The mass ratio of compound and gelatin is 1:2-6.By the way that the mixture of gelatin and rare earth oxide is added, PVC electricity can significantly improve
The cold tolerance of cable material, and shape simply, it is conducive to production.Using the reapective features of rare earth oxide, PVC and gelatin by rare earth
Oxide and gelatin doping are bonded in PVC, by the synergistic effect of three be obviously improved the mechanical property of PVC cable material with
Processing performance especially improves its cold tolerance, and the temperature that resists cold is up to subzero 52 degree.
Rare earth oxide is preferably the mixture of lanthana and yttrium oxide, mass ratio 1:1.5-2.5, relative to other dilute
The mixture of native oxide, lanthana and yttrium oxide can more cooperate the cold tolerance for significantly improving PVC with gelatin, and guarantee
The toughness and shock resistance of PVC cable at low temperature.
The PVC cable material is also further added with polyimides, the matter of the rare earth oxide, gelatin and polyimides
Measure ratio are as follows: 1:2-6:0.5, the addition of polyimides can be improved cold resistance, heat resistance, wearability, the tensile strength of PVC cable
Etc. comprehensive performances.
The mixture of rare earth oxide and gelatin of the invention can be individually added into PVC cable material, can also be with other auxiliary agents
(one of plasticizer, stabilizer, lubricant, filler, antioxidant or a variety of), which merge, to be used.It is exemplified below, PVC cable material
Parts by weight composition are as follows: PVC 100；Rare earth oxide 10-15；Gelatin 20-90；Polyimides 5-7.5；Plasticizer 30-50；Surely
Determine agent 5-9；Lubricant 1-2.
Further, the plasticizer is preferably adipic acid ester plasticizer, sebacic acid ester plasticizer, A.G.S. acid esters
Or mixtures thereof any type in class plasticizer.
Further, the stabilizer is preferably calcium-zinc composite stabilizing agent.
Further, the lubricant is preferably stearic acid and its esters, stearates, polyethylene wax, the poly- second of oxidation
Alkene wax, paraffin, stearic amide, any one or more than one in oleamide mixture.
The present invention also provides a kind of preparation methods of modified PVC CABLE MATERIALS, by weight, in 100 parts of PVC, successively add
Add 10-15 parts of rare earth oxide, 10-30 parts of gelatin, 5-7.5 parts of polyimides, 30-50 parts of plasticizer, 5-9 parts of stabilizer, profit
, temperature is controlled between 80 DEG C~100 DEG C, is mediated 10-30 minutes, then put into cold blender 1-10 points of stirring by 1-2 parts of lubrication prescription
Clock discharging will be mediated material and is put into extruding machine, and temperature control is granulated between 120 DEG C -150 DEG C to get cold-resistant modified PVC cable
Material.
Compared with the prior art, the present invention has the following beneficial effects:
(1) rare earth oxide and gelatin are adulterated or is bonded to using the reapective features of rare earth oxide, PVC and gelatin
In PVC, it is obviously improved the mechanical property and processing performance of PVC cable material by the synergistic effect of three, it is cold-resistant especially to improve it
Performance, the temperature that resists cold is up to subzero 52 degree；
(2) due to the macromolecular structure characteristic of rare earth oxide, gelatin, polyimides and PVC, rare earth oxide, gelatin
It can adulterate or be bonded in PVC with polyimides, be fused to each other and be easier to, therefore, simple production process is easily formed, at
This is low.
