Description

Technical Field

[0001] The invention relates to the technical field of building materials, in particular to a tile adhesive containing cellulose ether and a production process thereof. Background Art

[0002] Ceramic tiles are a widely used material in architectural decoration, and their installation quality is directly related to the aesthetics and durability of a building. Tile adhesive, a key material in tile installation, plays a crucial role in the construction industry. However, traditional tile adhesives have numerous issues with performance, environmental friendliness, and production processes, making them unable to meet the growing demands of modern architecture.

[0003] From a performance perspective, traditional tile adhesives have limited bond strength. The continuous emergence of new tile materials, such as large-size and ultra-thin tiles, places higher demands on the bonding performance of tile adhesives. Traditional tile adhesives use ordinary cement as the primary binder. The structure and properties of cement hydration products limit the improvement of bond strength. Furthermore, traditional tile adhesives exhibit poor performance stability under varying environmental conditions, such as high temperature, high humidity, or low temperatures. For example, in high-temperature environments, the cement hydration reaction accelerates, causing the tile adhesive to harden too quickly, affecting construction time and bonding effectiveness. In high-humidity environments, long-term moisture erosion can easily weaken the adhesion of the tile adhesive, leading to problems such as tile hollowing and falling.

[0004] In terms of environmental protection, the production process of traditional tile adhesives involves a relatively rough selection and processing of raw materials. The extensive use of natural sand and gravel, which is not finely processed, not only wastes resources but also generates significant dust pollution. Furthermore, traditional tile adhesive formulas often contain hazardous substances such as volatile organic compounds (VOCs) and heavy metals, which are released into the environment during construction and use, posing a threat to indoor air quality and human health.

[0005] Traditional tile adhesive production relies on a simple mixing process, which provides insufficient control over the uniformity of the raw materials. For example, cement, aggregates, and additives are prone to clumping or uneven dispersion during mixing, resulting in unstable tile adhesive quality. Furthermore, traditional production processes lack the means to precisely control product performance, making it impossible to produce tile adhesive products with specific properties tailored to different application scenarios and customer needs.

[0006] While there are some improved tile adhesives on the market, they still have limitations. Some modified products add standard cellulose ethers to improve water retention and workability, but cellulose ethers have limited properties and cannot fundamentally address issues with bond strength and environmental adaptability. Some so-called high-performance tile adhesives use expensive imported raw materials in their production, resulting in high costs and limiting their large-scale application.

[0007] In summary, it is urgent to develop a cellulose ether-containing tile adhesive and its production process that has high bonding strength, good environmental adaptability, environmental protection and advanced production technology, so as to meet the demand of the modern construction industry for high-quality tile paving materials and promote the sustainable development of the construction industry. Summary of the Invention

[0008] (1) Technical problems solved

[0009] In view of the deficiencies of the prior art, the present invention provides a tile adhesive containing cellulose ether and a production process thereof.

[0010] (2) Technical solution

[0011] A tile adhesive containing cellulose ether is composed of the following raw materials in parts by weight:

[0034] (3) Beneficial technical effects

[0035] Compared with the existing technology, the beneficial effects of the present invention are:

[0036] 1. The lattice distortion reinforced cement prepared by a special process has a unique lattice structure that greatly enhances the activity and durability of the cement, providing a strong bonding foundation for tile adhesive. The multi-level pore gradient quartz sand not only optimizes the packing density, but also effectively adsorbs cement hydration products, further improving the bonding strength. The bio-intelligent responsive cellulose ether can intelligently regulate water retention according to environmental changes, ensuring good construction performance and bonding effects under different humidity and temperature conditions. The addition of quantum dot catalytic enhancer Q accelerates the cement hydration reaction, making the tile adhesive cure faster and more densely structured, significantly improving the bonding strength and early strength. According to tests, the tensile bonding strength of the tile adhesive of the present invention is 50%-80% higher than that of traditional products, and the performance stability under different environmental conditions is also greatly improved.

[0037] 2. This invention innovates in raw material selection and processing. The use of plasma-nitrided nano-titanium dioxide and microwave-activated activated metakaolin reduces reliance on natural resources. Environmentally friendly measures introduced during the production process, such as the introduction of trace amounts of ozone during mixing in a high-speed mixer to promote fusion, avoid the use of harmful chemical additives. Furthermore, the product contains no harmful volatile organic compounds or heavy metals, truly achieving environmental protection and contributing to a healthy indoor environment.

[0038] 3. The production process of this invention utilizes a series of advanced technologies, such as oxygen-enriched combustion in the high-temperature calcining furnace to improve calcination efficiency, ultrasonic assistance and a special paddle structure in the high-speed mixer to ensure uniform raw material mixing, and the self-cleaning nanomaterials and vibration mechanism in the pneumatic conveying system to reduce material residue. These technologies not only improve production efficiency but also ensure stable and consistent product quality. They enable precise control of product performance according to specific needs, reduce production costs, and have promising market application prospects, significantly promoting the upgrading of tile adhesive production processes.
