Description
Technical field
The present invention relates to accumulator field, especially relate to a kind of battery separator.
Background technology
Lead-acid accumulator is widely used, and worldwide output value yield all occupies all kinds of electrochmical power source first place, and the battery that represents therein is analysing valve control type lead-acid accumulator battery.This lead-acid accumulator relies on two kinds of different mode fixed electrolytes, one is AGM technology, i.e. by AGM dividing plate fixed electrolyte, most domestic lead-acid accumulator is all by this kind of technology now, but it has, and clapboard aperture performance the biggest, pressure is bad, be easily caused the shortcomings such as acid layering.
Meanwhile, generally there is the shortcoming that heat stability is low, fire resistance is low, toughness is bad in existing battery separator.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and a kind of battery separator is provided, heat stability is high, fire resistance is high and good toughness, and service life is long.
The purpose of the present invention can be achieved through the following technical solutions: a kind of battery separator, including the component of following weight portion:
Preferably, described Merlon is phosgenation aromatic copolycarbonate, and the weight average molecular weight of described Merlon is 20000～35000.
Preferably, the silicone content of described siliceous Merlon is 6～10%, and the weight average molecular weight of described siliceous Merlon is 25000～40000.
Preferably, the molecular weight of described acrylonitritrile-styrene resin is 130000～150000, and described acrylonitritrile-styrene resin includes 22～the acrylonitrile of 29% and 71～the styrene of 78%.
Preferably, described toughener is the one in methyl methacrylate silastic copolymer, acrylic compounds toughener, acrylic acid-silicone rubber kinds toughener, ethylene-methyl acrylate, Ethylene-butyl acrylate.
Preferably, described antioxidant is the one in antioxidant 1076, irgasfos 168.
Preferably, described lubricant is ethylene bis stearamide.
The method have the advantages that
The present invention is by using a certain proportion of Merlon, siliceous polycarbonate resin, the mixing of acrylonitritrile-styrene resin, by suitable toughener, inducing shear band produces, substrate and dispersion phase is made jointly to absorb energy, improve toughness, and make material can well keep toughness after long term thermal is deposited；By fire retarding synergist, with the addition of of nitrogenated flame retardant, improve the fire resistance of material；Existence due to inorganic nano-particle so that while material has relatively low mold shrinkage, maintains higher toughness；The use of the acrylic acid series additive of perfluoroalkyl, can being completely migrating to surface during product injection mo(u)lding, to form a kind of protecting film, this layer of protecting film and water incompatible and have the performance of stronger acid and alkali-resistance, improves the service life of dividing plate.
Detailed description of the invention
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, it is described in detail below in conjunction with specific embodiment.
