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, blanc fixe stirring 2-4h,
Filter, be dried, grind 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 perfluoropolyether-modified corrosion-resistant building optical cable sheath material.
The invention have the advantage that
One aspect of the present invention utilizes methyl phenyl silicone resin, PFPE and glycidyl methacrylate to low density polyethylene
It is modified that alkene matrix resin carries out melt blending, thus improves the anti-flammability of matrix resin, decay resistance and compatible with filler
Property；On the one hand magnesium hydroxide, barite powder are carried out vinyl polysiloxane coating modification, can improve powder body toughness and
Fire resistance, can improve again the binding ability of powder body and matrix resin by graft reaction, promotes the mechanical performance of material with steady
Qualitative.By the coordination potentiation of above material, and with remaining raw material carry out compounding so as to get Cable jacket materials hold concurrently
Having excellent mechanical performance and a fire resistance, stretch-proof, bending resistance are good, and have good corrosion-resistant, water resistance, make
Using the life-span long, environmental suitability is strong, is suitably applied building cable jacket field.
