| titleOfInvention | A kind of low temperature resistant, high strength and high toughness modified fluororubber semi-interpenetrating network film material and preparation method thereof |
| abstract | The invention discloses a modified fluororubber semi-interpenetrating network film material and a preparation method thereof. The modified fluororubber semi-interpenetrating network film material comprises the following steps: preparing a first component solution: adding solid fluororubber to a In the solvent, stir at 60°C for 2 hours and then cool at room temperature; the second component solution preparation: add polyisocyanate curing agent to the hydroxyl-terminated liquid fluororubber, stir evenly, then add the catalyst, and stir at room temperature for 10 minutes; the third component solution Preparation: Dissolve glycol, fluorine-containing isocyanate and fluorine-containing small molecule chain extender in solvent, stir evenly, then add catalyst and stir at room temperature for 10min; film material preparation: mix the first component solution, the second component The divided solution and the third component solution are added to the container, stirred and mixed at room temperature for 20 minutes, and placed for 10 minutes to remove foam to obtain a blended solution. Compared with the traditional fluororubber material, the low temperature performance and the physical and mechanical properties of the modified fluororubber semi-interpenetrating network film material prepared by the invention are significantly improved. |
