The present invention provides a schematic view of the appearance effect of the simulated golden granite prepared in the example 1 of the present invention, and a schematic view of the appearance effect of the simulated golden granite prepared in the example 5 of the present invention, see fig. 1 and fig. 2, respectively.
FIG. 1 is a schematic view of the apparent effect of the simulated golden granite prepared in example 1 of the present invention. As can be seen from the figure 1, the simulated golden tinge mortar prepared by the method has high surface smoothness, simple color, uniform color distribution, bright color and mortar decoration effect similar to the texture of natural golden tinge Dan Biaoguan; therefore, the simulated golden tingling stone obtained by the method provided by the invention can achieve the decorative effect of golden tingling Dan Biaoguan morphology.
FIG. 2 is a schematic view of the apparent effect of the simulated golden granite prepared in example 5 of the present invention. As can be seen from fig. 2, the simulated golden tinge mortar prepared by directly mixing the base material component and the color sand component has gray dot distribution scattered on the surface, uneven gray scale, graying, dullness and mattness on the surface of the mortar, and larger texture difference from natural golden tinge Dan Biaoguan; therefore, the method can not obtain the golden tingling stone mortar with the golden tingling Dan Biaoguan appearance decorative effect.
