Problems solved by technology

However, the corrugated cartons currently used for packaging are not very good in moisture resistance, which limits their application in humid environments
The current solution is to put a moisture-proof protective layer on the outside of the carton, but it increases the packaging cost. Another way is to coat a layer of moisture-proof agent on the outside of the carton. This method needs to solve the problem of moisture-proof agent and carton. Adhesive force and moisture-proof agent are easy to peel off. At present, neither of them has achieved the desired effect.

Embodiment 1

[0032] First, add 15 parts of polyethylene wax, 10 parts of xylene, 10 parts of phthalic anhydride, 5 parts of n-butanol, and 2 parts of sodium hydroxide into 60 parts of water, stir and mix evenly, and then heat the mixed material to 100 ℃, add 2 parts of rosin and 3 parts of paraffin, continue to stir for 3 hours, and finally cool down to room temperature and add 1 part of hydrochloric acid to adjust the overall pH value of the moisture-proof agent to 5 to obtain a moisture-proof agent for corrugated boxes.

Embodiment 2

[0034] First, add 10 parts of polyethylene wax, 5 parts of xylene, 5 parts of phthalic anhydride, 3 parts of n-butanol, and 1 part of sodium hydroxide into 70 parts of water, stir and mix evenly, and then heat the mixed material to 90 ℃, add 1 part of rosin and 5 parts of paraffin, continue to stir for 3 hours, and finally cool down to room temperature and add 3 parts of hydrochloric acid to adjust the overall pH value of the moisture-proof agent to 4 to obtain a moisture-proof agent for corrugated boxes.

Embodiment 3

[0036] First, 20 parts of polyethylene wax, 8 parts of xylene, 8 parts of phthalic anhydride, 5 parts of n-butanol, and 3 parts of sodium hydroxide are added to 50 parts of absolute ethanol and stirred evenly, and then the mixed material Heat to 95°C, add 3 parts of rosin and 4 parts of paraffin, continue stirring for 3 hours, and finally cool down to room temperature and add 2 parts of hydrochloric acid to adjust the overall pH value of the moisture-proof agent to 6 to obtain a moisture-proof agent for corrugated boxes.

Abstract

The present invention discloses a corrugated carton moisture-proofing agent. The corrugated carton moisture-proofing agent comprises the following components in parts by weight: 10-20 parts of polyethylene wax, 5-10 parts of xylene; 5-10 parts of phthalic anhydride; 3-5 parts of n-butanol; 3-5 parts of paraffin; 1-3 parts of rosin; 1-3 parts of sodium hydroxide; 1-3 parts of a pH regulator; and 50-70 parts of dispersion media. The present invention further discloses a preparation method of the corrugated carton moisture-proofing agent. According to the corrugated carton moisture-proofing agent and the preparation method therefor provided by the present invention, by optimizing the formula of the corrugated carton moisture-proofing agent, the corrugated carton moisture-proofing agent has high water-repellent ability, good water-proof effects and good adhesiveness on the carton, the service life of the carton is prolonged, and the preparation method is simple in technique and easy to operate, so that production capabilities are improved, and the application range of the moisture-proofing agent is expanded.

Description

technical field [0001] The invention relates to a moisture-proof agent and a preparation method thereof, in particular to a corrugated box moisture-proof agent and a preparation method thereof, and belongs to the technical field of papermaking additives. Background technique [0002] In the modern packaging industry, corrugated boxes are widely used due to their advantages of light weight, environmental protection, and low cost, and corrugated paper can also be recycled. However, the corrugated cartons currently used for packaging are not very good in moisture-proof effect, which limits their application in humid environments. The current solution is to put a moisture-proof protective layer on the outside of the carton, but it increases the packaging cost. Another way is to coat a layer of moisture-proof agent on the outside of the carton. This method needs to solve the problem of moisture-proof agent and carton. Adhesive force and moisture-proof agent are easy to peel off,...
