Abstract

The invention discloses a bentonite-modified mould-proof cardboard and a preparation method thereof. The preparation method includes 1), decocting Chinese herbal medicines in water to obtain Chinese herbal medicine extract; 2), in the presence of ultraviolet rays, activating bentonite, plant ash, sodium chloroplatinate and molybdenum disulfide to obtain activators; 3), subjecting the activators and amino acids to modification under an acidic condition to obtain modified activators; 4), subjecting acrylic emulsion, polystyrene, dioctyl phthalate, aluminum oxide, boron nitride and sodium nitrite to contact reaction, and adding emulsifying agents, the modified activators and the Chinese herbal medicine extract into a reaction product with mixing to obtain a mould-proof coating; 5), applying the surfaces of a cardboard body with the mould-proof coating prior to drying so as to obtain the bentonite-modified mould-proof cardboard. The bentonite-modified mould-proof cardboard has the excellent mechanical, waterproof and antibacterial properties.

Description

technical field [0001] The invention relates to a cardboard, in particular to a bentonite-modified mildew-resistant cardboard and a preparation method thereof. Background technique [0002] Carton is currently the most common form of outer packaging for most products, and it is the first line of defense to protect product appearance, function, integrity, etc., and because water is the biggest culprit that causes damage to the appearance and function of many products, consumers are very concerned about cartons. Water resistance has extremely high requirements. [0003] The method of enhancing the waterproofness of cartons is mainly to add a waterproof coating layer on the surface of the carton, and the method of adding coating is mainly organic printing, manual brushing, spraying, etc. Existing waterproof coatings for cartons generally contain a large amount of macromolecules. After the cartons are used for a long time, the coating layer on the surface of the cartons will be...
