Production method of recycled case board paper

Abstract

The invention relates to a production method of recycled and reused containerboard paper, which comprises a paper body, which sequentially includes a surface layer, a core layer and a bottom layer from top to bottom, and includes the following steps in sequence: the ratio of raw materials for the surface layer, the first crushing solution, the first refining, the ratio of core layer and bottom layer raw materials, the second crushing, the second refining, bottom layer pulp preparation, core layer pulp preparation, wire forming, pressing, first drying, Surface sizing, second drying, calendering, coiling and cutting; the advantages of the present invention: by adding paper anti-burst agent in the forming of the wire part, the contact area between the paper anti-burst agent and the fiber is enhanced to form more hydrogen Bonding, improving the bonding force between fibers, slowing down the horniness of fibers, improving the folding resistance of the cardboard paper, ensuring that the surface does not peel after repeated reuse, thereby reducing the damage rate of the cigarette box and improving the single cycle of the cigarette box Utilization rate, and ensure that the strength of the carton will not decrease or be damaged after repeated reuse, and will not affect the secondary use.

Description

technical field [0001] The invention relates to a method for producing recycled cardboard paper. Background technique [0002] In recent years, the national cigarette production and sales have been basically stable at about 50 million boxes, and about 250 million cigarette boxes are needed, which is a huge number. In order to thoroughly implement the spirit of the 18th National Congress of the Communist Party of China, accelerate the transformation of the development mode of the tobacco industry, and build a circular tobacco industry The logistics system further reduces costs, reduces waste, and saves resources. The State Tobacco Monopoly Administration issues an annual target task for the recycling of cigarette packaging boxes in the industry for the next year, and promotes the recycling of cigarette packaging boxes among industrial and commercial enterprises. [0003] Every time the smoke box is recycled, from a small point of view, it means that the purchase is reduced, t...
