28 DEG C are cooled to, then using 420W microwave treatment 30s, room temperature is naturally cooled to；The diatomite uses quality in advance
Concentration be 6.98% sodium hydroxide solution soak 45 minutes after, washing, filtering, drying and processing obtains final product；
The mica powder is by pretreatment：By mica powder and the titanate esters and propylene glycol methyl ether acetate mixture of its quality 50%
It is uniform admixed together, after being ground 1 hour, filtering, washing, drying, you can, the titanate esters and propylene glycol monomethyl ether vinegar
Titanate esters and propylene glycol methyl ether acetate press 3 in acid ester mixtures:1 mass ratio is mixed；
The polyvinyl alcohol is by pretreatment：Polyvinyl alcohol is heated to 94 DEG C, softening is reached, then add the sweet of its quality 2.3%
Oil and Corn Starch Blends, after stirring, 113 DEG C are increased to by temperature, after being stirred 30 minutes with 250r/min speed, with
The speed of 19 DEG C/2s is quickly cooled to 18 DEG C, after being incubated 10 minutes, then is warming up to 118 DEG C, insulation 10 with the speed of 20 DEG C/2s
After minute, room temperature is naturally cooled to, obtained final product；
The bamboo powder is by pretreatment：It is added in water, after hotting plate 40 minutes, filtering is added to the temperature that mass concentration is 8.26%
Spend after being soaked 20 minutes in the sodium hydroxide solution for 5 DEG C, filtering, washing, drying is obtained final product；
The adjuvant is that Purple Perilla Seed Oil presses 1 with camellia seed oil:4 mass ratios are at 78 DEG C with 550r/min rotating speed mixed at high speed
Form within 35 minutes.
A kind of preparation method of electric capacity impregnating agent prepared by modipied natural apatite, including：
（1）The linseed oil of corresponding weight portion is added in 80-90 DEG C of a mixing bowl, the water content of linseed oil is detected, if
It is unqualified, dewater treatment is carried out to it, it is standby when μ g/ml in water content≤20 in linseed oil；
（2）Ricinoleic acid, polyvinyl alcohol, the expoxy propane of corresponding weight portion are weighed, are sequentially added in a mixing bowl, be heated to 170 DEG C,
After being stirred 25 minutes with 100r/min speed, sealing is closed to stand 10 minutes；
（3）Bamboo powder, the hexadecyl metrhacrylate of corresponding weight portion are weighed in proportion, individually after mixing, are stirred 10 minutes, deblocking
A mixing bowl, bamboo powder, hexadecyl metrhacrylate mixture is added in a mixing bowl, by temperature adjustment to 82 DEG C, with 120r/
Min speed is stirred 25 minutes；
（4）Mica powder, glass dust, the adjuvant of corresponding weight portion are weighed, is added in a mixing bowl successively, by temperature adjustment to 60
DEG C, stirred 30 minutes with 100r/min speed, naturally cool to room temperature and obtain final product.
The present invention by substantial amounts of experimental study, by linseed oil having carried out substantial amounts of research and treatment is modified, always
Bear the method for modifying of linseed oil optimal when preparing electric capacity impregnating agent so that by the modified linseed oil of the present invention
