▎ 摘 要
NOVELTY - Modified urea melamine modified phenolic resin (UM-PF) paint comprises 0.2-0.7 pts. wt. graphene oxide, 25-40 pts. wt. water-soluble urea melamine modified phenolic resin, 1-4 pts. wt. defoamer, 2-8 pts. wt. dispersant, 1-7 pts. wt. auxiliary agent and 35-55 pts. wt. deionized water, where defoamer is organosilicone-based defoamer; auxiliary agent is phosphoric acid, ammonium sulfate and/or phosphate; and dispersant is ethanol, ketone and/or ethyl ketone. USE - Used as modified urea melamine modified phenolic resin paint. ADVANTAGE - The paint: has no-toxicity, harmless, excellent flame retardant effect, film forming effect and no peculiar smell; and improve the resin substrate strength and binding. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing modified UM-PF paint comprising (i) ultrasonically dispersing graphene oxide in deionized water to obtain graphene oxide solution, (ii) adding formaldehyde and phenol into the reaction kettle in a molar ratio of 1:1-2, (iii) adding sodium hydroxide and sulfuric acid during the reaction, (iv) adding urea and melamine and reacting to obtain UM-PF, (v) adding graphene oxide solution into UM-PF, stirring, heating, cooling to room temperature, and (vi) adding auxiliary agent, dispersant, defoamer into the reaction kettle and then stirring to obtain final product.
