Problems solved by technology

However, the ability of additives to improve the surface problems of products is limited, and the addition of too many low-molecular-weight substances will reduce the rigidity and aging resistance of the material. Differences, easy to fluctuate during extrusion and granulation, these many unstable factors make it difficult for the product to meet the requirements of safety and high stability
The adoption of special production techniques and equipment will lead to higher production costs

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 substrate material and a preparation method thereof. Background technique [0002] The rapid development of China's high-speed rail, and the successful signing of some foreign projects, this is an opportunity for the development of China's high-speed rail. At the same time, high-speed railway has become an important part of the national economy due to its advantages of low energy consumption, high-speed safety, comfort and energy saving. Although the railway system has carried out several large-scale speed increases, the overall railway transport capacity cannot meet people's needs. An important way to solve this bottleneck is to speed up the construction of high-speed railways. An important way to speed up the development of high-speed rail is to use new materials to improve it. Polymer...
