| titleOfInvention | Polyurethane/Houttuynia cordata blend microporous membrane |
| abstract | The invention relates to a polyurethane/Houttuynia cordata blended microporous membrane, which is obtained by mixing the following components in a solution: 10-25 parts of polyurethane/Houttuynia cordata, wherein the mass fraction of Houttuynia cordata is 0.2-0.8; N , 75-90 copies of N-dimethylformamide. Add polyurethane, N,N-dimethylformamide and powdered Houttuynia cordata into a clean and dry three-necked bottle, and continue stirring in a 60°C water bath until completely dissolved to obtain a casting liquid; after vacuum defoaming, dry and clean The glass plate is scraped to make a casting solution with uniform thickness and immediately immersed in deionized water; after the casting solution is separated into a film, the obtained membrane is washed with clean water to remove the solvent on the surface of the membrane, and the membrane is immersed in glycerol solution. After a period of time, take it out to dry naturally. The blended microporous membrane has excellent combined properties, namely better film-forming properties, water flux and high air permeability. The preparation technology and production process of the present invention are relatively simple, and are easy to be produced and realized. |
