AI Technical Summary

Problems solved by technology

The above products are all water-based products, which have the following disadvantages: 1. Poor water resistance
2. Low bonding strength: The above-mentioned types of tile adhesives play a bonding role mainly because the emulsion forms a film, but the adhesion of these emulsions to tiles and cement mortar is not good, although it seems to have good adhesion , but when combined with ceramic tiles and cement mortar, its actual bond strength will be greatly reduced

Abstract

The invention provides a two-component ceramic tile back adhesive as well as a use method and a preparation method thereof, and belongs to the technical field of adhesives. The two-component ceramic tile back adhesive comprises a component A and a component B, wherein the component A comprises the following components in parts by weight: 45-65 parts of epoxy resin, 3-8 parts of a diluent, 1-3 parts of hydrophobic fumed silica, 0.1-0.3 part of a polyamide rheological additive, 15-25 parts of filler and 15-30 parts of dimethyl ether; and the component B comprises the following components in parts by weight: 40-60 parts of a curing agent, 5-10 parts of a diluent, 1-3 parts of hydrophobic fumed silica, 0.5-1 part of a polyamide rheological additive, 15-25 parts of filler and 15-30 parts of dimethyl ether. The two-component ceramic tile back adhesive provided by the invention is high in adhesive strength and good in aging resistance, and can effectively solve the problems of infirm adhesion, hollowing and falling of vitrified tiles.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a two-component back adhesive for ceramic tiles and its use and preparation methods. Background technique [0002] Tile adhesive is an auxiliary material applied to tile laying. With the development of technology and the improvement of decoration quality, most of the tiles used in home decoration are vitrified tiles with extremely low water absorption, which makes it difficult to stick the tiles firmly with traditional cement mortar used in decoration , Tile adhesive came into being. [0003] At present, the tile adhesives on the market are mainly divided into the following types: 1. Two-component tile adhesives: The tile adhesives are mainly composed of styrene-butadiene emulsion and cement. 2. Ready-to-use tile adhesive: mainly composed of acrylic emulsion and quartz sand. 3. Waiting type tile adhesive: mainly composed of acrylic emulsion with low glass transit...
