Abstract

The invention discloses a corrugated board. The corrugated board comprises a paperboard matrix. The paperboard matrix comprises the following components in parts by weight: 100 parts of paper pulp, 4-6 parts of polyglycolic acid, 2-3 parts of cationic polyacrylamide, 5-10 parts of oxidized alkylamine polyoxyethylene ether, 1-2 parts of chitosan, 1-2 parts of thickener and 20-30 parts of deionizedwater. A thermoplastic elastomer is arranged on the surface of the paperboard matrix; a nanometer titanium dioxide sol layer is arranged on the thermoplastic elastomer; the thermoplastic elastomer iscompounded on the paperboard matrix by a hot pressing technology; and the thermoplastic elastomer and the nanometer titanium dioxide sol layer are bonded by PU (polyurethane) glue.

Description

technical field [0001] The invention relates to the field of cardboard, in particular to a corrugated cardboard. Background technique [0002] Corrugated board is a corrugated board formed by liner board and corrugated sticks. It is generally divided into two types: single corrugated board and double corrugated board. According to the size of the corrugated board, it is divided into five types: A, B, C, E, and F. Types of. The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. [0003] The protection of packaging materials to the quality of the contents is one of the main functions of packaging, and the inner packaging plays a vital role in the protection of goods. [0004] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated paper core...
