Abstract
Nano SiO2 composite glass fiber barriers have large specific surface, good physical and chemical performances, and long service life in batteries. They are manufactured by uniformly spraying SiO2 dispersed liquid onto glass fiber barriers on the papermaking line before drying. The SiO2 dispersed liquid contains; disperser 0.1-2 wt.%, Nana SiO2 5-20 wt.%, and water 78-94.9%. The said Nano SiO2 composite glass fiber barriers can also be manufactured by mixing the SiO2 dispersed liquid with glass fiber pulp in normal routine of making process.
Description
Technical field
The present invention relates to baffle plate of lead acid storage battery.
Background technology
The VRLA battery is a kind of lean solution formula valve-control sealed lead acid battery, is state-of-the-art a kind of battery in the lead-acid battery, is widely used as post and telecommunications power supply, ups power, railway electrical source of power etc., and in electricity consumption places such as R﹠D institutions as emergency standby power.Because the requirement of cell sealing, the lean solution formula is adopted in the battery assembling, so require battery separator (barrier film) to have that the aperture is little, porosity is high, protect that fluidity is good, resistance is little, characteristic such as Cu, Fe ion concentration are low.
SiO
2It is the material that a kind of acidproof, chemical property is stable, hydrophily is strong.SiO
2Power applications begins from being used for open type lead-acid battery rubber separator the earliest in lead-acid battery separator, because the hydrophily of gum dividing plate is poor, resistance was big, so people mix a certain amount of SiO in rubber separator at that time
2Particle obviously improves the dividing plate performance, and battery is greatly improved.But, be limited to technical merit at that time, SiO
2Particle be bigger.
At the beginning of the nineties, people have invented the silica flour sealed lead acid storage battery, and it is with porosity height, SiO that specific surface is big
2Powder is placed directly between the positive and negative pole plate and (does not re-use dividing plate between the positive and negative pole plate) around the utmost point group, to keep the necessary sulfuric acid amount of battery charge and discharge, potentiality are provided for improving battery performance, and do not need to exert pressure and to pack utmost point group in the battery case into, simplified the battery packaging technology, this SiO
2Particle diameter is 5～40 μ m, and specific area is 20～40m
2/ g.
The dividing plate that adopts in the VRLA battery at present mainly is compound PE dividing plate and super glass wool dividing plate.Compound PE dividing plate is with the PE of super high molecular weight and ultra-fine SiO
2Powder and mineral oil or plasticizer mix, and are made wherein ultra-fine SiO through operations such as plasticizing, calenderings
2Effect be the water-retaining property that increases dividing plate, reduce the consumption of battery water in the charge and discharge process etc., this ultra-fine SiO
2Specific area is 100～190m
2/ g, particle diameter are tens μ m.
In recent years, nano material and nanometer technology are paid attention to because of its unique superiority is subjected to various countries' science and technology and industrial circle and government department, and research deepens continuously, and has obtained considerable progress.Preparation nanometer SiO
2Technology day by day ripe.
Nanometer SiO
2Particle diameter generally between 1～100nm, its specific area is up to 600m
2/ g has common SiO
2The unexistent peculiar property of particle.
Summary of the invention
Technical problem to be solved by this invention is to improve the specific area of baffle plate of lead acid storage battery, improves its water-retaining property, thereby improves the performance of VRLA battery, prolongs battery useful life.
Its special character of a kind of technical scheme that the present invention adopts is to be compounded with nanometer SiO on glass mat separator
2Particle.
The described nanometer SiO that on glass mat separator, is compounded with
2Particle is meant nanometer SiO
2Dispersion liquid evenly sprays before baking operation on the papermaking line and form described nanometer SiO on glass mat separator
2Dispersion liquid contains dispersant 0.1～2%, nanometer SiO in its weight
25～20%, water 78～94.9%.
Described dispersant is one or more the mixture in calgon, Sodium Polyacrylate, ethanol, the ptfe emulsion.
The described nanometer SiO that on glass mat separator, is compounded with
2Particle also can be meant nanometer SiO
2Dispersion liquid is uniformly coated on the glass mat separator on the papermaking line and forms, described nanometer SiO
2Dispersion liquid contains dispersant 0.1～2%, nanometer SiO in its weight
25～20%, water 78～94.9%.
Described dispersant is one or more the mixture in calgon, Sodium Polyacrylate, ethanol, the ptfe emulsion.
Its special character of another technical scheme that the present invention adopts is by mineral wool host material and nanometer SiO
2Particle mixes formation.
Described by mineral wool host material and nanometer SiO
2Particle mixes formation, is meant nanometer SiO
2Dispersion liquid joins in the mineral wool slurry, and the dividing plate papermaking process is made described nanometer SiO routinely
2The cotton dividing plate of compound glass.
Described dispersant is one or more the mixture in calgon, Sodium Polyacrylate, ethanol, the ptfe emulsion.
Glass mat separator of the present invention is meant the glass mat separator of the routine that present lead acid accumulator is used.
Because nanometer SiO
2Have very high specific area and surface energy, in water, very easily reunite, uniformly dispersed relatively poor, so the present invention need adopt suitable dispersion means, with dispersant---one or more the mixture in calgon, Sodium Polyacrylate, ethanol, the ptfe emulsion makes an addition to nanometer SiO
2In the material, add entry again and stir and make nanometer SiO
2Dispersion liquid.
With nanometer SiO
2Dispersion liquid is evenly spraying on the papermaking line or is being coated on the conventional glass mat separator, makes the cotton dividing plate of compound glass of the present invention; Perhaps with nanometer SiO
2Dispersion liquid is sneaked in the mineral wool dimension slurry, and glass mat separator papermaking process is routinely made the cotton dividing plate of compound glass of the present invention.
The testing performance index contrast of cotton dividing plate of compound glass of the present invention and conventional glass mat separator (pure glass mat separator) is as follows: nanometer SiO
