Composite corrugated paper and preparation method thereof

Abstract

The invention relates to the technical field of corrugated paper, in particular to composite corrugated paper and a preparation method thereof. The composite corrugated paper comprises first surface paper, an antibacterial layer, a reinforcing layer, corrugated core paper, a fiber layer, a waterproof layer and second surface paper which are sequentially attached, and the upper surface of the reinforcing layer and the lower surface of the fiber layer are each coated with a composite adhesive layer. A composite adhesive is prepared from the following raw materials in parts by weight: 10-20 partsof modified alkyd resin, 0.1-2.0 parts of azo initiator, 1-5 parts of phenolic compound, 10-15 parts of deionized water, 1-5 parts of polyvinyl alcohol, 10-20 parts of rice hull fiber, 20-30 parts ofepoxy resin, 1-3 parts of nano SiO2, 8-12 parts of chitosan, 1-5 parts of plasticizer, 0.1-3.0 parts of curing agent, 0.1-3.0 parts of antioxidant, 0.1-1.0 part of citric acid, 1-5 parts of a fillerand 15-25 part of starch. The composite corrugated paper provided by the invention has good strength and mildew-proof and antibacterial effects, and is long in service life.

Description

technical field [0001] The invention relates to the technical field of corrugated paper, in particular to a composite corrugated paper and a preparation method thereof. Background technique [0002] In all kinds of packaging of industrial products, corrugated paper has good anti-deformation characteristics, so the packaging box pasted by corrugated paper has the strength of anti-deformation, which can effectively avoid the damage of corrugated paper and cause the objects to be scattered on the ground. As the most important and widely used packaging material, cardboard has the advantages of light weight, low cost, easy processing, convenient storage and transportation, which is not available in wood packaging and metal packaging, while its U, V, UV and other flute The shape structure also greatly improves the compression and burst resistance of the carton, but its disadvantages are: the strength and impact resistance of the traditional corrugated cardboard are not high during...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a composite corrugated paper, which adopts the first face paper, antibacterial layer, reinforcement layer, corrugated core paper, fiber layer, waterproof The multi-layer structure of the first layer and the second surface paper makes the composite corrugated paper have good strength, impact resistance, anti-mildew and antibacterial effect, the fiber layer and the reinforcement layer, and the composite adhesive provide double protection for the corrugated paper, so that the corrugated paper has good The advantages of high strength, impact resistance and not easy to open glue. The cartons made of this corrugated paper are not easy to disintegrate in a humid environment, not easy to be moldy and insect-eaten, and the shipped items are extremely stable, which prolongs the service life of corrugated paper. It avoids the problem that the anti-deformation structure is single, resulting in poor anti-deformation effect
