High-strength flame-retardant corrugated board

Abstract

The invention belongs to the technical field of corrugated boards, and particularly relates to a high-strength flame-retardant corrugated board which comprises outer boards, a clamping board, corrugated core layers and air storage film bags; the corrugated core layers are symmetrically installed on the side walls of the two sides of the clamping board; the outer boards are symmetrically installedon the side walls of the corrugated core layers, the outer side walls of the outer boards are coated with a flame-retardant paint, and a plurality of vent holes are formed in the outer boards; the outer boards, the clamping board, the corrugated core layers and the gas storage film bags are matched, so that the content of carbon dioxide gas around the corrugated board can be increased when the corrugated board encounters high temperature; the oxygen content of the outer side surfaces of the corrugated board is reduced, the combustion probability of the corrugated board is further reduced, theflame retardant effect is achieved, when the gas storage film bag does not explode, the gas storage film bags can play a supporting role between the side walls of the corrugated core layers, and therefore the use strength of the corrugated board is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of corrugated cardboard, in particular to a high-strength flame-retardant corrugated cardboard. Background technique [0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper interlayer (commonly known as "pit sheet", "corrugated paper", "corrugated core paper", "corrugated core", "corrugated base paper") and a layer Cardboard (also known as "boxboard", "boxboard"). It has high mechanical strength and can withstand bumps and falls during handling. The actual performance of a corrugated box depends on three factors: the properties of the medium and paperboard and the construction of the box itself. Corrugated cardboard is also called corrugated cardboard. It is made of at least one layer of corrugated paper and a layer of cardboard (also called cardboard), which has good elasticity and extensibility. It is mainly used in the manufacture of ...

AI Technical Summary

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, when a packaging box made of corrugated cardboard encounters a fire, since corrugated cardboard is a flammable item, the items in the packaging box will be seriously affected by the fire, resulting in partial damage to the item or even burnt, increasing the loss suffered by the user when encountering a fire; the present invention proposes a high-strength flame-retardant corrugated cardboard
