When existing thin film capacitor is used under the conditions of high frequency or high impulse, capacitor itself can be made by the pulse current of capacitor
Generate heat and temperature rise, cause the problems such as increase of self-healing point, pressure reduction.
The content of the invention
It is an object of the invention to provide a kind of capacitor film high temperature resistance polyester material, real by the following technical programs
It is existing：
A kind of capacitor film high temperature resistance polyester material, is made up of following component by weight：Polyester 128-130, poly- third
Acrylamide 18-25, polytetrafluoroethylene (PTFE) 28-30, polyhydroxyalkanoate 1-4, polyethylene glycol 4-6, glass fibre 8-12, antifungin
Whisker 1-5, auxiliary agent 0.5-1, modified starch 5-8；The auxiliary agent is made up of following component by weight：Calcium silicates 5, methylol
Cellulose 2, Nano chitosan 1.
Further, the polyester is that PET presses 100 with polybutylene terephthalate:3 mass
Ratio is mixed.
Further, the glass fiber single filament is a diameter of 15-18 μm, silane of the glass fibre through its quality 5%
Coupling agent treatment, the silane coupler are VTES.
Further, the modified starch is made up of following component by weight：Glutinous rice starch 32, tapioca 2, receive
Rice silica 1, nano diatomite 3, its preparation method is：Zinc sulfate is pressed into 3 with water:After the mixing of 120 mass ratios, Ran Houtian
Plus nano silica and glutinous rice starch, after stirring, are heated to 58-60 DEG C, are incubated 15min, then add nanometer diatom
Soil, is stirred after 30min with 100r/min rotating speeds, adds tapioca in four times, every time 1 weight portion of addition, and for the first time with the second
After secondary tapioca addition, respectively with 150r/min rotating speeds stirring 15min, temperature adjustment to 60-70 DEG C, for the third time with four time
After tapioca addition, 15min is stirred with 250r/min rotating speeds respectively, then temperature adjustment to 75-80 DEG C is ground
20min, after standing 1h, filters, washs, be dried at 100 DEG C, you can.
Further, it is characterised in that the auxiliary agent preparation method is：
1. press 1:After calcium silicates is mixed with polyethylene glycol by 1 mass ratio, 40min is ground, is then filtered, carried out using clear water
Surface clean, drying, to place into and calcine 10min at 280 DEG C, be quickly cooled to room temperature, obtain material 1；
2. after the acrylic acid of hydroxymethyl cellulose and its quality 5%, 2% acrylamide, 0.5% nano silicon being mixed,
At 98 DEG C, 30min is stirred with 150r/min rotating speeds, after insulation stands 1h, material 2 is obtained；
3. it is material 1 is uniform admixed together at 60 DEG C with Nano chitosan with material 2, obtain final product required auxiliary agent.
The invention has the beneficial effects as follows：The capacitor film polyester material each component collective effect of the present invention, with polyester
Primary raw material, is aided with polyacrylamide, polytetrafluoroethylene (PTFE), polyhydroxyalkanoate, polyethylene glycol, glass fibre, antifungin brilliant
Palpus, auxiliary agent, modified starch, give full play of the advantage of polyester, improve the stretch resistance energy of capacitor film, and improve which
Heat-resisting ability, reduces loss factor, particularly by the performance of magnesium borate crystal whisker, polyhydroxyalkanoate and polyethylene glycol
Synergy significantly extends its service life, improves more than 50% compared to the ordinary capacitor film polyester material life-span,
Remarkable in economical benefits.
Modified starch prepared by the present invention is acted synergistically with remaining raw material, can improve thin-film capacitor to a certain extent
Scope, and leak resistance resistance can be improved, the anti-breakdown performance of enhanced film electric capacity, and then making for capacitor can be improved
With the life-span, capacitor frequency characteristic is enabled to more preferably, dielectric loss is lower such that it is able to guarantee that signal, will not in transmission
There is too big distortion situation to occur, greatly improve the quality of capacitor.
The auxiliary agent that the addition present invention is prepared, greatly improves the heat-resisting ability of capacitor film, and can suppress
When thin film capacitor is used under the conditions of high frequency or high impulse, capacitor self-heating can be made by the pulse current of capacitor and
The speed of temperature rise, so as to the significantly more efficient normal use for having ensured capacitor.

After stirring, 58-60 DEG C is heated to, is incubated 15min, then adds nano diatomite, 30min is stirred with 100r/min rotating speeds
Afterwards, add tapioca in four times, every time 1 weight portion of addition, after the addition of for the first time with second tapioca, respectively with
150r/min rotating speeds stir 15min, temperature adjustment to 60-70 DEG C, after for the third time with four tapioca adds, respectively with
250r/min rotating speeds stir 15min, and then temperature adjustment to 75-80 DEG C is ground 20min, after standing 1h, filter, wash,
It is dried at 100 DEG C, you can.
5. a kind of capacitor film high temperature resistance polyester material according to claim 1, it is characterised in that the auxiliary agent system
Preparation Method is：
1. press 1:After calcium silicates is mixed with polyethylene glycol by 1 mass ratio, 40min is ground, is then filtered, carried out using clear water
Surface clean, drying, to place into and calcine 10min at 280 DEG C, be quickly cooled to room temperature, obtain material 1；
2. after the acrylic acid of hydroxymethyl cellulose and its quality 5%, 2% acrylamide, 0.5% nano silicon being mixed,
At 98 DEG C, 30min is stirred with 150r/min rotating speeds, after insulation stands 1h, material 2 is obtained；
3. it is material 1 is uniform admixed together at 60 DEG C with Nano chitosan with material 2, obtain final product required auxiliary agent.
