Preparation method of flame-retardant corrugated board

Abstract

The invention relates to a preparation method of a flame-retardant corrugated board. The flame-retardant corrugated board is prepared through cooperation of a bottom plate, side plates, a feeding and humidifying device, a spraying device and a drying device. The preparation method of the flame-retardant corrugated board can solve the problems that the manual spraying process is tedious and preparation efficiency of the flame-retardant corrugated board is low due to the fact that when a flame-retardant coating is manually sprayed, spraying treatment needs to be conducted on the two surfaces of the corrugated board and water spraying and humidifying need to be conducted before the coating is sprayed, and can solve the problems that when an existing flame-retardant corrugated board preparation equipment is used for preparing the flame-retardant corrugated board, the flame-retardant coating is generally directly sprayed on the surface of the corrugated board, humidifying treatment is not conducted on the corrugated board before the flame-retardant coating is sprayed, so that the flame-retardant coating is difficult to completely adhere to the surface of the corrugated board, part of the position is inflammable due to lack of the flame-retardant coating, the corrugated board still has the danger of combustion and the like.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard production, in particular to a method for preparing a flame-retardant corrugated cardboard. Background technique [0002] Corrugated cardboard is a board-like object made of face paper and corrugated core paper formed by corrugated stick processing. It is generally divided into two types: single corrugated cardboard and double corrugated cardboard, and corrugated cardboard has low cost, light weight, It has the advantages of easy processing, high strength, excellent printing adaptability, convenient storage and transportation, etc. At present, the corrugated paper on the market cannot be effectively flame-retardant and fire-resistant. If it is too large, corrugated paper may burn, which greatly increases the safety of corrugated paper and is not conducive to the use of corrugated paper by users. When making corrugated cardboard, it can be sprayed with flame-retardant coating on its ...

AI Technical Summary

Problems solved by technology

[0004] (1) When spraying flame-retardant coatings on the surface of corrugated cardboard manually, it is necessary to spray the two surfaces of corrugated cardboard, and when spraying paint, it is necessary to spray water on the surface of corrugated cardboard to adjust the humidity, so that the process of manual spraying of flame-retardant coatings It is cumbersome, which in turn makes the production efficiency of flame-retardant corrugated cardboard low;

[0005] (2) Existing flame-retardant corrugated cardboard production equipment usually directly sprays flame-retardant coatings on the surface of corrugated cardboards when producing flame-retardant corrugated cardboards, and does not carry out humidity-conditioning treatment on corrugated cardboards before spraying flame-retardant coatings, thereby making It is difficult for the flame retardant coating to completely adhere to the surface of the corrugated cardboard, so that some parts are flammable due to the lack of flame retardant coating, so that the corrugated cardboard still has the danger of burning
