| titleOfInvention | A kind of preparation method of the calcium carbonate-filled polyurethane infiltrating and vaporizing membrane of dewatering nano |
| abstract | The present invention discloses a kind of preparation method of the calcium carbonate-filled polyurethane infiltrating and vaporizing membrane of dewatering nano, and its step is：(1) dried nano-calcium carbonate is added in deionized water, adds modifying agent, stirring reaction, after cleaned repeatedly with solvent hexane, remove unnecessary modifying agent, vacuum drying, grinding obtains dewatering nano calcium carbonate；(2) it is dissolved in after mixing end hydroxy butadiene, the diisocyanate of toluene 2,4 in xylene solvent, and adds catalyst dibutyltin dilaurylate, react after performed polymer, appropriate dewatering nano calcium carbonate is added, and diphenylmethanediamiand is added dropwise, reaction obtains casting solution；（3）Casting solution is carried out to be dried in vacuo after drying naturally under casting film-forming, normal temperature on polyfluortetraethylene plate after standing and defoaming, infiltrating and vaporizing membrane is obtained.The inventive method production stage is simple, and easy to operate, production cost is low, and film has good separating effect to the butanol/water of low concentration, and prospects for commercial application is wide. |
