Problems solved by technology

However, its shortcomings are also obvious. The water resistance is average, and it cannot be used in wet or watery places (such as toilets, pools, etc.). In addition, because of the simple physical bonding, its pulling strength is low, and as time goes by, The coating film is easy to age, harden and become brittle, and the viscosity decreases, so the durability is not long and the service life is short
[0005] Therefore, in the prior art, the two-component tile adhesive has the disadvantages of cumbersome construction and poor tile deformation resistance, and the single-component tile adhesive has the disadvantages of poor water resistance and durability and low pull-out strength.

Abstract

The invention relates to the technical field of chemical construction materials, and particularly relates to preparation of a strong waterproof ceramic tile gum and a using method of the gum. The gumis prepared from styrene-butadiene rubber latex, nano-silica gel, adhesion promoter, packing, silica powder, a thickening agent, cement activator, preservative and water. The ceramic tile gum has super-strong adhesive force of double-component gum and flexible ceramic tile deformation resistance of single-component gum, has excellent waterproofing performance and durability, is simple and quick inconstruction, and can be applied to pavement of various construction environments and various ceramic tiles.

Description

technical field [0001] The invention belongs to the technical field of chemical building materials, and in particular relates to a strong water-resistant ceramic tile back glue and a preparation and use method. Background technique [0002] With the upgrading of consumption, modern families generally use high-end tiles such as polished tiles and vitrified tiles for decoration. This kind of heavy brick with low water absorption rate is used on the wall, even if the national standard JC / T547-2005 "Ceramic Wall and Floor Tile Adhesive" is used. If you use dry powder tile adhesive to paste, it is also prone to hollowing and falling off. Therefore, many manufacturers have developed tile adhesives or adhesives to be used as interface layers to increase the adhesion between tiles and cement mortar, so as to prevent tiles from falling off. [0003] At present, there are mainly two types of tile adhesives. One is a two-component tile adhesive. For example, Chinese invention patent ...
