1314896 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a plastic dyeing apparatus and method thereof, and more particularly to a plastic dyeing apparatus and method for dyeing L, H, and coloring powder for dyeing. [Prior Art] Since the development of the petrochemical industry, plastic materials have been used in various calves due to their good physical processing and strong insulation. * ^ 土座兴^ In the mouth of the industry, including the products of people's livelihood, information electronics, fathers and workers, including the food, clothing, housing, transportation, education, and long-term planting facilities, it can be seen that the plastic materials are The shadow of the public life is changing. Therefore, in the production process of plastic materials, the plastic material and the toner are often mixed by a single-screw extrusion twin-screw extruder or a mixer to provide a material to meet the above various application requirements. ;

The mixing mechanism of the rod extruder or the mixer is mainly to make the plastic; I: the shear flow is widely generated therein, and the toner is mixed with the plastic material to change the color of the plastic material. Mixing energy consumption ί: The mixing mode of the mixing master needs to be greatly reduced. =: The length of the mixing time will affect the production efficiency and other factors. Limits: Time to live, you need to increase the amount of toner added.

The color development. In other words, when the amount of I toner added is limited by the time of mixing, the plastic material will be caused: dyeing: The lack of saturation of the Junhao phase causes the lack of chromatic aberration. 20 !314896 Therefore, plastic dyeing equipment and methods which have good color development and can reduce the amount of toner added are practical technologies that are urgently needed in the plastics industry, and are worthy of active research and development. SUMMARY OF THE INVENTION The present invention provides a plastic dyeing apparatus and method thereof for increasing the color rendering property of the color value in the soil glue, so that the color of the dyed plastic of the present invention reaches the same state as the hue technique. The color required for the plastic; the amount used is less, and the amount of toner is reduced. "Color core 10 15 The present invention provides a method for dyeing plastics" comprising: (4) to (10) heavy two providing 01 to 1 part by weight of a binder; (4) > a toner in the powder, and using a stretching flow The mixing device is mixed with far-color powder, "glue and the adhesive.

~x~i--ί_ I I ---- 0.01 揭口 In the sample m, codes E and F are samples of the plastic material composition of the present embodiment. It can be known from the color difference data of the samples a and qd in Table 3 that the plastic dyeing of the C sample in the present embodiment is improved by the combination of the single: rod (four) machine and the stretching flow mixing device, so that the toner dispersion of the sample C in the present embodiment is improved, so that The larger color difference ^ is called, and if you want to maintain the saturation of A#_, the color material is reduced to. 22. Example D. In addition, it can be seen from the toner usage data of the samples of Table 3 that the addition of the binder and the dispersant does require nearly 10 15 of the same hue to reduce the amount of toner, which saves about 6% of the toner. It can be known from the data of the sample of Table 8 and the sample of the sample that the plastic material composition after dyeing using the plastic material composition disc of the present embodiment has a significant increase in color development: thus, a color difference of up to L95 is generated. . From the color data of the aaf sample of Table 3, it can be known that the coloring amount of the toner is reduced by about 20% by using the (4) material composition formula of the present embodiment and dyeing with a plastic dyeing apparatus. Another month, reference is made to Figs. 3A, 3B and 3C, which show the compression/stretching region i2i in the stretch flow mixing device 12 of another preferred embodiment of the present invention. As shown in the figure, the inner diameter of the compression/stretching region 121 is regularly varied by a different number 1E. As the number of scaling changes increases, the probability of breakage and stretch flow of the plastic droplets within the plastic and toner is increased, resulting in good dispersion and distribution. As can be seen from the above, the plastic dyeing apparatus and method of the present invention provide plastic, adhesive and toner to a stretching flow mixing device 20 1314896 =: dyeing, so that the toner and _ Among them, the color development of 逹9 plus color powder can reduce the amount of toner used.
