| titleOfInvention | Recovery method of alpha-cyanoacrylate dry glue |
| abstract | The invention relates to the technical field of recycling of alpha-cyanoacrylate, and particularly discloses a method for recycling alpha-cyanoacrylate dry glue, which comprises the following process steps: a. mixing the alpha-cyanoacrylate dry glue with a plasticizer and an organic solvent, and heating and dissolving to obtain a mixed solution; b. adding an alkaline solution into the mixed solution, washing to remove impurities, standing for layering, and removing a water phase; c. adding acid into the organic phase from which the water phase is removed to adjust the pH value to 2-3, and dehydrating and removing the organic solvent; d. adding polymerization inhibitor, and carrying out reduced pressure cracking to obtain the alpha-cyanoacrylate monomer. The invention discloses a method for recycling an a-cyanoacrylate polymer, which changes waste into valuable, and has the advantages of simple operation, easily obtained raw materials, easy large-scale production and obvious economic benefit. |
