Description
Technical field
The present invention relates to the technical field of cable, in particular to a kind of cable jacket tears pvc material and its system with easy
Preparation Method.
Background technique
The insulating layer that cable generally includes internal core and is wrapped in outside core, wherein core is by several or several
Group conductor strand forms, for the transmission of conductive or signal, insulating layer for core to be isolated, avoid core leak electricity or signal scatter and disappear it is dry
It disturbs.As needed, the outside of insulating layer is usually also wrapped on armor, filled layer, anti-interference layer etc..The outermost layer of cable is usual
It is additionally provided with sheath, sheath plays the role of protecting internal core, insulating layer isostructural, and pvc material is to prepare sheath
Common used material.
In the actual installation process of cable, need to remove the sheath of cable, in order to the connection of route.However, mesh
The sheath removing of preceding cable is usually more difficult, on the one hand, increases the labor intensity of operator, on the other hand, is greatly reduced
The efficiency of cable mounting and installation.So being one of the important directions of line cable industry development for the exploitation for easily tearing sheath material.
It is existing to can refer to the Chinese patent application that Authorization Notice No. is CN103509283B, it is blended easily it discloses a kind of
Wire cable material is torn, is made by the raw material of following weight parts: SG-3 polyvinyl chloride 130-140, the pungent vinegar 1.2- of phthalic acid two
1.5, haloflex 6-8, calcium carbonate 10-20, polyethylene wax 3-5, cashew nut shell oil 2-4, antioxidant A W 2.4-3.8, promotor
HOBS 1-2, vulcanizing agent DCBP 1-2, (dimethylamino methyl) phenol of polyisobutene 2-4,2.4.6 mono- or three 1.2-1.5, carbon modified
Fiber 10-20, compounded mix 20-30, titanium dioxide 2-4, silica flour 4-6, triglyceride vinegar 0.4-0.8, epoxystearic acid are pungent
Vinegar 1.4-3.
How further to develop and easily tear sheath material, is still supplement cable manufacturing, abundant market, promotes cable row
One of the important measures that industry further develops.
Summary of the invention
In view of the shortcomings of the prior art, the purpose of the present invention one is: providing a kind of cable jacket with easily tearing polyvinyl chloride material
Material has and easily tears characteristic along longitudinal direction, the sheath of cable is made of this kind of material, in the actual installation process of cable, so that shield
Set is easily peeled off, and thus reduces labor intensity, improves the mounting and installation efficiency of cable.
The first purpose of this invention has the technical scheme that
A kind of cable jacket includes following components by weight with easily pvc material is torn: 90-115 parts of polyvinyl chloride resin,
45-58 parts of dioctyl terephthalate, 95-110 parts of nanometer calcium, 4.6-5.4 parts of calcium zinc stabilizer, 0.8-1.3 parts of in-lubricant,
0.5-1.2 parts of external lubricant.
By using above scheme, polyvinyl chloride resin is the main component in proportion of the invention;Dioctyl terephthalate seat
As the plasticizer in proportion of the invention, have heat-resisting, cold-resistant, difficult volatilization, anti-extraction, flexibility and electrical insulation capability good etc.
Advantage;Calcium zinc stabilizer is synthesized for main component using special combination process by calcium salt, zinc salt, lubricant, antioxidant etc., no
But the toxic stabilizer such as can replace lead cadmium salt class and organic tin, and have fairly good thermal stability, photostability and
The transparency and the features such as tinting strength, tinting power, processing performance are good, thermostabilization is good, nontoxic.
Interior lubrication can reduce the lubrication of polymer molecule interchain internal friction, good with the compatibility of polymer, can be with
It evenly spreads between strand, to reduce the interior friction of strand, improves the mobility of polymer, to improve polychlorostyrene second
The uniformity of the matrix of alkene material when tearing, can reduce being adhered between different component, to improve pvc material
Tear resistance, convenient for the installation of cable.
Compatibility between external lubricant and PVC base system is smaller, on the one hand, raw in the processing of pvc material
During production, lubricant molecular layer can be formed in interface, to reduce polymer from the interior shifting of polymer to surface
Being adhered between production equipment body;On the other hand, when producing cable jacket using pvc material of the invention, outside
Lubricant can be transferred to the inner surface and the outer surface of sheath, to further increase the tearability of sheath.
In pvc material provided by the invention, filler using nanometer calcium as pvc material, and substantially mention
The addition of weight percent of the high nanometer calcium in pvc material, nanometer calcium can cooperate with other components, and effectively mention
The tearability energy of high pvc material of the invention.
Said components proportion of the invention is succinct, can work in coordination between each component.With preferable synergy.It is real
Number is tested it was demonstrated that the cable jacket of said ratio has with easily pvc material is torn and easily tears characteristic along longitudinal direction, by this kind of material
The sheath of cable is made, in the actual installation process of cable, so that sheath is easily peeled off, thus reduces labor intensity, improves
The mounting and installation efficiency of cable.

Comparative example 1
Common commercially available sheath pvc material.
Performance detection
For the pvc material to embodiment 1-6 and the preparation of comparative example 1: according to the regulation of GB2951.11-2008, carrying out
Senile experiment, experiment condition are as follows: experiment condition is 100 DEG C × 168h;Tearing detection longitudinal tear difficulty manually, grade of difficulty point
For 1-10, rank is higher, is more difficult to tear;Above-mentioned testing result is as shown in table 1.
1 performance test results of table
According to table 1 as can be seen that compared to comparative example 1, the pvc material of embodiment 1-6 preparation is more easily torn along longitudinal direction
It splits, that is, has and easily tear characteristic along longitudinal direction, the sheath of cable is made of pvc material of the invention, in the actual installation of cable
In the process, so that sheath is easily peeled off, labor intensity is thus reduced, improves the mounting and installation efficiency of cable.
Furthermore embodiment 1-6 preparation pvc material by 100 DEG C × 168h aging after, tensile strength and break
It splits elongation and changes unobvious, and the stretching of the common commercially available sheath pvc material in comparative example 1 compared with before aging
There is decline by a relatively large margin in intensity and elongation at break.It is good that this illustrates that pvc material prepared by the present invention has
The characteristic of heat resistant is particularly suitable for the higher installation site of use environment temperature.
The addition that comparative example 2,4-6 can be seen that carbon fiber, silicone grease and glass fibre can be obviously improved polychlorostyrene second
The heat resistant performance of alkene material, meanwhile, the influence to the longitudinal tear difficulty of pvc material is little.
