Abstract
The invention belongs to capacitor technology fields, and in particular to a kind of processing method for improving capacitor surface corrosion resistance includes herein below：Layer of surface treatment fluid is applied in vitro in capacitor protector, is then sequentially entered three section baking ovens and is dried；Wherein, surface treatment liquid is the modification ternary carboxyl vinyl chloride-vinyl acetate resin that solid content is 15%；Stainless steel capacitor casing surface after the drying is coated with one layer of antirusting paint.Preliminary treatment is carried out to stainless steel capacitor casing surface using surface treatment liquid in the present invention, can make its on stainless steel metal ground hinge, enable what there is antirust function coating effectively to stablize to be attached to capacitor casing surface, stainless steel capacitor casing surface tension after processing reduces, and can improve the adhesive strength of antirust function coating；Antirust function coating material crosslink density rises, and nano effect enhancing, thermal stability, impact flexibility improve, while there is stronger corrosion resistance and resistance to mechanical to scratch performance, and service life extends.
Description
Technical field
The invention belongs to capacitor technology fields, and in particular to a kind of processing side for improving capacitor surface corrosion resistance
Method.
Background technology
As electronic product is to slim, miniaturization, electronic circuit develops to multi-layer board, electronic component also rapidly to
Miniaturization, surface mount manner are fast-developing, therefore sheet component includes sheet type aluminum electrolytic paper roll around as cylinder-like structure
And be bonded as one using adhesive tape, it is packaged after being impregnated with high temperature resistant electrolyte using rubber plug and shell, and such aluminium electroloysis is electric
It is internal since high temperature action can cause the adhesive tape of winding core bag to melt fracture when container is by higher reflow soldering furnace temperature
There is situations such as loose, adhesive tape comes off in core bag, and electrical property is caused to deteriorate, and production reliability reduces, traditional capacitor, band adhesive tape
Mainly it is made using homogenous materials such as polypropylene or polyphenylene sulfides, if fruit product is when by high-temp leadless Reflow Soldering,
It is loose that core bag can occur, production reliability reduces, situations such as adhesive tape comes off, although its theoretical resistance to temperature value is higher, practical application
In be present with softening stretching resistance decline situation in addition be present with the bad phenomenons such as aging cracking, cause product reliability can not
Meet design requirement, with the continuous extension of the application field of electrolytic capacitor, capacitor is widely used in the blocking in electric furnace
Logical, coupling, bypass, filtering, resonant tank, energy conversion, control etc., in order to extend the service life of capacitor, to portion
The surface of point capacitor is handled, due to some existing stainless steel case bulk capacitors, mainly to capacitor casing surface into
Then row shotblasting carries out spray painting protection, which needs using shot-blasting machine, workshop dust, noise pollution compared with
To be serious, industry is also more complicated, has certain restriction to product quality and production efficiency, and its corrosion resistance is not changed effectively
It is kind.
The content of the invention
The purpose of the present invention is being directed to the problem of existing, a kind of processing side for improving capacitor surface corrosion resistance is provided
Method.
The present invention is achieved by the following technical solutions：A kind of processing method for improving capacitor surface corrosion resistance,
Including herein below：
（1）Layer of surface treatment fluid is applied in vitro in capacitor protector, is then sequentially entered three section baking ovens and is dried, three sections
The temperature of baking oven is followed successively by 38 DEG C, 52 DEG C, 80 DEG C；
Wherein, surface treatment liquid is the modification ternary carboxyl vinyl chloride-vinyl acetate resin that solid content is 15%；
（2）Stainless steel capacitor casing surface after the drying is coated with one layer of antirusting paint；
Wherein, antirusting paint includes the raw material of following parts by weight：Water soluble phenol resin 38-42, isopropanol core-shell emulsion
12-16, butyl acrylate 8-12, somsanit 2-4, Nano-lanthanum hydroxide 1-3, p-methyl benzenesulfonic acid 3-6, to toluene sulphur
Acyl azide 2-4 is sintered ash 5-8, palm oil 2-6, sebacic dihydrazide 3-7, bismuth and ammonium citrate 0.2-0.6,3- amino -1,2,4-
Triazole 1.6-1.8, dimethyl sulfoxide (DMSO) 3-6, passive oxidation calcium 2-5, basalt fibre 8-15, mass fraction is 6% citric acid
Aqueous solution 7-10.
As further improvement of these options, it is described three section oven for drying times be followed successively by 0.5-1 it is small when, 1.5-
2 it is small when, 30-40 minutes.
As further improvement of these options, the method for modifying of the modified ternary carboxyl vinyl chloride-vinyl acetate resin is：With 12%
Chromic acid impregnate ternary carboxyl vinyl chloride-vinyl acetate resin 15-20 minutes, then take out and use deionized water rinsing；Ternary carboxylic after treatment again
It is added in base vinyl chloride-vinyl acetate resin and is equivalent to the strontium carbonate of its weight 2%, 1.8% nano silicon oxide and 3% diisopropyl hydramine,
It is dispersed with stirring 10-15 minutes with 3200-3500 revs/min of speed under conditions of 180-200 DEG C, resulting material is diluted with water
Be 15% to solid content, be further continued for scattered stirring 5 minutes to obtain the final product.
As further improvement of these options, the preparation method of the antirusting paint comprises the following steps：
（1）By water soluble phenol resin, isopropanol core-shell emulsion, somsanit, Nano-lanthanum hydroxide, sintering ash,
After 3- amino -1,2,4- triazoles and basalt fibre mix according to the above ratio, in supersonic frequency 22KHz, the item of power 100W
