Abstract

The invention provides a corrugated paperboard and a corrugated carton production process. The corrugated paperboard comprises an outer-layer paperboard and an inner-layer paperboard, wherein a firstwaterproof plate layer and a refractory plate layer are sequentially arranged on the upper surface of the outer-layer paperboard from inside to outside, a second waterproof plate layer is arranged onthe lower surface of the inner-layer paperboard, a partition plate is arranged between the outer-layer paperboard and the inner-layer paperboard, a first corrugated paper layer is bonded between the outer-layer paperboard and the partition plate through a flame-retardant glue, wave-shaped corrugated paper, a first hollow corrugated paper core and a second hollow corrugated paper core are symmetrically arranged in the first corrugated paper layer, a second corrugated paper layer is bonded between the inner-layer paperboard and the partition plate through a flame-retardant glue, corrugated paper, a third hollow corrugated paper core and a fourth hollow corrugated paper core are symmetrically arranged in the second corrugated paper layer, each hollow corrugated paper core is filled with EPE pearl wool, and the outer surfaces of each paper core are respectively coated with a smoke eliminating layer. According to the invention, the problems of poor compressive strength, poor damp-proof andwaterproof performance and poor flame-retardant and fireproof performance of the corrugated carton in the background art are solved.

Description

technical field [0001] The invention relates to the technical field of cardboard production, in particular to a production process for corrugated cardboard and corrugated boxes. Background technique [0002] Corrugated cardboard is also called corrugated cardboard. It is made of at least one layer of corrugated paper and one layer of cardboard paper, which has good elasticity and extensibility. It is mainly used in the manufacture of cartons, the sandwich of cartons and other packaging materials for fragile goods. The native straw pulp and waste paper are beaten to make base cardboard similar to yellow cardboard, which is pressed into corrugated paper during mechanical processing, and then glued to the surface of the corrugated paper with an adhesive such as sodium silicate. [0003] The corrugated paper of the corrugated cardboard in the prior art is mostly arranged in the corrugated layer horizontally in a wave shape. The cardboard with this structure has poor structural...
