A kind of corrugated cardboard and corrugated box production process

Abstract

The present application relates to the technical field of packaging materials, in particular to a production process of corrugated cardboard and corrugated boxes, which includes corrugated core paper and two outer layers of cardboard, wherein the corrugated core paper is located between the two outer layers of cardboard and is fixed to the outer layer of cardboard. The corrugated core paper is penetrated by a flexible water pipe that can be bent. The soft water pipe is provided with a plurality of water outlet holes. The soft water pipe is filled with fire extinguishing liquid. The outer wall of the soft water pipe is fixed with a fusible layer. The space is filled with fine sand, and the fine sand is filled with flame retardant glue that bonds the fine sand into one. Multiple sets of spaced bending components are arranged between the outer cardboards on both sides, and the corrugated core paper runs through the bending components. The bending assembly includes two flexible connecting plates and a plurality of springs. The two connecting plates are both fixed to the inner side of the two layers of outer cardboard, and the plurality of springs are located between the two connecting plates and fixedly connect the two connecting plates. An expandable graphite composite flame retardant layer is fixed on the outer side of the outer cardboard, and the present application has the effect of improving the flame retardancy of the corrugated cardboard.

Description

technical field [0001] The present application relates to the technical field of packaging materials, in particular to a production process of corrugated cardboard and corrugated boxes. Background technique [0002] The paper packaging industry is one of the fastest developing areas in the packaging industry, and has a large space for development. Corrugated cardboard is considered to be one of the most promising green packaging materials. Corrugated carton is a paper container packaging made of corrugated cardboard, which is widely used in transportation packaging. For more than 100 years, corrugated boxes have become the main packaging form of transportation packaging and are the most widely used packaging materials in the world. [0003] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper (commonly known as "pit sheet", "corrugated paper", "corrugated core paper", "corrugated core", "corrugated base paper") a...

AI Technical Summary

Problems solved by technology

[0004] Regarding the related technologies mentioned above, the inventor believes that there are the following defects: when transporting flammable, explosive and other dangerous products, the related corrugated cardboard has poor flame retardancy, which limits the application of corrugated cardboard boxes in some special scenarios. For functional paper packaging with fire and flame retardant requirements, corrugated cardboard needs to be treated with flame retardant to meet fire safety standards
