(3) The overall performance is respectively carried out according to the following standards: the low temperature storage stability is performed according to GB6573.3, the thermal storage stability is performed according to GB6573.3, the initial drying crack resistance is performed according to GB14907, the surface drying is performed according to GB9272, the water resistance is performed according to GB1733, the alkali resistance is performed according to GB9265, the heat resistance denaturation is performed according to JG/T25-2017, the stain resistance is performed according to GB9780, the adhesive strength is performed according to GB9978, the artificial aging resistance is performed according to 1766, the purified air is performed according to GB50325, and the mosquito repellent efficacy is performed according to GB 18116.
The results of the formation tests of the examples and comparative examples are shown in Table 2.
Table 2 results of formation test of examples and comparative examples
As can be seen from comparative examples 1-2, the coating adopts the real stone paint prepared from cellulose acetate butyrate CAB, inorganic gel and self-made ceramic colored sand, has excellent sand falling resistance, can not generate the phenomenon of flowery during any spraying, improves the water resistance and the bonding strength after the cellulose acetate butyrate is added, and also improves the weather resistance of the ceramic colored sand. As can be seen from comparative examples 3 to 4, when inorganic gel and cellulose acetate butyrate were not added, they had a large influence on the sand fall resistance, the bloom and the adhesive strength. From examples 1 to 3, the surface anti-fouling performance of the paint film is obviously improved, and the water resistance and the artificial aging resistance are both greatly improved after the hydrogenated silicone oil is added. The whole coating preparation process adopts camphor tree liquid medicine as a thinner, and adds two performances of air purification and mosquito prevention on the basis of the performance of the original coating. The camphor tree-based coating with the drug effect is utilized as a medicinal material, the traditional Chinese medicine city policy planning is completely met, and the product is detected by a third party and is greatly popularized in the market.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
