Heatproof rubber

Abstract

The invention discloses heatproof rubber. The heatproof rubber is prepared from, by weight, 80-120 parts of butyl rubber, 1-2 parts of sulfur, 0.3-0.5 part of an accelerant M, 0.8-1.2 parts of an accelerant TT, 3-5 parts of zinc oxide, 3-5 parts of magnesium oxide, 0.8-1.2 parts of stearic acid, 2-4 parts of paraffin, 1-1.3 parts of a heat aging inhibitor D, 50-80 parts of aluminum silicate, 40-60 parts of calcium carbonate and 1-3 parts of a p-phenylenediamine anti-aging agent. The heatproof rubber has advantages that by proportional addition of the heat aging inhibitor in the formulation, thermal oxygen free atom absorbability of the rubber at a high temperature is improved, reaction caused by contact of thermal oxygen free atoms and a rubber main chain is avoided, heat resistance of the heatproof rubber is remarkably improved as compared with that of existing rubber, and service lives of rubber products are prolonged.

Description

technical field [0001] The invention relates to a rubber material, in particular to a heat-resistant rubber. Background technique [0002] At present, rubber tubes are widely used in various fields, but the heat resistance of rubber tubes on the existing market is generally not good. It is easy to cause premature aging, cracking and stickiness on the surface when used at high temperatures, and the surface will appear for a long time. If it falls off, it loses its function, and the heat-resistant rubber tube is discarded. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heat-resistant rubber with good heat-resistant performance. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a heat-resistant rubber, the innovation of which is: the use of the following raw materials by weight: butyl rubber: 80-120 parts; sulfur 1-2 parts; accelerator M 0.3-0.5 parts; ...
