Examples 5,

The process adopts the environment-friendly water-based ink grinding processing equipment for transfer printing to process, adopts zirconia beads as a grinding medium of the ink grinding processing equipment in order to ensure the maximum grinding efficiency of ink grinding, and sets the pre-dispersion time of the process to be 40min when the pre-dispersion rotating speed is 2000 r/min.

As shown in FIGS. 15-16, when the pre-dispersion rotation speed is 2000r/min, the pre-dispersion time is set to 10,20,30,40,50min, and the test results of pre-dispersion and dispersibility tests are respectively carried out on the ink with the same proportion: with the increase of the pre-dispersion time, the particle size of the ink gradually decreases from 4.19 μm of 10min of initial dispersion to 3.34 μm of 40min of dispersion, and after 40min of pre-dispersion, the change amount of the particle size of the ink is 0.02 μm and basically tends to be unchanged. When the pigment is dispersed for 10min, the distribution range of the particle size is wider, and a small amount of particle size is still above 10 mu m, which indicates that the pigment and the resin are not fully and uniformly mixed when the pigment is pre-dispersed for 10 min; when the ink is pre-dispersed for 40min, the particle size distribution range of the ink is narrowed, and all the particle sizes are distributed between 0.1 and 10 mu m; the particle size distribution range of 50min of pre-dispersion is similar to that of 40min of pre-dispersion, and the difference is not large, so that when the pre-dispersion time is 40min, the particle size of the ink (95%) is the minimum and the distribution range is the narrowest.

Examples 6,

In order to ensure the maximum grinding efficiency of ink grinding, the process adopts the zirconium oxide beads as the grinding medium of the ink grinding processing equipment, the pre-dispersion time of the process is set to be 40min when the pre-dispersion rotating speed is 2000r/min, and the mass ratio of the zirconium oxide beads to the ink is set to be 2: 1.

In the ink formulation process, a milling process is essential. The addition of zirconia beads is necessary for the milling process. The quantity of the zirconia beads plays a decisive role in the refining process of the ink particle size, so that under the conditions that the pre-dispersion rotating speed is 2000r/min and the pre-dispersion time is 40min, the mass ratio of the zirconia beads to the ink is 1: 1, 2: 1 and 3: 1, the ink with the same proportion is respectively ground for 120min, and then the dispersibility test is carried out.

As shown in fig. 17, the experimental results are: the particle size of the ink gradually decreases from large to small and increases from small to large as the ratio of the zirconia beads to the ink is gradually increased. The results show that the ink has the smallest particle size when the mass ratio of the zirconia beads to the ink is 2: 1. When the mass of the zirconia beads and the ink is 1: 1, the particle size distribution range of the ink is wide, and the distribution is uneven, which indicates that the number of the zirconia beads is too small, and the ink cannot be fully refined and ground by the zirconia beads; when the mass of the zirconia beads and the ink is 2: 1, the quantity of the zirconia beads is just matched with the quantity of the ink, and the ink can be fully refined and ground by the zirconia beads; when the mass of the zirconia beads and the ink is 3: 1, the number of the zirconia beads is too large to flow sufficiently in a limited space, so that the process of grinding and refining the ink is hindered, and the particle size of the ink tends to increase. It follows that zirconia beads are an essential product for milling and refining the ink, but the more zirconia beads, the better, and the best dispersibility can be obtained only when the amount of zirconia beads and the amount of ink are matched.

Examples 7,

In order to ensure the maximum grinding efficiency of ink grinding, the process adopts zirconia beads as a grinding medium of the ink grinding equipment, the pre-dispersion time of the process is set to 40min when the pre-dispersion rotating speed is 2000r/min, the mass ratio of the zirconia beads to the ink is set to 2: 1, and the grinding time is set to 2h.

In the milling process, the milling time is also decisive for the process of ink thinning. The grinding time was set to 0.5,1,1.5,2,2.5h, and the ink of the same formulation was ground and tested for dispersibility.

As shown in fig. 18-19, the experimental results are: the ink particle size gradually becomes smaller as the milling time increases. The particle size of the ink (95%) was the smallest when the milling time was 2h. When the milling time is 2.5 hours, the ink particle diameter tends to become large. Because the grinding time is too long, the grinding resin is easy to break, and the pigment particles which are continuously thinned are easy to be coated by the resin in a pile, so that the particle size is enlarged. Along with the increase of the grinding time, the distribution range of the particle size is gradually narrowed, the distribution range is reduced from the initial 0.1-30 mu m to 0.1-10 mu m, the narrowing of the distribution range represents that the particle size distribution is more uniform, and the grinding effect is better; the distribution range of grinding for 2h and the distribution range of grinding for 2.5h are not greatly different, and the distribution ranges are all 0.1-10 mu m. It follows that the ink has the smallest particle size and the best dispersibility when the milling time with the zirconia beads is 2 hours.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
