(2) by weight after ten difluoro heptyl propyl trimethoxy silicanes, VTES and tetraethyl orthosilicate being mixed
Measuring to mix homogeneously with dehydrated alcohol than 1:2-1:3 and obtain mixed liquor, the glacial acetic acid being subsequently adding mixed liquor weight 1/10-1/15 stirs
Mix uniformly, add 50-60 DEG C of the water stirring 0.5-1h of mixed liquor weight 1-1.5 times, after cooling, pH is adjusted to neutrality, adds hydrogen
Magnesium oxide, aluminum nitride powder stirring 2-4h, filters, is dried, grinds uniformly, obtain modified powder；
(3) first the modified powder in (2), the modified poly ethylene base material in (1) are blended at a high speed 10-15min with triphenyl phosphate,
It is subsequently adding remaining raw material and 10-20min is blended at a high speed, carry out extruding pelletization finally by double screw extruder in 180-220 DEG C,
Obtain high-lubrication wear-resisting building optical cable sheath material.
The invention have the advantage that
One aspect of the present invention utilizes methyl phenyl silicone resin, Oleum Ricini that low-density polyethylene body resin is carried out melt blending to change
Property, thus improve the anti-flammability of matrix resin, lubricity and the compatibility with filler；On the one hand to magnesium hydroxide, aluminum nitride powder
Body carries out vinyl polysiloxane coating modification, can improve toughness and the fire resistance of powder body, can be changed by graft reaction again
Kind powder body and the binding ability of matrix resin, promote mechanical performance and the stability of material.By the coordination potentiation of above material
Effect, and with remaining raw material carry out compounding so as to get Cable jacket materials have excellent mechanical performance and fire resistance concurrently,
Stretch-proof, bending resistance are good, and have high-lubricity, high-wearing feature, good endurance, are suitably applied building cable jacket neck
