Now the quality of redispersible polymer powder RDP is relatively stable. The quality of its products is also similar. How to choose redispersible latex powder, generally when making the formula, there is really no way to start, and there is no effective way other than putting it into the product for experimentation. Redispersible latex powder is the reprocessing process of emulsion. The selection of suitable redispersible latex powder should be considered from the following aspects:

Redispersible latex powder has the characteristics of good fluidity, uniform particle size and good dispersibility after redispersion. After the latex powder particles are mixed with water, they can be restored to the original emulsion state and maintain the characteristics and functions of organic adhesives with HPMC.

The effect of the content of redispersible latex powder RDP on the compression ratio of the polymer mortar itself indicates that the polymer improves the toughness of the mortar. The weighted average of each relevant point can quantitatively analyze the influence level of the redispersible polymer powder content on the performance of the polymer mortar itself

Ordinary tile adhesive formulation ingredients: cement 330g, sand 690g, hydroxypropyl methyl cellulose 4g, redispersible latex powder 10g, calcium formate 5g;

(1) The effect of the fresh mortar: ① Prolong the working time and adjustable time; ② Improve the water retention performance to ensure the hydration of cement; ③ Improve sag resistance (special modified polymer powder); (4) improve the workability (easy to construct on the base material, easy to press the ceramic tile into the adhesive).

With the increase of cement dosage, the tensile adhesive strength of ceramic tile after water immersion treatment increases, while the tensile adhesive strength of thermal aging treatment decreases with the increase of excessive cement dosage. The optimal dosage of P· 042.5 cement is 40%.
