Description

A kind of calcium sulfate whisker modified oil resistant building optical cable sheath material and preparation method thereof
Technical field
The present invention relates to optical fiber jacket field of material technology, particularly relate to a kind of calcium sulfate whisker modified oil resistant building optical cable With sheath material and preparation method thereof.
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
The object of the invention is contemplated to make up the defect of prior art, it is provided that one has good fire retardant performance and machine concurrently Calcium sulfate whisker modified oil resistant building optical cable sheath material of tool performance and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of calcium sulfate whisker modified oil resistant building optical cable sheath material, it is to be prepared by the raw material of following weight parts:
Low Density Polyethylene 80-100, methyl phenyl silicone resin 3-5, acrylonitritrile-styrene resin 2-4, magnesium hydroxide 4-6, Tetraethyl orthosilicate 0.5-1, tributyl citrate 0.5-1, VTES 1.5-2.5, triphenyl phosphate 3-5, sulfur Acid calcium pyroborate 2-4, antioxidant 1010 0.3-0.5, polypropylene wax micropowder 0.5-1.
The preparation method of a kind of calcium sulfate whisker modified oil resistant building optical cable sheath material, comprises the following steps:
(1) weigh raw material by weight, first Low Density Polyethylene and methyl phenyl silicone resin are added mixing roll 50-60 DEG C jointly high Speed is blended 10-15min, is subsequently adding acrylonitritrile-styrene resin and tributyl citrate 100-110 DEG C high 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, calcium sulfate crystal whiskers 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 200-220 DEG C, Obtain calcium sulfate whisker modified oil resistant building optical cable sheath material.
The invention have the advantage that
One aspect of the present invention utilizes methyl phenyl silicone resin, acrylonitritrile-styrene resin to low-density polyethylene body resin Carry out melt blending modified, thus improve the anti-flammability of matrix resin, oil resistivity and the compatibility with filler;On the one hand to hydrogen-oxygen Change magnesium, calcium sulfate crystal whiskers powder body carries out vinyl polysiloxane coating modification, can improve toughness and the fire resistance of powder body, again The binding ability of powder body and matrix resin can be improved by graft reaction, promote mechanical performance and the stability of material.By with The coordination potentiation of upper material, and with remaining raw material carry out compounding so as to get Cable jacket materials have excellent machine concurrently Tool performance and fire resistance, stretch-proof, bending resistance are good, and have good oil resistance and chemical stability, and environment is fitted Answering property is good, is suitably applied building cable jacket field.
