It is interior；
2) start banbury banburying 4-5 minutes, add dispersant, age resistor and vulcanizing agent；
3) continue to start banbury banburying, banbury displays temperature is checked, when temperature to be shown reaches 95-100 degrees Celsius
Stop banburying, take out semi-finished product and radiating of making thinner；
4) semi-finished product are taken out and are divided into several pieces, on a mill it is thin it is logical after add the accelerator of respective component, turn over
Uniform aftershaping slice is refined, now temperature is no more than 90 degrees Celsius.
The metal ring framework is class T-shape metal ring framework, and the vertical portion of the class T-shape metal ring framework is dress
With internal diameter.
The modification rubber layer containing Ferrite Material is wrapped on metal ring framework in a ring.
PVC/NBR=30/70 in the PVC/NBR rubber-plastics materials.
The pvc material has high weatherability.
The beneficial effects of the invention are as follows：
1) present invention by dispersant ferromagnetic oxide powder is uniformly dispersed in rubber layer, it is ensured that transmission signal it is steady
Qualitative and uniformity
2) present invention improves the weatherability of rubber layer by adding weather resistant materials, improves life of product and reliability；
3) PVC/NBR rubber-plastics materials of the invention have advantages below：
1. the oil resistivity and cross linkable of resistance to ozone and rubber are significantly improved；
2. improve and draw high intensity, stress at definite elongation, tear resistance, heat resistance and flame resistance；
3. the performances such as oil resistant, resistance to fuel oil and chemical-resistant resistance are improved；
