Description

technical field [0001] The invention belongs to the technical field of high altitude cold equipment thermal insulation, and relates to a high altitude wear-resistant and rolling-resistant soft thermal insulation material and a preparation method thereof. Background technique [0002] In high-altitude and alpine regions, the temperature in winter is often below -20°C, and even reaches -40°C in many regions. Due to the influence of the extreme cold environment, the overall performance of the equipment is reduced, and the components and systems are not smooth, resulting in equipment failure. Difficult to start, high failure rate, and extremely harsh environment have brought great challenges to the rapid response and maintenance of heavy equipment. [0003] Existing thermal insulation covers used for parking heavy equipment in cold environments can only insulate the body of the equipment and cannot isolate the heat lost from the ground; and the thermal insulation covers cannot w...

Problems solved by technology

[0002] In high-altitude and high-cold regions, the winter temperature is often below -20°C, and even reaches -40°C in many areas. Difficult start-up, high failure rate, and extremely harsh environment have brought huge challenges to the rapid response and maintenance of heavy equipment

[0003] Existing insulation covers for parking heavy equipment in cold environments can only insulate the equipment body, but cannot isolate the heat lost from the ground; and the insulation cover cannot withstand high-intensity rolling and friction, which makes it unable to meet the repeated use of heavy equipment
