Description
Technical field
The present invention relates to optical fiber jacket field of material technology, particularly relate to a kind of mildew and insect proof building light for basement
Cable 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
Mildew and insect proof building optical cable sheath material for basement of tool performance and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of mildew and insect proof building optical cable sheath material for basement, it is to be prepared by the raw material of following weight parts:
Low Density Polyethylene 80-100, methyl phenyl silicone resin 3-5, magnesium hydroxide 4-6, tetraethyl orthosilicate 0.5-1, vinyl three
Ethoxysilane 1.5-2.5, triphenyl phosphate 3-5, prallethrin 0.1-0.15, antioxidant 1010 0.3-0.5, Nanometer Copper
0.5-1, bamboo tar 1-2, three red oil 0.1-0.15, medical stone powder 2-4.
The preparation method of a kind of mildew and insect proof building optical cable sheath material for basement, 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 medical stone powder, prallethrin, 100-110 DEG C of high speed of bamboo tar are blended 5-10min, finally
In 165-185 DEG C of extruding pelletization, obtain 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, Nanometer Copper stirring 2-4h, mistake
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 180-200 DEG C,
Obtain the mildew and insect proof building optical cable sheath material for basement.
The invention have the advantage that
One aspect of the present invention utilizes methyl phenyl silicone resin that low-density polyethylene body resin carries out melt blending modification, thus
Improve the anti-flammability of matrix resin, pliability and the compatibility with filler；On the one hand magnesium hydroxide, Nanometer Copper powder body are carried out second
Thiazolinyl polysiloxanes coating modification, can improve toughness and the fire resistance of powder body, again can by graft reaction improve powder body with
The binding ability of matrix resin, promotes mechanical performance and the stability of material.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, stretch-proof, anti-
Good bandability, and there is good mildew and insect proof performance, sanitation performance is good, and service life is long, is suitably applied building underground
Cable jacket field, room.
