Abstract

The invention provides a cold resistant rubber part for a pneumatic hydraulic system. The rubber raw material of the cold resistant rubber part comprises the following components in parts by weight: 100-140 parts of No.1 natural rubber, 20-40 parts of 9000 type butadiene rubber, 0.5-0.7 part of sulphur, 20-30 parts of zinc oxide, 2-3 parts of antiager NBC (the Chinese name is N,N-dibutyl dithiocarbamate nickelous formate), 30-50 parts of FEF330 carbon black (the Chinese name is fast extruding furnace black), 1.5-2 parts of stearic acid, 1.5-2 parts of paraffin, 10-12 parts of channel black, 70-90 parts of calcium carbonate, 1.5-2 parts of vaseline, 1-1.2 parts of accelerant TT (the Chinese name is tetramethyl thiuram disulfide, and the molecular formula is C6H12N2S4 ), and 1.5-2 parts of antiager D (the Chinese name is N-phenyl-2-naphthylamine, and the molecular formula is C16H13N). As non-polar rubber is adopted in a rubber formula and the usage amount of a plasticizer is increased, the free movement ability of a macromolecular chain is increased, thus the cold brittleness of the rubber is reduced.

Description

technical field [0001] The invention relates to the field of rubber, in particular to low-temperature-resistant rubber parts for pneumatic hydraulic systems. Background technique [0002] When the outdoor operating temperature of the pneumatic hydraulic system is lower than -20°C in winter, the working efficiency will drop because the rubber parts are hardened and the speed rises slowly after the power is turned on. Contents of the invention [0003] The object of the present invention is to provide a low-temperature-resistant rubber part for a pneumatic hydraulic system, which can reduce the low-temperature brittleness of rubber and improve the flexibility at low temperature. [0004] The technical solution of the present invention is to provide a low-temperature-resistant rubber part for a pneumatic hydraulic system, which is characterized in that its rubber raw material components and weight ratio are selected to be 1 # 100-140 parts of natural rubber, 20-40 parts of 9...
