This is a visual effect not possessed by this patent.
The traditional spray 3D stereoscopic coating has the defects that the large-scale coating line cannot be formed due to the fact that the required magnetic die is more and the manual spray operation is adopted because the product area is smaller, and boundary lines are easy to permeate and spread and are not clear enough, so that the stereoscopic effect is poor. But the coil coating has very high coating efficiency of a production line due to the special construction process, and the 3D three-dimensional pattern produced by the 3D three-dimensional multicolor printing paint through the continuous roller coating process by the embossing roller has the three-dimensional visual effect, so that the efficiency can be improved, the quality can be ensured, and the cost can be reduced.

The invention further aims at providing a preparation method of the 3D multicolor printing paint.
Another object of the present invention is to provide an application of the above 3D magical color printing paint, which requires a high degree of process with roller coating, fast combination, fast roll filling, and easy scraping. The process adopts a three-coating roller coating process of primer, printing paint and varnish, so that the pattern and line effects of the product are displayed clearly, finely and clearly in layers and with strong stereoscopic impression.
The 3D multicolor printing paint prepared by the invention is required to have high solid content, low viscosity and excellent fluidity.

Table 2 specific proportions (parts by weight) of the components in each example and comparative example
Comparative examples 9 to 14
The 3D magical color printing paints of comparative examples 9 to 14 were prepared in the same manner as in example 1, except that the formulation was as shown in table 3:
table 3 formulas of comparative examples 9 to 14
Note that: "/" indicates that the composition is the same as in example 1.
Application example 1
The viscosity of the prepared 3D multicolor printing paint is detected, meanwhile, the prepared paint capable of being produced by continuous roller coating is coated on an aluminum profile by adopting a knife coating and roller coating process, the printing ink filling effect and the film adhesion (cup convex), high temperature resistance, T bending resistance and other performances of the coating are detected, specific detection standards are shown in table 4, and test results are shown in tables 5 and 6.
Table 4 test criteria
TABLE 5 Performance test data for samples of examples and comparative examples
Table 6 performance test data for each comparative sample
As can be seen from the results in Table 5, the 3D multicolor printing paint of examples 1 to 3 can be provided with the characteristics of rapid roll filling, clear and full lines, attractive coating, good film adhesion (cup convex), high temperature resistance, excellent T-bend and the like.
However, as is clear from comparative example 1, the ratio of the amino resin to the polyester resin is enlarged, the difference in high temperature resistance color change is small, and slight defects occur in cupping (varnish) and T-bend properties.
As is clear from comparative example 2, the ratio of the polyester resin to the amino resin was increased, and the difference in high-temperature-resistant color change was increased.
As is clear from comparative examples 3 and 4, the extreme amount of the leveling agent is changed, the difference between the paint flowing and filling roller and the screen printing appears, the line is under clear and saturated on the screen printing in comparative example 3, and the fact that the product quality and the process quality of the filling roller are not substantially influenced by increasing the amount of the leveling agent through comparative example 4 is found. It was unexpectedly found from comparative example 5. The consumption of an acid catalyst is reduced, the product viscosity and the line saturation of screen printing are reduced, the finishing oil has slight biting color, and the high-temperature-resistant color change is also increased; the proportion 6, directly increase the dosage of acid catalyst, T bend becomes worse, and cup bulge has slight fracture phenomenon. From comparative example 7, it was found that the reduction of the pigment amount and the increase of the pearl powder amount resulted in deterioration of both T-bend and high temperature resistance, undersaturation of the lines and no obvious stereoscopic effect in addition to the increase of the viscosity. From comparative example 8, it was found that the overall finish effect was not sufficiently glaring by increasing the pigment amount and simultaneously decreasing the pearl powder amount.
As can be seen from table 6: from comparative examples 9 and 10, it was found that the polymerized partially methylated amino resin stiffened the film-forming layer and deteriorated flexibility. Polymeric total butyl etherified amino resins. Besides directly influencing the viscosity of the paint system, the color biting phenomenon appears on the finishing oil effect. It was found from comparative examples 11 and 12 that the oil absorption level of the pigment had a direct effect on screen printing quality, such as line saturation and roll fullness. As is clear from comparative examples 13 and 14, the use of the defoamer type has a direct effect on the process effect of the product application, and comparative example 13 uses the silicone type defoamer, has a slight peeling phenomenon in the cup bulge test of the recoatability, but is best in high-temperature discoloration resistance; the comparative example 14 uses a mineral type defoamer, which has poor defoaming effect, a slight pinhole in the pattern, and undersaturation of the line.
In conclusion, the 3D multicolor printing paint of the invention achieves unexpected technical effects. The coating of the invention can be applied to the construction and decoration industries, and is suitable for indoor and outdoor suspended ceilings, wall boards, honeycomb boards, decoration panels for advertisements, aluminum suspended ceiling buckle plates, household appliance panels and metal panels.
