Description
Technical field
The present invention relates to a kind of fire proofing, more particularly to a kind of covering material of data wire, belong to macromolecular material skill
Art field.
Background technology
Data wire (data cable), its effect reaches data transfer or logical to connect mobile device and computer
Letter purpose.Popular point says, exactly connects computer and mobile device for transmitting the path instrument of the files such as video, the tinkle of bells, picture.
Now, with the development that electron trade is maked rapid progress, data wire has become part indispensable during we live.It is existing
Data wire on the one hand in use because easy heat radiation does not cause heating to produce empyreumatic taste, or even burning, on the other hand using
In often block abrasion because of friction or by tables and chairs, lead to not use.
The content of the invention
The purpose of the present invention is there are the problems referred to above for existing technology, it is proposed that a kind of high temperature resistant, good flame retardation effect
Data wire covering material.
The purpose of the present invention can be realized by following technical proposal：A kind of covering material of data wire, described cladding
Material includes following constituent：
Polyvinyl chloride：100 parts
TPUE 90A：20-40 parts
Ethylene-vinyl acetate copolymer：10-20 parts

Processing aid：3-10 parts.
Relatively poor for the wearability of the covering material of data wire in prior art, high-temperature behavior is poor, anti-flammability compared with
It is low, and then the service life of impact data wire, it is appropriate that the present invention has selected the present invention to add in matrix resin polyvinyl chloride
TPUE 90A, ethylene-vinyl acetate copolymer, while adding plasticizer, fire retardant, compatilizer, shock resistance
Modifying agent, metal chlorination salt etc., especially metal chlorination salt plus in membership and resin hydrogen bond action, mainly metal ion
Plus membership reduce degree of crystallinity, increase viscosity, make material that there is more preferable toughness, the presence of slaine makes the amorphous area in resin
Formation is rigidly connected, and greatly strengthen the mechanical property of covering material.Covering material hardness is made by the synergy of each component
Moderate, better softness, rebound performance is excellent, and further improves the wearability of data wire covering material, anti-flammability.
Preferably, described plasticizer is halogenation activity compound FR-V6, the just own fat of decanedioic acid two and adjacent benzene two
The mixture of formic acid dioctyl ester, its weight ratio is 3-5:2-3:1.

Thing.
Further, in the fire retardant by mass percentage：Triphenyl phosphate 10%-20%, TDE
38%-50%, antimony oxide 5-8%, balance of montmorillonite.According to aromatic series in the covering material of data wire of the present invention
Fire retardant can cause covering material in combustion in material surface Cheng Shuan, drip phenomenon is had, using meeting after montmorillonite
Drip phenomenon is substantially reduced, TDE is used alone can also produce black smoke, and adding can greatly reduce after antimony oxide
The generation of black smoke, in combustion, first low-temperature burning when, triphenyl phosphate decompose, the then decomposition of TDE,
After temperature reaches close 400 DEG C, antimony oxide, montmorillonite have started fire retardation, therefore, the fire retardant of present invention compounding
With broader temperature scope on probation, more preferable fire retardation can be played, and due to being compounded using different materials, not only
Black smoke, drip phenomenon will not be produced during fire-retardant, and with higher limited oxygen index, fire resistance is more preferably.
Further preferably, described metal chlorination salt is the mixture of lithium chloride and gallium chloride.
Further preferably, the lithium chloride and the mass ratio of gallium chloride are 1:2-3.Although lithium chloride is used alone can be increased
The toughness of strong material, but if the internal organizational structure that can destroy in matrix resin of single use lithium chloride, on the contrary can be significantly
The performance of material is reduced, and the lithium chloride and gallium chloride lithium ion and potassium ion synergy of the proportioning of present invention offer is provided,
Toughness can be strengthened, the internal structure for not destroying matrix resin is can guarantee that again, cause performance to reduce.
Preferably, described compatilizer is maleic anhydride grafted ethene-acetate ethylene copolymer (EVA-g-MAH), horse
One or two in maleic anhydride grafted ethylene-octene copolymer (POE-g-MAH).To improve between matrix resin and fire retardant
Compatibility, the present invention also need add maleic anhydride stem grafting polyolefin copolymer as compatilizer.Research shows in various nothings
In the composite that machine filler is blended with polyolefin base material, the copolymer of maleic anhydride stem grafting polyolefin is that one kind can be obviously improved
The material of compatibility between the two.
Preferably, described anti-impact modifier is one or more in MBS, CPE, ABS, EVA, ACR, NBR.Enter
Preferably, described anti-impact modifier is CPE, ACR to one step.As the loading of impact modifier increases, impact (breach) is strong
Angle value is incremented by, and CPE, ACR are linear, and overall target preferably, and has critical value, meets the multiple crazing of increasing tougheness theoretical.It is i.e. outer
Under power effect, during the resin of good combination and modifying agent two-phase (or multiphase) interface have been formed, resin produces fine crack and ripple
And rubbery state particle so as to compression, stress concentration is produced, a large amount of crazings and shear band are induced, absorb and consume and be most of
Energy；It is because that rubber particles are present again, crazing development can be controlled, prevent it from becoming destructive crackle, toughening effect becomes strong,
System impact strength is improved, more notable to improving the effect of non-notch impact strength.
Preferably, the covering material of described data wire also includes anti-wear agent 2-10 parts.Further preferably, it is described resistance to
Grinding agent is one or two in polytetrafluoroethylene (PTFE), high wear-resistant carbon black.
Preferably, the covering material of described data wire also includes 3-5 part coupling agents.
Further preferably, described coupling agent is silane coupler.Silane coupler has 2 kinds of groups of different nature,
Close inorganic matter group can react with the chemical group of mineral surfaces, form strong chemical bonding；Organophilic group can be with
Organic molecule reacts or physical entanglement, so that organic realize chemical bonding with inorganic material interface, increases substantially viscous
Connect intensity.And silane coupler is added in resin, moreover it is possible to improve compatibility, the manufacturability between inorganic filler and matrix resin
Can, improve the mechanical performance of the covering material of data wire.
Preferably, described processing aid includes heat stabilizer, light stabilizer, antioxidant, lubricant, toner.
