Abstract
The invention discloses a preparation method of an uvioresistant antibacterial release paper. The method comprises the following steps of coating one side or two sides of base paper of the release paper with a film coating layer; coating the surface of the film coating layer with a release layer; performing super press polishing on the coated release layer; coating the surface of the release layer with an antibacterial agent to obtain an antibacterial layer; coating the surface of the antibacterial layer with a polyethylene glycol terephthalate (PET) film layer; airing the antibacterial layer at the temperature of 20-25 DEG C to obtain the uvioresistant antibacterial release paper. The release paper having an uvioresistant and antibacterial function can resist tearing; by adding vinyl acetate-ethylene (VAE) emulsion, the release paper has functions of high flexibility, acid-base resistance property, ultraviolet ageing resistance and the like; meanwhile, due to the addition of organic antibacterial agents, the release paper has extremely high antibacterial effect and can be widely used in the field of chemical engineering packaging.
