Abstract

The invention discloses a release agent for a scratch-resistant high temperature-resistant OPP (Oriented Polypropylene) heat transfer film. The release agent is prepared from the following raw materials in parts by weight: 30-60 parts of polymethyl methacrylate, 10-30 parts of nanometer titanium dioxide, 5-10 parts of scratch-resistant auxiliary agent, 3-5 parts of dilauryl thiodipropionate and 50-100 parts of organic solvents. The invention also discloses a preparation method of the release agent. According to the release agent for the scratch-resistant high temperature-resistant OPP heat transfer film, the polymethyl methacrylate is modified by the nanometer titanium dioxide, good scratch-resistant property is achieved through addition of a microcrystalline wax or Nano-R 1003 serving as the scratch-resistant auxiliary agents, and good high temperature-resistant property can be obtained by addition of the dilauryl thiodipropionate. The obtained release agent can be used for a preparation process of the heat transfer film and the prepared heat transfer film has the functions of ultraviolet prevention, scratch resistance, high temperature resistance and the like; the obtained OPP heat transfer film can be used in the fields of heat transfer printing, optics, advertising graphics, and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a release agent for scratch-resistant and high-temperature-resistant OPP thermal transfer film and a preparation method thereof. Background technique [0002] Thermal transfer film is a polar material that is moisture-resistant, air-tight, soft, strong, resistant to acids, alkalis, greases and solvents, and is not afraid of high and low temperatures. The thermal transfer film currently produced on the market is prone to adhesion between the films due to the added release agent, and cannot be reused. [0003] The release agent is a low-viscosity transparent resin with release properties, film-forming properties and adhesive properties. Because the solvent in the release agent evaporates quickly, it is necessary to pay attention to controlling the viscosity during the coating process, that is, to control The solid content of the release agent is generally co...
