Abstract
Description
Technical Field
[0001] This invention relates to the field of lightweight building materials technology, and in particular to a durable sound-insulating ceramic tile adhesive and its preparation method. Background Technology
[0002] As living standards improve, people are demanding higher levels of sound insulation in their living environments. Traditional building floors are often tiled. To achieve ideal sound insulation from impacts, sound-absorbing coatings or mortar are typically sprayed or applied to the concrete slab before the tiles are laid with cement mortar. This practice not only significantly reduces the actual floor height but also substantially increases building and renovation costs.
[0003] Tile adhesive is a modern building material widely used for bonding ceramic tiles, facing bricks, floor tiles, and other decorative materials. Traditional polymer-modified cement-based tile adhesives require a large amount per unit area, significantly increasing the building's load. Therefore, it is necessary to address the hollowing phenomenon caused by thick-layer tile bonding and to minimize the building's load.
[0004] Existing technologies often involve adding a large amount of lightweight filler to lightweight tile adhesives. While this can reduce the building load, the bonding strength is generally low, making it easier for tiles to become hollow or fall off after installation, which seriously affects safety and aesthetics. At the same time, its sound insulation and mechanical strength are not ideal, making it difficult to meet the requirements of modern buildings for sound insulation and durability.
[0005] To address the aforementioned issues, there is an urgent need to develop a lightweight tile adhesive that can significantly improve bonding strength, sound insulation, and mechanical strength while maintaining its lightweight properties, making it a promising area for research. Summary of the Invention
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a durable sound-insulating ceramic tile adhesive and its preparation method.
[0007] A durable sound-insulating ceramic tile adhesive, the raw materials of which, by weight, include: 50-80 parts of sulfoaluminate cement, 10-30 parts of gypsum, 5-15 parts of fly ash, 5-10 parts of calcium oxide, 1-2 parts of calcium formate, 1-2 parts of potassium hydroxide, 1-5 parts of dispersible latex powder, 1-2 parts of wood fiber, 1-2 parts of polypropylene fiber, 5-15 parts of loaded bamboo powder, 5-12.8 parts of sodium silicate, and 0.1-1 parts of water-retaining agent.
[0008] Preferably, the sulfoaluminate cement is of type L-SAC42.5.
[0009] Preferably, the gypsum is β-type hemihydrate gypsum.
[0010] Preferably, the loaded bamboo powder is prepared by the following method: bamboo powder is added to hydrochloric acid and ultrasonically treated for 1-2 hours, filtered, washed, vacuum dried, and pulverized; then added to a Tris-HCl buffer solution with a pH of 8-9, dopamine is added, ultrasonically vibrated under stirring for 2-4 hours, filtered, and vacuum dried.
[0011] More preferably, the mass ratio of bamboo powder to dopamine is 10-20:1-5.
[0012] More preferably, the frequency of ultrasonic treatment in hydrochloric acid is 70-80 kHz.
[0013] More preferably, the frequency of the ultrasonic oscillation is 40-70 kHz.
[0014] The preparation method of the above-mentioned durable sound-insulating tile adhesive includes the following steps:
[0015] S1. Add the loaded bamboo powder to the sodium silicate solution and stir for 10-20 min. Pass excess carbon dioxide into the solution and keep it at 80-90℃ for 2-5 h. Filter, wash, vacuum dry, sinter at 400-500℃ for 1-2 h under argon protection, cool, and pulverize to obtain porous bamboo powder.
[0016] S2. Mix sulfoaluminate cement, gypsum, porous bamboo powder, fly ash, calcium oxide, calcium formate, potassium hydroxide, water-retaining agent, dispersible latex powder, wood fiber, and polypropylene fiber evenly.
[0017] Preferably, in S1, the flow rate of carbon dioxide is 1-1.2 L / min.
[0018] The above-mentioned durable sound-insulating tile adhesive is used by mixing it with water at a mass ratio of 1:1-3, and then applying it to the tile bonding surface or the base surface of the tile to be laid, with a thickness of 4-8mm.
[0019] Beneficial effects:
[0020] This invention involves acid washing bamboo powder with hydrochloric acid to form a porous structure, followed by an oxidative polymerization of polydopamine on the surface. This process enhances the interfacial affinity of sodium silicate solution through self-polymerization and cross-linking. Subsequently, an excess of carbon dioxide is introduced, transforming the sodium silicate into gel-like silicic acid. This gel is then sintered at high temperature to form a uniformly distributed silica deposition layer, resulting in a multi-porous structure. This not only preserves the lightweight properties of bamboo powder but also effectively blocks sound wave propagation through the porous structure, significantly improving sound insulation performance.
[0021] This invention uses sulfoaluminate cement, porous bamboo powder, and fly ash as a compound. The porous properties of bamboo powder are used to absorb sound energy, and fly ash reacts with potassium hydroxide to generate active cementitious substances. Wood fibers and polypropylene fibers effectively enhance the vibration damping and sound absorption function of the matrix. The fiber network disperses stress, reduces sound wave reflection, and significantly improves the overall sound insulation effect.
[0022] The lightweight tile adhesive obtained by this invention not only has good sound insulation effect, but also achieves excellent sound insulation performance even when applied in a thin layer of 4-8mm. At the same time, the tile adhesive has high bonding strength and high mechanical strength, and the preparation method is simple and the construction process is convenient, making it suitable for industrial-scale production.

[0077] The reasons for the above results are as follows: On the one hand, the present invention forms a porous structure by acid washing bamboo powder with hydrochloric acid, and oxidizes and polymerizes a polydopamine layer on its surface, which enhances the adsorption capacity of sodium silicate solution through self-polymerization and cross-linking; subsequently, after passing in excess carbon dioxide, sodium silicate is converted into gel-like silicic acid, and then sintered at high temperature to form a uniformly distributed silica deposition layer, so that the product has a multi-porous structure, which not only retains the lightweight characteristics of bamboo powder, but also effectively blocks the propagation of sound waves through the porous structure, significantly improving the sound insulation performance; on the other hand, sulfoaluminate cement is compounded with porous bamboo powder and fly ash, which utilizes the porous characteristics of bamboo powder to adsorb sound energy, and reacts with fly ash and potassium hydroxide to generate active cementitious substances, while wood fiber and polypropylene fiber effectively enhance the vibration damping and sound absorption function of the matrix, disperse stress through the fiber network, reduce sound wave reflection, and significantly improve the overall sound insulation effect.
