High-temperature anti-corrosion coating of railway track base plate tool steel material

Abstract

The invention discloses a high-temperature corrosion-resistant coating of a railway track base plate tool steel material, which comprises a first high-temperature corrosion-resistant coating, a second high-temperature corrosion-resistant coating and a third high-temperature corrosion-resistant coating. The following components of the first high-temperature corrosion-resistant coating in parts by weight: 50-80 parts of epoxy resin, 4-22 parts of a curing agent, 6-18 parts of a functional filler, 0.5-3 parts of a pigment, 1-4 parts of an antifoaming agent, 0.5-2 parts of a degassing agent, 1-4 parts of a leveling agent, 3-4 parts of a sand streak agent, 0.5-1.5 parts of a dispersant and 1-5 parts of graphene. The second high-temperature corrosion-resistant coating is prepared from the following components in parts by weight: 50-90 parts of aluminum oxide powder, 5-7 parts of aluminum oxide fibers and 20-40 parts of zinc white powder. By arranging the first high-temperature anti-corrosion coating, the second high-temperature anti-corrosion coating and the third high-temperature anti-corrosion coating, the high temperature resistance and corrosion resistance of the high-temperature anti-corrosion coatings are effectively improved, and therefore the service life of the base plate material is prolonged.

Description

technical field [0001] The invention belongs to the technical field of track backing plates, and in particular relates to a high-temperature anti-corrosion coating for iron and steel materials used in railway track backing plates. Background technique [0002] Most of the traditional high-speed railways, railways, and urban railways use steel sleepers or wooden sleepers, and then some backing plates are used between the steel sleepers or wooden sleepers to increase the bearing capacity. However, various track backing plates on the market are made of steel materials. There are still various problems. [0003] Such as authorized announcement number is CN109929299A disclosed coating for iron and steel materials, although it realizes that a layer of anti-corrosion coating can be formed on the surface of iron and steel materials, has superior anti-corrosion performance, but does not solve the high temperature anti-corrosion of existing iron and steel materials There are still pr...

AI Technical Summary

Problems solved by technology

[0003] Such as authorized announcement number is CN109929299A disclosed coating for iron and steel materials, although it realizes that a layer of anti-corrosion coating can be formed on the surface of iron and steel materials, has superior anti-corrosion performance, but does not solve the high temperature anti-corrosion of existing iron and steel materials There are still problems in the coating: the traditional high-temperature anti-corrosion coating of steel materials generally has only one layer of structure. After use, it is easy to be scratched and damaged, which greatly reduces the high temperature resistance and corrosion resistance of the material. , thereby reducing the service life, so we propose a high-temperature anti-corrosion coating for iron and steel materials for railway track backing plates
