Abstract

The invention relates to the technical field of rail transit, and discloses a manufacturing method of an insulating part for rail transit, which comprises the following steps: adding an organic compound A, a catalyst A and a catalyst B into a reaction chamber with the temperature of 139 DEG C, carrying out addition polymerization reaction for 1-2 hours, and standing for 2-3 hours after the addition polymerization reaction is completed to obtain a polymer A. The polymer A is prepared by the following steps of: adding the polymer A into the reaction chamber; according to the manufacturing method of the insulating part for the rail transit, an organic compound A, a catalyst A and a catalyst B are subjected to vapor deposition polymerization operation at a specific temperature, a polymer A obtained after standing is conducted for three hours is polypropylene, the polypropylene is an organic substance with extremely high insulating performance, and the marble particles are filled in the polypropylene, so that the insulating part for the rail transit is obtained. And the insulation material A is used as a rail insulation material of the base layer, so that the compression resistance stability can be enhanced, the insulation capability can be greatly improved, the manufacturing mode of the insulation part is simple, and the manufacturing efficiency of the insulation part is greatly improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method for manufacturing an insulating part for rail transit. Background technique [0002] Rail transit refers to a type of vehicle or transportation system that operating vehicles need to run on a specific track. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of trains and railway technologies, There are more and more types of rail transit, which are not only used in long-distance land transportation, but also widely used in short- and medium-distance urban public transportation. [0003] Rail transit needs to use a variety of insulating parts to provide good insulation for the rails. There are many types of insulating parts on the existing market. For example, Chinese patent CN 102585364 B discloses an insulating buffer pad for rail transit rails. The material and its preparation ...
