Problems solved by technology

With the continuous in-depth research in the field of pressure-sensitive adhesives, the requirements for pressure-sensitive adhesives have become more and more stringent. The release layer is formed by coating the release agent on the substrate and heating or radiation curing. The hard layer of the cross-linked structure has anti-sticking effect on the adhesive. The existing release agent has unstable performance at low temperature 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 double-resisting one-side release material. The release material comprises a base film layer, a release agent layer coated at the upper surface of the base film layer, an antistatic coating layer coated at the lower surface of the base film layer, and the release agent layer is obtained by solidifying a release agent. The release agent comprises the following components:prepolymerized resin, methylhydroquinone, 3-epoxypropane, dodecyl glycidyl ether, and 1-hydroxy cyclohexyl phenylketone. The prepolymerized resin is obtained by the following steps: mixing a primary mixture, xylene, and benzoyl peroxide, adding a mixture in a reaction vessel to obtain a polymer solution; stirring the polymer solution and 2-hydroxyethyl vinyl ether at a high speed, and heating thematerials and performing heating distillation to remove xylene to obtain the prepolymerized resin. The release material keeps stable low peel strength under low temperature, and realizes low-energy rapid light-curing under UV light irradiation.

Description

technical field [0001] The invention relates to a double-antibody single-sided release material, which belongs to the technical field of release materials. Background technique [0002] In the prior art, the release material is coated with a reactive silicone material on the surface of the film substrate, and then made into a traditional release film. With the continuous in-depth research in the field of pressure-sensitive adhesives, the requirements for pressure-sensitive adhesives have become more and more stringent. The release layer is formed by coating the release agent on the substrate and heating or radiation curing. The hard layer of the cross-linked structure is used to prevent the adhesive from sticking. The existing release agent has unstable performance at low temperature and 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...
