| titleOfInvention | A kind of preparation method of poly aspartic acid High hydrophilous resin |
| abstract | The invention provides a kind of preparation method of poly aspartic acid High hydrophilous resin.The method adopts water as solvent, instead of the organic solvent N of current main flow synthesizing polyaspartic acid water-absorbing resin, dinethylformamide or dimethyl sulfoxide (DMSO), make linking agent with the silane coupling agent of amino-contained, and an one-step hydrolysis is crosslinked generates poly aspartic acid High hydrophilous resin.The saturated water absorbent rate of resin, up to 607 times, is better than the poly aspartic acid water-absorbing resin that prior art becomes to produce.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, compared with preparing poly aspartic acid High hydrophilous resin with organic phase, the present invention by cost savings to original less than 30%, and can not cause environmental pollution, be easy to suitability for industrialized production, have a extensive future. |
