Embodiment 1

[0022] A method for preparing a water-resistant corrugated packaging carton, comprising the steps of:

[0023] S1, the pulverization of coating, take 10 parts of thermosetting polymer, thermosetting polymer is one of allyl propylene polymer, phenolic resin and epoxy resin, then take 10 parts of petroleum wax and put it into a pulverizer to pulverize into powder, put the two items into the mixing device for thorough mixing;

[0024] S2. Preparation of paint. Put the powder mixed in S1 into a heating furnace to heat and stir. When the powder is in a molten state, stop heating and keep warm. The heating temperature is 66°C, which is higher than the melting point of petroleum wax and lower than that of thermosetting polymerization. solidification temperature, so that the thermosetting polymer is evenly and fully dispersed in the molten petroleum wax, and a small amount of antioxidant is added when melting;

[0025] S3, cardboard coating, take the surface layer of fiber paper and ...

Embodiment 2

[0031] A method for preparing a water-resistant corrugated packaging carton, comprising the steps of:

[0032] S1, the pulverization of coating, take 20 parts of thermosetting polymer, thermosetting polymer is one of allyl propylene polymer, phenolic resin and epoxy resin, then take 20 parts of petroleum wax and put it into a pulverizer to pulverize into powder, put the two items into the mixing device for thorough mixing;

[0033] S2. Preparation of paint. Put the powder mixed in S1 into a heating furnace to heat and stir. When the powder is in a molten state, stop heating and keep warm. The heating temperature is 67°C, which is higher than the melting point of petroleum wax and lower than that of thermosetting polymerization. solidification temperature, so that the thermosetting polymer is evenly and fully dispersed in the molten petroleum wax, and a small amount of antioxidant is added when melting;

[0034] S3, cardboard coating, take the surface layer of fiber paper and ...

Embodiment 3

[0040] A method for preparing a water-resistant corrugated packaging carton, comprising the steps of:

[0041] S1, pulverization of coating, take 30 parts of thermosetting polymer, thermosetting polymer is one of allyl propylene polymer, phenolic resin and epoxy resin, then take 30 parts of petroleum wax and put it into a pulverizer for pulverization into powder, put the two items into the mixing device for thorough mixing;

[0042] S2, preparation of paint, put the powder mixed in S1 into a heating furnace to heat and stir, stop heating and keep warm when the powder is in a molten state, the heating temperature is 68°C, which is higher than the melting point of petroleum wax and lower than that of thermosetting polymerization solidification temperature, so that the thermosetting polymer is evenly and fully dispersed in the molten petroleum wax, and a small amount of antioxidant is added when melting;

Abstract

The invention relates to the technical field of packaging materials, in particular to a preparation method of a waterproof corrugated packaging carton. The preparation method comprises the following steps: crushing coating, preparing the coating, smearing the coating onto a paperboard, hot pressing and curing, dip dyeing corrugated paper, preparing a corrugated paperboard, and preparing a carton.Compared with the existing corrugated paper packaging carton, the corrugated packaging carton prepared by adopting the preparation method of the invention has good water resistance, is prevented frombeing softened and damaged when being wetted by water, and is suitable for holding water-containing articles such as vegetables, fruits and the like.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a method for preparing a water-resistant corrugated packaging carton. Background technique [0002] Although existing corrugated cartons are widely used and can meet the packaging requirements of general commodities, some special commodities, such as the packaging of fresh-keeping products such as vegetables and fruits, require the box body of the packaging to be waterproof and moisture-proof. However, the existing corrugated boxes generally do not have water resistance and moisture resistance, and the box body is prone to softening and damage when exposed to water, resulting in leakage of articles. Contents of the invention [0003] The object of the present invention is to solve the disadvantage of poor water resistance of corrugated cartons in the prior art, and propose a method for preparing water-resistant corrugated packaging cartons. [0004] In order to ach...
