| titleOfInvention | Heat-resistant polyolefin microporous membrane and method for producing the same. |
| abstract | [PROBLEMS] To improve the safety of a lithium ion secondary battery, which is excellent in low shrinkage at high temperature, useful air permeability, compression resistance, electrolytic solution impregnation, mechanical properties, and surface roughness. Is a relatively large and highly productive heat-resistant polyolefin microporous membrane and a method for producing the same. SOLUTION: Ultrahigh molecular weight polyethylene 5-45 mass% and polyethylene 10-40 mass%, copolymer resin of 4-methyl-1-pentene and α-olefin having 3 or more carbon atoms, 10-50 mass%, polypropylene 5-30 mass%, ethylene-ethylene-butylene-ethylene block copolymer 0.1-3 mass%, block polymer 0.1-3 mass% of polypropylene and ethylene, propylene copolymer, polyolefin elastomer resin 0 A gel-like sheet obtained by melt-kneading a polyolefin mixture composed of 1-4% by mass and, if necessary, fine-particle inorganic filler with a plasticizer for film formation, extruding from a die, and cooling After stretching the molded product, the film-forming solvent is removed and heat-set. It has a shutdown temperature in the vicinity of 130 ° C, has a non-meltdown feature that does not break at high temperatures up to 160 ° C or higher, has low shrinkage at high temperatures, and has a relatively large surface roughness. The present invention provides a single-layer heat-resistant polyolefin microporous membrane excellent in a balance of properties such as compression resistance, electrolyte impregnation property, mechanical properties and the like, and a method for producing the same.
