After secondary cornstarch addition, respectively with 150r/min rotating speeds stirring 15min, temperature adjustment to 60-70 DEG C, for the third time with four time
After cornstarch 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, the preparation method for modifier is：
Hydroxymethyl cellulose, plant ash, peppermint oil mixing are ground 40min, are then mixed with soybean oil by a；
Sorbitol olein, rosin are mixed by B, are added calgon, are heated to 60-65 DEG C, are incubated 10min, Ran Houtian
Plus alkali lignin, acrylamide, 25min is incubated under the conditions of 82-87 DEG C；
Step a product is mixed by c with step b product, adds remaining residual components, stirs 4 hours i.e. with the speed of 2500r/min
.
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), dibutyl phthalate, polypropylene, glass fibre, calcium sulfate brilliant
Palpus, modifying agent, modified starch, give full play of the advantage of polyester, improve the stretch resistance energy of capacitor film, and improve
Its heat-resisting ability, reduces loss factor, particularly by calcium sulfate crystal whiskers, dibutyl phthalate and polyacrylic performance
Synergy significantly extend its service life, compared to the ordinary capacitor film polyester material life-span improve 48% with
On, remarkable in economical benefits.
The modifying agent that the addition present invention is prepared, not only greatly improves the heat-resisting ability of capacitor film, and energy
When enough suppressing thin film capacitor to use under the conditions of high frequency or high impulse, capacitor itself can be made by the pulse current of capacitor
Generate heat and the speed of temperature rise, so as to the significantly more efficient normal use for having ensured capacitor, the ageing resistance to capacitor film
