Embodiment 1

[0013] Imported bleached sulfate "Silver Star" coniferous wood pulp is selected, with a beating concentration of 3.5% and a refining degree of 65 O SR, fiber wet weight 6g, adding alkyl ketene dimer synthetic glue to the pulp, the addition amount is 1% (on dry basis), and 2.5% (on dry basis) special starch for papermaking in the pulp for mixing. In this embodiment , the paper-making special starch is: modified starch, of course, it can also be other paper-making special starches such as cationic starch, oxidized starch and amphoteric starch.

[0014] After double-sided molding and dehydration in the wire section, pressing and extrusion dehydration, first drying in the front drying section, and entering the sizing machine to soak the surface of the paper sheet, the solution preparation material is surface sizing starch 45% + polyvinyl alcohol 50% + The binder is synthesized at 5%, and the concentration is controlled at 5.5%, followed by secondary drying and calendering pretrea...

Embodiment 2

[0016] Imported bleached sulfate "Silver Star" coniferous wood pulp, beating concentration 4.0%, refining degree 70 O SR, fiber wet weight 5.5g, adding alkyl ketene dimer synthetic glue to the pulp, the addition amount is 1.3% (on dry basis), and 2.8% (on dry basis) special starch for papermaking in the pulp for mixing. In this embodiment Among them, the paper-making special starch is: modified starch, of course, it can also be other paper-making special starches such as cationic starch, oxidized starch and amphoteric starch.

[0017] After double-sided molding and dehydration in the wire section, pressing and extrusion dehydration, first drying in the front drying section, and entering the sizing machine to soak the surface of the paper sheet, the solution preparation material is surface sizing starch 45% + polyvinyl alcohol 50% + The binder is synthesized at 5%, and the concentration is controlled at 6.0%, followed by secondary drying and calendering pretreatment. The temper...

Embodiment 3

[0019] Imported bleached kraft "Silver Star" coniferous wood pulp, beating concentration 5.0%, refining degree 75 O SR, the wet weight of fiber is 5.0g, the amount of alkyl ketene dimer synthetic glue added to the pulp is 1.6% (on a dry basis), and the amount of paper-making special starch added to the pulp is 3.2%, mixed in the pulp tank, in this implementation In an example, the paper-making special starch is: modified starch, of course, it can also be other paper-making special starches such as cationic starch, oxidized starch and amphoteric starch.

[0020] After double-sided molding and dehydration in the wire section, pressing and extrusion dehydration, drying in the front drying section, and entering the sizing machine to soak the surface of the paper sheet, the solution preparation material is surface sizing starch 45% + polyvinyl alcohol 50% + adhesive 5% of the agent is mixed and dissolved, and the concentration is controlled at 6.5%, followed by secondary drying and...

Abstract

The invention discloses a Glassine base paper production method, which comprises the following steps: a, bleached sulfate softwood pulp is selected and used as a raw material; b, an alkylketene dimmer synthetic glue and paper making special starch with a weight percentage of 5% are added in the bleached sulfate softwood pulp; c, a net part is formed via double-faced bidirectional dehydration, and positive contrast is reduced; d, press dewatering is performed after the formation; e, a front drying part performs drying after dewatering; f, a paper page enters a large roller radial pressing area and passes through a soaking solution, and a certain quantity of adhesive films cover the surface of the paper page; g, the drying part performs shaping and drying after film coating; h, the processed paper is further treated by a steel roller in high-temperature calendaring intermediate; y, the paper is cut and packed by a rewinding machine. Compared with the prior art, the Glassine base paper production method has the technical characteristics of strong infiltration resistance, reduction of the use amount of silicon oil, increment of the surface strength of the paper pages and low probability of linting, and can greatly improve the production efficiency.

Description

technical field [0001] The invention relates to a method for producing glassine base paper. Background technique [0002] Glassine base paper is the basic material of Glassine paper, which belongs to the category of industrial paper. Glassine base paper is overpressured and sprayed with silicone oil to make self-adhesive backing paper. It has the characteristics of high temperature resistance, moisture resistance, and oil resistance. It is mainly used as backing paper for packaging labels in industries such as medicine and food. The glassine paper produced by the current glassine base paper process is prone to silicone oil penetration, resulting in poor peeling force of the label, high consumption of silicone oil, and technical defects such as low surface strength and easy shedding of the base paper, which cannot achieve high-speed automatic Labeling requirements reduce production efficiency. Contents of the invention [0003] The technical problem to be solved by the pr...
