Rubber composition for track of snow pressing vehicle and preparation method of rubber composition

Abstract

The invention relates to a rubber composition for a track of a snow pressing vehicle and a preparation method of the rubber composition. The rubber composition comprises the following components in parts by weight: 100 parts of natural rubber, butadiene styrene rubber and butadiene rubber; 2-10 parts of a functional auxiliary agent; 40 to 80 parts of a reinforcing agent; 2-6.5 parts of an anti-aging agent; 2-5 parts of a vulcanizing agent; 0.7 to 3 parts of an accelerant; 1-7 parts of zinc oxide; 0.5 to 5 parts of stearic acid; 0.1 to 1 part of scorch retarder; 0.5 to 3 parts of a silane coupling agent; 1-20 parts of a plasticizer; the functional auxiliary agent is obtained by grafting a functional small molecule compound into a molecular chain of natural rubber by taking natural rubber as a raw material and through a click chemical reaction, the functional small molecule compound is 1, 2, 4-triazoline-3, 5-diketone (TAD) and a derivative thereof, the tear resistance, cold resistance, fatigue resistance, cutting resistance and the like of the rubber composition are greatly enhanced.

Description

technical field [0001] The present invention generally relates to the technical field of chemical engineering, and more specifically relates to a rubber composition used for snow groomer tracks and a preparation method thereof. Background technique [0002] The snow groomer is used for pushing snow, leveling snow, laying snow, compacting snow and breaking hard snow, etc. Since the snow groomer works in the snow and the temperature is low, the low temperature resistance of the materials of the snow groomer components The requirements are relatively high. The walking part of the snow groomer is composed of a frame, a track, a suspension system, a roller, and a motor. The track is composed of a rubber composition and metal parts. The rubber composition not only has shock absorption, noise reduction, etc. It also has good physical properties and light weight, which can reduce the weight of the vehicle and reduce fuel consumption. However, because the snow groomer is usually used...

Problems solved by technology

[0002] The snow groomer is used for pushing snow, leveling snow, laying snow, compacting snow and breaking hard snow, etc. Since the snow groomer works in the snow and the temperature is low, the low temperature resistance of the materials of the snow groomer components The requirements are relatively high. The walking part of the snow groomer is composed of a frame, a track, a suspension system, a roller, and a motor. The track is composed of a rubber composition and metal parts. The rubber composition not only has shock absorption, noise reduction, etc. It also has good physical properties and light weight, which can reduce the weight of the vehicle and reduce fuel consumption. However, because the snow groomer is usually used in a cold environment and the road is complex and harsh, the rubber in the existing track The composition is a vulnerable part, with poor low-temperature performance and short service life. In order to extend the service life of the snow groomer, ensure the safe driving of the snow groomer, and reduce the use and maintenance costs of the snow groomer, it is necessary to repair the existing snow groomer. Improve the performance of the car track rubber composition, so that it has good cold resistance, tear resistance, fatigue resistance and cut resistance

[0003] In order to solve the problems of poor low-temperature performance and short service life of existing track rubber compositions, there is an urgent need for a rubber composition for snow groomer tracks
