Performance testing
The tile adhesives of examples 1-10 and comparative examples 1-3 were tested for their performance according to the national building material industry Standard JC/T547-2005 ceramic wall and floor tile adhesive, and the results are shown in Table 1.
Table 1 different tile glue performance test results
As can be seen from the performance test results in Table 1, the tensile adhesive strength of the aqueous environment-friendly tile adhesive in examples 1-10, the tensile adhesive strength after soaking, the tensile adhesive strength after thermal aging, the tensile adhesive strength after freeze-thaw cycling and the tensile adhesive strength after cooling for 20min are all higher than those in comparative examples 1-3, and the slip distance is lower than those in comparative examples 1-3, so that the aqueous environment-friendly tile adhesive provided by the invention has good adhesiveness, can still maintain higher adhesive strength after long-term use, has good weather resistance, and is not easy to fall off or slip.
Further analysis shows that the tensile strength of the adhesive in examples 6-9 is higher than that in example 5, which indicates that the adhesive property of the water-based environment-friendly tile adhesive can be further improved by adding an antifoaming agent, a pure acrylic emulsion, a vinyl acetate emulsion or a reinforcing agent in the components. The tensile adhesive strength of example 10 is higher than that of example 5, which shows that the performance of the water-based environment-friendly ceramic tile adhesive is further improved by adopting the preferred preparation method of the invention.
While particular embodiments of the present invention have been illustrated and described, it would be obvious that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
