Problems solved by technology

[0003] In the existing production process of anti-adhesive paper, a layer of silicone oil with anti-adhesive effect is coated on the entire surface of the backing paper, and the raw material price of the silicone oil is expensive, which increases the production cost, and most of the silicone oil is diluted with organic solvents. Organic solvents are volatile and difficult to completely recycle. The production process is not only toxic, but also not conducive to environmental protection.

Abstract

The invention discloses release paper for adhesive tape and a preparation method of the release paper. The release paper for the adhesive tape comprises a base material, a lamination layer, an anti-sticking agent layer, a thin film layer, a matte coating and a release agent coating. The matte coating is prepared from, by weight, nano-silica powder, nano-alumina powder, a silane coupling agent, vinyl siloxane, hydrosiloxane, a solvent, platinum and an initiating agent; the release agent coating is prepared from, by weight, amino silicon oil, a cross-linking agent, a chromium-containing organic complex, an active thinning agent, an antioxidant, a photoinitiator, high-viscosity methyl silicone oil, 3-methyl-1-pentyn-3-ol and an azo-compound foaming agent. According to the release paper for the adhesive tape, gaps are coated with an anti-sticking agent, therefore, the usage amount of silicon oil is reduced, and the usage amount of the organic solvent is reduced; the produced release paper is good in anti-sticking property, the production cost is reduced, the environmental protection and energy saving requirements are met, and great development potential and market need are achieved.

Description

technical field [0001] The invention relates to the technical field of release materials, in particular to a release paper for adhesive tape and a preparation method thereof. Background technique [0002] The release paper is mainly pasted on the glued surface of the tape to protect the adhesive layer on the surface of the tape. The anti-adhesive paper is composed of a base paper, an isolation layer and an anti-adhesive layer. The preparation process is to coat a layer of release agent on the entire surface of the base paper (the release agent used mainly includes polyethylene), and then coat the surface of the coating layer with a layer of release agent. A layer of release agent (adopted release agent is mainly silicone oil) is coated to obtain release paper. [0003] In the existing production process of anti-adhesive paper, since the entire surface of the backing paper is coated with a layer of anti-adhesive silicone oil, the raw material of the silicone oil is expensive...
