Problems solved by technology

[0005] Corona treatment method: The adhesion is improved by corona treatment on the surface of the PVC sheet. The cost of corona treatment is low, but the stability of the treatment effect is poor, and the corona treatment effect will gradually weaken with time. , especially when the film material is stored in an environment with high humidity, the effect of corona treatment weakens faster
[0006] Coating treatment method: by adding a coating to the surface of the PVC sheet to improve the adhesion, the coating treatment effect is better, and the surface tension is not affected by time, but the process is complicated, the cost is high, and it does not meet the requirements of green and environmentally friendly countries. strategy

Embodiment Construction

[0028] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see Figure 1-2 :

[0029] A PVC sheet with high adhesion, the upper surface of the sheet 1 is an adhesion surface 11, and the lower surface is a smooth surface 12, and a plurality of bumps 13 are evenly distributed on the adhesion surface 11, and the bumps 13 are The size is 1-100 μm.

[0030] The size of the above-mentioned bumps 13 is 1-100 μm, which means that the three dimensions of the bumps 13 are all 1-100 μm. The size between the bumps 13 is also 1-100 μm.

[0031] Preferably, the size of the bumps 13 is 1-10 μm.

[0032] The above-mentioned PVC sheet is a transparent material.

[0033] The above bumps 13 are semi-hemispherical.

[0034] The present invention also provides a production equipment for PVC sheets with high adhesion, the production equipment is a pressing roller 2 or a sheet-discharging roller, and the surface of the pressi...

Abstract

The invention belongs to the technical field of PVC printing, and relates to a high-adhesive-force PVC sheet. The upper surface of the sheet is provided with an adhesive surface, and the lower surfaceof the sheet is provided with a smooth surface; a plurality of convex points are uniformly distributed on the adhesive surface; and the size of the convex points is 1-100 [mu]m. The invention furtherprovides production equipment of the high-adhesive-force PVC sheet. The production equipment is a pressing roller or a sheet discharging roller, a plurality of concave points are uniformly distributed on the pressing roller or the sheet discharging roller, the size of the concave points is 1-100 [mu]m, and the concave points are formed through fine carving. According to the high-adhesive-force PVC sheet provided by the invention, the combination firmness of the PVC sheet and printing ink can be remarkably improved, the technology is simple, the cost is low, and the texture of the PVC sheet isnot influenced.

Description

technical field [0001] The invention belongs to the technical field of PVC printing, and relates to a high-adhesion PVC sheet and production equipment thereof. Background technique [0002] In the technical field of PVC printing, the ink printed on the surface of the PVC sheet is easier to fall off than the ink printed on the surface of the paper, mainly because the surface tension of the PVC sheet is low, and the ink is difficult to firmly adhere to its surface. Generally, the surface tension of the PVC sheet must reach a certain level to be firmly combined with the ink. [0003] In order to enhance the firmness of the combination of PVC sheets and printing inks, technicians started with inks and developed many high-adhesion inks. However, due to the limitations of the characteristics of PVC sheets, the methods of improving inks have limited effects after all. [0004] Therefore, in order to maximize the firmness of the combination of PVC sheet and printing ink, it is nece...
