Embodiment 1

[0051] A kind of preparation method of PVC adhesive tape, its technological process is as image 3 shown, including steps:

[0052] (a) Coating acrylic pressure-sensitive adhesive on one side of the PVC film.

[0053] (b) coating the other side of the PVC film with a release agent that can be hardened by ultraviolet radiation;

[0054] The release agent formula is:

[0055] Silicone oil C715: 25wt%;

[0056] Silicone oil RC722: 70wt%;

[0057] Silicone oil A18: 2wt%;

[0058] The mixture of silicone oil and photoinitiator CD9051: 3wt%.

Embodiment 2

[0062] With reference to Example 1, the difference is that the release agent formula is:

[0063] Silicone oil C715: 40wt%;

[0064] Silicone oil RC722: 50wt%;

[0065] Silicone oil A18: 5wt%;

[0066] The mixture of silicone oil and photoinitiator CD905 1:5wt%.

Embodiment 3

[0068] With reference to Example 1, the difference is that the release agent formula is:

[0069] Silicone oil C715: 29wt%;

[0070] Silicone oil RC722: 69wt%;

[0071] Silicone oil A18: 2wt%.

Abstract

The invention discloses a preparation method of a PVC adhesive tape, which comprises the steps of: (a) coating a self-adhesive on one side of a PVC film; (b) coating a release agent that can be cured by ultraviolet radiation on the other side of the PVC film; ( c) drying by ultraviolet irradiation to harden the release agent. The method is to apply the self-adhesive first, then apply the release agent, and then use ultraviolet rays to harden the release agent. It can prevent the release agent from migrating due to the plasticizer in the PVC film due to high temperature, thereby affecting the adhesion of the release agent to the PVC film, and will not lose its catalytic effect due to the chlorine poisoning in the PVC film when using a platinum catalyst. The method of the present invention can complete the coating and drying of glue and release agent after one process, which can reduce the waste of processing time and energy, and also reduce the waste of transportation costs, and can also reduce the deformation of materials due to stretching during processing. , to avoid the problem of uneven horizontal expansion.

Description

technical field [0001] The invention belongs to the technical field of films, and in particular relates to a PVC adhesive tape and a preparation method thereof. Background technique [0002] figure 1 Shown is a PVC tape, which can be used as a low-cost protective film for chip dicing. The middle layer is a PVC film 1, the outer surface of the PVC film 1 is coated with a release agent 2, and the inner surface is coated with a glue 3. The process of making the PVC tape in China is as follows: figure 2 As shown, the PVC film imported from Japan and prepared with release treatment is used as raw material, and the self-adhesive is directly coated by the glue supply equipment, and then dried in an oven and then rolled. [0003] There is following shortcoming in above-mentioned processing step: [0004] 1. Because the PVC film imported from Japan is coated with release agent, the release agent will be aged and cracked after being heated in the oven during the glue coating proce...
