Abstract

The invention discloses a piston rubber material for mud pumps. The piston rubber material is made from the following raw materials in parts by weight: 20-30 parts of fluorosilicone rubber, 50-60 parts of hydrogenated nitrile rubber, 15-25 parts of chlorosulfonated polyethylene rubber TS-320 (Tosoh), 2-3 parts of gamma-methacryloxypropyl trimethoxy silane, 1-2 parts of diphenyl silanediol, 14-16 parts of modified tree ashes, 2-3 parts of ferrocene, 0.2-0.6 part of dicumyl peroxide (DCP), 20-30 parts of high abrasion furnace (HAF) black N330, 20-25 parts of precipitated silica, 5-7 parts of light calcium carbonate, 2-4 parts of zinc oxide, 1-3 parts of calcium stearate, 1-3 parts of aluminum oxide, 5-8 parts of dolomite, 13-15 parts of modified iron ore tailing powder, 0.1-0.3 part of accelerant MBTS, 1-2 parts of sulfur, 1-2 parts of anti-aging agent RD, 1-2 parts of anti-aging agent MB, 1-2 parts of 2-mercaptobenzimidazole, 1-3 parts of methyl trimethoxysilane and 2-3 parts of paraffin wax. The rubber material disclosed by the invention has excellent resistance to high/low temperature, oil, solvents and chemicals; and meanwhile, the mechanical property is good, and the cost is low.

Description

technical field [0001] The invention relates to the field of synthetic rubber, in particular to a piston rubber for a mud pump and a preparation method thereof. Background technique [0002] Fluorosilicone rubber has excellent high and low temperature resistance, oil resistance, solvent resistance and chemical resistance. A new type of low temperature sealing material and fuel oil hose. [0003] In the prior art, a basic fluorosilicone raw rubber is used to prepare fluorosilicone compounded rubber through mixing. Due to the different molecular weight distribution and average molecular weight of different fluorosilicone raw rubber, the properties of fluorosilicone rubber compounded by mixing a single raw rubber are different. The high molecular weight of raw rubber has good tensile strength and tear strength. Good oil resistance, but poor processability and difficult mixing. The low molecular weight of raw rubber makes it difficult to have good tensile strength and tear st...
