Rubber-sheathed cable environment friendly antibacterial sheath composition for radio device

Abstract

The invention provides a rubber-sheathed cable environment friendly antibacterial sheath composition for a radio device. The composition comprises the following parts of components by weight: 766 parts of natural rubber, 679 parts of butadiene styrene rubber, 18 parts of accelerator TMTD, 1 part of accelerator ZDC, 33 parts of anti-aging agent RD, 11 parts of anti-aging agent 4010 NA, 56 parts of nano zinc oxide, 89 parts of stearic acid, 54 parts of paraffin wax, 567 parts of argil, 694 parts of calcium carbonate, 278 parts of mixed gas carbon black, 69 parts of engine oil 32#, 289 parts of nano white carbon and 7 parts of rubber mould inhibitor; according to the invention, a prepared product is free of lead, mercury and so on; ROHS requirements are satisfied; through the adoption of the anti-aging agents RD and 4010 NA, ozone resistance of the product is additionally provided and cracks are prevented on a sheath for a cable; through the adoption of the nano zinc oxide, a product has the advantages of extremely strong wear resistance, tear resistance, heat resistance and other mechanical properties; as a softening agent is added, low temperature performance is improved; and as an additive RHA-M-1 is added, an extremely strong antibacterial effect is obtained.

Description

technical field [0001] The invention relates to an environment-friendly and antibacterial sheath composition for rubber cables used in radio devices. Background technique [0002] Cable sheaths are widely used in communication equipment, instruments, and power distribution equipment on vehicles. Due to the influence of environmental factors and working conditions, cable sheaths are required to have basic properties such as insulation. In order to adapt to different applications, they also require The cable sheath has excellent properties in terms of tensile performance, hardness, anti-aging, elasticity, antibacterial, and flex aging protection. However, with the development of science and technology, the cable sheath can no longer meet the needs of related equipment, especially for aerospace, etc. Under extreme environmental conditions, the cable sheath prepared by the current cable sheath formula is difficult to adapt to such working environment, especially the existing cab...

[0002] Cable sheaths are widely used in communication equipment, instruments, and power distribution equipment on vehicles. Due to the influence of environmental factors and working conditions, cable sheaths are required to have basic properties such as insulation. In order to adapt to different applications, they also require The cable sheath has excellent properties in terms of tensile performance, hardness, anti-aging, elasticity, antibacterial, and flex aging protection. However, with the development of science and technology, the cable sheath can no longer meet the needs of related equipment, especially for aerospace, etc. Under extreme environmental conditions, the cable sheath prepared by the current cable sheath formula has been difficult to adapt to such working environment, especially the existing cable sheath does not have the performance of ozone oxidation resistance

Moreover, the production of traditional cable sheaths involves the production process of rubber. The traditional rubber vulcanization process is complex, and the products contain a large amount of toxic compounds such as sulfur, mercury or lead that may cause serious environmental pollution, especially long-term contact with rubber products with high sulfur content. , not only endangers human health, but also produces a large amount of sulfur-containing gas in the desulfurization process after scrapping, polluting the environment, so reducing the content of harmful substances in rubber products is conducive to protecting the environment
