| titleOfInvention | High-liquid-absorption diatomite-PVA (polyvinyl alcohol) coated membrane and preparation method thereof |
| abstract | The invention provides a high liquid absorption diatomite-PVA coating diaphragm, which is obtained by mixing the following raw materials in parts by mass, coating the mixture on a base film and drying the base film: 50-60 parts by mass of diatomite; 6.1 parts by mass of PVA; 8.5 parts by mass of an anti-settling agent; 1 part by mass of a wetting agent; 24.4 to 44.4 parts by mass of pure water. The diatomite-PVA coated diaphragm provided by the invention can improve the porosity of the diaphragm from 40% to 61%, and provides more positions for the diaphragm to adsorb electrolyte. And the liquid absorption of the diaphragm is obviously improved by about 23.4 percent compared with that of the base film. PVA polyvinyl alcohol is a long-chain polymer, small particles in a slurry system have a strong winding and coating effect, the particle size of the slurry can be controlled, and dispersed small particles are wound and coated into uniform large particles with uniform and stable particle size. Compared with a base film, the diatomite-PVA coated diaphragm provided by the invention has the advantages that the thermal stability, the contact angle, the volume resistance and the ionic conductivity are obviously improved. |
