Abstract
An electrically conductive paint for the inner surface of battery shell is prepared from one or more of polyurethane resin, acrylic resin and epoxy resin (10-20 wt portions), electric conducting powder (30-50) and organic solvent (30-60) through mixing said resin with disperser, and sequentially adding organic solvent, electric conducting powder and assistant. Its advantages are use of spray coating, high stability and no pollution.
Description
Technical field
The present invention relates to the paint field field, in more detail electrically conductive paint for internal surface of battery shell.
The invention still further relates to the preparation method of this coating.
Background technology
China's alkaline cell adopts electroplate liquid to carry out electronickelling technology plating to battery case in producing more, and is seriously polluted, and the bore of battery case is little simultaneously, and body is long, can form deep hole, blind hole.Galvanized distribution of current relationship makes inner walls of deep holes be difficult to cover coating fully, equably, and interior wall coating often [approach partially, make the percentage of A-class goods lower, battery electrical property in preservation period descends naturally, and the SC short circuit current is 4-6.
Summary of the invention
The object of the present invention is to provide a kind of electrically conductive paint for internal surface of battery shell, this coating does not need to apply with electro-plating method, and uses the Airless spraying method, and internal surface of battery shell is covered fully, and coating thickness is even, steady quality, and percentage of A-class goods height, pollution-free.
The present invention also aims to provide the preparation method of above-mentioned coating.
The parts by weight of electrically conductive paint for internal surface of battery shell of the present invention are composed as follows:
Resin 10-20

Described resin be polyurethane resin, acrylic resin, Resins, epoxy one or more.
Described conducting powder is metal powder and/or the carbon dust with electroconductibility, and described metal powder comprises: copper powder, silver powder, nickel powder wherein one or more; Described carbon dust is acetylene carbon black and/or Graphite Powder 99.
Described organic solvent is the solvent of resin, comprises acetone, butanone, chloroform, gasoline or benzene.Wherein butanone is optimal selection.
In order to obtain steady quality, uniform coating, can in coating, add dispersion agent 0.1-1 part weight.
Described dispersion agent is polyurethane resin to be scattered in the solvent and the tensio-active agent that forms colloidal solution.Nonionogenic tenside ethoxylation methyl glucoside stearate for example, the methyl glucoside stearate, lauroyl diethanolamine, propylene glycol monostearate, Arlacel-20, Arlacel-40, Arlacel-60, Arlacel-80, tween 20, Tween-40, Tween-60, tween-80, glyceryl monostearate, fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene, polyoxyethylene stearic acid ester, sucrose fatty ester, polyethylene oxide-poly(propylene oxide), Brij92, polyoxyethylene (n) cocounut oil acyl thanomin, the polyoxypropylene butyl ether, Protanal Ester SD-LB, BYK163 wherein one or more.The contriver is through dispersant effect the best of exploration discovery commodity BYK163 by name.
In order further to improve the conductivity of coating, can add conductive auxiliary agent 0.5-2 part weight in the coating.The contriver is through the conductive auxiliary agent best results of exploration discovery commodity EFKA781 by name.
The preparation method of coating of the present invention mixes said components, can use.
The blended preferred order is first with polyurethane resin and dispersant, adds organic solvent and conducting powder, adds conductive auxiliary agent at last.
Preparation method's top condition of coating of the present invention is to stir polyurethane resin and mixture of dispersing agents 15-35 minute; Add organic solvent and conducting powder, stirred 5-20 minute, be ground to particle diameter less than 10 microns; Add conductive auxiliary agent, stirred 2-10 minute.
The present invention's advantage compared with prior art is:
(1) Fa Ming electrically conductive paint for internal surface of battery shell makes the production technique of battery change almost free of contamination Airless spraying into by polluting bigger water plating, reaches environmental requirement.
(2) Fa Ming electrically conductive paint for internal surface of battery shell makes the production technique of battery can adopt the Airless spraying method, and coat-thickness is even, steady quality, and the percentage of A-class goods reaches 100%, and SC circuit reaches 14-16.
