Problems solved by technology

[0002] The rubber track is composed of rubber body, transmission parts, steel cord and canvas (or nylon), etc. It has the characteristics of high adhesion, low operating noise, small vibration, small damage to the soil layer and low ground pressure. It is widely used in combine harvesters, and the normal service life of rubber tracks is about 1000h (hours). However, most of the current rubber tracks have the problem of being difficult to maintain excellent performance and appearance in a relatively harsh environment. For this reason, a The rubber track that can solve the above problems, in order to meet the needs of the actual situation

Abstract

The invention belongs to the technical field of rubber tracks and preparation thereof, specifically relating to a high-strength rubber track for excavating machines and a manufacturing method thereof. The high-strength rubber track contains the following raw materials by weight part: 100 parts of natural rubber, 3-6 parts of zinc oxide, 1.5-2.5 parts of stearic acid, 1-2 parts of an anti-aging agent 4010 NA, 1-2 parts of an anti-aging agent RD, 40-60 parts of carbon black N330, 8-12 parts of white carbon black, 2-6 parts of Si-69, 3-6 parts of aromatic oil, 2-2.8 parts of S, 1.2-1.8 parts of accelerant Cz 1.2-1.8, and 0.5-0.8 part of scorch retarder Pvi. The high-strength rubber track prolongs service life thereof, and has the advantages of excellent appearance, low hardness, high tear resistance, high tensile strength, excellent ageing resistance and ozone resistance. The high-strength rubber track has lower dynamic heating performance, so the high-strength rubber track can keep excellent performance and appearance under the more bad service environment; the technology is simple; and raw material ratio is reasonable.
