Oil-resistant and aging-resistant natural rubber composite material for instrument cable

Abstract

The invention discloses an oil-resistant and aging-resistant natural rubber composite material for an instrument cable. The oil-resistant and aging-resistant natural rubber composite material comprises the following raw materials by weight: 55 to 80 parts of natural rubber, 20 to 45 parts of nitrile rubber, 2 to 3.5 parts of stearic acid, 1 to 3 parts of zinc oxide, 1.5 to 3 parts of sulfur, 1 to3.2 parts of calcium carbonate whiskers, 5 to 17 parts of carbon black, 3 to 8 parts of calcined kaolin, 5 to 9.8 parts of lead tungstate, 2 to 5 parts of a samarium compound, 0.1 to 0.3 part of an accelerator and 0.8 to 1.8 parts of an anti-aging agent. The oil-resistant and aging-resistant natural rubber composite material for the instrument cable provided by the invention has the advantages ofhigh strength, good oil resistance and excellent aging resistance.

AI Technical Summary

Benefits of technology

This patented new type of elastomeric composition called CBR (Curable Rubber Composite) uses both synthetic rubbers like NR or PE resin together with special chemical agents such as ammonium salts and alkoxides. These compositions have improved properties compared to existing materials due to their combined use of different types of components. They also maintain better stability over long periods under severe conditions without losing its original quality. Overall these technical improvements make them suitable for various applications where high durability against ozone damage and UV light exposure needs.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the performance of cable made from synthetic material that has good oxygen barrier properties when exposed to air at high temperatures over time without losing its effectiveness due to ageing issues such as degradation caused by exposure to various substances like water vapor present within an enclosed space containing electronic equipment (such as sensors) inside it's housing).
