Problems solved by technology

[0003] The release paper produced by the existing technology requires a large amount of base paper, which is made of wood pulp. Since wood takes time to become a material, with the massive felling of wood, wood pulp will gradually be in short supply, so the cost of base paper will continue to increase. Rising, and papermaking consumes a lot of energy and pollutes a lot, which is not conducive to environmental protection
Moreover, normal release paper needs to go through three processes, and each process consumes a lot of energy. The production cost requires a large amount of silicone oil, which is more expensive, and most of the silicone oil is diluted with organic solvents. These organic solvents are volatile, toxic, It is difficult to completely recycle, which is not conducive to environmental protection
[0004] In addition, if the tension of the existing release paper is too high, the paper will be broken during the winding process; on the contrary, if the tension is too small, the winding will be loose and the edges will be irregular

Abstract

The invention discloses novel release paper which comprises 23-35 parts of base material, 10-15 parts of high molecular polymer, 1.7-3.7 parts of plasticizer, 0.5-1 part of anti-bonding agent, 1-2 parts of lubricant, 0.1-0.5 part of foamer and 0.7-1.5 parts of activator. Tension of the novel release paper is improved; stearic acid is adopted to improve tenacity of the release paper, and the release paper is enabled to realize close fitting in the process of rolling, is free of displacement and cannot be broken by pulling.

Description

technical field [0001] The invention belongs to a release paper, in particular to a novel release paper and a preparation method thereof. Background technique [0002] Release paper, also known as release paper and anti-adhesive paper, is mainly pasted on the surface of the tape to protect the adhesive layer on the surface of the tape. The traditional release paper is composed of base paper, isolation layer and anti-adhesive layer. Its preparation process is to coat a layer of release agent (mainly polyethylene) on the surface of the bottom paper of the release paper, and then coat a layer of anti-sticking agent (mainly silicone oil) on the surface of the coating layer to obtain Release paper. [0003] The release paper produced by the existing technology requires a large amount of base paper, which is made of wood pulp. Since wood takes time to become a material, with the massive felling of wood, wood pulp will gradually be in short supply, so the cost of base paper will ...
