Meter is made up of following component：Sodium polyacrylate 2-6, methyl ester levulinate 5-9, maltol 1-4；It is the modified salad oil, poly- different
Butylene, the mass ratio of latent curing agent are 15:5:1.
Further, the modified salad oil is made up of following component by weight：Fructus Zanthoxyli oil 2, canola oil 1, Fructus Vitis viniferae
Seed oil 3, Oleum Ricini 12, butyrolactone 0.2,2- propyl group-thiophene 0.1, Methyl cellulose 0.3, its preparation method is：By Fructus Zanthoxyli oil, mustard
Caul-fat, Oleum Vitis viniferae, Oleum Ricini are admixed together by respective weight portion, are heated to 68-72 DEG C, are stirred with 180r/min rotating speeds
After 20min, add butyrolactone and methylcellulose, after continuing stirring 25min, add 2- propyl group-thiophene, continue to stir 35min
Afterwards, it is incubated, stands 20min, then through deacidification, removing impurities, dephosphorization treatment, modified salad oil needed for obtaining final product.
Further, the plasticizer is glyceryl tripropanoate.
Further, latent curing agent is made up of following component by weight：Melmac 5, phenyl glycidyl
Glycerin ether 0.1, isooctyl acid 1.7, calcium sulfate 1.5, benzoin ethyl ether 0.1.
Further, the Oleum Ricini is through pretreatment：Cold preservation 3-4h at Oleum Ricini is firstly placed on -8 DEG C, then with 10
DEG C/speed of 50s is warming up to 92 DEG C, 30min is incubated, then -8 DEG C is cooled to the speed of 10 DEG C/30s, be incubated 10min, then,
Clear-cutting forestland is to room temperature, you can, by the pretreatment to Oleum Ricini, the viscosity of Embedding Material of the present invention can be reduced, which is improved
Levelability.
Further, the preparation method of the high-performance metal membrane capacitance Embedding Material, comprises the following steps：
（1）The modified salad oil of corresponding weight, glutamic acid, polyvinyl alcohol resin, poly- isobutyl are added in 55-58 DEG C of a mixing bowl
Alkene, is stirred with 250r/min rotating speeds；
（2）The epoxy soybean oil of corresponding weight, Oleum Ricini, mica powder, starch are weighed, a mixing bowl for stirring is added slowly to
In, regulation mixing speed is 200r/min, continues stirring；
（3）Weigh the soybean lecithin of corresponding weight, plasticizer, auxiliary agent to be added in a mixing bowl for stirring, continue with
200r/min rotating speeds are stirred 1 hour；
（4）The latent curing agent for weighing corresponding weight is added in a mixing bowl for stirring, and adjusts mixing speed to 800-
1000r/min, persistently stirs 2-3 hours, naturally cools to room temperature, you can, sealing is kept in dark place, and storage temperature is less than 30
℃。
Metallized membrane capacitance embedding materials'use post cure condition of the present invention is preferably 44 DEG C at 42-46 DEG C, and is matched somebody with somebody
Conjunction ultraviolet light UVA irradiation 32-38s, preferred 35s, the present invention coordinate ultraviolet light UVA irradiation 35s at 44 DEG C, and solidification is most smooth,
Solidfied material is best in quality.
Beneficial effect of the present invention：Embedding Material of the present invention has an excellent electrical properties, moisture resistance, flowing domestic animal, thermostability and resistance to
It is cold good, with good impact resistance, excellent dielectric insulation performance, ensure that the steady of metallization film capacitor electrical property
It is fixed, can abundant added metal membrane capacitance gap, will not to the generation harmful effect of metallization film capacitor service behaviour,
It is fabulous to the embedding using effect of the electric elements under the conditions of miniaturization, lightweight, shock resistance；The present invention is by using modified color
Draw oil to coordinate the coordinated effect of polyisobutylene, soybean lecithin and polyvinyl alcohol resin, enable to the tough modeling of Embedding Material
Property it is high, embrittlement is difficult under low temperature, water-tolerant, cure shrinkage are little, without planted agent when anti-seismic performance and heatproof rush good ability, solidification
Power, it is to avoid the generation of cracking phenomena, cold-resistant thermal circulation performance are very superior；The auxiliary agent collaboration prepared by adding the present invention is matched somebody with somebody
Close the effect of other compositions, it is possible to increase the radiating when heat conductivity of solidfied material, more conducively capacitor work.
