Abstract

The invention discloses a moisture-proof agent for a carton and a preparation method of the moisture-proof agent. By virtue of the moisture-proof agent for the carton, the carton has good waterproof and moisture-proof effects; the adhesive force of the moisture-proof agent is further improved by adding rosin into components; the preparation method is simple and easy to implement, and the moisture-proof agent prepared by the preparation method is long-lasting in performance, good in ageing resistance, and good in economic benefit and social benefit.

Description

technical field [0001] The invention relates to a carton moisture-proof agent and a preparation method thereof, belonging to the technical field of carton packaging. Background technique [0002] Cartons are a type of packaging products that are widely used. They have the advantages of low cost and recyclability. However, the surface of cartons is easily affected by moisture, and the cartons will be damaged after contact with water. Therefore, it is necessary to develop a moisture-proof agent specially suitable for cartons to improve the moisture-proof performance of cartons and meet higher market requirements. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a carton moisture-proof agent with strong adhesion and good moisture-proof performance. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A carton moisture-pr...
