Description
Technical Field
The invention relates to the technical field of packaging materials, in particular to a high-strength composite single corrugated board and a preparation method thereof.
Background
In recent years, corrugated cartons stand out in the field of packaging materials by virtue of the advantages of light weight, shockproof buffering, foldability, environmental protection, recyclability and the like, but the bearing and pressure resistance of the corrugated cartons are improved by arranging multi-layer corrugated stacking in the domestic common corrugated cartons, and the corrugated cartons prepared by the structure have the advantages of large material consumption, high cost and large occupied space, so that the development trend of light weight is another challenge to the development and design of the corrugated cartons under the condition of pursuing high bearing load and high pressure resistance of the corrugated cartons. At present, adhesives are mostly compounded among various layers of corrugated cases for adhesion, the load-bearing compressive strength and the service life of corrugated boards or the corrugated cases are directly affected by the adhesive strength, the stability, the water resistance and the heat resistance of the adhesives, and the like, and starch adhesives, plant protein adhesives and the like are adhesives with development potential due to good biocompatibility, no toxicity, no odor and low price, but the problems of poor water resistance, poor corrosion resistance, insecure adhesion and the like generally exist, so that the industrial application of the adhesives is severely restricted.
Disclosure of Invention
The present invention is directed to provide a method for preparing a high-strength composite single corrugated board, and a high-strength composite single corrugated board prepared by the method, in order to solve the above-mentioned disadvantages of the prior art. The preparation method is simple, efficient, environment-friendly, nontoxic, low in cost and suitable for large-scale production, and the corrugated board prepared by the preparation method is high in compressive strength and bonding strength, stable in structure and not easy to corrugate.
The purpose of the invention is realized by the following technical scheme: a preparation method of a high-strength composite single corrugated board, which comprises a composite single corrugated paper core, and surface paper and lining paper which are bonded and fixed with the upper surface and the lower surface of the composite single corrugated paper core, comprises the following steps:
s1, preparing a corrugated paper core: preheating corrugated base paper by a preheater, wherein the preheating temperature is 103-108 ℃, and embossing the heated corrugated base paper by a corrugated roller to obtain a wavy corrugated paper core;
s2, preparing the composite single corrugated paper core: bonding the two corrugated paper cores obtained in the step S1 through an adhesive to obtain a composite single corrugated paper core;
s3, preheating surface paper and lining paper: preheating the surface paper and the lining paper respectively at the preheating temperature of 103-108 ℃;
s4, compounding corrugated boards: respectively coating a layer of adhesive on the lower surface of the surface paper and the upper surface of the lining paper preheated in the step S3, and placing the composite single corrugated paper core in the step S2 between the surface paper and the lining paper for hot pressing at the temperature of 150-;
s5, coating of a waterproof coating: and uniformly coating a layer of waterproof coating on the upper surface of the surface paper and the lower surface of the lining paper, and drying by a steam dryer to obtain the single corrugated paper core type corrugated board, wherein the drying temperature is 55-60 ℃.
In the above steps, the adhesive is a modified protein-starch composite adhesive, and the adhesive comprises the following raw materials in parts by weight: 40-60 parts of defatted soybean flour or defatted cottonseed flour, 8-15 parts of starch, 400 parts of water 150-containing materials, 1-4 parts of modifier, 4-20 parts of cross-linking agent and 0.2-0.5 part of mildew preventive. The starch is at least one of corn starch or cassava starch.
The high-strength composite single corrugated board prepared by the preparation method can reduce the thickness and the quality of the board under the condition of ensuring the compressive strength by arranging the composite single corrugated paper core bonded by the modified protein-starch composite adhesive, and the waterproof and moistureproof performances of the corrugated board are improved by arranging the surface waterproof coating. The defatted soybean flour, the defatted cotton seed flour, the corn starch and the cassava starch are natural high-molecular products which are wide in source and low in price, have the characteristics of reproducibility, easy degradation and good biocompatibility, can effectively reduce the preparation cost of the adhesive when being used for preparing the adhesive, and do not influence the recycling of waste corrugated boards or corrugated cartons. The composite adhesive is beneficial to improving the water resistance and the adhesive strength of the adhesive through the compound use of the defatted soybean powder, the defatted cotton seed powder, the corn starch or the cassava starch.
Preferably, the particle size of the defatted soybean flour or defatted cotton seed flour is 100-160 mesh.
Preferably, the modifier is a mixed solution prepared by mixing sodium dodecyl sulfate or zinc oxide with 1-3mol/L urea solution respectively, wherein the mass content of the sodium dodecyl sulfate or the zinc oxide is 3-6%.
The invention adopts the modifier to modify the soybean protein or the cottonseed protein, and the molecular structure of the protein is unfolded under the composite action of the sodium dodecyl sulfate or the zinc oxide and the urea, so that more hydrophobic groups and active components are exposed, and the water-resistant stability and the bonding strength of the binder are favorably improved.
Preferably, the crosslinking agent is at least one of polyamide epichlorohydrin, bisphenol A epoxy glycerol ether or TDE-85 epoxy resin.
According to the invention, the epoxy group in the cross-linking agent reacts with the active groups such as hydroxyl, carboxyl and amino of protein molecules to form a cross-linked network structure, and the water resistance, thermal stability and adhesive property of the adhesive can be remarkably improved by adding the cross-linking agent.
