Waterproof stain-resistant corrugated carton and preparation process thereof

Abstract

The invention discloses a waterproof stain-resistant corrugated carton and a preparation process thereof. The corrugated carton is formed by bonding surface paper, inner paper, core paper and corrugated paper processed into corrugated corrugations. The surface paper, the inner paper, the core paper and the corrugated paper processed into corrugated corrugations are each coated with a layer of waterproof stain-resistant emulsion before being bonded to form a layer of waterproof stain-resistant film; the waterproof stain-resistant emulsion comprises the raw materials in percentage by mass: 8 to12 percent of a waterproof stain-resistant agent, 25 to 30 percent of methyl acrylate, 5 to 8 percent of methyl methacrylate, 10 to 15 percent of ethyl acrylate, 3 to 5 percent of an initiator, 0.5 to1.2 percent of an emulsifier and the balance being deionized water; then the waterproof stain-resistant corrugated carton is obtained through bonding, pressing, cutting and binding, has good waterproof, antibacterial and stain-resistant properties, and is relatively high in practicability.

Description

technical field [0001] The invention belongs to the technical field of packaging, and in particular relates to a waterproof and stain-resistant corrugated box and a preparation process thereof. Background technique [0002] As an indispensable packaging container in production and life, corrugated boxes are widely used in the transportation and packaging of various industries such as food, household appliances, textiles, food industry, and daily chemicals. With the improvement of people's consumption level, not only the demand for cartons has increased, but also higher requirements have been put forward for the appearance and functionality of cartons. [0003] Corrugated cardboard is a kind of paper composite board, which is a non-metallic interlayer material with visco-elasticity and plasticity. It is made of corrugated corrugated core paper and inner and outer paper. Pads, paper corner protectors, display stands, paper furniture, paper toys, lightweight building materials...

AI Technical Summary

Problems solved by technology

Due to the material of the corrugated box, the surface of the corrugated box is extremely easy to absorb water and adhere to bacteria and mold. After the corrugated box absorbs water and gets damp, the bacteria and mold will multiply on the corrugated box to produce a large number of bacterial and mildew spots, and the waterproof and stain resistance performance is poor. It has dropped sharply, and it may even become unusable. It is easy to be infected with bacteria when in contact with moldy cartons, which is not good for your health.
