Description

technical field [0001] The invention relates to the technical field of rubber preparation, and more specifically relates to an environmentally friendly ethylene acrylate rubber material for automobile engine thermostats that is resistant to methanol gasoline and low temperature, and has low compression set performance. Background technique [0002] With the continuous improvement of automobile emission standards and the shortage of petroleum resources, fuel substitution and low emission are the development trends of the automobile industry. At present, some countries such as Europe and the United States have begun to replace or mix the use of a new generation of methanol gasoline (FAM experimental liquid, in line with DIN51 604-B). This fuel can not only alleviate the oil resource crisis, but also has low price, low energy consumption, and low emissions. The advantages. [0003] However, the use of the above-mentioned fuels also puts forward higher requirements on chemical ...
