Problems solved by technology

[0002] Tracks can improve the passability of large construction machinery such as excavators and harvesters, but metal tracks are noisy and wear the ground seriously, and the application range is limited. Rubber tracks can greatly slow down the impact of metal tracks on the ground and avoid impact on the road (especially high-grade Highway) at the same time reduces the vibration and noise when the vehicle is running, and improves the driving speed. However, the rubber track used in construction machinery is currently poor in cutting resistance and wear resistance, which makes it easy to be damaged when driving on gravel and cement roads. , shorter driving life, higher replacement cost

The rubber track is used for manufacturing rubber tracks and can meet use requirements.

Description

Technical field [0001] The invention relates to the field of polymer materials, specifically a cut-resistant rubber crawler track for engineering machinery and a preparation method thereof. Background technique [0002] Crawler tracks can improve the passability of large engineering machinery such as excavators and harvesters, but metal tracks are noisy and cause serious wear and tear on the ground, and their application range is limited. Rubber tracks can greatly slow down the impact of metal tracks on the ground and avoid damage to the road surface (especially high-grade Highway), while reducing the vibration and noise when the vehicle is driving, and increasing the driving speed. However, the current rubber tracks used for construction machinery have poor cutting resistance and wear resistance, making them easily damaged when driving on gravel and cement roads. , the driving life is short and the replacement cost is high. Contents of the invention [0003] Purpose of t...
