Abstract

The invention discloses an antistatic and heat-resistant coating for a corrugated carton. The antistatic and heat-resistant coating comprises the following raw materials in parts by weight: 80-120 parts of modified phenolic resin, 60-90 parts of urea formaldehyde resin, 50-100 parts of acrylic resin, 20-40 parts of deionized water, 12-35 parts of graphite, 8-15 parts of carbon nanotubes, 2-9 parts of carbon fibers, 5-15 parts of bentonite, 3-9 parts of coal ash, 2-8 parts of calcium silicate, 6-12 parts of titanium dioxide, 3-9 parts of tin oxide, 3-12 parts of potassium chloride, 5-15 parts of cryolite, 1-5 parts of sodium fluoborate, 2-6 parts of anhydrous sodium sulfite, 3-8 parts of magnesium stearate, 2-9 parts of a silane coupling agent, 1-5 parts of a polyamide curing agent and 3-7 parts of dimethyl formamide. The invention also discloses a preparation method of the antistatic and heat-resistant coating for the corrugated carton. The coating prepared by using the preparation method can be used for effectively preventing static electricity from generating and also has high heat resistance.

Description

technical field [0001] The invention relates to the technical field of carton coatings, in particular to an antistatic heat-resistant coating for corrugated cartons and a preparation method thereof. Background technique [0002] Currently, corrugated boxes are rigid paper containers made of corrugated cardboard. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transportation packaging containers due to their superior performance and good processing performance, and have become the main force of transportation packaging. In addition to protecting the goods and facilitating storage and transportation, it also plays the role of beautifying and promoting the goods. Corrugated boxes are green and environmentally friendly products, which are conducive to environmental protection and are conducive to loading and unloading transportation. [0003] During the transportation of corrugated cartons in the prior art, there will be friction b...
