Comparative example 1
The granite coating in comparative example 1 differs from example 1 only in that: the ashland 250HBR cellulose in example 1 was replaced with Korea Letian B100K, wherein the mass percent of the base lacquer cellulose was 0.6%, and the mass percent of the deionized water was 30.3%;

The water-based granite coating products obtained in examples 1-4 and comparative examples 1-4 have various technical indexes measured according to HG/T4343-2012 (external inelastic), the results of examples 1-4 are shown in Table 1, and the results of comparative examples 1-4 are shown in Table 2:
examples 1 to 4 test results
TABLE 1
From the results of examples 1 to 3 in Table 1, it can be seen that: the continuous phase adopts different silicone-acrylate emulsions, which has great influence on the water resistance and the scrubbing resistance of the granite coating; different protective rubber powder and cellulose are selected as the base paint and the granulating liquid, so that the bleeding phenomenon, the storage stability and the construction effect of a system are greatly influenced; and example 4 on the basis of example 3, better construction effect is obtained by adjusting the mass ratio of the granite base paint, the granulating liquid and the continuous phase.
Comparative examples 1 to 4 test results
TABLE 2
As can be seen from the results in table 2: compared with the example 1, the base paint in the comparative examples 1 and 2 adopts cellulose with higher viscosity, and although the bleeding phenomenon and the storage stability are improved, the construction effect is poor, the toughness of the particles is strong, the particles are not easy to form, and the wire drawing phenomenon is serious. The results of the comparative example 3 and the comparative example 4 show that the quality ratio of the granite base paint, the granulating liquid and the continuous phase which is not proper can cause adverse effects on the construction effect of the granite coating, such as the phenomena of incomplete color points, poor color point separation effect, sagging and the like, so that the granite coating does not show strong stereoscopic impression and vivid stone imitation effect.
