Table 1, examples 1 to 5 and controls 1 to 10 Performance tests
As can be seen from the data in Table 1, the inorganic glaze coatings for exterior walls provided by the embodiments 1 to 5 of the present invention have high adhesion, and are superior to the control in salt spray resistance, discoloration resistance and scrubbing resistance.
From the comparison between the example 1 and the comparison group 1, it can be known that when the sericite powder is not added, various performances of the inorganic glaze coating of the exterior wall are reduced; from the comparison between example 2 and control 2, it can be seen that when no quartz powder is added, the adhesion is increased compared with control 1, but no qualitative change occurs, and the performances of control 2 are still reduced; similar results were obtained from the comparison of example 3 with control 3, the comparison of example 4 with control 4, and the comparison of example 5 with control 5. When the components such as sericite powder, quartz powder, white cement, zeolite powder, sierozem powder, triple superphosphate powder, mineral powder and the like are singly or excessively added, although the salt spray resistance is improved compared with the salt spray resistance without the raw materials, the adhesion force cannot reach the optimal value because the raw materials contain unreacted materials.
Therefore, the inorganic glaze coating for the exterior wall can show excellent adhesion performance and weather resistance only when the inorganic glaze coating for the exterior wall simultaneously contains various raw materials in parts by weight.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
