Abstract

The invention relates to a preparation process of a food-level oil-proof paperboard. The preparation process of the food-level oil-proof paperboard comprises the procedures of preparing pulp, manufacturing paper with pulp, sizing, press-polishing and coating, wherein surface sizing starch is adopted for the sizing of the backside of the paper during the sizing and coating processes. By adopting oil-proof surface sizing starch to replace an oil-proofing agent in the prior art to perform the surface sizing treatment on a product, the preparation process of the food-level oil-proof paperboard not only reduces product cost (the cost of each ton of the paper can be reduced by about 800 Yuan), but also has good grease percolation resistant (oil-proof) effects, realizes the purpose of optimizing the production process and introducing a new material to lower cost and increase effects under the condition of the same oil-proof level, and provides guarantees for the large-scale industrial production.

Description

The preparation technology of the grease proofing paperboard of a kind of food-grade
Affiliated technical field
The invention belongs to pulp technology for making paper, particularly relate to the preparation technology that a kind of surperficial grease-proof absorbs the grease proofing paperboard of food-grade of infiltration, the product of production is widely used in the packing of food and other oil-containing article behind printing box processed.
Background technology
In the prior art, resist the food-grade paperboard of grease infiltration and absorption and mainly use the oil-proofing agent coating to be processed into, the oil-proofing agent that only uses just accounts for about 1000 yuan in ton paper cost, causes product cost high.
Summary of the invention
Purpose of the present invention just is to overcome the defective of above-mentioned prior art, provides a kind of grease proofing effective, and cost is low, guarantees the preparation technology of the grease proofing paperboard of food-grade of large-scale industrial production.
The technical scheme of taking for achieving the above object is:
The preparation technology of the grease proofing paperboard of a kind of food-grade comprises with slurry, manufactures paper with pulp, and applying glue, press polish and coating is characterized in that: adopt surface sizing starch that back side of paper is carried out applying glue in applying glue and coating process.
Total resin added 3g/m of above-mentioned employing surface sizing starch double sizing 2
Above-mentioned surface sizing starch is that solid content is 13.5%～14.5%, viscosity 30-70cps, the starch gelatinization liquid of PH=7.
The present invention adopts and can replace oil-proofing agent of the prior art to come product is carried out the top sizing processing by grease proofing surface sizing starch, not only reduced product cost (can reduce by 800 yuan of left sides of ton paper cost), and grease resistance infiltration (grease proofing) is effective, in the situation of equal grease proofing grade, reach optimized production process, quote the purpose of new material cost efficiency, for large-scale industrial production provides assurance.
The specific embodiment
1, according to technological requirement surface sizing starch that can be grease proofing is used and produce with clear water to be that 13.5%～14.5% solid content carries out gelatinization according to solid content respectively, to obtain viscosity 30-70cps, PH=730-70, the starch gelatinization liquid of PH7.
2, with commodity bleaching needle-point leaf pulp (NBKP), bleached hardwood pulp (LBKP), bleached chemical thermomechanical pulp (BCTMP) and poplar machine plasma (APMP) are raw material, through suitable making beating batching, manufacture paper with pulp at 48,80/,600 4 folded net multi-cylinder paper machines, paper shifts sizing applicator top sizing (back side of paper uses the grease proofing surface sizing starch of energy) through film, afterwards through hard calender press polish, the front is carried out pigment application three times through coating machine again, after a roll-type applying glue is carried out with the grease proofing surface sizing starch of energy in the back side, after soft roll calendar press polish ornamenting, through batching, rewinding gets final product the greaseproof paper of production high-quality high-grade.
The positive coating weight 24-27g/m of paperboard of the present invention 2, back side double sizing, total resin added 3g/m 2
