Problems solved by technology

[0004] At present, the renovation of old tile walls often adopts the traditional way of removing old wall tiles, because the commonly used interface agent materials have performance shortcomings such as low bonding performance, poor aging resistance, and poor durability; therefore, the renovation of old tile walls has certain advantages. Disadvantages such as long construction period, high cost, and a lot of construction waste

Abstract

The invention discloses a modified geopolymer bonding agent and application method for rapidly renovating an old ceramic tile wall surface thereof, wherein the bonding agent comprises a geopolymer slurry and an emulsion, wherein the geopolymer slurry comprises superfine slag powders, fly ashes, silica fumes, metakaolin, fine sands, admixtures and water; the emulsion comprises water glass, an emulsion and an antimildew agent. The two component slurries are respectively stirred well and then the two component slurries are mixed well to obtain the modified polymer bonding agent for rapidly renovating the old ceramic tile wall surface, and the modified polymer bonding agent can be used for treating the interface of the old ceramic tile wall surface by matching with a corresponding constructionprocess. The modified geopolymer bonding agent has good shear bond strength and tensile adhesive strength, also has good corrosion resistance, and extremely strong durability under various atrociousweather environments. The modified geopolymer bonding agent can be directly used for ceramic tile surface treatment, and is suitable for quickly renovating the old ceramic tile wall surface.

Description

technical field [0001] The invention relates to a geopolymer, in particular to a modified geopolymer interface agent and a method for quickly renovating old ceramic tile walls. Background technique [0002] The interface agent treats the surface of the object, which may be physical adsorption or coating, and often physical and chemical effects. The function is to improve or completely change the physical and technical properties and surface chemical properties of the material surface. In the construction industry, it is commonly used in the base-level interface pretreatment of concrete, aerated concrete, small blocks, lightweight partition walls, brick-concrete walls, putty scraping, tile bonding, masonry back coating, and insulation boards. [0003] There are some tile surface treatment agents on the market. At present, the common interface agents on the market are divided into dry powder type and emulsion type. 1. Dry powder interface agent is a powder composed of inorg...
