Abstract

The invention discloses a method for making a transfer film release agent, comprising the following steps: A-1, taking acrylic resin, cellulose acetate butyrate, antistatic agent, butanone A, heating, stirring, cooling and filtering to obtain a matrix resin; A ‑2. Take methyl ethyl ketone B, wax powder A, wax powder B, and dispersant, mix and soak evenly to obtain a wax powder mixture; A‑3, take the wax powder mixture and matrix resin, mix and stir to obtain a pre-dispersed wax slurry mixture; A‑ 4. Take the pre-dispersed wax slurry mixture and grind it to obtain a coarse wax slurry; A-5. Take the coarse wax slurry and grind it to obtain a fine wax slurry; A-6. Take the fine wax slurry, butanone C, ethyl acetate, and cyclohexanone , mixed evenly to finally obtain the transfer film release agent. Through the above design, the present invention can make the obtained transfer film release agent strong in scratch resistance, strong in stability and strong in coating uniformity.

Description

technical field [0001] The invention relates to the technical field of release agents, in particular to a method for preparing a transfer film release agent. Background technique [0002] The release agent used in the carbon ribbons currently on the market generally uses a mixture of resin and wax. For resin and wax mixed type release agent, generally the wax slurry purchased on the market is directly mixed with the resin to form the release agent, resulting in uneven dispersion of the wax slurry, which is easy to produce streaks after coating, resulting in coating Cloth is uneven. In addition, the solution directly dispersed by resin and wax slurry is prone to precipitation and stratification, and it will also cause uneven coating before and after. Therefore, the existing release agent has defects such as poor scratch resistance, poor stability, and poor coating uniformity, so it needs to be improved. Contents of the invention [0003] The invention provides a new manu...
