| titleOfInvention | A kind of polyaspartic acid water-absorbing resin and preparation method thereof |
| abstract | The preparation method of a kind of polyaspartic acid water-absorbing resin of the present invention.The method adopts epoxy types, as linking agent, poly aspartic acid and poly-aspartate derivant are carried out crosslinking reaction, the water-intake rate of obtained polyaspartic acid water-absorbing resin is high, after water suction, the intensity of water-absorbing resin is obviously better than the poly aspartic acid water-absorbing resin that prior art is produced, water-intake rate in physiological saline (0.9%NaCl solution) can reach more than 145 times, much larger than the poly aspartic acid water-absorbing resin that prior art is produced.The inventive method is simple to operate, and without the need for machine solvent in reaction process, the amount of solvent for use water is less, with low cost, and can not cause environmental pollution, is easy to suitability for industrialized production, has a extensive future. |
