Corrugated board and corrugated carton production process

Abstract

The invention relates to the technical field of packaging materials, in particular to a corrugated board and a corrugated carton production process. The corrugated board comprises corrugated medium paper and two layers of outer-layer paper boards, wherein the corrugated medium paper is located between the two layers of outer-layer paper boards and fixedly connected with the outer-layer paper boards; a bendable water hose penetrates through the corrugated medium paper; a plurality of water outlet holes are formed in the water hose; fire extinguishing liquid is contained in the water hose; an easy-to-melt layer is fixedly connected to the outer wall of the water hose; fine sand is filled between the two layers of outer-layer paper boards; flame-retardant glue for bonding the fine sand into a whole is filled between the fine sand; a plurality of sets of bending assemblies arranged at intervals are arranged between the outer-layer paper boards on the two sides; the corrugated medium paper penetrates through the bending assemblies; each bending assembly comprises two flexible connecting plates and a plurality of springs; the two connecting plates are fixedly connected with the inner sides of the two layers of outer-layer paper boards; the plurality of springs are located between the two connecting plates and fixedly connect the two connecting plates; and the outer side faces of the two layers of outer-layer paper boards are fixedly connected with expansible graphite composite flame retardant layers. The corrugated carton production process has the effect of improving the flame retardance of the corrugated board.

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 cardboard boxes. Background technique [0002] The paper packaging industry is one of the fastest-growing fields in the packaging industry and has a large room for development. Corrugated cardboard is considered to be one of the most promising green packaging materials. Corrugated box is a paper container package 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") ...

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
