Abstract
The invention provides a thermo-setting transfer mould release agent. The thermo-setting transfer mould release agent comprises polyisocyanates and an ingredient, wherein the ingredient comprises the following components in part by weight: 15 to 45 parts of fluorocarbon resin, 2 to10 parts of polytetrafluoroethylene micro powder, 40 to 62 parts of C4-C8 alkane, 0.2 to 0.5 part of antifoaming agent, 1 to 3 parts of flatting agent, 1 to 5 parts of release auxiliaries, and 1 to 4 parts of flatting silica, wherein the weight ratio of the polyisocyanates to the fluorocarbon resin is 1 to 8. and the method for preparing and using the mould release agent is as follows: adding the fluorocarbon resin while agitating the C4-C8 alkane and the polytetrafluoroethylene; adding the antifoaming agent, the flatting agent, the release auxiliaries and the flatting silica, and then agitating the mixture; and, regulating the weight ratio of the fluorocarbon resin to the polyisocyanates in the product to be 8 to 1. The acquired mould release agent is coated on a PET (Polymer) film by a mesh plate and then dried for the use. The mould release agent is not transferred after being transfer-printed, so that the performances of the printing oil are not affected; the bottom film has no change after transfer-printing, and the friction resistant and solvent resistant performances are very good.
Description
Technical field
The present invention relates to a kind of transfer printing parting agent, be specifically related to a kind of thermosetting transfer printing parting agent and preparation and method of use.
Background technology
Hot transfer printing parting agent in the market mainly is resinous type and wax type.Hot transfer printing parting agent grammar in use is: heat transfer film disengaging carrier thin film under heat and pressure, more securely transfer printing on stock.
The wax parting agent is the most a kind of parting agent of purposes.But the part wax in the wax parting agent can move with pattern, and fused wax can be penetrated in the printing ink, thereby influences color.Therefore not good in the tack of pet sheet face, and also not anti-solvent.In transfer process, temperature is too high or mistake is low all can be to the pattern generating influence of transfer printing.It is poor that many resin type parting agents are laid property, and release layer takes place crisply firmly after the film forming, only is suitable for the transfer of hard surface.And the not anti-solvent of resin type parting agent, not good in the tack of pet sheet face yet.In the silk-screen process, because the influence of scraper plate and solvent, if chromatography too much will seriously have influence on the transfer printing effect.
In view of this, the inventor develops a kind of thermosetting transfer printing parting agent and preparation and method of use on the basis through a series of research and test, and this case produces thus.
