Embodiment 1

[0015] The specific preparation process of the flame-retardant corrugated cardboard mentioned in the present invention is as follows:

[0016] 1) Prepare the upper surface layer and the lower surface layer. The preparation process of the upper surface layer and the lower surface layer includes: selecting raw materials, preparing pulp, papermaking, and finishing;

[0017] The pulp preparation process is as follows: First, pour the slurry into the mixing tank, add 7.5 times the volume of the slurry in water, and stir evenly. The temperature of the mixing tank is controlled at 25°C-38°C; Auxiliary, the interval time is about 12 minutes, keep the temperature of the mixing bucket and continue to stir; then, the temperature of the mixing bucket is raised to 35°C-48°C, and stir fully; finally, pour in a certain amount of water, stir well, and the temperature of the mixing barrel is maintained at 30 ℃, the prepared pulp concentration is about 0.8%-0.85%;

[0018] The papermaking oper...

Abstract

The invention discloses a corrugated board and a manufacturing method thereof. The key point is that the manufacturing method comprises the steps of manufacturing an upper surface layer and a lower surface layer of a paperboard, manufacturing a middle corrugated layer, bonding and curing, cutting, soaking in a flame retardant and drying. The invention provides a manufacturing process for the corrugated paperboard with flame retardant characteristics. The manufacturing method is reasonable in arrangement, is simple and convenient in process, and is moderate in cost; the manufactured corrugatedboard is high in interlayer bonding strength, is stable in performance, has the advantages of being flame-retardant, fireproof, safe, reliable and the like, achieves a great effect in improving safetyof packaged objects, and has a wide market prospect in popularization of a flame-retardant packaging material.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a corrugated board and a manufacturing method thereof. Background technique [0002] Corrugated cardboard is made by bonding face paper, inner paper, core paper and corrugated paper processed into corrugated corrugated. According to the needs of commodity packaging, corrugated cardboard can be processed into single-sided corrugated cardboard, three-layer corrugated cardboard, five-layer, seven-layer, eleven-layer and other corrugated cardboard. Single-sided corrugated cardboard is generally used as a lining protective layer for commodity packaging or to make lightweight card grids and pads to protect products from vibration or impact during storage and transportation. Three-layer and five-layer corrugated cardboard are used in the production of corrugated boxes. common. The packaging of many commodities is simple and exquisitely packaged by three or five...
