Description
Technical field
The present invention relates to cable sheath material technical field, particularly relate to a kind of excellent in cushion effect warping strength
Cable sheath material.
Background technology
Along with expanding economy, the market of cable is wide, promotes the progress of CABLE MATERIALS production technology,
CABLE MATERIALS is the most of many uses, and has special requirement, such as insulating properties, shock resistance to its performance indications
Intensity, the use index such as temperature, fire resistance all have strict requirements, constantly improve the performance of CABLE MATERIALS,
The urgent needs of economy and social development, traditional CABLE MATERIALS exist more poor fire, deflect easy fracture,
The problem such as poor mechanical property, service life are short, brings a lot of inconvenience to actually used, even threatens people
The security of the lives and property, therefore, be badly in need of change original cable material formula, improve material property, to adapt to electricity
The demand that cable market is various.
Summary of the invention
The technical problem that basic background technology exists, the present invention proposes a kind of excellent in cushion effect warping strength
Cable sheath material, has the impact strength of excellence and warping strength performance, and fire resistance is good, density

The present invention uses following preparation technology: styrene butadiene styrene block copolymer (SBS) SBS, ethylene-
Vinyl acetate copolymer eva, acrylic acid methyl ester. MA are at 70-76 DEG C of dry 30-35min, by dried benzene
Ethylene-butadiene-styrene block copolymer SBS, ethylene-vinyl acetate copolymer EVA, acrylic acid methyl ester.
MA, SBS-g-MA and EVA-g-MA add in high-speed mixer, then add in high-speed mixer calcite,
Wollastonite, blanc fixe, hollow glass microballoon, decabromodiphenyl oxide, antimony oxide, microcrystalline wax, hard
Fat acid butyl ester and anti-aging agent RD carry out mixing 5-10min and obtain mixed material, and mixing rotating speed is
900-1000rpm；Mixed material is put into inflow infiltration apparatus after extruding in double screw extruder and obtains resinifying agent
Material, wherein double screw extruder temperature is 255-265 DEG C, and screw speed is 360-365rpm, injection temperature
For 245-250 DEG C, injection pressure is 40-45MPa；Tractive quartz fibre, carbon silica fibre, polyacrylonitrile are fine
Dimension enters infiltration apparatus and is immersed in plastifying material, and draw rate is 2-4m/min, then is pulled out by carry-over pinch rolls
Obtain continuous wetting fibre；After being cooled down by continuous wetting fibre, pelletize obtains cable glass fiber reinforced plastic sheath material.
The present invention is with styrene butadiene styrene block copolymer (SBS) SBS, ethylene-vinyl acetate copolymer
EVA, acrylic acid methyl ester. MA are major ingredient, make the cohesiveness of the present invention and anti-flexibility are significantly strengthened, soft
Soft excellence, so that shock resistance of the present invention is good, coordinates and adds quartz fibre, carbon silica fibre and gather
Dralon, with above-mentioned three kinds of fibers as support, improves the rigidity of the present invention, makes the present invention have light weight
And hard, the advantages such as non-conductive, mechanical strength is high, recycles few, corrosion-resistant, and add calcite, silicon
Lime stone, blanc fixe and hollow glass microballoon, as filler, significantly improve the anti-wear performance of the present invention, and
And hollow glass microballoon or fire retardant, improve flame-proof heat-resistant performance of the present invention, also act as and alleviate product weight
Amount, improves impact strength, rigidity, hot strength, bending strength, the effect of hardness；Use decabromodiphenyl
Ether and antimony oxide coordinate as fire retardant, and antimony oxide forms association with the bromo element in decabromodiphenyl oxide
Same-action, is greatly improved the oxygen index (OI) of the present invention, makes heat-proof combustion-resistant performance of the present invention excellent；Use dipping
Fiber and resin-bonded are got up by method, decrease production stage, reduce energy consumption, cost-effective.And by
Without metal simple-substance in the present invention, without interference with cable signal, it is ensured that cable efficient operation.
