Nano-coated waterproof and anti-fouling corrugated carton

Abstract

The invention discloses a nano-coated waterproof and anti-fouling corrugated carton. The nano-coated waterproof and anti-fouling corrugated carton comprises a corrugated paperboard. The corrugated paperboard is sequentially composed of surface paper, corrugated paper and inner paper from outside to inside. The surface of the surface paper and the surface of the inner paper are coated with nano waterproof and anti-fouling paint. The paint is prepared from, by weight, 50-60 parts of epoxy resin, 10-20 parts of nano titanium dioxide, 20-30 parts of curing agents, 5-10 parts of active diluents, 1-2 parts of dispersing agents and 10-15 parts of organic solvents. Gaps of V-shaped structures of the corrugated paper are filled with drying agents. According to the nano-coated waterproof and anti-fouling corrugated carton, a plurality of waterproof layers are adopted, the surface paper and the inner paper are both coated with the nano waterproof and anti-fouling paint, and the nano titanium dioxide which is highly hydrophilic and oleophylic is added into the paint, so that the waterproof and anti-fouling capacity of the paperboard can be improved; and the V-shaped wavy structures of the corrugated paper are filled with the molecular sieve drying agents, and thus the waterproof capacity of the paperboard is further improved.

Description

technical field [0001] The invention belongs to the technical field of carton production, and relates to a corrugated carton, in particular to a nano-coated waterproof and antifouling corrugated carton. Background technique [0002] Corrugated cartons have become the main packaging containers for paper products due to their excellent cushioning protection performance, good printing display and environmental protection advantages, and have been widely used in the transportation of various commodities. At present, the commonly used corrugated cartons on the market are face paper, corrugated paper and inner paper from outside to inside, and the corrugated paper has a "V"-shaped wave structure. [0003] Because the main component of corrugated paper boxes is paper fiber with strong water absorption, it is easy to be affected by moisture and impregnated with oil. In order to meet the requirements of different products, various carton products with special properties, such as wate...

Problems solved by technology

[0004] In order to solve the problem of weak waterproof and antifouling effects of corrugated boxes, the present invention provides a nano-coated waterproof and antifouling corrugated box, which has multiple waterproof layers, the surface paper and inner paper are coated with waterproof paint, and the corrugated paper The "V" wave structure is filled with molecular sieve desiccant, and the nano material TiO is added to the coating. 2 ,Because the surface of the nanomaterial has superhydrophilicity and superlipophilicity, the surface has the characteristics of anti-fog, anti-fouling, easy-drying, etc., and is coated with nano-TiO 2 The surface of the coating has a high degree of self-cleaning effect. Once the surface is polluted by oil, a small amount of pollutants attached will be automatically removed from the TiO2 under the action of external wind force and self-weight. 2 surface peeled off

[0005] At the same time, in order to solve the cumbersome problem of waterproof material preparation and coating process, the present invention uses nanomaterials and epoxy resin to directly cure, the preparation method is simple, and the coating method is convenient.
