Description

Technical Field

[0001] This invention relates to the field of building decoration materials technology, and more specifically, to a high-bonding-strength, water-resistant gypsum-based tile adhesive. Background Technology

[0002] With the development of the building decoration industry, ceramic tiles, as a common decorative material, are widely used in floor and wall paving. However, traditional gypsum-based tile adhesives have limitations in terms of bonding strength and water resistance, especially in humid environments such as bathrooms and kitchens. Moisture intrusion can affect their bonding effect and service life, ultimately leading to hollowing and detachment of tiles during use. Therefore, developing a high-bonding-strength, water-resistant tile adhesive is of great significance for overcoming the shortcomings of traditional tile adhesives, extending the service life of tiles, and improving the quality of building projects. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-bonding-strength, water-resistant gypsum-based tile adhesive, which has the characteristics of water resistance, high bonding strength, crack resistance, freeze-thaw resistance, aging resistance, and fast setting time, thus helping to improve construction efficiency and building quality.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-bonding-strength, water-resistant gypsum-based tile adhesive, comprising the following raw materials in parts by weight: 60-70 parts by weight of gypsum, 10-20 parts by weight of heavy calcium carbonate, 0.4-1 parts by weight of cellulose ether, 2-5 parts by weight of latex powder, 2-5 parts by weight of reinforcing agent, 16-30 parts by weight of aggregate, 1-3 parts by weight of toughening agent, and 1-3 parts by weight of waterproofing agent; wherein the toughening agent is a hyperbranched polyester, and the waterproofing agent is an organic waterproofing agent containing active silicon.

[0006] The present invention is further configured such that the latex powder is a terpolymer of vinyl chloride, ethylene and vinyl laurate.

[0007] The present invention is further configured such that the latex powder is ZW-9032H latex powder.

[0008] The present invention is further configured such that the reinforcing agent is at least one of basalt fiber, carbon fiber, and plant fiber.

[0009] The present invention is further configured such that the reinforcing agent is Artemisia annua fiber.

[0010] The present invention is further configured such that the toughening agent is epoxy resin toughening agent CYH-277.

[0011] The present invention is further configured such that the waterproofing agent is a gypsum-based reactive waterproofing agent SL-17.

[0012] The present invention is further configured such that the aggregate is natural sand.

[0013] The present invention is further configured such that the tile adhesive is made from the following raw materials in parts by weight: 60 parts by weight of gypsum, 11.2 parts by weight of heavy calcium carbonate, 0.8 parts by weight of hydroxypropyl methylcellulose, 4 parts by weight of latex powder, 3 parts by weight of Artemisia argyi fiber, 16.5 parts by weight of natural sand, 2 parts by weight of epoxy resin toughening agent CYH-277, and 2.5 parts by weight of gypsum-based reactive waterproofing agent SL-17.

[0014] In summary, the present invention has the following beneficial effects:

[0015] A gypsum-based tile adhesive with excellent water resistance and high bonding strength was prepared through formula improvement and optimization, while also exhibiting good freeze-thaw resistance and aging resistance. In particular, the addition of Artemisia argyi fiber, epoxy resin toughening agent CYH-277, and gypsum-based reactive waterproofing agent SL-17 as modifiers further enhances the water resistance and bonding strength of the tile adhesive through their synergistic effect. This invention provides convenient application and rapid setting, solving the problems of poor water resistance, easy cracking, and poor impact resistance of gypsum-based materials. It eliminates cracking and hollowing phenomena, improves construction efficiency, and is more suitable for tile laying in home decoration, commercial buildings, and large-scale projects.
