Embodiment 1

[0020] The present invention proposes a kind of degradable glassine release paper manufacturing process, comprising the following steps:

[0021] S1: Select wood pulp long fiber and wood pulp short fiber as raw materials, and the weight ratio of wood pulp long fiber and wood pulp short fiber is 1:1, store wood pulp long fiber and wood pulp short fiber in soaking tank respectively, Soak it in an environment of 25 degrees Celsius for 12 hours;

[0022] S2: Filter the soaked wood pulp long fibers and wood pulp short fibers respectively and send them to the beating machine for continuous beating. The beating concentration is 5%, so that the beating degree of the wood pulp long fibers is 60°SR , the degree of beating of short wood pulp fibers is at 50°SR;

[0023] S3: mixing the wood pulp obtained above and adding a biodegradable adhesive for glue mixing treatment, wherein the weight ratio of the biodegradable adhesive is 0.05%, and stirring the mixed wood pulp liquid for 30 minut...

Abstract

The invention discloses a making technology for degradable Glasin release paper. The making technology includes the following steps that wood-pulp long fibers and wood-pulp short fibers are selected as raw materials, and are stored in soaking tanks respectively, the soaked wood-pulp long fibers and the soaked wood-pulp short fibers are filtered respectively and fed into a beating machine for continuous beating treatment, the obtained wood pulps are mixed, biodegradable adhesive is added, glue blending treatment is carried out, the obtained mixed wood pulp is fed into a headbox, placed onto nets, dehydrated and pressed, the temperature of obtained paper sheets is increased to 30 DEG C to 90 DEG C, and the paper sheets are subjected to surface adhesive removal treatment, overpressure drying,surface silicon coating treatment and slitting treatment. The Glasin release paper made with the technology has the biodegradability, and environment pollution of waste Glasin release paper is reduced.

Description

technical field [0001] The invention relates to the technical field of release paper, in particular to a manufacturing process of degradable glassine release paper. Background technique [0002] Glassine release paper is a release paper produced by coating release agent on glassine base paper after overpressure. Because it has been super-calendered, its texture is uniform and dense, it has good tensile strength and light transmission, and its flatness is high. It is a high-grade environmental protection material. Used to make strip labels, food packaging, pharmaceutical packaging, self-adhesive, adhesive tape or backing paper materials for sticky industrial products, especially suitable for wheel and flat die-cutting, the adhesive selected in the production process of glassine base paper Non-degradable, harmful substances in traditional adhesives, such as volatile organic compounds, toxic curing agents, plasticizers, diluents, and other additives and harmful fillers, are no...
