Problems solved by technology

[0003] Traditional tile adhesives are generally made of cement, quartz sand, and polymer adhesives as the main ingredients, mixed with various additives, and mixed uniformly by a mixer. They have the characteristics of simple construction, but most of the current tile adhesives Poor resistance to freezing and thawing, the tile adhesive is prone to gaps after being frozen and shrinks, rainwater, etc. seep into the gaps and freeze into ice, and the volume expands, making the gaps larger, and the ice in the gaps melts and then fills them with water. Frozen ice expands, repeated action causes the tile adhesive structure to be destroyed, and the tiles fall off

preparation example 1

[0051] A highly weather-resistant tile adhesive, the preparation steps of modified silica airgel are:

[0052] 1) Sol-gel process: Mix 20kg of tetraethylorthosilicate, 12kg of octyltrimethoxysilane, 80kg of absolute ethanol, and 8kg of deionized water, stir with ultrasonic vibration at 55°C for 30min, and add 30% mass fraction ammonia water to adjust the pH value to 8.5, and continue to ultrasonically oscillate and stir for 2.5 hours to form a mixed solution a of the modified silica wet gel and the solution;

[0053] 2) Aging of the gel: The mixed solution a was left to stand for 45 hours. During the standing process, the solution was continuously discharged slowly, and absolute ethanol was slowly introduced, so that the modified silica wet gel was completely immersed in the absolute ethanol to form Mixture b of modified silica alcohol gel and ethanol;

[0054] 3) Drying of the gel: drying the mixed solution b under supercritical conditions to obtain a hydrophobic modified si...

Abstract

The invention relates to the field of ceramic tile binders, and particularly discloses a high-weatherability ceramic tile binder and a preparation method and a construction method thereof. The ceramictile binder is prepared from the following raw materials in parts by weight: 30-40 parts of ordinary Portland cement, 10-20 parts of modified silicon dioxide aerogel, 55-70 parts of natural fine sand, 1-5 parts of fly ash, 1-3 parts of redispersible latex powder, 0.1-2 parts of cellulose ether and 25-40 parts of water, wherein the modified silicon dioxide aerogel is prepared by a silicon-containing compound participating in an in-situ polymerization process. The ceramic tile binder disclosed by the invention has relatively high weatherability and heat insulation property.

Description

technical field [0001] The present application relates to a tile adhesive, more specifically, it relates to a tile adhesive with high weather resistance and its preparation method and use method. Background technique [0002] Because of its advantages of waterproof, easy to clean, and beautiful appearance, ceramic tiles are widely used in decoration projects on interior and exterior walls, floors and other parts of buildings. The fixing between the tiles and the building is usually by tile adhesive. [0003] Traditional tile adhesives generally use cement, quartz sand, and polymer adhesives as the main ingredients, together with a variety of additives, and are uniformly mixed by a mixer. They have the characteristics of simple construction, but most of the tile adhesives are currently Poor resistance to freezing and thawing, the tile adhesive is prone to gaps after being frozen and shrinks, rainwater, etc. seep into the gaps and freeze into ice, and the volume expands, maki...
