Embodiment 1

[0017] Self-assembly of galvanized iron sheet, environmental protection, long-term and easy-to-clean anti-corrosion coating construction: take 29# galvanized iron sheet thickness 0.437mm, zinc layer thickness 0.02mm, use sandpaper to polish the aluminum alloy sample, remove impurities and oxide film, and then use acetone to clean it ultrasonically , Blow dry, soak the dried metal test piece in 3g / L polyacylamine hydrochloride solution for 15 minutes, put it in distilled water for 8 minutes after soaking, and then put it in polyacylamine hydrochloride solution with a concentration of 8g / L Sodium styrene sulfonate solution for 10 minutes, then take it out and put it in distilled water for 8 minutes, the above is a cycle; repeat this cycle many times to realize the alternate deposition of sodium polystyrene sulfonate-polypropyleneamine hydrochloride layer film; the metal test piece of the alternate deposition film of the sodium polystyrene sulfonate-polypropylene amine hydrochlori...

Embodiment 2

[0019] Self-assembly of galvanized aluminum iron sheet for self-assembly, environmental protection, long-term and easy-to-clean anti-corrosion coating construction: take a galvanized aluminum iron sheet with a thickness of 0.437mm and a zinc layer thickness of 0.1mm with an aluminum content of 35%, and use sandpaper to polish the aluminum alloy sample to remove impurities and Oxide film, then ultrasonically cleaned with acetone and dried, soaked the dried metal test piece in 2g / L polyallylamine hydrochloride solution for 5 minutes, placed in distilled water for 6 minutes after soaking, and then placed in Sodium polystyrene sulfonate solution with a concentration of 4g / L for 10 minutes, then take it out and place it in distilled water for 2 minutes, the above is a cycle; repeat this cycle many times to achieve sodium polystyrene sulfonate-polypropylene The alternate deposition film of amine hydrochloride layer; the metal test piece of the alternate deposition film of the sodium ...

Abstract

The invention discloses a method for constructing a self-assembly environment-friendly long-lasting easy-to-clean anticorrosion coating, and belongs to the technical field of chemical engineering. Theconstructing method is flexible, the technology is simple, the efficiency is high, the period is short, environmental protection and pollution free are achieved, the coating binding force is high, through the electrostatic self assembly, based on the electrostatic adsorption action of polyacrylamide hydrochloride and sodium polystyrene sulfonate electrolytes, urushiol is combined through the existence of polyelectrolytes, and gradual deposition is carried out to form a urushiol coating; and then the mode of layer-by-layer assembly is adopted to deposit the two polyelectrolytes to uniformly cover the surface of the urushiol coating, the absorption process is more uniform, film formation is more compact, the anticorrosion effect is the most lasting, efficient and table, and thus the anticorrosion effects such as galvanized sheet iron and aluminized zinc iron sheet are obviously improved.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, in particular to a method for constructing a self-assembled, environment-friendly, long-lasting and easy-to-clean anti-corrosion coating. Background technique [0002] Daily necessities made of tinplate are accepted by people for their durability. Watering cans, foreign oil tanks, buckets, downspouts, and downspouts made of tin are all relatively popular items. Every household buys things, and almost every household has iron pots, buckets, dustpans, funnels and other daily necessities made of tin. Once the traditional galvanized iron sheet has the phenomenon of "cold bridge condensation", the dew will corrode. After the iron sheet corrodes and rusts, the rust powder will pollute the room environment. The main quality problem of applying coatings on galvanized iron surfaces, such as roofing, drainage, ventilation, doors and windows, and other galvanized iron surfaces, is poor adhesion....
