USE - Graphene polyurethane modified water-borne alkyd resin used in ocean anti-corrosive coating, wood coating, and antistatic coating. ADVANTAGE - The graphene polyurethane modified water-borne alkyd resin has good adhesive force, hardness, corrosion resistance, water resistance, and alkali resistance, and high gloss and antistatic performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene polyurethane modified water-borne alkyd resin, which involves: (A) adding dried graphene and dimethylol propionic acid into four-mouth reactor with thermometer, condensing pipe, and stirrer, heating at 75-80 degrees C, dropping polyisocyanate at constant velocity, uniformly at dropping time for 1 hour, and reacting for 2 hours to obtain activated intermediate; (B) adding vegetable oil fatty acid, phthalic anhydride, trimethylolpropane, dimethylbenzenee, isophthalic acid, benzoic acid, and neopentyl glycol in four-mouth reactor with thermometer, condensing pipe, water separator, and stirrer, heating at 140 degrees C, stirring for 1.5 hours, heating at 180 degrees C, preserving temperature for 2 hours, and determining acid value, raising temperature to 210 degrees C, measuring acid value every 20 minutes when acid value reaching theoretical design value, removing solvent, cooling at 80 degrees C, and adding activated intermediate at constant speed; and (C) adding catalyst dibutyl tin laurate, continuously reacting for 2 hours, testing reagent viscosity, and adding acetone to reducing viscosity, measuring NCO content when NCO content closing to theoretical design value, cooling at less than or equal to 45 degrees C at uniform velocity dropping neutralizing agent, and stirring for 0.5 hours, adding proper amount of de-ionized water, and filtering, removing acetone to obtain final product.
