| titleOfInvention | A kind of high temperature resistance multilayer micro-pore septum and preparation method thereof |
| abstract | The invention discloses a kind of high temperature resistance multilayer micro-pore septums and preparation method thereof.The high temperature resistance multilayer micro-pore septum, including at least one layer of poly- naphthalene ester layer, the poly- naphthalene ester layer is made of following components in percentage by weight: polyethylene naphthalate 55.5~79.8%, ultra-high molecular weight polyethylene 20~40%, nucleating agent 0.1~40%, antioxidant 0.1~0.5%；The average molecular weight of the polyethylene naphthalate is 2 × 10 4 ~3.5 × 10 4 , fusing point is 250~270 DEG C, and glass transition temperature is 110~130 DEG C, and inherent viscosity is 0.8~1.2dL/g；The average molecular weight of the ultra-high molecular weight polyethylene is 1.5 × 10 6 ~2.5 × 10 6 .The high temperature resistance multilayer micro-pore septum the preparation method comprises the following steps: prepare poly- naphthalene ester melt and polypropylene melt respectively, the slab after multi-layer co-extruded die head extrusion, gained sheet preheated after again through biaxial tension, thermal finalization processing to get.There are high molten broken temperature and low closed pore temperature, and good mechanical properties using multi-layer microporous diaphragm made from formula of the present invention and method. |
