Description

A kind of preparation method of corrugated paper
Technical field
The present invention relates to paper technology, particularly a kind of preparation method of corrugated paper.
Background technology
Corrugated board is applied to transportation and packing field, has low light weight, cost, easy processing, easy to storing and transport Advantage, this is not available for timber packaging and mental package.Corrugated paper is mounted by both facial tissue and core paper and formed, and core paper is general To be wavy, its function and intensity are divided by the difference of stupefied shape grade.As a kind of excellent packaging material, corrugated paper With the mechanical performance such as light, resistance to puncture, shockproof, easy processing shaping, and good decoration printing adaptability, can circulate again Utilize, it is environmentally safe the advantages that, therefore favored be subject to modern society, its use scope is more and more wider, and development speed is also got over Come faster.With the extensive use of corrugated paper, requirement of the people to corrugated paper is also higher and higher.
The content of the invention
It is a primary object of the present invention to provide a kind of preparation side of higher, the more environmentally friendly corrugated paper of overall construction intensity Method.
To achieve the above objectives, the technical solution adopted by the present invention is：A kind of preparation method of corrugated paper, including following step Suddenly：
Step 1: choosing paper making raw material, add water to carry out bubble slurry, put into pulper and crush, paper making raw material is dissociated into fibre Dimension, and carry out filtering screening and remove crude fibre and impurity, it is beaten and magma is made；
Step 2: toward 10-15 parts of modifying agent of addition in 100 parts of magma by weight, it is sufficiently stirred, then goes to remove water Point, obtain the copy paper that moisture content is 10-20% and starch, wherein the modifying agent includes 35-50 parts of polyacrylamide by weight, 20-25 parts of graphenes, 10-15 parts of carborundum, 1-5 parts of diatomite, 1-5 parts of boric acid ester couplers, the anti-blushing agent is by weight Include 35-50 parts of polypropylene, 20-25 parts of calcium oxide, 10-15 parts of paraffin, 1-5 parts of silica, 1-5 parts of polyvinyl alcohol and 0.5-1 parts of rare earth elements；
Obtained paper of manufacturing paper with pulp is carried out by paper machine Step 3: starching copy paper, is then preheated the paper, using sizing Adhesive is uniformly applied to paper surface by machine, wherein adhesive include by weight 10-15 parts of vinylacetates, 10-15 parts Melamine, 5-10 parts of water-based terpene phenolic resin lotions, 70-80 parts of water；
Step 4: corrugated paper semi-finished product of the surface after sized are put into drying cylinder, temperature is adjusted to 120 DEG C~125 DEG C, moisture content 2%~4%, be placed on indoor standing 24 it is small when after, further take out be placed at aeration-drying place 24 it is small when, you can Obtain highly intensified corrugated paper.
The paper making raw material includes 70-80 parts of sawdust, 10-20 parts of agricultural crop straw, 5-15 parts of bagasse slurry by weight And 5-10 parts of corn syrup.
The preparation method of the modifying agent is first by 35-50 parts of polyacrylamide, 20-25 parts of graphenes, 10-15 parts of carbon SiClx, 1-5 parts of diatomite are uniformly mixed, then heat while stirring, and heating-up temperature is 200-250 DEG C, when being cooled to 100 DEG C 1-5 parts of boric acid ester couplers are put into, keep the temperature 30min.
The preparation method of the anti-blushing agent is first the 20-25 parts of calcium oxide by 35-50 parts of polypropylene, 10-15 parts of paraffin, 1-5 parts of silica and 0.5-1 parts of rare earth elements are uniformly mixed, and are then heated while stirring, heating-up temperature is 200-250 DEG C, 1-5 parts of polyvinyl alcohol are put into when being cooled to 100 DEG C, keep the temperature 30min.
The preparation method of the adhesive be by 10-15 parts of vinylacetates, 10-15 parts of melamines, 5-10 parts it is water-based Terpene phenolic resin lotion, 70-80 part water, 50-60 DEG C is heated to after stirring evenly makes each component all dissolve, and treats temperature nature It is reduced to room temperature.
Polyacrylamide in the modifying agent, greatly strengthen the burst index and ring crush index of corrugated paper so that this Corrugated paper possesses higher intensity, improves the service life of corrugated case.Graphene and carborundum can improve corrugated paper Physical strength, improves consolidation sense and the surface nature of cardboard entirety, improves paper density and horizontal ring crush index, strengthens at the same time Its dimensional stability.Diatomite has fine and smooth, loose, light, porous, water imbibition and the strong property of permeability, can be by carborundum Absorption is on surface, so as to reach more preferable combination, boric acid ester coupler is then used to polyacrylamide and graphene being coupled Effect.The properties of corrugated paper made from production method using the present invention and material index comply fully with each of corrugated paper Item requires.
Polypropylene and paraffin in the anti-blushing agent is as organic anti-blushing agent, and calcium oxide is inorganic anti-blushing agent, silica For separating directly contacting for outer vapor and corrugated paper, polyvinyl alcohol be then used to improving organic anti-blushing agent and inorganic anti-blushing agent it Between connection, promote both synergistic effects.Rare earth element then promotes the effect of moisture-proof active ingredient to play, and it is anti-finally to improve it Tidal energy power.
The adhesive is aqueous binder, and wherein vinylacetate and melamine are then used to improve adhesion strength, water Property terpene phenolic resin lotion be used to improve the various surface tension formed between phases in emulsion, be allowed to be formed uniform and stable The material of dispersion or emulsion.
The paper making raw material includes sawdust, agricultural crop straw, bagasse slurry and corn syrup, effectively utilizes every profession and trade Caused discarded object, adapts to energy conservation and environmental protection and circular economy spirit that the whole society advocates, while corn syrup is that have corn Stalk is obtained by autoclaving, naturally environmentally friendly.
A kind of preparation method for corrugated paper that the present invention obtains, its technique effect are modified by being added in paper making raw material Agent, greatly strengthen the burst index and ring crush index of corrugated paper so that this corrugated paper possesses higher intensity, improves corrugation The service life of carton.Anti-blushing agent is added, the humidity resistance of corrugated paper is enhanced, makes its side under 85% state of relative humidity The common cardboard of pressure intensity ratio improves 30% or so.In addition the adhesive of independent research is used, then so that between corrugated paper Adhesion strength it is stronger, further improve the intensity of corrugated paper.
