Description
Technical field
The present invention relates to a kind of oil tank of transformer spraying technologies.
Background technology
Fuel tank is the shell of transformer, built-in iron core and winding and is full of transformer oil, and iron core and winding is made to be immersed in oil.
Transformer oil plays insulation and cooling effect.For high-power transformer generally there are two fuel tank, one is ontology fuel tank；One is to have load to wither
Pressure oil case, on-load voltage regulation fuel tank is interior to be equipped with tap switch.This is because tap switch will produce electric arc in operation, if into
Row frequent operation will make the decreasing insulating of oil, therefore it is individually placed by tap switch to set an individual fuel tank.
Common oil tank of transformer presses the size of its capacity, there is 3 kinds of box fuel tank, bell type tank and sealed fuel tank bases
This pattern.
CN102962187A discloses the enamelling process of a kind of oil tank of transformer and its parts, includes the following steps：The
One step, the allotment first painted；Second step, after paint deployment is good, with the sand net filtration of 120~180 mesh；Third walks, and carries out
Japanning；4th step, is painted with after paint, is dried.
CN106064139A discloses a kind of external coating technique of oil tank of transformer, includes the following steps：1）To oil
Case, combination become fuel tank, combination becomes door-plate and surface and oil contaminant compared with the pre- ungrease treatment of the advanced row of multi-work piece；2）Degreasing and rust removal：Surface oil
Dirt directly enters slot compared with light industry part and carries out room temperature processing；3）First of washing：Normal-temperature operation, workpiece control under liquid, are front and back, upper and lower
It swings；4）Second is washed：Normal-temperature operation, workpiece control under liquid, are front and back, swinging up and down；5）Phosphatization；6）Hot water embathes：Slot
Liquid temperature is not less than 70 DEG C, 1~2 min of time；7）Drying；8）Coating prime lacquer：In the inner and outer wall spray-applied primer of babinet；9）
Application intermediate layer paint：Intermediate layer paint is sprayed in the inner and outer wall of babinet；10）Coating finish：In the inner and outer wall spray-coating surface of babinet
Paint.
Existing oil tank of transformer sprays paint film, primary disadvantage is that easy to produce fall off, slight crack, to make tank body of oil tank
There is the phenomenon that corrosion, while the measure without preventing issuable collision in routine use.
Invention content
The purpose of the present invention is：There is provided a kind of oil tank of transformer spraying technology, it is characterised in that following steps：
Step 1. cleans the fuel tank that sprays of needs, phosphatization, drying process.
Step 2. sprays first of paint film in the inner side and outer side of fuel tank.
Step 3. after drying, sprays one layer of elastic resin buffer layer on first of paint film of fuel tank.
Second paint film is sprayed on elastic resin buffer layer after step 4. drying.
First of paint film is using chlorinated rubber cloud iron paint.
The elastic resin buffer layer preparation method is：By weight, by pyromellitic acid anhydride, diphenyldiamine
It is dissolved in dimethylformamide, bis- (trimethylsiloxy group) cyclobutanes of 1,2- is added, 1,1- crown ether -4 dimethyl sila -11- rise
Temperature reacts 3-8h, is added Glutathione Sepharose into product after reaction to 125-140 DEG C, calcium carbonate to get to
Elastic resin buffer layer.
The second paint film is using epoxy coating.
The diphenyldiamine, quality dosage are the 60-75% of pyromellitic acid anhydride.
Bis- (trimethylsiloxy group) cyclobutanes of 1, the 2-, quality dosage are the 1.5- of pyromellitic acid anhydride
4.5%。
Crown ether -4 1,1- dimethyl sila -11-, quality dosage are the 1-3% of pyromellitic acid anhydride.
The Glutathione Sepharose, quality dosage are the 1-3% of pyromellitic acid anhydride.
The calcium carbonate, quality dosage are the 4-8% of pyromellitic acid anhydride.
The pyromellitic acid anhydride is commercial product, the production produced such as Zhengzhou Brian Jacks chemical products Co., Ltd
Product；The diphenyldiamine is commercial product, the product produced such as Shanghai Rong Chuan Bioisystech Co., Ltd；The 1,2-
Bis- (trimethylsiloxy group) cyclobutanes are commercial product, the product produced such as Hangzhou Pin Gao Chemical Co., Ltd.s；The 1,1-
Dimethyl sila -11- crown ethers -4 are commercial product, the product produced such as Beijing Chemical Co., Ltd. of Hua Weirui sections；Glutathione
Ago-Gel is commercial product, the product produced such as Xi'an Lanxiao Sci-Tech Co., Ltd..
The product of the present invention has the advantages that：
Elastic resin buffer layer of the present invention has good elasticity, ductility, adherence, is touched in fuel tank paint film
When hitting, the energy of collision can be buffered, sticks together inside and outside twice paint film, protection fuel tank paint film is damaged smaller；Elasticity tree
Fat has excellent dielectric property, and dielectric constant is small, is suitable as the use of oil tank of transformer paint film；Elastic resin layer contains carbonic acid
Calcium, surface is more concave-convex, convenient for being connected even closer with inside and outside twice paint film.
