preparation example Construction

[0040] Yet another embodiment of the present invention provides a kind of preparation method of above-mentioned tile glue, comprises the following steps:

[0041] Step 1: Preparation of powdery materials: take the Yellow River sediment, dry fine sand and silt and transport them to the feeder and pulverizer in turn, put them in the dryer for drying, and then sieve to obtain powdery materials of 200-300 mesh;

[0042] Step 2: Preparation of rosin saponification: Take rosin, sodium hydroxide and water and put them into a reaction kettle and heat at 160-190°C for 20-40 minutes to obtain a brown transparent paste. Put the paste into a vacuum of 93.3-98.6KPa. Dry the body in a vacuum oven at a temperature of 60-80°C for 5-7 hours, and then pulverize to obtain saponified rosin;

[0043] Step 3: Preparation of tile adhesive: Take the cement and the powdered material obtained in Step 1 and add them to the mixer, stir in a dry state for 1 to 2 minutes, then add water-soluble silicate, red...

Abstract

The invention relates to the technical field of building materials, in particular to an adhesive for tiles and a preparation method of the adhesive. The adhesive comprises, by weight, 25-38 parts of Yellow River sediments, 20-35 parts of dry fine sand, 10-25 parts of sludge, 12-20 parts of cement, 2-10 parts of rosin saponified products, 1-5 parts of water-soluble silicate, 1-5 parts of re-dispersible latex powder and 0.2-2 parts of micro-expansion agents. The adhesive for the tiles has high bonding strength, water resistance, corrosion resistance and thermal aging resistance (70 DEC C), and can withstand tests in which wet and dry conditions alternate or freezing and thawing conditions alternate, completely solving the problems of whiskering, hollowing and peeling of the tiles.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a tile adhesive and a preparation method thereof. Background technique [0002] Tile glue, also known as ceramic tile adhesive, is mainly used to paste decorative materials such as ceramic tiles, facing tiles, and floor tiles. Its main features are high bonding strength, water resistance, freeze-thaw resistance, good aging resistance and convenient construction. It is a very ideal bonding material. Tile adhesives contain a variety of additives, specifically the functionality of tile adhesives. Generally, cellulose ethers that provide water retention and thickening effects are added to tile adhesives, as well as latex powders that increase the adhesion of tile adhesives. The most common latex powders are vinyl acetate / vinyl ester copolymers, vinyl laurate / ethylene / vinyl chloride Copolymer, acrylic and other additives, the addition of latex powder can greatly increase ...
