| titleOfInvention | Preparation method of high-surface-area macroporous melamine resin |
| abstract | The invention relates to a preparation method of a high-surface-area macroporous melamine resin, belonging to the technical field of preparation of new chemical materials. Firstly, the metered melamine and formaldehyde are dissolved in waterAdding the solution and the mixed solvent into a three-neck flask, and stirring and reacting for 1h at 80 ℃ by taking NaOH as a catalyst; then naturally cooling to room temperature, adding concentrated hydrochloric acid to adjust the pH value of the mixture to 2-6 to obtain an acidic prepolymer, curing the acidic prepolymer in a hydrothermal kettle, washing the cured block with ethanol to obtain the high-surface-area macroporous melamine resin, wherein the specific surface area of the high-surface-area macroporous melamine resin can reach 1000m 2 A pore size of about 8 to 30nm per gram. The macroporous melamine resin with high surface area prepared by the invention can be used in the fields of catalyst preparation, selective adsorption of acid gas and the like. |
