Preparation method of paperboard antibacterial moistureproof agent

Abstract

The invention discloses a preparation method of a paperboard antibacterial moistureproof agent. The preparation method comprises dissolving turpentine in a dispersant to obtain a turpentine solution, mixing modified alkyd resin, microcrystalline wax, methylsilicone oil and Vaseline, heating the mixture at a temperature of 30-70 DEG C along with stirring to obtain a mixture, mixing the mixture, the turpentine solution and an emulsifier, stirring the mixture, heating the mixture to a temperature of 120-170 DEG C, adding 1N of a sodium hydroxide solution into the mixed solution, continuously heating the mixture for 10-30min, carrying out stirring emulsification, cooling the emulsion to the room temperature, dropwisely adding tea tree oil into the emulsion along with stirring and carrying out uniform stirring. The preparation method has simple processes and is free of special equipment. The paperboard antibacterial moistureproof agent has good moistureproof, anti-bacterium and anti-moth performances, is safe in use, does not pollute the environment and is suitable as a moistureproof agent in a carton package and especially as a carton moistureproof agent in a food package.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial and moisture-proof agent for cardboard, belonging to the technical field of carton packaging. Background technique [0002] Among all kinds of packaging for industrial products, corrugated boxes have become the mainstream of the packaging industry. Because of their light weight, foldability, low cost, environmental protection, easy specification changes, high-quality printing, and recycling, they can be used as renewable materials. Resources, therefore, are used more and more widely, but the surface of the carton is easily affected by moisture. After contact with water, various physical performance indicators will drop sharply. Especially when cartons are used to store and transport materials in humid tropics and subhumid tropics, the cartons are susceptible to moisture and are easily polluted by microorganisms such as mold, which in turn contaminate the items stored in the cartons.

[0002] Among all kinds of packaging for industrial products, corrugated boxes have become the mainstream of the packaging industry. Because of their light weight, foldability, low cost, environmental protection, easy specification changes, high-quality printing, and recycling, they can be used as renewable materials. Resources, therefore, are used more and more widely, but the surface of the carton is easy to be affected by moisture, and various physical performance indicators will drop sharply after being exposed to water.

Especially in the humid tropics and sub-humid tropics, when using cartons to store and transport materials, the cartons are prone to moisture and are easily polluted by microorganisms such as mold, which in turn contaminate the items stored in the cartons.
