High-strength corrugated board and production process thereof

Abstract

The invention discloses a high-strength corrugated board and a production process thereof. The corrugated board comprises a high-density grey board paper core, sawtooth paper sheets are fixedly connected to the top and the bottom of the high-density grey board paper core, paper tubes are fixedly connected to the interiors of the sawtooth paper sheets, a corrugated body is fixedly connected to the surfaces of the sawtooth paper sheets, and the surface of the corrugated body is fixedly connected with surface paper. The overall strength of the corrugated board is improved through the high-density grey board paper core, the contact area between the corrugated bodies and the high-density grey board paper core is increased through the sawtooth paper pieces, the supporting strength of the corrugated bodies is improved, and finally the compression resistance and puncture resistance of the corrugated board are improved through the reinforcing coatings by means of the corrugated bodies distributed longitudinally and transversely; therefore, the corrugated board has the advantage of high strength, and the problems that an existing corrugated board is mainly supported by internal corrugations in the using process, and bending frequently occurs due to the fact that the contact area between the corrugations and the board is smaller and the supporting strength is smaller are solved.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard, in particular to a high-strength corrugated cardboard and a production process thereof. Background technique [0002] Corrugated cardboard is a multi-layer adhesive body. It is composed of at least one layer of corrugated core paper interlayer and one layer of cardboard. During the use of existing corrugated cardboard, it is mainly supported by the inner corrugations. Due to the contact area between corrugated and cardboard Smaller, the support strength is smaller, and bending often occurs. Contents of the invention [0003] In order to solve the problems raised in the above-mentioned background technology, the purpose of the present invention is to provide a high-strength corrugated cardboard and its production process, which has the advantages of high strength and solves the problem that the existing corrugated cardboard is mainly used by the internal Corrugated corrugated suppo...

Problems solved by technology

[0003] In order to solve the problems raised in the above-mentioned background technology, the object of the present invention is to provide a high-strength corrugated cardboard and its production process, which has the advantages of high strength and solves the problem of the existing corrugated cardboard being used mainly by internal Corrugated corrugated support, because the contact area between corrugated and cardboard is small, the support strength is small, often bending problems
