Problems solved by technology

Nowadays, most isolation films can withstand lower temperatures, while release agents need to be melted at higher temperatures, or synthetic films, so they cannot be used on many materials. In addition, most manufacturers produce The release agents are all low-end products, and the cleanliness, smoothness and antistatic indicators of the isolation film produced by them cannot meet the requirements of the electronics and die-cutting industries, and most of them need to be imported.

Abstract

The invention relates to the technical field of preparation of a release agent, in particular to a preparation method of an antistatic release agent. The antistatic release agent mainly comprises 100to 120 parts of reaction medium, 6 to 10 parts of resin powder, 1 to 2 parts of a coupling agent, 1 to 3 parts of an initiator, 5 to 8 parts of silicone oil, 3 to 5 parts of an antistatic agent, 3 to6 parts of starch and 1 to 2 parts of a flatting agent. The release agent prepared by the method is low in use temperature, can be used under the condition of normal temperature, has high high-temperature resistance and avoids deformation and property reduction at high temperature; in addition, the release agent can effectively reduce the adhesion ability of a release film and guarantee the release effect of the release film; meanwhile, the release film has antistatic effect and can be applied in the special technical field.

Description

technical field [0001] The invention belongs to the technical field of release agent preparation, in particular to a method for preparing an antistatic release agent. Background technique [0002] The release agent is a substance used between two materials (medium) to prevent them from sticking to each other, or to control the adhesion strength of the two to the required value, and to avoid damage to the surface of the material (medium). Wax type and solvent type. In terms of materials, the release agent can be divided into inorganic type and organic type; in terms of use, it can be divided into internal lubrication type and external isolation type. The method of use is to spray the release agent on the surface of the material (medium), and dry it at a certain temperature for a period of time, so that it can form a thin film on the surface of the mold, so as to avoid damage to the surface of the material (medium). Nowadays, most isolation films can withstand lower temperat...
