Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a weather-resistant glass fiber reinforced PA66 high-speed rail track sleeve material and a preparation method thereof. Background technique [0002] High-speed railway refers to the railway system that makes the operating speed reach more than 250 kilometers per hour through the transformation of the original line or the special construction of a new "high-speed new line". The development of high-speed railways is changing with each passing day, which facilitates people's travel, but this contribution is not only due to high-speed railways, many of which also play a big role. For example, track sleeves are key components of high-speed railway tracks. The production and use of the track is related to the use mission of the track and the safe driving of the locomotive. Polymer materials with light weight, high strength, corrosion resistance and easy molding ...
