Abstract

The invention discloses a styrene butadiene rubber used for preparing material delivery hoses. The styrene butadiene rubber is prepared from, by weight, 100 to 130 parts of SBR, 100 to 110 parts of butadiene rubber, 50 to 55 parts of hydrogenated nitrile butadiene rubber, 4 to 5 parts of phenyltriethoxysilane, 3 to 5 parts of a filler, 5 to 7 parts of sodium citrate, 5 to 8 parts of tris(2,4-di-tert-butylphenyl) phosphate, 2 to 4 parts of silicon carbide whisker, 6 to 8 parts of polyethyleneglycol monooleate, 6 to 9 parts of m-xylylenediamine, 13 to 16 parts of an abrasion resistance improver, 15 to 26 parts of poly-n-butyl methacrylate, 2 to 5 parts of a plasticizer, and 30 to 40 parts of glycerinum. The styrene butadiene rubber is excellent in physical and mechanical properties, is capable of increasing product tensile strength and stress at definite elongation, and reducing compression deformation and dynamic heat build-up performance.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and in particular relates to a styrene-butadiene rubber used for preparing a material suction hose. [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 perform...
