Abstract

The present invention discloses a linear rubber material of a linear rubber butterfly, which is obtained through compounding rubber mass A and rubber mass B. The rubber mass A and rubber mass B are respectively composed of the following components in weight percentage: the rubber mass A is composed of: 85-95 part of nitrile butadine rubber, 0.3-0.5 part of sulphur, 4-6 parts of zinc oxide, 3-4 parts of eleaostearic acid, 2 parts of antioxidant, 1-2 parts of 5-di-tert-butylhydroquinone DTBHQ, 1-2 parts of antioxidant RD, 1-2 parts of antioxidant OD, 3-4 parts of paraffin, 22-25 parts of fast extruding furnace black N660, 62-65 parts of high-wearing-resistance furnace carbon N330, 18-22 parts of dioctyl, 25-35 parts of attapulgite, 3-4 parts of promoter M, 1-2 parts of promoter DM, and 1-2 parts of promoter PZ; and the rubber mass B is composed of: 85-95 parts of fluorubber 246, 1-2 parts of zinc stearate, 1-3 parts of antioxidant RD, 0.4-0.6 part of furnace black dispersing agent T-78,1-2 parts of antilux, 45-55 parts of fast extruding furnace black, 10-14 parts of pottery clay, 5-8 parts of dioctyl, 4-6 parts of lead tetraoxide, 0.8 part of vulcanizing agent DTDM, and 1-2 parts of promoter CZ. The linear rubber material of the invention has excellent comprehensive performance. The vulcanized liner rubber butterfly valve has the following characteristics: good air-tightness, high weather resistance, high low-temperature resistance, high oil resistance, low material cost, etc.

Description

technical field [0001] The invention relates to the field of rubber composite material processing, in particular to a rubber-lined rubber material for a rubber-lined butterfly valve and a preparation method thereof. Background technique [0002] In the fluid pipeline system, the valve is the control element, its main function is to isolate the equipment and the pipeline system, adjust the flow, prevent backflow, adjust and discharge the pressure, so the requirements for the sealing and corrosion resistance of the valve are relatively high. The existing casting The high temperature resistance and corrosion resistance of butterfly valves are not very good. Then, rubber-lined butterfly valves are more and more widely used. The high temperature resistance and corrosion resistance of the rubber-lined rubber materials of existing rubber-lined butterfly valves are not very ideal. Although some have good corrosion resistance, the raw materials are expensive and the cost is high. C...
