Abstract

The invention relates to the technical field of paper making, in particular to a manufacture technology of anti-folding Glassine release paper. The technology comprises the following steps: S1, preparing a piece Glassine paper as a base layer; S2, preparing a coated material; S3, forming a coated layer; S4, preparing an anti-wrinkle material: mixing 10 to 15 parts of resin, 0.5 to 1.5 parts of anantioxidant, 30 to 35 parts of polyethylene plastic particles, 5 to 8 parts of polybutadiene rubber particles, and 3 to 5 parts of polyvinyl chloride plastic particles in parts by weight, uniformly stirring, and then heating, so as to ensure that raw materials are completely molten; S5, forming an anti-wrinkle layer: uniformly spraying the anti-wrinkle material onto the outer surface of the coatedlayer with a spray gun, forming the anti-wrinkle layer after cooling, and then coating the surface of the anti-wrinkle layer with a release agent; S6, drying release paper obtained in the previous step, and then cutting the release paper into small pieces according to a specified specification. The technology can effectively improve the anti-folding capacity of the Glassine release paper, therebyimproving the overall quality, and is wide in application.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a manufacturing process of anti-folding glassine release paper. Background technique [0002] Release paper is also called release paper, anti-sticking paper, silicone oil paper. It is a kind of anti-adhesive paper that prevents the prepreg from sticking and protects the prepreg from contamination. The release paper is made of paper coated with anti-adhesive substances, and its type should be distinguished according to the difference in material, thickness, elongation, and single-sided and double-sided. [0003] Anti-adhesive paper, also known as silicone oil paper. It consists of three layers, the first layer: bottom paper; the second layer: laminating film; the third layer: silicone oil. Can be used in electronic products, automotive foam, printing, food, medical and so on. In most cases it is used with sticky materials, especially adhesive tapes. [0004] The technolo...
