The present invention is achieved through the following technical solutions:
A kind of capacitor flame retardant plastics shell, is made up of following component by weight: polybutylene terephthalate (PBT) 70-
90th, abs plastics 35-45, filler 6-10, color masterbatch 1-4, Dimethyl Trimethylsilylmethylphosphonate 3-5, Corvic 10-
12nd, lubricant 6-10, fire retardant 0.2-0.4；Described fire retardant is made up of following component by weight: bentonite 2, carbamide 4,
Triethyl phosphate 1, sodium lauryl sulphate 2, modified starch 4.
Further, the weight of described polybutylene terephthalate (PBT) and abs plastics is than for 2:1.
Further, described lubricant is that sodium stearate, glycerol trioleate are mixed by 3.2:1 mass ratio.
Further, described filler be glass fibre, Talcum, any one or more combination in Muscovitum.
Further, the preparation method of described fire retardant is:
1., after uniformly mixing corn starch by the mass ratio of 100:1 with sodium phosphate, then slowly heated up heat treated
Until final temperature reaches 145 DEG C, then starch is pressurizeed, applyings pressure is 2.2mpa, after pressurize 10min, by starch and
After tetramethylolmethane presses the mixing of 3:1 mass ratio, it is ground, grinding temperature is 85 DEG C, milling time is 2h, removes Ji Wusi
Alcohol, obtains final product modified starch；
2. bentonite is added in the dodecylbenzene sodium sulfonate solution that mass concentration is 2%, after soaking 30min at 90 DEG C,
Filter, washing, dry, place into 325 DEG C of temperature lower calcination 10min；
3. stand after carbamide, triethyl phosphate, sodium lauryl sulphate uniformly being mixed at 50 DEG C, obtain material 1；
4. obtain material 2 by after uniform with the bentonite of 2. middle process for the modified starch being obtained in 1. mixing, by material 2 and ethanol
After the mixing of 2:1 mass ratio, it is ground, grinding temperature is 40 DEG C, milling time is 10min, then adds materials 1, continues
After continuous grinding 15min, remove ethanol, obtain final product required fire retardant.
The invention has the beneficial effects as follows, compared with prior art:
The plastic capacitor shell of present invention preparation, good mechanical property, anti-flammability is high, the processing characteristics of plastic capacitor shell
Well, cost and melt viscosity are low.The fire retardant that the present invention prepares has good anti-flaming function it is only necessary to little consumption is with regard to energy
Substantially play fire retardation；The mechanical strength of plastic capacitor shell will not be reduced after adding the fire retardant that the present invention prepares, lead to
The coordinated effect crossing modified starch and carbamide also improve to a certain extent the heat distortion temperature of plastic capacitor shell,
Mechanics temperature and electrical insulation capability；Each composition preferably obtains so that the fire retardant of present invention preparation is same through lot of experiments
Polybutylene terephthalate (PBT), abs plastics the compatibility good, will not migrate in plastic capacitor shell, not separate out,
It is not extracted, stability is strong；In high-temperature fusion molding and thermoforming process engineering, do not decompose, also not with other materials
React；It is uniformly dispersed, good weatherability, persistency is good, makes plastic capacitor shell have long-term anti-flammability.
