Description
Technical Field
The invention belongs to the technical field of carton packaging, and particularly relates to a preparation method of a water-resistant environment-friendly paperboard for carton packaging.
Background
The nano barium sulfate is a novel inorganic material, has the characteristics of common barium sulfate and has new special functions, and the nano barium sulfate particles have important nano structural characteristics such as surface effect, quantum tunneling effect, size effect and the like, so that various physical and chemical characteristics of the nano barium sulfate particles are greatly different from the performances of common materials.
The paper types with the largest consumption increment in recent years are box board, white board and corrugated medium, and the sum of the three paper types accounts for more than 55 percent of the total production and total consumption of paper and board in China. Paper and paperboard packaging products always account for more than 50% of packaging industrial materials, paper products occupy more industrial markets with the advantages of good environmental protection performance and recycling, and packaging paperboards also occupy larger shares in the paper-making industry. At present, the traditional process is adopted, the flat-plate type paperboard products which are manufactured by wood pulp, waste paper pulp and the like and can be used in various industries have higher density, and if the flat-plate type paperboard products are used as filling layers and packaging materials, the problem of high density exists, and meanwhile, wood pulp resources are wasted, so that the flat-plate type paperboard products are not environment-friendly.
Open break is in the preparation and characterization of polyethylene-barium sulfate nano composite material, in the text of the book of "polyethylene-barium sulfate nano composite material", disodium Ethylene Diamine Tetraacetic Acid (EDTA) complexation method is used for one-step precipitation preparation of a nano barium sulfate solution, nano barium sulfate is prepared, surface organic modification is carried out on the surface of barium sulfate by stearic acid, and fatty acid salt molecules or ions form surface micelles through the mutual permutation and repetition between long carbon chains, so that the interaction between barium sulfate particles is reduced, the stability of the barium sulfate particles is improved, but due to the fact that the nano barium sulfate particles are very small, the dispersibility of the barium sulfate particles is poor, and agglomeration often occurs.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and the SH-1251 magnesium oxysulfate water repellent agent is added to change the internal crystal phase structure, so that the crystal phase structure becomes compact and fine, and the water resistance of the product is improved, namely the product has higher softening coefficient and stronger water resistance after being soaked in water and is more environment-friendly.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a preparation method of a waterproof environment-friendly paperboard for carton packaging comprises the following steps:
(1) after magnesium sulfate and magnesium oxide are combined and changed through the effect of an SH-2152 magnesium oxysulfate modifier, a magnesium oxysulfate product generates a basic magnesium oxysulfate cement phase, the crystal is loose, water can easily permeate to be corroded by the water, and the magnesium oxysulfate product shows that the magnesium oxysulfate product is not water-resistant;
(2) adding an SH-1251 magnesium oxysulfate water repellent agent in the step (1), changing the internal crystalline phase structure to make the crystal compact and fine, and improving the water resistance of the product, namely the product has higher softening coefficient and stronger water resistance after being soaked in water;
(3) the SH-2151 magnesium oxysulfate water-resistant agent has a remarkable effect when the mixing amount is 0.5% of the magnesium oxide;
(4) uniformly mixing 60-80 parts by weight of wood fiber pulp subjected to impurity removal and filtration treatment and plant fiber pulp in a pulping machine, adding 30-40 parts by weight of oxidized starch solution into the mixed pulp, uniformly mixing, adding 0.02-0.1 part by weight of amylase, stirring for 2-4 hours, then adding a nano barium sulfate mixture, inputting the paper board pulp and a crystal added with an SH-1251 magnesium oxysulfate water-resistant agent into a paper board forming machine for processing, performing dehydration forming, then performing drying for 2 times until the water content of the paper board is 2-5%, standing for 12 hours, polishing, and cutting and forming to obtain the water-resistant environment-friendly paper board for carton packaging.
Compared with the prior art, the SH-1251 magnesium oxysulfate water repellent agent is added to change the internal crystal phase structure, so that the crystal phase structure becomes compact and fine, and the water resistance of the product is improved, namely the product has higher softening coefficient after being soaked in water, stronger water resistance and more environmental protection.
