Problems solved by technology

[0004] Emulsion-type tile adhesive, this type of adhesive is generally pressure-sensitive adhesive, if it is applied on the demoulding concrete surface of the aluminum formwork and then tiled, due to the shrinkage of the tile adhesive and the influence of the release oil on the base surface, there will be a whole piece Risk of peeling off
The main reason is that the pressure-sensitive adhesive only forms a layer of very elastic film on the concrete surface, but the bonding strength between this layer of elastic film and the wall is not high, and the shrinkage of the tile adh

Abstract

The invention provides an interface treating agent which comprises, in parts by weight, 20-30 parts of elastic acrylic emulsion, 5-10 parts of aqueous acrylic emulsion having a particle size of 20-50nm, 5-10 parts of a styrene-butadiene emulsion, 2-5 parts of potassium silicate, 10-15 parts of quartz powder, 2-5 parts of active volcanic ash, 0.2-0.8 part of a substrate wetting agent, 0.1-0.2 partof a dispersing agent, 0.1-0.2 part of hydroxypropyl methyl cellulose, 0.1-0.5 part of a thickening agent, 0.2-0.4 part of a defoaming agent and 10-20 parts of water. Compared with the prior art, theinterface treating agent has the advantages that the hollowing probability between the vitrified tile glue and the aluminum formwork demoulding concrete wall is remarkably reduced, and the interfacetreating agent is synchronous with tiling.

Description

technical field [0001] The present invention relates to bonding technology, especially ceramic tile sticking technology. Background technique [0002] The application of large-size vitrified tiles on the wall has become very common, so adhesive products for hollow vitrified tiles have also emerged in an endless stream. In practical application, it does solve the problem of hollowing between vitrified tiles and bonding mortar or tile adhesive. Recently, with the application of more and more aluminum alloy formwork in construction, we found that even if the traditional cement mortar is not used on the plaster-free or thin plastered concrete walls that are demoulded from the aluminum formwork, tile adhesive and tile back adhesive are used instead. When pasting vitrified tiles in combination, there will still be a high probability of hollowing. The hollowing mainly occurs between the tile adhesive and the concrete wall. This is because although the aluminum formwork demoulding...
