Abstract

The invention relates to low water absorption rate rubber for a rubber pipe for conveying food oil. The rubber comprises the following components in parts by weight: 70-100 parts of 1#natural rubber, 30-50 parts of 9000 type butadiene rubber, 1-2 parts of sulphur, 3-5 parts of zinc oxide, 2-3 parts of anti-aging agent DTPD (domestic name: anti-aging agent 3100, Chinese name: N,N'-bis(methylphenyl)-p-phenylenediamine mixture), 2-4 parts of stearic acid, 2-3 parts of paraffin, 3-5 parts of vaseline, 70-90 parts of spraying carbon black, 50-80 parts of 600-mu calcium oxide and 1-2 parts of accelerant CZ with a molecular formula of C13H16N2S2 and a chemical name of N-cyclohexy1-2-benzothiazole sulfonamide. Water permeating through the rubber is absorbed through adding a modifying material, and therefore, the ageing of the main body material, caused by hydrolysis discoloring due to water absorption, is avoided.
