▎ 摘  要

NOVELTY - Improving brittleness of melamine-impregnated paper comprises (i) glue impregnating, (ii) emulsion coating is: (iia) mixing 1-2 pts. wt. polyvinyl acetate, 2-4 pts. wt. polyvinylidene fluoride, 1-2 pts. wt. graphene oxide, 1-2 pts. wt. nano silicon dioxide and 90-94 pts. wt. absolute ethanol, ultrasonically vibrating, then adding 5-8 pts. wt. N-β-(aminoethyl)-γ-aminopropyltrimethoxysilane, and stirring to obtain stable emulsion, and (iib) applying the emulsion on both sides of the obtained melamine impregnated paper, and drying, and (iii) glue coating. USE - The method is useful for improving brittleness of melamine-impregnated paper (claimed). ADVANTAGE - The method: improves the impact resistance of the melamine impregnated paper.
