Performance test
Detection method
And (3) testing the dispersibility: adopting a direct observation method, mixing the coating, standing for 24h, and stirring by using an ink adjusting knife to observe whether the coating has hard blocks, agglomeration and precipitation.
And (3) fineness test: the blade test was carried out according to the national standard GB/T1724-1979 (89).
And (3) testing the adhesive force: the test is carried out according to the rating standard specified in the national standard GB/T9286-1988, the best rating of 0 is, and the worst rating of 5 is.
And (3) hardness testing: the test was carried out according to the pencil used as specified in the national standard GB/T6739-1986, with 13 grades from 6B to 6H.
The above-described tests were carried out for examples 1 to 11 and comparative examples 1 to 2, and the test results are shown in Table 3.
TABLE 3
Combining example 1 and comparative example 1 with table 3, it can be seen that the coating of example 1 has no hard lumps with only a small amount of precipitation, whereas comparative example 1 has a small amount of hard lumps with more precipitation; the fineness of example 1 is also smaller than that of comparative example 1. The temperature-sensitive color-changing powder modified by the 2-acrylamide-2-methylpropanesulfonic acid can improve the dispersibility of the color-changing coating, so that the temperature-sensitive color-changing powder and each component in the coating are mixed more uniformly, the possibility that the temperature-sensitive color-changing powder shows different color shades after being coated is reduced, and the attractiveness of a wall body is reduced. The sulfonic acid group in the 2-acrylamide-2-methylpropanesulfonic acid on the surface of the temperature-sensitive color-changing powder shows stronger electronegativity, and the modified temperature-sensitive color-changing powder particles show electrostatic repulsion, so that the paint has a good dispersion effect, the possibility of agglomeration of the common temperature-sensitive color-changing powder in the paint is reduced, and meanwhile, the 2-acrylamide-2-methylpropanesulfonic acid has larger steric hindrance, so that the repulsion force among the modified temperature-sensitive color-changing powder particles can be further increased, and the dispersibility of the modified temperature-sensitive color-changing powder in the paint is improved.
As can be seen by combining examples 1 to 9 with Table 3, the coatings of examples 1 to 7 had no hard lumps and a small amount of precipitates, while the coatings of examples 8 to 9 had less precipitates than those of examples 1 to 7, which indicates that the dispersibility of the coatings was further improved and the temperature-sensitive toner was less likely to agglomerate to generate precipitates, with the addition of polypropylene glycol, as compared with examples 1 to 7. The hydrogen bond is formed between the hydroxyl on the polypropylene glycol and the sulfonic acid group in the 2-acrylamide-2-methylpropanesulfonic acid, and the polypropylene glycol molecule is gathered around the 2-acrylamide-2-methylpropanesulfonic acid modified thermochromic powder through the hydrogen bond, so that the steric hindrance around the modified thermochromic powder is increased, the mutual repulsion of particles of the modified thermochromic powder is increased, and the dispersion effect of the modified thermochromic powder in the coating is further improved. It can be seen from the combination of example 8 and examples 10 to 11 that the dispersibility of the temperature sensitive toner can be further improved by adjusting the weight ratio of the polypropylene glycol to the modified temperature sensitive toner.
As can be seen by combining example 6, example 8 and comparative example 2, the overall performance of example 8 is higher than that of example 6 and comparative example 2, which indicates that the dispersibility of the coating with the modified temperature sensitive toner added alone and the coating with the polypropylene glycol added alone are inferior to those of the coating with the both mixed. The polypropylene glycol and the modified thermochromic powder can act together under the synergistic effect, so that the dispersibility of the coating is improved.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
