Description

Technical Field

[0001] The invention relates to the technical field of tile adhesive, and in particular to a super-weather-resistant rock plate diamond steel sand two-component tile adhesive and a preparation method thereof. Background Art

[0002] In the field of building decoration, ceramic tiles are a widely used decorative material, and their pasting and fixing technology has always been valued. Traditional ceramic tile pasting mainly relies on cement mortar, but with the improvement of ceramic tile materials, such as vitrified tiles with low water absorption, polished tiles, etc., traditional pasting materials can no longer meet the bonding requirements, resulting in frequent hollowing and falling of ceramic tiles. In order to solve this problem, ceramic tile adhesive came into being, which effectively reduces the risk of hollowing and falling by improving the bonding strength between ceramic tiles and adhesive materials.

[0003] However, there are some shortcomings in the tile adhesive of the prior art. First, the weather resistance is not satisfactory. With the passage of time and the continuous influence of the natural environment, including long-term sun exposure, rain, high and low temperature changes, and humidity fluctuations, the existing tile adhesive is prone to aging, brittleness, cracking, etc. This will not only destroy the overall beauty of the building, but more seriously may cause the tiles to fall off, posing a potential threat to personal and property safety. For example, in the outdoors or in areas with harsh climatic conditions, the existing adhesives often cannot withstand long-term tests and cannot provide stable and lasting adhesion for tiles.

[0004] Secondly, there is a lot of room for improvement in bonding strength. The existing adhesive has limited adaptability to different types of tiles and complex base surfaces. On some special substrates, such as new tiles with low water absorption or smoother base surfaces, the adhesive is not strong enough to bond with the tiles and base, which can easily lead to hollowing. Moreover, after a period of time, due to the influence of various factors, the bonding strength will gradually decrease, which cannot meet the requirements of long-term stable bonding of tiles.

[0005] Furthermore, chemical corrosion resistance needs to be improved. In actual use environments, tiles may come into contact with chemicals such as acids, alkalis, and salts, such as acid rain, detergents, and chemical seepage from building materials. Existing adhesives are easily corroded in these environments, resulting in reduced performance and shortened service life. Especially in some industrial environments or special places, higher chemical corrosion resistance is required for adhesives, but existing products often fail to meet this requirement.

[0006] In addition, there are also problems in the preparation process. The existing adhesive often has uneven stirring during the stirring process, resulting in uneven distribution of ingredients, which affects the performance stability of the adhesive. At the same time, there are also differences in the compatibility between different ingredients, which may cause stratification and precipitation during use, further reducing the quality of the adhesive. Moreover, the existing preparation process does not accurately control parameters such as temperature and rotation speed, which will also affect the final performance of the adhesive. Summary of the invention

[0079] Test Example 1- Bond Strength Test

[0080] (1) Tensile bond strength test: According to the relevant standard (JC / T547-2017 Ceramic Tile Adhesive), the ceramic tile is adhered to the ceramic plate with the adhesive backing. After curing for 28 days at a temperature of 23°C ± 2°C and a relative humidity of 50% ± 5%, a tensile testing machine is used to apply a tensile force perpendicular to the bonding surface at a speed of 5 mm / min until the ceramic tile is separated from the substrate. The maximum tensile force value is recorded and the tensile bond strength is calculated.

[0081] (3) Shear bond strength test: Use a shear test device to bond the tile to the substrate with the adhesive, and then apply a shear force parallel to the bonding surface. This simulates the ability of the adhesive to resist horizontal external forces (horizontal forces generated by wall deformation) on the tile. During the test, the maximum force value at shear failure is recorded, and the shear bond strength is calculated to provide data support for the adhesive's ability to resist shear forces in actual applications.

[0085] (1) Artificial climate aging test: Use an artificial climate aging chamber to simulate the natural environment's light, temperature changes, humidity changes, rainfall and other factors. Place the test piece coated with adhesive and pasted with tiles in the aging chamber for 2000 hours. After the aging cycle, observe whether the tiles have fallen off or hollowed out, and conduct a bonding strength test.

[0089] Test Example 3-Weather Resistance Test

[0090] (1) Acid and alkali resistance test:

[0091] The test pieces coated with the adhesives of Examples 1-5 and Comparative Examples 1-3 and pasted with tiles were immersed in an acidic solution of pH=2 (simulating an acid rain environment) and an alkaline solution of pH=13 (simulating an alkaline building material exudate environment). After immersion for 28 days, the test pieces were taken out, the bonding of the tiles was observed, and the bonding strength test was performed to evaluate the tolerance of the adhesive in acidic and alkaline environments.

[0092] (2) Salt spray resistance test:

[0093] In the salt spray test chamber, the salt spray concentration (5% NaCl solution), spray pressure (150kPa), temperature (35°C) and time (720 hours) are set according to the relevant standards (GB / T1771-2007 "Determination of neutral salt spray resistance of paints and varnishes"). The test pieces coated with adhesive and pasted with tiles are placed in the salt spray chamber to simulate the performance of the adhesive in coastal or high-salt environments. After the test, the bonding state of the tiles and the corrosion of the adhesive surface are checked to evaluate their salt spray resistance.
