Cable jacket material containing modified polyphenylene ether resin, the weight part of its constitutive material is: modified polyphenylene ether resin 65, acrylonitrile-butadiene-styrene copolymer 22, glass fibre 3.0, vermiculite power 22, aluminium nitride 8.0, TM monex TM 1.2, acceterator TE TD 1.8, sec.-propyl distearyl acyloxy Aluminate 4.5, maleic acid zinc 2.2, two Lauryl Alcohol ester 2.4, triglyceride 1.9 and calcined loess 11.
The preparation method of the cable jacket material containing modified polyphenylene ether resin, comprises the following steps:
(1) preparation of modified polyphenylene ether resin:
Formula (weight part): polyphenylene oxide resin 15-17, terpine resin 14-18, vinylbenzene 20-30, wilkinite 1.5-3.0, MALEIC ANHYDRIDE 2.3-2.8,2,6 ditertbutylparacresol 4.5-5.0, vinyltrimethoxy silane 1.3-1.5 and linking agent TAIC 2.0-2.5;
Preparation method is as follows:
A: by the weight part of constitutive material by polyphenylene oxide resin, vinylbenzene, MALEIC ANHYDRIDE stirring reaction 3-5 hour at 90-110 DEG C;
B: add terpine resin and wilkinite stirring reaction 1-2 hour at 150-160 DEG C in step (a). by weight;
C: add 2 in step (b), 6 ditertbutylparacresols, vinyltrimethoxy silane and linking agent TAIC stirring reaction 1.0-2.0 hour at 160-180 DEG C, obtains modified polyphenylene ether resin;
(2) modified polyphenylene ether resin taking step (1) by the weight part of constitutive material remains each raw material with other, stirring at low speed 5-7 minute under normal temperature, makes to mix, then at temperature 170-180 DEG C of mixing 10-20 minute, plasticate 2-4 minute again at 170-180 DEG C, discharging.
Beneficial effect of the present invention:
The present invention adopts modified polyphenylene ether resin as major ingredient, by the modification of polyphenylene ether resin, mechanical property significantly improves, good mechanical property, there is the characteristic of low cigarette, Halogen, fire-retardant, high mechanical strength, high insulation resistance, adopt glass fibre as strengthening agent in the feed, vermiculite power and aluminium nitride are as filler simultaneously.
