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.
