Description
Technical field
The present invention relates to a kind of electrolyte of aluminium electrolutic capacitor, more particularly to a kind of modification capacitor based on heat cure
Gel electrolyte.
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 alminium electrolytic condenser and the class of solid-state aluminum electrolytic capacitor two, go back the outlet solid gel electrolyte of half liquid half now；But it is this
Electrolyte make it that the conductance of electrolyte is low due to the presence of polymer, it is impossible to meet market needs.
The content of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art high there is provided a kind of conductance, and is electrolysed
Small modification capacitor gel electrolyte based on heat cure of liquid impedance and preparation method thereof.
In order to solve the above technical problems, technical scheme proposed by the present invention is：A kind of modification capacitor based on heat cure
Gel electrolyte, including solution systemAnd solution system, the solution systemAnd solution systemWeight mixing match
For 1:4-7:3；The solution systemThe interior nanometer Al containing mass percent 5%-20%2O3；The solution systemIncluding
The thermal initiator of 85%-95% polymerized monomer, 2%-20% crosslinking agent and 0.1%-10%, the thermal initiator includes peroxidating
The one or more of hydrogen, persulfate and hydroperoxides；The polymerized monomer is that the compound containing double bond can either be opened
Acrylic acid and its derivative that ring is polymerize.
The above-mentioned modification capacitor gel electrolyte based on heat cure, it is preferred that the crosslinking agent includes metering system
Acid -2- ethylhexyls, methacrylic acid -2- hydroxy methacrylates, methacrylic acid -2- hydroxy propyl esters, the one of methyl methacrylate
Plant or a variety of；The polymerized monomer includes acrylic acid, polyacrylic acid, methyl acrylate, isobutyl acrylate, methacrylic acid second
The one or more of ester.
The above-mentioned modification capacitor gel electrolyte based on heat cure, it is preferred that the solution systemAlso include 45%-
65% main solvent, 15%-25% secondary solvent, 8-25% main solute, 2%-5% secondary solute and 0.5%-3% additive；
The main solvent can be ethylene glycol, and the secondary solvent includes one kind or many of water, glycerine, propane diols and BDO
Kind.
The above-mentioned modification capacitor gel electrolyte based on heat cure, it is preferred that the main solute includes succinic acid, penta
Diacid, adipic acid, ammonium adipate, ammonium octanedioic acid, ammonium azelate, ammonium sebacate, 1,7- ammonium sebacates, isosebacic acid ammonium, alkyl

So as to be prevented effectively from the undesirable conditions such as the prominent, valve opening in capacitor bottom.
A kind of compound method of the modification capacitor gel electrolyte based on heat cure, comprises the following steps：1）1）Prepare
Solution system, by main solvent, secondary solvent and nanometer Al2O3With ultrasonic wave it is well mixed after be heated to 90-120 degrees Celsius, plus
Solute and secondary solute are become owner of, 30-60 minutes are incubated at a temperature of 110-140 degrees Celsius, 100 degrees Celsius is cooled to and adds addition
Agent, and it is cooled to room temperature；
2）Prepare solution system, monomer used, crosslinking agent are sequentially added in liquid pool, after being mixed evenly, heat is added
Initiator, is stirred 30-50 minutes；
3）By solution systemAnd solution systemAccording to 1:4-7:3 proportioning is mixed and stirred for 10-30 minutes, obtains uniform, clear
Clear solution；
4）By step 3）Obtained uniform, clarification solution is placed in oven for curing 20 minutes that temperature is 65 DEG C ~ 105 DEG C -4 small
When, obtain the electrolyte of gel state.
The thermal initiator that the present invention is used is water solubility, inorganic, middle warm type, can uniformly be dissolved into the molten of electrolyte
In agent, uniform gel state electrolyte can be obtained, other types initiator is effectively prevent and is unable to uniform dissolution to electrolyte
The partial polymerization that is brought in solvent is insufficient, the short-circuit equivalent risk of capacitor internal.
The present invention is by the way of polymerisation in solution, and thermal initiator is uniformly distributed in solvent, hot in case of heating
Initiator itself is decomposed, fracture, forms two initial radicals, is then triggered monomer radical to occur polymerisation, is obtained
The ratio of viscosities polymerisation in bulk of the polymerization system arrived is low, and mixing and radiating are easier, and production operation and temperature are all easily controllable, also
Using the evaporation of solvent to exclude heat of polymerization.
Conventional organic peroxide polymerization initiator（For example：α, α `- azodiisobutyronitriles）Decomposed at its own
Reaction can produce nitrogen and be solidified with the state in gel internal package bubble while producing free radical, due to bubble
In the presence of, it is difficult to obtain uniform gel macromolecule.
In the present invention, initiator molecule contains weak bond, and two primary group of free radicals are produced by heat resolve, primary free
Base then triggers monomer to produce free radical so as to occur chain initiation reaction generation polymerisation to form gel state.
Initiation is divided into the following steps in polymerization process:(1) initiator resolves into initial radical in aqueous phase；(2) it is initial
Free radical triggers polymerization in aqueous phase (electrolyte can all have the presence of water in process for preparation or even after the completion of preparation)；(3)
Initial radical monomer in aqueous phase is diffused into emulsion particle or in monomer droplet；(4) free radical triggers poly- in emulsion particle
Close, generate high molecular polymer so that emulsion particle is constantly grown up.
First stage, emulsion particle generated the phase one by one.From starting to trigger polymerization, until the micella of emulsifying agent formation disappears, gather
Close increasing rate.The free radical produced in aqueous phase is diffused into micella, is triggered, increased, and constantly forms emulsion particle, simultaneously
Monomer can also trigger polymerization, absorption emulsifier molecules formation emulsion particle in aqueous phase.It is solubilized with proceeding for polymerization is triggered
The continuous nucleation of micella, emulsion particle is on the increase or increased, when monomer conversion 15% or so, and micella all disappears, and does not re-form new
Emulsion particle, later trigger polymerization completely in emulsion particle carry out.
Second stage constant speed phase one by one.After micella disappears, polymerization enters second stage.Chain triggers, increased and terminating reaction
Continue to carry out in emulsion particle, drop still plays a part of warehouse, constantly supplies monomer to emulsion particle.Monomer concentration in emulsion particle
Keep constant, add that latex grain number is constant, the rate of polymerization in this stage is also substantially certain.Monomer conversion is up to 50% or so, liquid
Drop all disappears, and monomer fully enters emulsion particle, starts to be transferred to the phase III.
Reduction of speed phase one by one phase III.Is made up of monomer and polymer two parts in emulsion particle, the free radical in water can be with
Emulsion particle is continued to diffuse into trigger or terminate, but monomer, again without supplement source, rate of polymerization is by with monomer concentration in emulsion particle
Reduce and reduce, until polymerization is completed.
In the present invention, nanometer Al2O3The transfer ability of gel polymer electrolytes ion can be improved.One side nanometer
Al2O3By having an effect for Surface L ewis acid and copolymer chain and ammonium salt, weaken in polymer chain and ammonium salt atom and ammonium from
Active force between son, discharging more ammonium ion improves its transfer ability；Another convenience, nanometer Al2O3It is used as polymerization
Crosslink part on thing chain, reduces the crystallinity of polymer chain, strengthens the sub-chain motion of polymer, gathers so as to improve gel
The transport number of polymer electrolyte ion and the electrical conductivity of ion, the electrical conductivity of doping gel capacitor electrolyte of the invention can
Reach, than no addition nanometer Al2O3Gel electrolyte electrical conductivity improve nearly 50%.
