Description

Technical Field

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

[0002] With the development of the building decoration industry, ceramic tiles, as a common decorative material, are widely used in the field of 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, water intrusion will affect its bonding effect and service life, and eventually lead to hollowing and falling of tiles during use. Therefore, the development of a high-bonding strength and water-resistant tile adhesive is of great significance to solve the shortcomings of traditional tile adhesives, extend the service life of tiles, and improve the quality of construction projects. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a high bonding strength and water-resistant gypsum-based tile adhesive, which has the characteristics of water resistance, high bonding strength, crack resistance, freeze-thaw resistance, aging resistance, fast setting time, etc., which helps to improve construction efficiency and the quality of construction projects.

[0004] In order to achieve the above object, the present invention adopts the following technical solution:

[0005] A high-bonding-strength water-resistant gypsum-based tile adhesive is prepared from the following raw materials in parts by mass: 60-70 parts by mass of gypsum, 10-20 parts by mass of heavy calcium carbonate, 0.4-1 parts by mass of cellulose ether, 2-5 parts by mass of latex powder, 2-5 parts by mass of reinforcing agent, 16-30 parts by mass of aggregate, 1-3 parts by mass of toughening agent, and 1-3 parts by mass of waterproofing agent; 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 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 that the tile adhesive is made of the following raw materials in parts by mass: 60 parts by mass of gypsum, 11.2 parts by mass of heavy calcium carbonate, 0.8 parts by mass of hydroxypropyl methylcellulose, 4 parts by mass of latex powder, 3 parts by mass of artemisia fiber, 16.5 parts by mass of natural sand, 2 parts by mass of epoxy resin toughener CYH-277, and 2.5 parts by mass 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 good water resistance and high bonding strength is prepared by improving and optimizing the formula, and has good freeze-thaw resistance and aging resistance; in particular, the tile adhesive is prepared by adding artemisia fiber, epoxy resin toughening agent CYH-277, and gypsum-based reactive waterproofing agent SL-17 as a modified material, and the synergistic effect between the three is utilized to further improve the water resistance and bonding strength of the tile adhesive. The tile adhesive of the present invention is convenient to construct and has a fast setting time, solves the problems of poor water resistance, easy cracking, and poor impact resistance of gypsum-based materials, eliminates the occurrence of cracking and hollowing, improves construction efficiency, and is more suitable for home decoration, commercial construction, and tile laying in large-scale projects.
