Description
Technical field
The present invention relates to a kind of aluminium electrolutic capacitor, particularly relate to a kind of aluminium electroloysis based on heat cure gel electrolyte electricity
Container and preparation method thereof.
Background technology
Electrolyte is one of important composition of aluminium electrolutic capacitor, and aluminium electrolutic capacitor can be divided into liquid according to electrolyte form
State aluminium electrolutic capacitor and solid-state aluminum electrolytic capacitor two class.The electrolyte that liquid aluminum electrolytic capacitor is used is by Organic substance group
Becoming, during the use of capacitor, owing to capacitor heating itself or ambient temperature are high, electrolyte is easily generated gas, thus
Form excessive vapour pressure, cause capacitor to explode, and liquid electrolyte easily corrodes aluminum hull, causes leakage, liquid
There is potential safety hazard in aluminium electrolutic capacitor so that its preparation process controls the strictest；Solid-state aluminum electrolytic capacitor is due to work
Voltage low (less than 200 V), therefore its range of application receives strict restriction.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, it is provided that a kind of safety is high, it is enough to have
The aluminium electrolutic capacitor based on heat cure gel electrolyte of running voltage and preparation method thereof.
For solving above-mentioned technical problem, the technical scheme that the present invention proposes is: a kind of based on heat cure gel electrolyte
Aluminium electrolutic capacitor, including outer shell-and-core bag, described core bag seals in the enclosure；Described core bag is internal and core bag and shell it
Between be formed with gel electrolyte, described gel electrolyte is solution systemAnd solution systemGather under the initiation of UV light
Close the gel macromolecular compound obtained, described solution systemAnd solution systemMixing match be 1:4-7:3；Described
Solution systemPolymerization monomer, the cross-linking agent of 2%-20% and the thermal initiator of 0.1%-10%, described thermal initiation including 85%-95%
Agent includes one or more of hydrogen peroxide, persulfate and hydroperoxides；Described polymerization monomer is the chemical combination containing double bond
Thing or open loop can carry out acrylic acid and the derivant thereof be polymerized.
The thermal initiator that the present invention uses is water solublity, mineral-type, middle warm type, can be dissolved into the molten of electrolyte uniformly
In agent, uniform gel state electrolyte can be obtained, effectively prevent other types initiator can not uniform dissolution to electrolyte
The partial polymerization brought in solvent is insufficient, the short-circuit equivalent risk of capacitor internal.
The present invention uses the mode of polymerisation in solution, and thermal initiator is distributed in solvent uniformly, in case of heating heat
Initiator self is decomposed, fracture, forms two initial radical, then trigger monomer free radical generation polyreaction,
The ratio of viscosities polymerisation in bulk of the polymerization system arrived is low, mixes and heat radiation is easier, and production operation and temperature are the most easily controllable, also
The evaporation of available solvent is to get rid of heat of polymerization.
Conventional organic peroxide polymerization initiator (such as: α, α `-azodiisobutyronitrile) is decomposed at himself
Reaction can produce nitrogen and solidify with the state at gel internal package bubble, due to bubble while producing free radical
Exist, it is difficult to obtain uniform gel macromolecule.
In the present invention, initiator molecule contains weak bond, produces two primary group of free radicals, primary group of free radicals by heat resolve
Then trigger monomer produces free radical thus chain initiation reaction generation polyreaction occurs thus forms gel state.As shown in Figure 1
The schematic diagram of free radical is become for persulfate initiator heat resolve.
In polymerization process, initiation is divided into the following steps: (1) initiator resolves into initial radical in aqueous phase；(2) initial
Free radical causes polymerization in the aqueous phase existence of water (electrolyte even all can have after having prepared in process for preparation)；(3)
Initial radical monomer in aqueous phase is diffused in emulsion particle or in monomer droplet；(4) free radical causes polymerization in emulsion particle,
Generate high molecular polymer so that emulsion particle is constantly grown up.
First stage emulsion particle one by one generates the phase.It is polymerized from starting to cause, until the micelle that emulsifying agent is formed disappears, polymerization
Increasing rate.The free radical produced in aqueous phase diffuses in micelle, carries out causing, increasing, constantly forms emulsion particle, simultaneously water
Mutually middle monomer can also cause polymerization, absorption emulsifier molecules to form emulsion particle.Along with causing proceeding of polymerization, solubilising glue
Restrainting continuous nucleation, emulsion particle is on the increase or increases, and when monomer conversion about 15%, micelle all disappears, and is no longer formed new
Emulsion particle, causes polymerization to carry out in emulsion particle completely later.
The second stage constant speed phase one by one.After micelle disappears, polymerization enters second stage.Chain causes, increases and terminates reaction
Continuing to carry out in emulsion particle, drop still plays a part warehouse, constantly to supply monomer to emulsion particle.Monomer concentration in emulsion particle
Keeping constant, add that emulsion particle number is constant, the rate of polymerization in this stage is the most certain.Monomer conversion reaches about 50%, liquid
Dripping and all disappear, monomer fully enters emulsion particle, starts to proceed to the phase III.
The reduction of speed phase one by one phase III.Being made up of monomer and polymer two parts in emulsion particle, the free radical in water is permissible
Continuing to diffuse into emulsion particle cause or terminate, but monomer is again without supplementing source, rate of polymerization is by with monomer concentration in emulsion particle
Reduce and reduce, until being polymerized.
