Abstract
The present invention discloses a preparation method for high temperature-resistant antistatic release paper. The preparation method comprises the following steps of: coating a side surface of raw release paper with a coating machine; coating a surface on the other side with an adhesive layer; coating the surface of the adhesive layer with a high temperature-resistant film layer; after coating the high temperature-resistant film layer with an antistatic layer, performing corona-pretreatment; coating the surface of the antistatic layer with a release agent; and finally drying the coated release paper. The high temperature-resistant film layer comprises a high temperature-resistant additive and a high temperature-resistant reinforcing agent. By adding the high temperature-resistant additive and the high temperature-resistant reinforcing agent, the release paper has a great high temperature-resistant capability while the antistatic layer is reinforced. As a result the release paper provided by the invention has not only a great high temperature-resistant capability and a great ntistatic capability, but also unexpectedly the high strength capability and high stretch capability of the release paper are greatly improved. Thus, the release paper has comprehensive performance and is particularly suitable for applications in the fields of chemical engineering and the electromechanical engineering.
