Abstract

The invention discloses a kaolin modified mouldproof paper board and a preparation method thereof. The preparation method comprises the following steps: 1) putting Chinese herbal medicines into water to be decocted, so as to obtain a Chinese herbal medicine extracting solution; 2) in presence of ultraviolet ray, carrying out activating treatment on kaolin, plant ash, sodium chloroplatinate and molybdenum disulfide, so as to obtain an activator; 3) under acidic condition, mixing the activator with amino acid, and then modifying, so as to obtain a modified activator; 4) carrying out contact reaction on acrylic emulsion, polystyrene, dioctyl phthalate, aluminium oxide, boron nitride and sodium nitrite, then adding an emulsifying agent, the modified activator and the Chinese herbal medicine extracting solution, and mixing, so as to obtain mouldproof paint; and 5) coating the mouldproof paint on the surface of a paper board body, and drying, so that the kaolin modified mouldproof paper board is obtained. The mouldproof paper board has excellent mechanical, waterproof and antibacterial properties.

Description

technical field [0001] The invention relates to a cardboard, in particular to a kaolin-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 becom...
