The crayons of comparative examples 1a,2a,3a,4a were obtained by the same preparation method as in examples 1 to 4 described above.
And (3) product performance testing:
the wash graffiti crayons of examples 1-6 and the graffiti crayons prepared in comparative examples 1a-4a were evaluated for breaking strength, tinting strength, paintability, watercolor dissolution, and washability according to the following methods.
The anti-breaking force measuring method refers to QB/T1336 and 2000 crayon industry standards, and requires the anti-breaking force to be more than 4N.
The tinting strength test is to paint the sample on various surfaces of paper, skin, cloth, plastics, glass, marble, metal and the like, and to score the tinting strength:
a: the surface of each medium can be painted and colored, and the coloring power is good;
b: the color is easy to be colored on the rough surfaces of paper surfaces, cloth and the like, but is difficult to be colored on the smooth surfaces, and the color can be displayed only by repeatedly painting;
c: only the paper surface and the cloth can be painted and colored, and the other smooth surfaces cannot be colored.
The delineation test is a uniform full-paint of 50mm by 50mm size area on the lead paper with the test specimen and the delineation is scored:
a: drawing fluency, and coating the sample with uniform color;
b: paint smoothly but with uneven paint color;
c: the paint was not smooth and the paint was not uniform in color.
The water color dissolving effect test means that after a sample is painted on the lead painting paper, the drawn stitch is stained with water by a writing brush to be halated, the water-soluble condition of the stitch is observed, and the water color dissolving effect is scored:
a: the stitches are easy to dissolve in water, and the pigment is diffused on the paper surface to generate watercolor effect;
b: the traces are slightly soluble in water, and trace pigments exist in the water but cannot be diffused on the paper surface;
c: the stitch is insoluble in water, no diffusion change exists before and after water is added, and the pigment and the water are in a separated state.
The water washing performance test refers to that after color blocks with the size of 50mm x 50mm are respectively painted on the surfaces of different media such as skin, a table top, cloth and the like, the samples are washed by clean water, and the washing effect is observed; if not, adding a cleaning agent for scrubbing, observing the cleaning effect, and grading the washability:
a: the product can be cleaned by clear water without obvious residual trace;
b: the detergent can not be cleaned by clear water, and is required to be added for cleaning, so that no obvious residual trace exists;
c: after the detergent is added for cleaning, obvious residual traces still remain.
The test results are shown in table 1.
TABLE 1
As can be seen from the results shown in table 1, the wash-graffiti crayons of the present invention have a higher coloring power than the comparative examples in terms of coloring power, and can be painted and colored on various surfaces such as paper, skin, cloth, plastic, glass, marble, metal, etc., as compared with the comparative examples; the water color has good dissolving effect, and the water color can be produced by water-stunning; the paint is easier to clean, and can be cleaned by clear water after being painted on different surfaces, and no residual trace exists; in terms of delineation, better smoothness, color fineness and uniformity; in addition, their flexural strength meets the requirements of the industry.
The crayon in the comparative example was not easily colored on a smooth surface, had a water-tinged waterless color effect, and was not easily cleaned after painting. The crayons of the comparative examples were inferior to the washable graffiti crayons of the present invention in terms of tinting strength, paintability, watercolor dissolution and washability.
From the above test results, it was shown that the wash-graffiti crayon of the present invention is excellent as a wash-graffiti crayon in terms of properties including breaking resistance, tinting strength, drawing properties, watercolor dissolving effect, and water washability, as compared to conventional crayons. The product is environment-friendly, nontoxic, antibacterial and safe, and has the fragrance of natural plants; the bitter taste is provided when the children eat the food by mistake and bite, the children can be effectively inhibited from eating by mistake and biting, and the bitter taste is more suitable for the children.
