Abstract

The invention relates to the technical field of rubber, in particular to a high-temperature-resistant high-fatigue-resistance natural rubber preparation raw material. The rubber is prepared from, by mass, 100 parts of smoke sheet rubber, 3-8 parts of zinc oxide, 1-2 parts of stearic acid, 1-3 parts of anti-aging agent RD, 1-2 parts of anti-aging agent 4010NA, 1-2 parts of anti-aging agent 4020, 2-5 parts of microcrystalline wax 9332F, 3-5 parts of silane coupling agent Si-669 / G, 0.5-1.5 parts of PAPI, 20-40 parts of carbon black N330, 30-60 parts of carbon blackN660, 10-30 parts of barium sulfate, 5-20 parts of aromatic oil Tudalen 84, 2-3 parts of sulphur, 1-2 parts of accelerant CZ, 0.5-1 parts of IDH, and 2-4 parts of Perkalink 900. By reasonably adjusting a formula system, the fatiguelife, the temperature resistance and the vulcanization reversion resistance of the natural rubber can be remarkably improved.

Description

technical field

[0001] The invention relates to the technical field of rubber, in particular to a raw material for preparing natural rubber with high temperature resistance and high fatigue resistance. Background technique

[0002] In the process of continuous development of the rubber industry, rubber products are more and more widely used in aerospace, automobile, industrial products and other fields, but the requirements for rubber are becoming more and more stringent. Most of the automotive vibration damping products use natural rubber. In order to improve the technical performance of natural rubber such as aging resistance, wear resistance, and fatigue life, most of them use BR (butadiene rubber) and SBR (styrene-butadiene rubber) together. With the continuous development, some companies will also use TPI (trans-polyisoprene rubber), TBIR (trans-butadiene rubber), etc., but at the same time, they will lose some of the unique properties of natural rubber. BR rubber will...
