Abstract

The invention relates to a waterproof coating, in particular to a waterproof coating of a carton, which comprises the following components in weight part: 30-120 parts of paraffin micro-emulsion, 50-90 parts of simethicone, and 4-8 parts of emulsifier. The waterproof coating is prepared according to a method as follows: (1) heating the paraffin micro-emulsion to 50-180 degree C; (2) adding simethicone and stirring for 0.5-3 hours; and (3) adding the emulsifier, stirring at a high speed for 10-40 minutes, and cooling to the room temperature. The waterproof coating of the carton, disclosed by the invention, has no pollution on the human body and the environment, can be combined with the base material firmly, and has excellent waterproof property.

Description

technical field [0001] The invention relates to a water-based coating, in particular to a carton waterproof coating 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. 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. The existing carton waterproof coatings generally contain a large amount of organic solvents, which seriously pollute the air and do not meet the requirements of environmental protection; at the same time, the s...
