| titleOfInvention | Deproteinised natural rubber and preparation method thereof |
| abstract | The invention discloses a deproteinised natural rubber preparation method including the following steps: 1) adding a stabilizer in a fresh natural rubber latex or a concentrated natural rubber latex for stabilizing; 2) adding deionized water to dilute the rubber latex, carrying out centrifugal separation to remove impurities, and collecting an upper rubber phase; 3) diluting the upper rubber phase obtained in the step 2) with deionized water, adding a compound enzyme preparation under stirring and weak alkali conditions, and degrading proteins in the rubber latex under certain reaction conditions; and 4) carrying out centrifugal separation with a centrifugal machine to remove impurities obtained after the proteins are degraded, carrying out repeated degradation to remove the proteins contained in the latex, and thus obtaining deproteinised natural rubber. In addition, the invention also discloses the deproteinised natural rubber prepared by the method. The content of protein amino acids of the deproteinised natural rubber can reach less than a 0.67 ppm reagent detection limit value, and the deproteinised natural rubber can be used in production of various medical latex products and can avoid generation of allergy caused by natural rubber. |
