Embodiment Construction

[0009] The present invention will be further described below in conjunction with embodiment

[0010] 1. Accurately weigh 15% low molecular weight polyethylene; 40% paraffin; 20% beeswax; 5% palm wax; 2% emulsifier A; 2% emulsifier B; 13% emulsifier C; deionized water, the balance ,spare.

[0011] 2. Preparation method

[0012] In a reaction kettle equipped with a stirrer, a thermometer and a hopper, add measured deionized water, low molecular polyethylene, paraffin wax, beeswax, and palm wax to heat and stir. When the temperature rises to 90°C, start adding them dropwise Emulsifier A, emulsifier B, and emulsifier C are added dropwise within 1 hour at constant temperature. After the reaction is complete, start to lower the temperature and continue to stir for 30 minutes, measure the viscosity value, and when it reaches 45Pa.S~50Pa.S, the product is obtained.

Abstract

The invention relates to a moistureproof glazing agent for corrugated paper cartons and a preparation method thereof. The moistureproof glazing agent for corrugated paper cartons is mainly composed of low molecular polyethylene, paraffin, beeswax, palm wax, emulsifier A, emulsifier B, emulsifier C and deionized water. The moistureproof glazing agent for corrugated paper cartons has advantages of hard film, strong adhesion force and good wear resistance; and has characteristics of water repellency, water resistance, moisture proof, and shining surface.

Description

technical field [0001] The invention relates to a moisture-proof glazing agent for corrugated cartons and a preparation method thereof, which belongs to the technical field of packaging aids for paper products. Background technique [0002] Corrugated cartons play a very important role in the protection of commodity packaging during transportation and storage. The corrugated cartons are treated with moisture-proof glazing to achieve the properties of rain-shielding, hydrophobic, water-resistant and moisture-proof, and to delay the cartons from absorbing moisture. Speed, to ensure that the compressive strength of the carton can be played normally, and the ultimate purpose of protecting the product has very important practical significance. Secondly, it can improve the surface gloss of the carton and make the color more vivid. [0003] At present, there are two main categories of products used for moisture-proof glazing of corrugated cartons: one is glazing oil, cooked tung oi...
