Problems solved by technology

[0003] However, the current sun protection and anti-corrosion methods of door panels mainly use anti-corrosion coatings. With the extension of service time, corrosion damage will occur in 1 to 2 years, and the maintenance cycle is too short, which increases the maintenance cost.

Embodiment 1

[0035] The door baffle plate for the railway box car of the present invention uses ordinary carbon steel as the substrate, and the outer surface of the substrate is provided with an impact-resistant coating, and the impact-resistant coating is coated with an anti-corrosion layer.

[0036] The impact-resistant coating is composed of the following components, 6wt% nano-zirconia, 8wt% nano-silica, 12wt% Fe, 9wt% Co, 8wt% Ni, 38% Si 3 N 4 , 15%WO and 4Wt%Dy. A shock-resistant coating with a thickness of 20 μm was prepared on the surface of the substrate by supersonic flame spraying technology.

[0037] The anti-corrosion layer includes the following components by mass, 20 parts by weight of vinyl ester resin unsaturated polyester resin, 9 parts by weight of m-phenylenediamine curing agent, 3 parts by weight of dodecyl dimethyl tertiary amine initiator, 8 parts by weight of a composite accelerator of cobalt and N,N-dimethylaniline, wherein the cobalt content is 10% by mass, 5 par...

Embodiment 2

[0043] The door baffle plate for the railway box car of the present invention uses ordinary carbon steel as the substrate, and the outer surface of the substrate is provided with an impact-resistant coating, and the impact-resistant coating is coated with an anti-corrosion layer.

[0044] The impact-resistant coating is composed of the following components, 6wt% nano-zirconia, 8wt% nano-silica, 6wt% nano-alumina, 9wt% Fe, 11wt% Co, 10wt% Mn, 37% WO, 10% Cr 3 C 2 , 1Wt%Dy and 2Wt%Na.

Abstract

The invention discloses a door baffle for a railroad box wagon. An anti-impact coating and an anti-corrosion layer are arranged on the outer surface of a base body; the anti-corrosion layer is arranged on the outer surface of the anti-impact coating. The anti-impact coating is arranged on the outer surface of carbon steel and an anti-corrosion layer is additionally arranged; the anti-impact coating is prepared from a metal and ceramic powder composite material; on one hand, the anti-impact coating has good strength, hardness and anti-impact performance of a ceramic coating; on the other hand, the added metal powder is used as a bonding phase so that a bonding property between the anti-impact coating and the base body is enhanced; and the added metal components generate an amorphous phase in a spraying process; added nanometer components are combined, so that the effects of thinning the grain size and enhancing the density of the coating are realized, and the rigidity is further improved.

Description

technical field [0001] The invention relates to an accessory for a railway freight car, in particular to a door baffle for a railway box car. Background technique [0002] A boxcar is composed of side walls, end walls, floor and roof, and is a railway wagon with sliding doors and ventilation windows on the side walls. It is used to ship valuable and goods that are afraid of the sun and rain. Some install stoves, chimneys, bed boards, etc. in the car, and can transport people and livestock when necessary. When the existing boxcar is used to transport coal and other items, the door panel is mainly a baffle structure, which prevents the leakage of goods during transportation, and can bear a certain degree of impact and anti-corrosion performance of the goods. Since the outer side of the door panel has been exposed to the outside during transportation, it should also have certain sunscreen and rainproof performance. [0003] However, the current sun protection and anti-corros...
