Embodiment Construction

[0028] A method for producing recycled cardboard paper, comprising a paper body, which sequentially includes a surface layer, a core layer and a bottom layer from top to bottom, and the surface layer includes the following components: Mariinski unbleached kraft softwood 40-60% of pulp and 40-60% of Jinxing wood pulp, the core layer and the bottom layer all include the following components: 40-60% of old corrugated boxes and 40-60% of domestic waste paper, including the following steps in turn:

[0029] Step 1: Proportion of surface layer raw materials: Mariinsky unbleached kraft softwood pulp and Venus wood pulp are mixed to make surface layer raw material wood pulp;

[0030] Step 2: Disintegration for the first time: put the surface layer raw material wood pulp proportioned in step 1 into the crusher, and add 180-200PPm of biological enzymes into the crusher to disintegrate to form a slurry with a concentration of 4.5%;

[0031] Step 3: refining for the first time: the slurry...

Abstract

The invention relates to a production method of recycled case board paper. The recycled case board paper comprises a paper body, wherein the paper body sequentially comprises a face layer, a core layer and a bottom layer from top to bottom. The production method sequentially comprises the following steps of face layer raw material preparation in proportion, first time of pulping, first time of defibrination, core layer and bottom layer preparation in proportion, second time of pulping, second time of defibrination, bottom layer pulp preparation, core layer pulp preparation, mesh forming, squeezing, first time of drying, aspersive application on the surface, second time of drying, press-polishing and rolling and slitting. The production method has the advantages that a paper anti-burst agent is added in mesh forming and increases the contact area with fiber, more hydrogen bonds are formed for bonding, the bonding power of the fiber is improved, fiber cutinization is retarded, the folding endurance of the case board paper is improved, it is ensured that no shedding occurs on the surface after the paper is reused for multiple times, accordingly the damage rate of a smokebox is reduced, the one-time cyclic use rate of the smokebox is improved, it is ensured that the strength of paper cartons is not reduced and the cartons are not damaged after the paper is reused for multiple times, and secondary use is not affected.

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...
