; the back adhesive is mainly used for cooperating with heavy tiles, marble, vitrified tiles and other tiles with relatively low water absorption rate for back surface treatment, makes the tiles more fitted with the powder adhesive, and avoids generation of hollowing and other phenomena.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a two-component ceramic tile adhesive. Background technique [0002] At present, most of the tile adhesives on the market are produced by mixing raw materials such as cement, quartz sand, cellulose ether, and rubber powder through a dry powder mixer. In the existing formula of ceramic tile adhesive, the sum of the mass of cement and quartz sand accounts for 95% of the entire adhesive mass, and the content of ingredients that really play a role in bonding only accounts for 5% of the entire adhesive mass. The proportioning method greatly increases the transportation cost and handling cost of the ceramic tile adhesive, causing unnecessary waste. Contents of the invention [0003] The object of the present invention is to provide a two-component ceramic tile adhesive with low transportation cost and which can effectively prevent ceramic tile hollowing. [0004] To achieve the a...
