Problems solved by technology

[0002] Due to the insufficient mechanical strength of the rubber linings in the current market, the mud pumps used in coal, petroleum, wells, etc. are prone to surface deformation or even cracking after impact. After cracking, water seeps in and affects the function of the string protection

Abstract

The invention discloses a high-strength slurry pump rubber lining which is characterized in that the rubber raw material comprises the following components: 70-90 parts of 1# natural rubber, 30-50 parts of 21-type chloroprene rubber, 2-3 parts of stearic acid, 1-2 parts of paraffin, 22 parts of 1500-type styrene butadiene rubber, 43 parts of 3707-type nitrile butadiene rubber, 37 parts of argil, 2-5 parts of vaseline, 15-25 parts of hard carbon black, 20-30 parts of calcium carbonate, 3-5 parts of zinc oxide, 4-5 parts of magnesium oxide, 0.3-0.5 part of accelerator DM (Chinese name: 2,2'-dithiodibenzothiazole, molecular formula: C14H8N2S4), 1.1-1.3 parts of accelerator TT (Chinese name: tetramethylthiuram disulfide, molecular formula: C6H12N2S4), 0.9-1.1 parts of anti-aging agent 4010 (N-cumene-N-phenylenep-phenylenediamine) and 0.9-1 part of anti-aging agent D (Chinese name: N-phenyl-2-naphthylamine, molecular formula: C16H13N). Through the invention, the tensile breaking strength of the slurry pump rubber lining is improved by changing the proportion of the polar material and polysulfur bond of the rubber material.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a high-strength mud pump rubber lining. Background technique [0002] The mud pumps used in coal, oil, shaft and other places are prone to surface deformation or even cracking after impact due to the insufficient mechanical strength of the rubber lining in the current market.
