| titleOfInvention | Preparation method of chitin modified water polyurethane elastic body |
| abstract | The present invention discloses a method for preparing a chitosan modified aqueous polyurethane elastomer, which comprises the following steps that polyisocyanate firstly reacts with poly-polyatomic alcohol, glycol or diamine, and then a polyurethane prepolymer is obtained; the polyurethane prepolymer is dissolved by organic solvent, an ionized agent is added in, and then an ionized polyurethane prepolymer is obtained; the ionized polyurethane prepolymer reacts with a chitosan water solution and emulsifier, polyurethane emulsion or microemulsion is obtained, a film can be also formed. The present invention has the advantage of simple preparation method, the prepared chitosan modified embedded-section polyurethane elastomer has the good performance of good mechanical performance, easy processing, fine oil and water resistance, controllable performance, good biocompatibility, biodegradability, high bioactivity, fine blood contact performance, etc. The present invention can be applied to the field of mechanical industry, construction industry, sports, medical treatment, etc. and has a wide purpose on the aspects of life science study, medical materials and medical apparatus. |
