Abstract

The invention belongs to the field of light industry papermaking, and relates to an anti-sticking paper preparation method. The method comprises: uniformly mixing polyethylene and modified polyolefin according to a mass ratio of 1:0.1-0.5; heating and melting; then laminating the molten material on corona-pretreated base paper, wherein the laminating amount is 5-20 g / m<2>; cooling to obtain the laminated paper; carrying out rolling for the laminated paper by a roller with concave-convex-shaped embossing patterns, wherein the surface of the laminated paper shows the concave-convex-shaped embossing grooves; adopting a coater to uniformly coat the silicone oil on the convex surfaces of the embossing patterns on the laminated paper surface, wherein the coating amount of the silicone oil is 0.5-1.0 g / m<2>; drying at a temperature of 100-200 DEG C in three temperature stages; cooling to obtain the anti-sticking paper. With adopting the method of the present invention, the anti-sticking paper is rolled to form the strip concave-convex-shaped embossing patterns, the concave parts of the anti-sticking paper are not coated with the anti-sticking agent, such that the use amount of the silicone oil is reduced, the use amount of the organic solvent is reduced, the production cost is reduced, and the requirements of environmental protection and energy saving are achieved.

Description

technical field [0001] The invention belongs to the field of light industry papermaking, and relates to a preparation method of release paper, in particular to a preparation method of release paper with low consumption of silicone oil. Background technique [0002] The release paper is mainly pasted on the glued surface of the tape to protect the adhesive layer on the surface of the tape. The anti-adhesive paper is composed of a base paper, an isolation layer and an anti-adhesive layer. The preparation process is to coat a layer of release agent on the entire surface of the base paper (the release agent used mainly includes polyethylene), and then coat the surface of the coating layer with a layer of release agent. A layer of release agent (adopted release agent is mainly silicone oil) is coated to obtain release paper. [0003] In the existing production process of anti-adhesive paper, since the entire surface of the backing paper is coated with a layer of anti-adhesive si...
