Mixed 5-10min, finally in 165-185 DEG C of extruding pelletization, obtains modified poly ethylene base material；
(2) mix all with dehydrated alcohol by weight 1:2-1:3 after VTES and tetraethyl orthosilicate being mixed
Even obtaining mixed liquor, the glacial acetic acid being subsequently adding mixed liquor weight 1/10-1/15 stirs, and adds mixed liquor weight 1-
50-60 DEG C of the water of 1.5 times stirring 0.5-1h, is adjusted to neutrality by pH after cooling, add magnesium hydroxide, silicon carbide whisker 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 silicon carbide whisker-phenolic resin and be combined building optical cable sheath material.
The invention have the advantage that
One aspect of the present invention utilizes methyl phenyl silicone resin, thermoplastic phenolic resin, polyphenylene sulfide to low-density polyethylene body
It is modified that resin carries out melt blending, thus improves the anti-flammability of matrix resin, resistance to elevated temperatures and the compatibility with filler；One side
In the face of magnesium hydroxide, silicon carbide whisker powder body carry out vinyl polysiloxane coating modification, toughness and the resistance of powder body can be improved
Combustion performance, can improve again the binding ability of powder body and matrix resin by graft reaction, promotes the mechanical performance of material and stablizes
Property.By the coordination potentiation of above material, and with remaining raw material carry out compounding so as to get Cable jacket materials have concurrently
Excellent mechanical performance and fire resistance, stretch-proof, bending resistance are good, and have good high temperature resistant, ageing resistace, ring
Border adaptability is good, and service life is long, is suitably applied building cable jacket field.
