Problems solved by technology

[0002] The release agent is coated on paper and film, and the release layer accounts for a small proportion of 0.2% of the total thickness, but this layer affects the use of the entire tape
The release layer is a hard layer of a cross-linked structure formed by coating the release agent on the substrate through heating or radiation curing to prevent the adhesive from sticking. The existing release agent has poor performance at low temperatures. Stability and poor weather resistance, how to overcome the above technical problems has become the direction of efforts of those skilled in the art

Abstract

The invention discloses a light peeling-type release agent and a preparation method thereof. The release agent layer is obtained by prepolymerized resin, methylhydroquinone, 2-hydroxymethyloxetane, dodecyl glycidyl ether, and 1-hydroxy cyclohexyl phenylketone. The prepolymerized resin is obtained by the following steps: placing 40-50 parts of cyclohexyl methacrylate, 15-30 parts of beta-carboxyethyl acrylate, and carbamate (methyl)acrylic ester in a stirring barrel, and uniformly stirring the materials at a low speed to form a primary mixture; mixing the primary mixture obtained in the step 1), xylene, and 0.2-0.4 parts of benzoyl peroxide, and adding a mixture in a reaction vessel to obtain a polymer solution; stirring the polymer solution and 5-12 parts of 2-hydroxyethyl vinyl ether at ahigh speed, and heating the materials and performing heating distillation to remove xylene to obtain the prepolymerized resin. The light peeling-type release agent keeps stable low peel strength under low temperature, and increases the product weatherability.

Description

technical field [0001] The invention relates to a release agent with light release force and a preparation method thereof, belonging to the technical field of release materials. Background technique [0002] The release agent is coated on paper and film, and the release layer accounts for a very small proportion, relative to 0.2% of the total thickness, but this layer affects the use of the entire adhesive tape. The release layer is a hard layer of a cross-linked structure formed by coating the release agent on the substrate through heating or radiation curing to prevent the adhesive from sticking. The existing release agent has poor performance at low temperatures. Stability, poor weather resistance, how to overcome the above technical problems has become the direction of efforts of those skilled in the art. Contents of the invention [0003] The object of the present invention is to provide a release agent with light release force, which overcomes the defect that the ex...
