| titleOfInvention | A kind of preparation method of high-strength and high-modulus highly-elastic urethane film |
| abstract | The present invention relates to a kind of preparation method of high-strength and high-modulus highly-elastic urethane film, belong to technology field of membrane materials.A kind of preparation method of high-strength and high-modulus highly-elastic urethane film of the present invention, the polyfluortetraethylene plate that scribbles polyurethane solutions will be scraped to be put into the coagulating bath for being mixed to get molecular weight anionic type surfactant by deionized water, ammonium salt, the organic solvent of amide bond, acetone and low phase, and mechanical agitation is used to coagulating bath, then after wet-formed and drying process, high-strength and high-modulus highly-elastic urethane film is obtained.The preparation method of the present invention strengthens while realizing the fracture strength, Young's modulus and elongation at break of polyurethane film, the polyurethane film fracture strength increase by 270 560% prepared by the present invention, elongation at break increase by 80 280%, Young's modulus increase by 50 270%.The preparation method process equipment of the present invention is simple, and cost is relatively low, pollution-free to ecological environment, and controllability is high, has great application prospect. |
