D. obtained premix being put into open mill, sulphur is then added and is mixed, processing temperature is 68-80 DEG C,
It is logical 2-3 times thin, then in turn through extrusion and compression molding, you can.
By being modified to filler, it is then added in chemical pumping rubber packing material of the present invention, to sealing material
The improvement of tearing-resistant performance and ageing-resistant performance is more prominent, compared to the tensile strength of general chemistry pump sealing material
60.2% is improved, tearing strength improves 45.6%, and rubber packing material dimensional stability is greatly improved, while also pole
The big oil resistivity, corrosion resistance and air-tightness for improving rubber packing material, this is adopted in prepared by previous rubber packing material
The effect that common fillers are unable to reach greatly improves the quality of chemical pumping rubber packing material of the present invention and makes
With the service life, the service life compared to general chemistry pump rubber packing material improves 2-3 times.
The beneficial effects of the invention are as follows：Compared with prior art, the chemical pumping that prepared by the present invention has with rubber packing material
Have the advantages that flexibility, low-density, compression resilience and use temperature range are wide, economic well-being of workers and staff at low cost is high, has higher
Tensile strength, tearing strength and wearability, elasticity modulus is big, high temperature resistant, resistant to chemical etching, good heat conductivity, coefficient of thermal expansion
Low advantage, and there is self lubricity；Each ingredient is uniformly dispersed in sealing material, and stability is high, close to further increase
The thermal diffusivity of sealing material can be greatly improved by the synergistic effect between each ingredient and modified filler in the performance of closure material,
The phenomenon that not will produce temperature accumulation, chemical pumping of the present invention also can effectively prevent bacterium with rubber packing material leads to rubber material
It is mouldy, corrode and change colour to obtain phenomenon occur.
