The invention requires that after the ink-jet ink is sprayed on the surface of PC, the ink drops have certain diffusion and are mutually fused, the coating effect is seen, no particles exist, and finally the formulation No. 1 or No. 2 or No. 3 or No. 4 can be selected, and the formulation No. 5 is too slow to dry, so that the printing speed is influenced.
Experiment of Effect of Diisophorone on ink surface tension
Taking the metal complex solution prepared in the embodiment 3, blending the product according to the percentage of each component of No. 1, No. 2, No. 3, No. 4 and No. 5 in the table 4, mixing diethylene glycol methyl ethyl ether, tetraethylene glycol dimethyl ether, isophorone, butyrolactone and a surfactant BYK-306, putting the mixture into the metal complex dye solution, stirring the mixture at 600rpm for 20min, heating the mixture to 50 ℃, stirring the mixture until the mixture is completely dissolved, aging the mixture for 2h, filtering and filling the prepared ink by adopting a multi-stage filtration mode, wherein the multi-stage filtration mode is to sequentially filter a filter element with the filtration precision of 10 mu, 5 mu, 1 mu and 0.5 mu to obtain a finished product, and then detecting the surface tension of the finished product, wherein the result is shown in the table 4.
TABLE 4 isophorone ratio and ink surface tension in test II
The surface tension of the ink-jet ink is required to be between 30 and 35, after the ink drop is sprayed on the surface of PC, the ink drop has certain diffusion, can not excessively shrink, looks like a coating effect and has no particles, a 1# or 2# or 3# formula is finally selected, the surface tension of 4# or 5# is excessively high, and the ink drop shrinkage influence effect test of tributyllactone influencing the ink glossiness test
Taking the metal complex solution prepared in the example 3, blending the product according to the percentage of each component of No. 1, No. 2, No. 3, No. 4 and No. 5 in the table 5, mixing diethylene glycol methyl ethyl ether, tetraethylene glycol dimethyl ether, isophorone, butyrolactone and a surfactant BYK-306, putting the mixture into the metal complex dye solution, stirring the mixture at 600rpm for 20min, heating the mixture to 50 ℃, stirring the mixture until the mixture is completely dissolved, aging the mixture for 2h, filtering and filling the prepared ink by adopting a multi-stage filtration mode, wherein the multi-stage filtration mode is to sequentially filter cartridges with the filtering precision of 10 mu, 5 mu, 1 mu and 0.5 mu to obtain a finished product, and then detecting the glossiness of the finished product, wherein the result is shown in the table 5.
TABLE 5 butyrolactone proportions and ink gloss in test three
The invention requires that the surface of the PC can be corroded by the ink-jet ink, so that dye molecules enter the inner layer of the PC to play a coloring role and have certain adhesive force, but too much corrosive solvent can dissolve too much PC layer to influence the luster and the transparency, and finally the formula 1# or 2# or 3# is selected, and the formula 4# or 5# influences the luster and the transparency.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
