Parts by weight into raw material are：CPE/EPDM 95-105, ethylene-vinyl acetate copolymer 25-35, poly- 4-methyl-1-pentene 20-
30th, the double stearoylketene amine 25-30 of calcium stearate 12-15, semi-reinforcing hydrocarbon black 70-90, ethylene group, vinegar 3-8, N in poly- caproic acid, N '-
Penylene BMI 5-8, age resistor TPPD 2-3, cumyl peroxide 2-3 and Firebrake ZB 4-6.The invention solves
PVC insulated power cable is local at subzero 40 DEG C, and cable embrittlement can not be installed and frequent torsion problem；In addition, improve
Cable pliability, in the case where keeping cable that there is preferable pliability, improve the intensity of cable.But, the sheath
Brittle temperature be subzero 40 DEG C, its properties declines to a great extent in the environment of less than this temperature, and resistance to low temperature is not good enough.
The content of the invention：
The technical problem to be solved in the present invention is to provide a kind of low temperature resistant EPDM CABLE MATERIALSs, its resistance to low temperature are fine.
In order to solve the above technical problems, the technical scheme is that：

70~90 parts of filler, 0.1~0.2 part of coupling agent, 1~2 part of age resistor, the crosslinking agent are peroxy ketal.
Preferably, compatilizer of the present invention is EPDM-g-MAH.
Preferably, vulcanizing agent of the present invention is DTDM.
Preferably, co-curing agent of the present invention is TAIC.
Preferably, filler of the present invention is at least one of talcum powder, calcined kaolin.
Preferably, coupling agent of the present invention is KH550.
Preferably, age resistor of the present invention is antioxidant MB.
Another technical problem to be solved by the present invention is that provide the preparation method of above-mentioned low temperature resistant EPDM CABLE MATERIALSs.
In order to solve the above technical problems, technical scheme is：
The preparation method of low temperature resistant EPDM CABLE MATERIALSs, its step are as follows：
(1) EPDM, MAH, DCP are added into high-speed kneading machine to mix 10 minutes, moves to double screw extruder melting extrusion, it is double
Each section of temperature of screw extruder is respectively 150 DEG C, 160 DEG C, 170 DEG C, and head temperature is 170 DEG C, and the pellet of extrusion is dried
After be dissolved in dimethylbenzene, flowed back 2 hours at 60 DEG C, cooled and filtered, filter cake is placed in vacuum drying chamber after washing 3 times with ethanol
Dried 3 hours at 90 DEG C, obtain compatilizer；
(2) compatilizer and other components in addition to vulcanizing agent, co-curing agent obtained step (1) by formula adds
Enter and obtain elastomeric compound after being kneaded 12 minutes at 100 DEG C of banbury, deposited after elastomeric compound is placed in mill into thin logical 2 times, pendulum glue 2 times
Put 9 hours, add at 110 DEG C of banbury and be kneaded 1 minute together with vulcanizing agent, co-curing agent, move to the thin logical 2 times, pendulum of mill
Glue 3 times, is cooled down after rolling out film with chill roll, obtains low temperature resistant EPDM CABLE MATERIALSs.
Therefore compared with prior art, the invention has the advantages that：
1) EVA is ethane-acetic acid ethyenyl (vinyl acetate) ester copolymer, has good resistance to low temperature, its brittle temperature
As little as -70 DEG C of degree, but its compatibility between EPDM is not ideal, therefore the present invention utilizes maleic anhydride MAH in EPDM
On carried out fusion-grafting compatilizer EPDM-g-MAH be made, the compatibility between MAH and EVA is preferable, and the compatilizer can have
Effect improves the compatibility between EPDM, EVA, strengthens adhesion between the two, homogeneous blending is formed, so as to reduce CABLE MATERIALS
Brittle temperature, improve its resistance to low temperature.
2) ECO rubber is the epichlorohydrin rubber formed by epoxychloropropane and oxirane copolymerization, has good cold resistance,
Contain the preferable ehter bond of compliance in its structure, ECO rubber can introduce ehter bond after adding EPDM on EPDM strands, effectively carry
The high compliance of strand, so as to reduce its brittle temperature, but the compatibility between ECO rubber and EPDM is bad, therefore
The present invention also added MMA and crosslinking agent, and in blending, MMA can occur graft copolymerization with EPDM and form graft copolymer
EPDM-g-MMA and PMMA, and ECO rubber can be fully compatible with PMMA, so just forms the extraordinary mixture of compatibility
System, so as to further improve the resistance to low temperature of CABLE MATERIALS.
