Abstract

The invention discloses a mould-proof medical stone modified paperboard and a preparation method thereof. The method includes the steps that 1, Chinese herbal medicines are decocted in water to prepare a Chinese herbal medicine extracting solution; 2, medical stone, plant ash, sodium chloroplatinate and molybdenum disulfide are subjected to activation treatment to prepare an activation product in the presence of ultraviolet light; 3, the activation product and amino acid are mixed and then are subjected to modification treatment under the acidic conditions to prepare a modified activation product; 4, acrylic emulsion, polystyrene, dioctyl phthalate, aluminum oxide, boron nitride and sodium nitrite perform contact reaction, and then an emulsifier, the modified activation product and the Chinese herbal medicine extracting solution are mixed to prepare a mould-proof coating; 5, the mould-proof coating is coated on the surface of a paperboard body and is dried to prepare the mould-proof medical stone modified paperboard. The mould-proof medical stone modified paperboard has excellent mechanical, waterproof and antibacterial performance.

Description

technical field [0001] The present invention relates to cardboard, in particular, to a mildew-proof cardboard modified by medical stone and a preparation method thereof. Background technique [0002] Carton is the most common form of outer packaging for most products at present, and it is the first line of defense to protect product appearance, function, integrity, etc., and because water is the biggest culprit in causing damage to the appearance and function of many products, consumers are not interested in carton boxes. The water resistance has extremely high requirements. [0003] The method of enhancing the waterproofness of the carton 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 painting, spraying, etc. Existing carton waterproof coatings generally contain a large amount of macromolecules. After the carton is used for a long time, the coating layer on the surface of the car...
