The preparation method of the double-component ceramic tile glue comprises the following steps: stirring all components in the latex for 5-8 minutes until the components are uniformly mixed to obtain the latex; stirring all the components in the powder for 3-5 minutes until the components are uniformly mixed to obtain the powder; and adding the powder into the latex, and stirring for 5-8 minutes at 25 ℃ until the powder is uniformly mixed to obtain the tile glue. The components in examples 1-3 and comparative examples 1-4 are prepared according to the steps to obtain the tile glue, and the performance of the tile glue is tested.
Test section
The tile adhesives obtained in the above examples 1-3 and comparative examples 1-4 are subjected to performance testing according to ceramic tile adhesive JC/T547-2017 and enterprise execution standard Q/SDKS 099-2021, wherein the original tensile adhesive strength is the strength after the tile adhesive is formed and cured for 28 days, the tensile adhesive strength with the airing time of not less than 20min is the strength after the tile adhesive is formed and cured for 28 days, and the airing time is not less than 20min, the tensile adhesive strength after soaking is the strength after soaking and curing for 14 days, and the tensile adhesive strength after thermal aging is the strength after thermal aging and curing for 21 days; the temperature is raised to the temperature rise value of the ceramic tile glue within 24 hours when the formed ceramic tile glue meets water vapor or seeps water, the environment temperature is 5 ℃, the humidity is 90 percent. The specific results of the tile adhesive performance test are shown in table 1.
Table 1 results of performance test of tile adhesives
As can be seen from the above examples 1 to 3, the original tensile adhesive strength of the tile adhesive provided by the present application can reach above 0.71MPa, and after air-drying, water immersion and thermal aging, the tensile adhesive strength can still reach above 0.54MPa, which meets the technical requirements of the C2 reinforced cement-based adhesive in JC/T547-2017. In addition, the temperature of the tile adhesive can be raised to 7-9 ℃ within 24 hours after the tile adhesive is subjected to water vapor or water seepage. The difference between the comparative example 1 and the example 1 is that the latex is replaced by water in the comparative example 1, namely the water cannot form inert protection to calcium oxide, and reacts to generate heat when meeting water, so that the purpose of quick drying and solidification can be achieved, and meanwhile, due to the existence of the mortar stabilizer, the temperature of the tile glue can be raised by 3 ℃ after meeting the water, but the raised temperature and the tensile adhesive strength are lower than those of the examples 1-3. The difference between the comparative example 2 and the example 1 is that the powder of the comparative example 2 does not contain calcium oxide, that is, the tile glue does not contain raw materials capable of generating heat, so that the tile glue in the comparative example 2 can not achieve the effect of quick drying, and also has the effect of warming. The difference between the comparative example 3 and the example 1 is that in the comparative example 3, water is used for replacing latex, mortar stabilizer is not contained in powder, and calcium oxide reacts with water to generate heat, so that the tile adhesive does not have the performance of heating and keeping warm. The difference between the comparative example 4 and the example 1 is that the mortar stabilizer is not added in the powder, and the calcium oxide has no inert protection and reacts immediately when meeting water, so that the effect of temperature rise and heat preservation is not achieved.
In conclusion, the ceramic tile adhesive has the advantages that through the addition of the two-component materials, the synergistic effect among the materials is fully exerted, the ceramic tile adhesive is endowed with good bonding, warming and warming performances and quick drying performances, the construction is convenient and efficient, and meanwhile, the phenomena of hollowing, cracking, even falling and the like of the ceramic tile can be prevented.
While the invention has been described with reference to specific embodiments, the scope of the invention is not limited thereto, and those skilled in the art can easily conceive various equivalent modifications or substitutions within the technical scope of the invention. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
