Abstract

The invention discloses NBR rubber for welding hoses, which is prepared from, by weight, 150-195 parts of NBR, 10-20 parts of methyl acrylate, 50-55 parts of hydrogenated nitrile butadiene rubber, 10-20 parts of phenylene silicone rubber, 6-9 parts of phthalic dimethyl anhydride, 6-14 parts of coconut oil monoethanolamide, 3-7 parts of butylbenzyl phthalate, 12-14 parts of silicon carbide crystal whiskers, 5-10 parts of epoxy soybean oil, 4-8 parts of a filling agent, 6-9 parts of m-xylylenediamine, 4-8 parts of a silane coupling agent, 1-6 parts of an anti-coking agent, and 3-5 parts of stannous octoate. The NBR rubber for welding hoses is both rigid and flexible, not only has enough mechanical performances but also has excellent flexibility, and has good low temperature resistance and ozone tolerance.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to NBR rubber for welding hoses. [0002] technical background [0003] Rubber hose refers to a steel wire braided hose, which generally consists of an inner rubber layer, a steel wire braided layer and an outer rubber layer. Suitable for conveying hydraulic fluids, such as alcohol, fuel oil, lubricating oil, emulsion and so on. The biggest feature of (rubber) hoses that distinguishes them from rigid pipes is their bendability. Compared with civil (rubber) hoses, the industrial operating environment is more complex and harsh, and the equipment has more stringent requirements for delivery pipes. Therefore, industrial (rubber) hoses are designed from design, material selection to production, transportation and even final storage. There are strict norms and standards. According to the different working conditions and performance requirements, the design of hoses varies gr...
