Abstract

The invention provides a preparation method of corrugated paper. The preparation method comprises the following steps that S1, plant fibers are subjected to alkali liquor infiltration treatment, and cut into short plant fibers; S2, the short plant fibers are washed, dipping treatment is carried out by adopting an ethylenediamine solution, and washing and drying are carried out to obtain a treatedplant fiber raw material; and S3, the treated plant fiber raw material, an adhesive, inorganic oxidized particles and an auxiliary agent are mixed and stirred, are subjected to corrugation pressing and molding to obtain the corrugated paper. Mechanical problems such as product strength are solved from mixing of preparation raw materials of the corrugated paper, strong impact force is buffered by designing specific progressive impact deformation resistance of the paper board, and the problem that the paper board is prevented from being damaged due to impact is solved in cooperation with the high-strength of the corrugated paper.

Description

technical field [0001] The present invention relates to the production technology of corrugated paper, and more particularly relates to a preparation method of corrugated paper and corrugated board. Background technique [0002] Corrugated paper is a plate-like object formed by bonding corrugated corrugated paper formed by corrugated stick processing. 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 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 goods from vibration or impact during storage and transportation. Three-layer and five-layer corrugated cardboard is used in the production of corrugated boxes. common. The packaging of many commodities is simple and exquisite through three or five layers...
