Rust-proof steel plate for vehicle in high-humidity environment and manufacturing process thereof

Abstract

The invention discloses a rust-proof steel plate for a vehicle in a high-humidity environment, which comprises a rust-proof steel plate assembly. The rust-proof steel plate assembly comprises a steelplate, a reinforcing groove is formed in the steel plate, a zinc sheet strip is fixedly connected into the reinforcing groove, the surface of the rust-proof steel plate assembly is sequentially coatedwith a primer layer, an anti-corrosion intermediate paint layer and an anti-corrosion finish paint layer, the zinc sheet strip and the steel plate are fixed in a welded mode, and a welding hole is formed in the zinc sheet strip. The steel plate can be protected from rusting by a sacrificial anode protection method through the zinc sheet strips arranged on the steel plate, and meanwhile, the rust-proof effect of the steel plate can be greatly improved by matching with the multiple paint layers, so that the steel plate is not easy to rust even if the paint layers partially fall off, and is convenient to use for a long time in a high-humidity environment; the zinc sheet strips are welded and fixed in the reinforcing grooves, do not affect the whole structure, are not prone to falling off andare high in stability and reliability; the manufacturing process is simple, the cost is controllable, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of anti-rust vehicle steel plates, and in particular relates to an anti-rust vehicle steel plate used in a high-humidity environment and a manufacturing process thereof. Background technique [0002] Three-wheel motorcycles or three-wheel electric vehicles have played a very important role in the transportation of short-distance small quantities of goods. The steel plates used in the three-wheel motorcycles and three-wheel electric vehicle compartments in the prior art generally all can be painted. It has only a certain anti-rust effect and can enhance aesthetics. In order to ensure the strength of use, reinforcing grooves are set on the steel plates of the carriage and other parts by bending to increase the strength. [0003] Conventional three-wheeled motorcycles or three-wheeled electric vehicles are very prone to rust in high-humidity environments, such as in seaside environments, or when they are used ...

AI Technical Summary

Problems solved by technology

[0003] Conventional three-wheeled motorcycles or three-wheeled electric vehicles are very prone to rust in high-humidity environments, such as in seaside environments, or when they are used to haul seafood and other aquatic products, which will cause damage to the three-wheeled motorcycles or three-wheeled electric vehicles. Rust on the steel plate directly affects the service life and product quality. In order to solve this problem, SUS304 stainless steel is generally used in the prior art to make transport vehicles in high-humidity environments. Not only is the cost high, but it may still occur during use. Rust, for example: when organic juices (such as vegetables, etc.) are attached to the surface of stainless steel, organic acids will be formed under the action of water and oxygen. Such as sea water, etc.), it is very easy to cause local corrosion
