| titleOfInvention | A kind of three-layer co-extrusion diaphragm with high heat resistance and high strength and preparation method thereof |
| abstract | The invention relates to the field of multi-layer composite diaphragms for batteries, and discloses a three-layer co-extrusion diaphragm with high heat resistance and high strength and a preparation method thereof. In the diaphragm, the raw materials of the upper layer and the lower layer include: a polymer matrix, a macromonomer, and a high-temperature initiator; the raw materials of the middle layer include: polyethylene, a macromonomer, and a high-temperature initiator; the polymer matrix includes polyterephthalene One or more of ethylene formate, polybutylene terephthalate and polyethylene 2,6-naphthalate; the macromonomer includes polyethylene glycol methyl ether methyl one or more of poly(ethylene glycol) methacrylate, poly(ethylene glycol) methacrylate and poly(ethylene glycol) ether methacrylate. By adopting a specific matrix in the three layers and introducing a special macromonomer, the invention cooperates with the three-layer co-extrusion process, so that the temperature difference between the closing cell temperature and the film breaking temperature of the diaphragm can be increased, and the diaphragm can be better Good mechanical strength, heat resistance, liquid absorption and ionic conductivity. |
