Problems solved by technology

[0003] With the wide application of corrugated boxes, the packaging industry has higher and higher quality requirements for corrugated paper: corrugated paper is required to have a strong burst index and ring pressure index, while the existing corrugated paper has a relatively high burst index and ring pressure index. Weak, resulting in corrugated box packaging or easy to rot during transportation
[0004] On the other hand, adhesives are an important material in the production process of corrugated boxes. Almost all quality indicators of cardboard and cartons are related to adhesives. Resistance, the existing adhesives are difficult to meet the requirements of high strength performance and environmental protection recycling

Abstract

The invention provides a high-strength wear-resistant corrugated carton packaging material, and belongs to the field of packaging materials, and a preparation method of the high-strength wear-resistant corrugated carton packaging material comprises the following steps: carrying out coprecipitation on amino cellulose and paper pulp by using an alkali-urea water system to obtain modified paper pulp, carrying out dehydration, pulp distribution and drying on the modified paper pulp to obtain corrugating base paper, carrying out rolling and glue spraying reinforcement on the corrugating base paper, and carrying out drying to obtain the high-strength wear-resistant corrugated carton packaging material. And drying together with corrugated base paper, and then bonding through a binder to obtain the corrugated carton packaging material. According to the invention, amino cellulose is added through a coprecipitation method, so that the amino cellulose and paper pulp fibers are fully entangled and interpenetrated, the strength and wear resistance of the product are improved, and the mechanical strength of the corrugated carton is further improved by adding graphene.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a high-strength and wear-resistant corrugated box packaging material. Background technique [0002] Corrugated paper is a common packaging paper. Because of its reasonable structure, simple processing, light weight, low cost, and easy storage and transportation, it has become the most extensive paper container packaging and is widely used in the field of transportation packaging. Corrugated paper is a plate made of liner paper and corrugated corrugated paper formed by processing corrugated sticks. It is generally divided into two types: single corrugated board and double corrugated board. [0003] With the wide application of corrugated boxes, the packaging industry has higher and higher quality requirements for corrugated paper: corrugated paper is required to have a strong burst index and ring pressure index, while the existing corrugated paper has a relatively high burst ind...
