Abstract

The invention discloses an inner rubber material used for a water delivery hose. The inner rubber material is prepared from raw materials including, by weight, 140-150 parts of PVC, 80-85 parts of fluorinated silicone rubber, 20-30 parts of poly (butylenes terephthalate), 5-14 parts of an antioxidant, 4-8 parts of aluminum oxide, 3-5 parts of triphenyl phosphate, 13-15 parts of acrylic resin, 8-12 parts of thiocarbanilide, 12-17 parts of a reactive diluent, 30-40 parts of glass fiber, 5-9 parts of phthalic anhydride, 3-8 parts of a benzenesulfonic acid type catalyst, 1-5 parts of methyltin mercaptide and 1-4 parts of an aluminate coupling agent. The inner rubber material used for the water delivery hose is good in flexibility, resistant to distortion, good in bending performance, capable of bearing heavy loads and resistant to flex cracking.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an inner rubber material for a water delivery 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 performance requirements, the des...
