Embodiment 1

[0056] A production process of a high-strength anti-deformation corrugated box, comprising the following steps:

[0057] A: Raw material pretreatment: Put waste paper, bamboo stalks and wheat straws into a pulverizer to process into scraps, then dissociate the scraps into fibers, and then filter and screen to remove impurities in the fibers;

[0058] B: Beating: Pour the crushed fiber into the refiner, add silica, vinyl acetate, polyethylene fiber and water, the ratio of silica, vinyl acetate, polyethylene fiber is 1:1: 5. Then beat the pulp to obtain a uniformly mixed pulp, and then place the pulp for 0.5 hours, and the concentration of the pulp is 5-10%;

[0059] C: Enzymolysis: Cool the fiber slurry to 20°C, add amylase and acid-base regulator, the enzyme activity of amylase is 1.8 million U / g, the enzymolysis treatment time is 1h, and the pH of the slurry is controlled at 4 ;

[0060] D: Preparation of paper: use a paper machine to dehydrate the fiber slurry and press it...

Abstract

The invention discloses a high-strength anti-deformation corrugated paper box, and relates to technical fields related to corrugated paper boxes. The paper box comprises a bottom plate, side plates are fixedly connected on the bottom plate, a top plate is fixedly connected to the top ends of the side plates, a support is arranged between the bottom plate and the side plates, and the bottom plate and the side plates are fixedly connected through the support. First reinforcing ribs are fixedly connected between the bottom plate and the side plates, and second reinforcing ribs are fixedly connected between the side plates and the top plate. The invention further discloses a production technology of the high-strength anti-deformation corrugated paper box. The production technology comprises the following steps of A, raw material preprocessing; B, pulping; C, enzymolysis; D, paper preparation, E, heat treatment; F, gluing; G, corrugated paper board preparation; H, line pressing; I, printing; J, assembling. Through the arrangement of the support, the first reinforcing ribs and the second reinforcing ribs, the compression resistance of the eight corners of the corrugated paper box can beenhanced, the corrugated paper box is prevented from deforming, and the corrugated paper box is simple in structure, low in manufacturing cost and long in service life.

Description

technical field [0001] The invention relates to the related technical field of corrugated cartons, in particular to a high-strength anti-deformation corrugated carton and a production process. Background technique [0002] Corrugated cardboard is die-cut, creasing, nailed or glued to make corrugated boxes. Corrugated carton is the most widely used packaging product, and its consumption has always been the first among all kinds of packaging products. Including calcium plastic corrugated box. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transportation packaging containers due to their superior performance and good processing performance, and have become the main force of transportation packaging. In addition to protecting the goods and facilitating storage and transportation, it also plays the role of beautifying and promoting the goods. [0003] With the continuous increase of market demand, the scale of corrugated box produ...
