[0003] However, most of the commercially available chemical barrels have the defects of anti-aging and poor heat insulation performance. This application prepares functionalized modified nano-hydroxyapatite, nitrogen-doped carbon / silica-graphene composite, and mixes it with mixed into the nano-composite coating, and then evenly sprayed on the surface of the chemical barrel, and dried naturally to obtain an anti-aging, heat-insulating, and leak-proof chemical barrel

Abstract
The invention discloses a method for preparing an anti-aging leakage-proof chemical barrel. The method comprises the following steps: dissolving nano stearic acid with absolute ethyl alcohol, then adding a formed solution into nano hydroxyapatite slurry, carrying out a reaction under heating and stirring, performing centrifugal washing with absolute ethyl alcohol, and performing drying and grinding to obtain functionalization modified nano hydroxyapatite; putting a nitrogen source, a carbon source, silicon dioxide nanoparticles, and graphene oxide subjected to surface silylanization modification treatment into a ball milling tank, adding absolute ethyl alcohol and performing ball milling, then performing drying overnight, putting milled materials into a vacuum tube furnace, performing heattreatment in an argon atmosphere, and performing cooling to room temperature to obtain a nitrogen-doped carbon/silicon dioxide-graphene complex; and performing mixed soaking on polyvinyl butyral andabsolute ethyl alcohol for full swelling, performing uniform stirring, then performing ultrasonic treatment for bubble removal, then performing uniform mixing with a lanthanum hexaboride dispersion liquid, the functionalization modified nano hydroxyapatite and the nitrogen-doped carbon/silicon dioxide-graphene complex to obtain a nano composite coating, uniformly spraying the nano composite coating onto the surface of a chemical barrel, and performing natural drying to obtain the anti-aging leakage-proof chemical barrel.
Description
technical field [0001] The invention belongs to the field of chemical barrels, and in particular relates to a method for preparing anti-aging and leak-proof chemical barrels. Background technique [0002] Chemical barrels are tools used in chemicals, dyes, medicines, and pesticides. They have the characteristics of various colors and beautiful appearance. Most of the chemical barrels are made of plastic, generally called plastic chemical barrels and plastic chemical barrels. They are developed and blow-molded using scientific formulas. They have various colors and beautiful appearance. Deformation and other aspects meet the packaging index, which is an ideal choice for long-distance transportation of chemical product packaging materials. Plastic chemical barrels have the advantages of integral polyethylene one-time forming without seams, light weight, acid and alkali resistance, long life, and compliance with hygienic standards. It can replace stainless steel, titanium and...
