[0002] At present, corrugated cardboard boxes have been widely used for packaging and transportation of various items. It is easy to change, can be printed with high quality, and can be used as a renewable resource after recycling. Therefore, it is used more and more widely. The strength and impact resistance of the packaged corrugated paper is not enough during use, and it is easy to be damaged. At the same time, the anti-deformation structure is single, resulting in poor anti-deformation effect, affecting its service life and application range, and cannot play a good role in protecting the packaged items. , at the same time, the existing corrugated paper has poor flame retardancy, and there are potential safety hazards in use

Abstract
The invention relates to the technical field of corrugated paper, particularly to high-strength impact-resistant composite corrugated paper and a preparation method thereof. The high-strength impact-resistant composite corrugated paper comprises an outer surface paper layer, a middle filling layer, a core surface paper layer, a wavy core layer and an inner surface paper layer which are sequentially arranged from top to bottom, wherein every two adjacent layers are bonded through an adhesive, the middle filling layer is prepared from the following raw materials in parts by weight: 50-60 parts of polyvinyl chloride, 22-30 parts of cropstrawpowder, 16-24 parts of polystyrene resin, 8-14 parts of an ethylene-vinyl acetatecopolymer, 15-21 parts of inorganic filler, 3-6 parts of aluminum hydroxide, 3-5 parts of a coupling agent, 2-4 parts of an antioxidant, 2-5 parts of a foaming agent, 2-4 parts of a lubricating agent and 6-9 parts of hyperbranched epoxy resin. According to the compositecorrugated paper, the middle filling layer and the other layers are arranged in the composite corrugated paper, so that the impact resistance and strength of the corrugated paper layer can be improved, the composite corrugated paper has good shock resistance and buffering performance, and packaged objects can be well protected.
Description
technical field [0001] The invention relates to the technical field of corrugated paper, in particular to a high-strength impact-resistant composite corrugated paper and a preparation method thereof. Background technique [0002] At present, packing boxes made of corrugated cardboard have been widely used in the packaging and transportation of various items. Because of their light weight, foldability, low cost, green environmental protection, easy to change specifications, high-quality printing, and can be used as recyclables after recycling Renewable resources, therefore, are used more and more widely. However, when the existing corrugated cardboard is used for packaging items, in the process of transportation and handling, the corrugated cardboard used as the outer packaging of the items has insufficient strength and impact resistance during use and is easily damaged. At the same time, the anti-deformation structure is single, resulting in poor anti-deformation effect, aff...
