Abstract
The invention relates to a dot-matrix insulation powder coating for a torpedo power battery plate electrode. The coating comprises the following raw material components in parts by weight: 500-700 parts of special resin, 80-150 parts of special curing agent, 50-100 parts of pigment, 100-200 parts of filler and 30-50 parts of auxiliary agent. The powdery finished product is obtained by adopting the following steps: adding the materials into a high-speed mixer for dry mixing; then adding the mixture obtained from the former step into an extruder for melting, mixing, cooling and tabletting at the extrusion temperature of 80-90 DEG C; grinding by using a grinder; and grading, sieving and packaging. The dot-matrix insulation powder coating of the torpedo power battery plate electrode has the characteristics of high insulating property, high reaction activity and no horizontal mobility when in melting; in addition, the powder coating has excellent corrosion resistance, and can resist erosion from damp and briny environments for a long term; and the powder coating also has excellent temperature resistance, and can ensure a torpedo resists the negative effect caused by fast warming of a battery when in wartime discharge and still maintain excellent electrical insulation property when the temperature reaches above 200 DEG C. Thus, the dot-matrix insulation powder coating for the torpedo power battery plate electrode is a safety guarantee that continuous and stable current is provided for the torpedo so as to form attack.
Description
Technical field
The invention belongs to paint field, relate to insulating powder coating, especially a kind of torpedo power battery electrode plate dot matrix insulating powder coating.
Background technology
Torpedo is important antisubmarine, an anti-ship underawater ordnance of naval, and the developmental level of torpedo technique also is to weigh the important symbol of various countries naval up-to-dateness.The thrust power form of torpedo mainly contains heat power and electrokinetic force two big classes, and the energy of electric topedo is power cell, and battery is the chief component of PWR PLT on the electric topedo, and it provides the energy for propulsion electric machine.In order to improve the whole performance characterisitic of electric topedo, the torpedo production state that has modern technique in the world today has all carried out deeply and extensive studies the torpedo power battery.This wherein existing improvement to the traditional power battery has pair exploitation of new type power battery again.
Torpedo battery should satisfy following ask for something:
⑴ specific energy is high.Specific energy is meant the electric energy that battery unit mass or unit volume can be exported, and unit is respectively Wh/kg or Wh/L, and the specific energy height is that the electric energy that unit mass or unit volume can be emitted wants high.Because the quality of battery and the large percentage (being about 15%～30%) that volume accounts for torpedo total mass and TV; As do not improve the specific energy of battery as far as possible; The cell number that then in quality that torpedo allowed and volume, can carry is limited, and this will limit the speed of a ship or plane of torpedo and the raising of voyage.
⑵ specific power is big.The power of battery is meant battery under certain discharge system, the size of given energy in the unit time, and unit is W or kW.The power that the unit mass battery can provide is called specific power, and unit is W/kg or kW/kg.The battery specific power is big, representes that it can bear heavy-current discharge.In order to guarantee that the torpedo propulsion electric machine has enough power and staring torque, its rated operational current is generally at 4C (C is the capacity of battery) more than the A, and starting current is about 4 times of rated current, therefore requires the specific power of torpedo battery to want big.
⑶ long service life.Under prescribed condition, the useful life time limit of battery is called the work-ing life of this battery.Store battery usually is short-circuited because of the internal insulating layer quality problems, and capacity when not reaching specified the requirement store battery use and lost efficacy, the end of life of battery at this moment.Comprise time limit of service and life cycle the work-ing life of store battery.Time limit of service is meant the operational time of store battery, comprises the store battery shelf-time.
A silver-zinc battery cell is present electric topedo a kind of battery, particularly heavy weight torpedo with the most use.Aluminium/silver oxide cell is to be negative pole with the duraluminum, and silver suboxide is anodal, and electrolytic solution is solute with the sodium hydroxide of solid-state storage.This battery is to be that the torpedo of solvent is used primary cell with the seawater, adopts bipolarity heap formula structure, and " insulation dot matrix " separates between electrode.When battery operated, sea-water pump is treated seawater suction sodium hydroxid holder to dissolve the back and is injected battery, and the battery optimal working temp is 70 ℃～90 ℃.
China Electronics Technology Group Corporation No.18 Institute is the authoritative institution of domestic battery research, and some battery technology is also had a top standard in the whole world.Once for " Shenzhou spacecraft " important electronicss such as solar battery array, " companion star " solar battery array were provided, and some military enterprises provide the high-tech company of battery.The torpedo battery production technology that China introduces from the Soviet Union in early days is responsible for studying and producing by them.Battery electrode is used powder coating, and also in the lump from Russian import, price is extremely expensive, almost supports the price of gold.
