PH to 10.2 obtains basic hydroxide group apatite reaction solution；
(2) ethyl alcohol that its quality 45% is added into basic hydroxide group apatite reaction solution obtained above obtains after mixing evenly
To ethanol；
(3) added into ethanol obtained above its quality 2.5-2.8% hexachlorocyclotriph,sphazene and 1.2-1.5% to acetyl
Amino-phenol after mixing evenly, then adds catalyst, is heated to 80 DEG C, is stirred to react 2.5 hours with 180r/min revolving speed, so
1 hour is stood afterwards, obtains reaction solution；
(4) reaction solution obtained above is used into ultrasonication 4-6min, then heat preservation stands 2 under 88 DEG C of heating water baths again
Hour, high speed rotation centrifugation is then carried out, cleaning obtains solids after drying, under nitrogen protection by obtained solids,
It is calcined 2.5 hours at being 335-340 DEG C in temperature, to get modified hydroxylapatite nano-powder after cooled to room temperature.
Further, the calcium source and phosphorus source are weighed according to calcium/phosphorus atoms than 1.55.
Further, the lye is the sodium hydroxide solution that concentration is 1.25mol/L.
Further, the catalyst is Anhydrous potassium carbonate.
Further, the ultrasonic frequency is 40kHz, power 750W.
Further, the tributyl citrate weight is less than the 10% of dicyclohexyl phthalate quality.
The utility model has the advantages that the present invention reasonably matches plastic capacitor shell each component by a large amount of experimental study
Than the plastic capacitor shell of preparation, good mechanical property, processing performance is good, has good ageing-resistant performance good, has excellent
Thermal stability, the present invention passes through a large number of experiments the study found that by adding a certain amount of hydroxy phosphorus Calx, is merely able to slightly
The ageing-resistant performance of the raising plastic capacitor shell of degree influences the anti-acoustic capability of plastic capacitor shell less, to lead to electricity
When container work, noise is larger, and therefore, the present invention obtains changing in the present invention to hydroxy phosphorus Calx by a large number of experiments
Property processing technical solution, through the invention in technical solution the obtained modified hydroxyl of processing is modified to hydroxy phosphorus Calx
Have in apatite nano-powder architectural characteristic and greatly change, gathers so that modified hydroxylapatite nano-powder is used in capacitor
It can preferably be combined with PP matrix in Acrylic plastic shell, form stable network structure, thus greatly
The ageing-resistant performance and resistance to ultraviolet radiation energy for improving polypropylene plastics shell, extend capacitor polypropylene plastics shell
Service life reach certain noise reduction effect meanwhile, it is capable to effectively carry out a degree of barrier to the propagation of sound.
