| titleOfInvention | A kind of self-healing water-based polyurethane anti-corrosion coating and preparation method thereof |
| abstract | The invention provides a self-healing water-based polyurethane anti-corrosion coating and a preparation method thereof. The coating is prepared by the following components in parts by weight: graphene oxide (GO) 0.002-0.005 parts, water-based polyurethane emulsion (WPU) 20-50 parts, tung oil 5-20 parts, polyvinyl alcohol (PVA) 5-15 parts, silane coupling agent 1-10 parts, phosphoric acid 1-10 parts, photoinitiator 0.01-0.4 parts and deionized 30-110 parts of water; the solid content of the coating is 20-40%. The coating preparation method is as follows: GO, PVA, tung oil, deionized water, WPU, silane coupling agent and photoinitiator are sequentially added into a reactor, stirred evenly, and left at room temperature for 0.5-2h. The coating made of the self-healing water-based polyurethane anti-corrosion coating provided by the invention has a smooth and uniform surface, bright color, stable structure, good thermal stability, strong water resistance, excellent mechanical properties, excellent adhesion, corrosion resistance, Abrasion resistance and self-healing. |
