Abstract

The invention discloses coated mist release paper which is obtained by coating a matte lamination release agent on raw paper. According to a material formula, the matte lamination release agent consists of 15-70% of polyvinyl alcohol aqueous solution, 20-65% of emulsion type organosilicon release agent, 6-12% of stabilizer, 0.3-2% of emulsifier, 1.2-4.5% of catalyst, 0.5-3.5% of crosslinking agent and 2-10% of matting filler. The stabilizer is at least one of agar, gelatin and water-soluble starch; the emulsifier is at least one of sodium polyphosphate, Twain 80 and tributyl phosphate; the catalyst is platinum catalyst or benzoyl peroxide; and the crosslinking agent is methyl hydrogen polysiloxane oil. The coated mist release paper is simple in production technology flow, low in cost and convenient in operation.

Description

technical field [0001] The invention relates to a coating-type matte release paper, in particular to a matte release paper formed by coating the surface of a base paper with a film-forming material. Background technique [0002] Release paper, also known as release paper and anti-adhesive paper, is a kind of anti-adhesive paper that prevents prepreg from sticking and protects prepreg from contamination. Different organic pressure-sensitive adhesives, such as hot-melt adhesives, acrylic adhesives, and pressure-sensitive adhesives of rubber systems, require different release forces from the release paper. For the different viscosities of the adhesives that need to be isolated, the release force should be Relative adjustment is made to achieve an extremely light and stable release force when peeling. [0003] The release paper is made by pouring a certain thickness of polyethylene film layer on the surface of the base paper, and then coating the silicon release agent on the po...
