Embodiment 1

[0020] The preparation method of the moisture-proof corrugated paper in this example includes the following steps: Weigh 1 kg of wood pulp and 2 kg of waste paper pulp, mix them evenly, remove impurities, add 3.5 kg of water at a temperature of 35°C to soak the pulp for 15 minutes, and then transfer it to a disperser Disperse the pulp to obtain the original pulp; add 0.75 kg of moisture-proof agent to the original pulp, and make paper; preheat the paper, use a sizing machine to apply the adhesive evenly on the surface of the paper, and pass it through a single-facer to obtain corrugated paper. Paste a layer of waxed paper on the outermost layer of corrugated paper, and finally transfer it to an oven for drying.

[0021] In this embodiment, wood pulp is prepared from wood scraps.

[0022] The moistureproof agent in this example is prepared from the following raw materials in parts by weight: 25 parts of tapioca starch, 20 parts of styrene propylene, 15 parts of crotonate, 8 par...

Embodiment 2

[0024] The preparation method of the moisture-proof corrugated paper in this example includes the following steps: take 10 kg of wood pulp and 10 kg of waste paper pulp respectively, mix them evenly, remove impurities, add 25 kg of water with a temperature of 42°C to soak the pulp for 10 minutes, and then transfer it to a disperser Break up the pulp to obtain the original pulp; add 3.8 kg of moisture-proof agent to the original pulp, and make paper; preheat the paper, use a sizing machine to apply the adhesive evenly on the surface of the paper, and pass it through a single-facer to obtain corrugated paper. Paste a layer of waxed paper on the outermost layer of corrugated paper, and finally transfer it to an oven for drying.

[0025] The wood pulp in this example is prepared from wood scraps.

[0026] The moistureproof agent in this example is prepared from the following raw materials in parts by weight: 27 parts of tapioca starch, 15 parts of styrene propylene, 13 parts of cr...

Embodiment 3

[0028] The preparation method of the moisture-proof corrugated paper in this example includes the following steps: weigh 20 kg of wood pulp and 60 kg of waste paper pulp, mix them evenly, remove impurities, add 95 kg of water at a temperature of 50°C to soak the pulp for 13 minutes, and then transfer it to a disperser Disperse the pulp to obtain the original pulp; add 11.2 kg of moisture-proof agent to the original pulp, and make paper; preheat the paper, use a sizing machine to apply the adhesive evenly on the surface of the paper, and pass it through a single-sided machine to obtain corrugated paper. Paste a layer of waxed paper on the outermost layer of corrugated paper, and finally transfer it to an oven for drying.

Abstract

The invention discloses a preparation method for moisture-proof corrugated paper. The preparation method comprises the following steps: respectively weighing wood pulp and waste paper pulp; mixing the weighed wood pulp and the waste paper pulp till the mixture is uniform; removing impurities; adding water to soak the pulp mixture; carrying out scattering to obtain virgin pulp; adding a moisture-proof agent; carrying out paper making to obtain paper; conducting preheating and sizing on the paper; treating the preheated and sized paper with a single side machine to obtain corrugated paper; pasting a piece of wax-oil paper on the outermost layer of the corrugated paper; carrying out drying. The moisture-proof agent is prepared from the following raw materials in parts by weight: 25-30 parts of tapioca, 15-20 parts of allyl benzene, 13-18 parts of butenoic acid ester, 5-8 parts of paraffin, 2-5 parts of sodium dodecyl benzene sulfonate and 1-4 parts of silicon dioxide. The moisture-proof corrugated paper is wide in raw material resource and relative low in production cost. The preparation method has the advantages that the moisture-proof agent is added in the paper making process and the wax-oil paper is pasted on the outermost layer of the corrugated paper, so that the water-proof performance and moisture-proof performance of the corrugated paper are greatly improved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for preparing moisture-proof corrugated paper. Background technique [0002] Corrugated paper is a plate made of liner paper and corrugated corrugated paper formed by processing corrugated sticks. It is generally divided into two types: single corrugated board and double corrugated board; corrugated paper is a common packaging paper. It has the advantages of reasonable structure, simple processing, light weight, low cost, and convenient storage and transportation. It has become the most extensive paper container packaging and is widely used in the field of transportation packaging. Although the existing corrugated boxes are widely used and can meet the packaging requirements of general commodities, for some special commodities, such as the packaging of fresh-keeping products such as vegetables and fruits, the casings required to be packaged can be waterproof and mois...
