Problems solved by technology

Due to the poor compatibility between wax and organic solvents, most of them heat the solvent to dissolve the wax during production, and heat insulation coating during production to prevent wax precipitation. The production control requirements are strict and the release stability is poor.

Abstract

The invention discloses a hot stamping mold release agent and a preparation method and application of the hot stamping mold release agent, and belongs to the technical field of mold release agent preparation. The hot stamping mold release agent comprises the following components in percentage by mass: 1-6% of oxidized polyethlene wax, 20-50% of methylbenzene, 10-20% of xylene, 3-10% of methylal and 10-40% of butanone. According to the invention, the oxidized polyethlene wax is adopted as a main body, and the use amount of oxidized polyethlene wax and various organic solvents is controlled, so that the prepared hot stamping mold release agent has relatively high mold release force and cutting clear rate, is relatively good in adhesion, is easy to strip, and can be applied to hot stamping cigarette case coating at the normal temperature. The preparation method is simple, is relatively good in cost, and can be applied to large-scale production.

Description

【Technical field】 [0001] The invention belongs to the technical field of release agents, in particular to a hot stamping release agent and its preparation method and application. 【Background technique】 [0002] The release agent is mainly composed of OP wax and OPE wax. It is a low-viscosity transparent resin with release, film-forming and adhesive properties. It mainly plays a role in buffering the adhesion of PET film and transfer layer or printing layer. effect. Since the solvent in the release agent volatilizes quickly, when preparing the release agent, pay attention to controlling the viscosity; at the same time, pay attention to the transparency and coating amount of the release agent, otherwise it will affect the effect of hot stamping and molding. printing effect. [0003] At present, release agents are mostly used in the fields of mold release, release paper coating, rubber products or food processing. The release agent should not only satisfy the good wettabilit...
