Abstract

The invention discloses a single-resisting one-side release film. A release agent layer is obtained by solidifying a release agent. The release agent comprises the following components: prepolymerizedresin, methylhydroquinone, 3-epoxypropane, dodecyl glycidyl ether, and 1-hydroxy cyclohexyl phenylketone. The prepolymerized resin is obtained by the following steps: mixing cyclohexyl methacrylate,beta-carboxyethyl acrylate, acrylic acid in a stirring barrel, and uniformly stirring the materials at a low speed to form a primary mixture; mixing primary mixture, xylene, and benzoyl peroxide, andadding 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 the materials and performing heating distillation to remove xylene to obtain the prepolymerized resin. The single-resisting one-side release film cannot generate unfavorable influence on electric property of a circuit board, increases the reliability of the circuit board, and realizes low-energy rapid light-curing under UV light irradiation.

Description

technical field [0001] The invention relates to a monoclonal antibody single-sided release film, which belongs to the technical field of release materials. Background technique [0002] In the prior art, the release film is coated with reactive silicone materials 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 purpose of the pre...
