Abstract

The invention discloses an environmentally-friendly tile binder, and a preparation method and a use method thereof. The environmentally-friendly tile binder comprises, by weight, 70-85% of an organosilicone emulsion, 10-30% of polymer resin, 1.5-3.5% of a silane coupling agent, 0.1-0.3% of a mildew inhibitor, 0.2% of a wetting agent, 0.5-1.5% of an antifreeze agent and 0.1-0.3% of a defoaming agent. The tile binder has the advantages of excellent adhesion, high mechanical stability, good water and weather resistance, low VOC and no environmental pollution problem, is an environmentally-friendly binder, and can be used in large buildings, railway engineering, road and bridge engineering and pipeline engineering.

Description

technical field [0001] The invention belongs to the field of tile bonding, and in particular relates to an environment-friendly tile adhesive and its preparation method and application method. Background technique [0002] At present, there are various methods for pasting inorganic materials such as ceramic tiles, most of which are tile adhesives that combine common building organic emulsion polymers and inorganic powders. The explanation from the deformation layer theory and the constrained layer theory shows that most organic polymers will shrink during the curing process without the treatment of silane coupling agent, and the interface will generate a large additional stress, which will make the performance worse. This concentrated stress first breaks the bonds of the bonding layer, and the cracks formed destroy the bonded interface. Under the damage of ordinary adhesive layer by the sun's ultraviolet rays and ozone for a long time, the bonding strength gradually weakens...
