Description
Technical Field
The invention relates to the technical field of building materials, in particular to anti-efflorescence tile adhesive and a preparation method thereof.
Background
After the construction of the tile facing external wall heat preservation engineering is carried out for a period of time, white precipitate often appears at the brick joints, namely, the phenomenon of whiskering appears, and whiskering is usually that calcium silicate in silicate cement is hydrated to generate calcium hydroxide which permeates to the surface under capillary pore pressure and generates water-insoluble white precipitated calcium carbonate crystals with carbon dioxide in the air. The whiskering not only affects the appearance of the building, but also is unfavorable for the long-term stability of the external wall system. At present, some treatment methods only can remove white sediment temporarily and reappear after a period of time, so that the best method is to prevent the whiskering.
The main methods for improving the anti-alkali-efflorescence performance of the cement-based material at present are methods for adding pozzolanic raw materials such as metakaolin and the like to react with calcium hydroxide in the material, performing surface waterproof treatment on the material to reduce water transmission, and the like, and the methods have the defects of higher cost and complex process.
Therefore, through research experiments, the applicant controls the introduction of water as an alkaline substance carrier when the tile glue is configured, reduces the precipitation of calcium element soluble ions in the tile glue, reduces the outward migration channel of calcium ions, and can reduce the content of calcium hydroxide by adding active materials to react with calcium hydroxide hydrated by cement so as to improve the anti-whiskering capability.

the powder comprises the following components in percentage by mass:
10-60% of cement, 8-40% of mineral powder, 0.1-10% of active silicon dioxide, 0.1-15% of cellulose ether, 0.1-10% of latex powder, 0.1-6% of water reducer, 0-10% of superfine sodium bicarbonate powder and 0-15% of pigment.
Preferably, the powder comprises the following components in percentage by mass: 20-45% of cement, 10-30% of mineral powder, 0.1-8% of active silicon dioxide, 0.1-15% of cellulose ether, 0.1-10% of latex powder, 0.1-10% of water reducer, 5-8% of superfine sodium bicarbonate powder and 0-15% of pigment.
Preferably, the aggregate is composed of 30-60% and 40-70% by mass of coarse aggregate and fine aggregate.
Preferably, the mineral powder is any one grade of mineral powder in the S75 grade, the S95 grade and the S105 grade.
Preferably, the raw materials of the coarse aggregate and the fine aggregate are all sand for building; the grain size of the fine aggregate is more than 80 meshes and less than 120 meshes, and the grain size of the coarse aggregate is 60-80 meshes.
Preferably, the particle size of the superfine sodium bicarbonate powder is 800-2000 meshes.
Preferably, the cellulose ether is any one of methyl cellulose ether, methyl hydroxyethyl cellulose ether, methyl hydroxypropyl cellulose ether and hydroxyethyl cellulose ether.
The invention also provides a preparation method of the anti-efflorescence tile adhesive, which comprises the following steps:
(a1) Uniformly mixing the raw materials except the water reducer in the powder to obtain a dry material;
(a2) And (3) uniformly mixing the dry material in the step (a 1) with all the rest raw materials, and adding water and stirring to form a mixture.
The other preparation method of the anti-whiskering tile adhesive comprises the following steps:
(b1) Uniformly dispersing part of cellulose ether in water, stirring to a colloid state, adding superfine sodium bicarbonate powder, and uniformly stirring and mixing for later use;
(b2) Uniformly mixing the rest raw materials except the water reducer in the powder to obtain a dry material; and (3) uniformly mixing the dry material, the aggregate, the water reducing agent and the material in the step (b 1), adding water, and stirring to form a mixture.
In any one of the preparation methods, the total amount of the added water is 0.2 to 0.3 times of the sum of the aggregate and the powder.
In summary, due to the adoption of the technical scheme, compared with the anti-whiskering tile adhesive of the existing method, the anti-whiskering tile adhesive has the following beneficial effects:
1. according to the invention, materials such as mineral powder, active silica, emulsion powder and superfine sodium bicarbonate are used in the powder, the mineral powder and the active silica can react with hydration product calcium hydroxide in the cement hydration process to generate gel, so that channels for water to enter and exit are blocked, and meanwhile, calcium hydroxide in a system is consumed, so that migration of calcium ions is reduced, and alkali sources are reduced. The later-stage activity of mineral powder and active silicon dioxide is higher, and the performance indexes of the material in all aspects are improved while the tile glue alkali efflorescence is inhibited.
2. The latex powder and the film forming matter of cellulose ether in the powder can fill a plurality of pores formed in the cement hydration hardening process, the latex powder can play a role in strengthening as an adhesive after being dispersed into a film, the cohesive force of the ceramic tile adhesive mortar is increased, the latex powder and the cellulose ether cannot be dispersed for a second time after being formed into a film, the impermeability is improved together, and the channel for outward migration of calcium ions is reduced. Meanwhile, after the latex powder and cellulose ether are dispersed, part of free calcium ions can be complexed, and after film formation, part of free calcium ions are wrapped, so that the migration quantity of alkali ions is reduced.
3. The superfine sodium bicarbonate powder is also used in the powder, and is wrapped in advance by adopting cellulose ether colloid, so that the superfine sodium bicarbonate powder is temporarily isolated from other materials. After use, the tile glue may cause damage to the film forming structure of the cellulose ether due to changes in the external environment (e.g. excessive humidity, mold growth), reduced impermeability, and outward migration of calcium ions. The superfine sodium bicarbonate powder is slowly decomposed in a wet environment to produce carbon dioxide and carbonate ions, and the carbon dioxide and the carbonate ions penetrate through cellulose ether film forming matters with damaged structures and are diffused, so that calcium carbonate precipitates are formed by combining free calcium ions, and calcium ions are prevented from continuously migrating outwards to form whiskering.

The anti-whiskering tile adhesive disclosed by the invention can inhibit whiskering degree value of the tile adhesive, obvious whiskering does not appear on the surface after the tile adhesive is soaked for a plurality of times, long-time attractive appearance of the surface is effectively ensured, and the formula of the anti-whiskering tile adhesive can effectively inhibit whiskering of the tile adhesive, and meanwhile, various performance index values are improved, so that the anti-whiskering tile adhesive has a good application prospect.
