Abstract

An assemblage used for manufacturing the low-hardness rubber materials is characterized in that the ethylene propylene diene monomer and the polynorbornene rubber are both used in a mass ratio ranging from 25 to 35 / 75 to 65, with the cycloalkane oil as the softner and the DTDM as the curing agent. The third monomer of the ethylene propylene diene monomer is the ethylidene norbornene (ENB) and the suitable content of the propylene ranges from 20 per cent to 30 per cent in mass percentage.

Description

technical field

[0001] The present invention relates to the rubber processing industry in the field of chemical industry, in particular to a compounding technology of a rubber composition, that is, to provide a composition for manufacturing low-hardness and high-damping rubber materials. Background technique

[0002] With the rapid development of science and technology today, many equipment and instruments are equipped with high-sensitivity and high-precision instruments and meters, which are of great significance for controlling the correct operation of equipment and maintaining normal production. However, as the equipment runs faster and faster, vibration will inevitably occur. For this type of precision instrument, even a slight high-frequency vibration will cause deviations in the accuracy of the instrument and even affect its normal use. This can have adverse consequences for scientific experimental data and production process control. The most effective way to elimina...
