| description | The invention relates to the field of high polymer materials, in particular to organosilicone modified polyurethane resin and a preparation method thereof. According to the preparation method, raw materials comprise polyether polyol, isoferal diisocyanate, a catalyst and carbon terminated hydroxyl polydimethylsiloxane. The preparation method comprises the steps that polyether polyol, isoferal diisocyanate, the catalyst and carbon terminated hydroxyl polydimethylsiloxane are placed in a reaction still, after complete reacting under the heating condition, the product is cooled to room temperature, and a pre-polymerized material is obtained; the obtained pre-polymerized material and 1,4-butanediol react under the heating condition, and ethyl alcohol is added for terminating; the organosilicone modified polyurethane resin is obtained after cooling is carried out. The organosilicone modified polyurethane resin has the advantages of being low in surface energy, excellent in heat resistance and mechanical performanc |
