Foggy surface release material for high-reliability adhesive tape

Abstract

The invention discloses a foggy surface release material for a high-reliability adhesive tape. The foggy surface release material is characterized by being used in release paper of the adhesive tape;the foggy surface release material consists of the following components in percentage by weight: 5 percent of silica particles, 27 percent of acrylic polyol with an average molecular weight of 500-2000, 39 percent of resin of polyoxylene series polyol with an average molecular weight of 200-2500, 18 percent of polyethylene glycol, 6 percent of cyclomethylsiloxane and 5 percent of 1-hydroxycyclohexylphenylketone photoinitiator 184; a foggy surface antistatic coating layer adopts an ultraviolet waveband of 280-350 nm, and the diameter of each of the silica particles is 2.5-2.8 micrometers. The foggy surface release material disclosed by the invention can eliminate influences caused by static electricity on the silicone oil coating instability, is stable in release peeling force and also avoids the generation of electrostatic sparks in the production process.

Description

technical field [0001] The invention relates to a fog surface release material, in particular to a fog surface release material for high-reliability adhesive tapes. Background technique [0002] The existing release film is generally coated with a film layer (the material used is mainly polyethylene) on the surface of the bottom paper layer of the release paper, and then coated with a layer of release agent coating on the surface of the film layer. (The material used is mainly silicone oil) to obtain a release paper. However, due to the high flatness of the coating layer and the poor adhesion between the release agent coating and the coating layer, when the release paper is attached to the film coated with a high-viscosity adhesive, it is easy to cause cracks on the release paper. The release agent coating is taken away by the adhesive with greater adhesion, thus forming a difficult-to-clean release agent coating area on the partial surface of the film, destroying the overa...

Problems solved by technology

However, due to the high flatness of the coating layer and the poor adhesion between the release agent coating and the coating layer, when the release paper is attached to the film coated with a high-viscosity adhesive, it is easy to cause cracks on the release paper. The release agent coating is taken away by the adhesive with greater adhesion, thus forming a difficult-to-clean release agent coating area on the local surface of the film, destroying the overall purity and consistency of the film

Moreover, due to the excessive static electricity in the production process, the release coating layer is partially uneven, which not only affects the stability of the peeling force of the product, but also easily generates static sparks and causes fires.
