Abstract

The invention relates to the technical field of damping, in particular to a high-temperature-resistant paraffin oil rubber damping cushion and a manufacturing method thereof. The high-temperature-resistant paraffin oil rubber damping cushion comprises the following components in parts by weight: 100 parts of HNBR (Hydrogenated Nitrile Butadiene Rubber) of which the hydrogenation degree is 99 percent, 5-7 parts of zinc oxide, 1-2 parts of stearic acid, 1.5-2.5 parts of an anti-aging agent 4020, 1.5-2.5 parts of an anti-aging agent RD, 25-35 parts of carbon black N660, 25-35 parts of carbon black N774, 8-12 parts of DCP (Dibasic Calcium Phosphate) and 5-7 parts of TAIC (Triallyl isocyanurate). HNBR is taken as a substrate material, general carbon black of which the particle diameter is large relatively and semi-reinforcing carbon black are taken as fillers, a peroxide, i.e., DCP and an assistant crosslinker, i.e., TAIC are adopted in a vulcanization system, so that the problems of poor compressive permanent deformation property and poor high temperature resistance existing in the conventional material can be solved by using the damping cushion, and the requirements of practical conditions are met.

Description

technical field [0001] The invention relates to the technical field of shock absorption, in particular to a high temperature resistant paraffin oil rubber shock absorber and a manufacturing method thereof. Background technique [0002] Most of the current shock absorbing pads are only suitable for ordinary working conditions, and their compression set performance is poor, and their high temperature resistance is poor, so it is difficult to apply to special working conditions. A high-temperature-resistant paraffin oil rubber shock absorber and a manufacturing method thereof are provided to meet the needs of actual conditions. Contents of the invention [0003] The object of the present invention is to propose a kind of high temperature resistant paraffin oil rubber shock absorber and manufacture method thereof, it selects hydrogenated nitrile butadiene rubber as matrix material, and selects general-purpose and semi-reinforcing carbon black with relatively large particle siz...
