Background technology
Along with the development of telecommunications, the use of optical cable is more and more universal, and this proposes also to the structure of optical cable and performance
New requirement.Particularly domestic premises optical cable is as obtaining the product greatly developed in recent years, and demand is huge, Communication ray used
Cable is close with the safety and health issue concerns of people, therefore requires higher to the fire retardant performance of optical cable.The most conventional
Cable jacket mainly uses common polythene material, and not only case hardness is not enough, easily produce abrasion, and flame-proof environmental protection performance
, there is great potential safety hazard in difference.
For improving the fire protecting performance of optical cable, promote its safety in utilization, often in polyethylene, add bittern-free flame-proof material such as
Magnesium hydroxide is to reach flame retardant effect.But the substantial amounts of mineral-filled decline causing macromolecular material mechanical performance, serious shadow
Ring its serviceability.CN201010293614 discloses a kind of Halogen, presses down cigarette, the preparation method of flame retardant type plastic optical fiber sheath,
Use two-step method that flame retardant of magnesium hydroxide is carried out surface modification, by promoting the affinity reduction of fire retardant and base polyethylene
Add the fire retardant impact on the mechanical property of materials.But this method is to the mechanical performance of sheath material, especially bendability
Energy, tensile property etc. are improved limited, and still there is wearability, the situation of anti-flammability deficiency, it is difficult to meet domestic premises light
The demand of cable wiring.
Summary of the invention

Speed is blended 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 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 LNBR modification high flexibility building optical cable sheath material.
The invention have the advantage that
One aspect of the present invention utilizes methyl phenyl silicone resin, titanate coupling agent DN-201, lignocellulose, LNBR
Low-density polyethylene body resin is carried out melt blending modified, thus improve the anti-flammability of matrix resin, pliability and with fill out
The compatibility of material；On the one hand magnesium hydrate powder is carried out vinyl polysiloxane coating modification, the toughness of powder body can be improved
And fire resistance, can be improved again the binding ability of powder body and matrix resin by graft reaction, promote material mechanical performance and
Stability.By the coordination potentiation of above material, and with remaining raw material carry out compounding so as to get Cable jacket materials
Have excellent mechanical performance and fire resistance concurrently, and there is high-flexibility energy, stretch-proof, bending resistance excellence, it is easy to processing,
Range is wide, is suitably applied building cable jacket field.
