Machining face anticorrosion treatment method adopting painting procedure

Abstract

The invention discloses a machining face anticorrosion treatment method adopting a painting procedure and belongs to the technical field of armored car machining. The problems that under the circumstances that a machining face of an armored car part cannot reach roughness needed by painting and oil on the machining face cannot be removed thoroughly by a common degreasing method, anticorrosion cannot be achieved through painting are solved. According to the machining face anticorrosion treatment method, oil on the surface of the machining face is removed thoroughly through electrolytic degreasing of an appropriate solution matching ratio, the requirement of a coating for roughness of the machining face of a substrate is lowered through high permeability and epoxy resin characteristics of high-strength epoxy phosphate primer, bonding strength of the coating and the substrate is enhanced, and rustproof and anticorrosion effects are achieved.

Description

technical field [0001] The invention belongs to the technical field of armored vehicle machining, and relates to a variety of parts in armored vehicles that include machined surfaces and need to be painted. Background technique [0002] During the use of armored vehicles, they often experience extremely harsh environments and withstand severe vibrations. These conditions have higher requirements for the anti-corrosion capabilities of armored components. At this stage, the anti-corrosion of parts is mainly through different types of surface treatment, among which painting is the most common method. Painting can not only play a good anti-corrosion effect, but also distinguish parts by color. The parts of the armored vehicle that need to be painted contain a variety of machined surface parts. The roughness of the machined surface that needs to be sprayed is generally between Ra1.6-12.5, but the requirements for the surface of the parts in the paint are generally sprayed. Sand ...

Problems solved by technology

[0004] The invention provides a method for anti-corrosion treatment of machined surfaces using a painting process, that is, a method for anti-corrosion treatment of machined surfaces of parts that require a painting process, which is a degreasing and painting process on the machined surface of an armored vehicle The application of the method solves the problem that the anticorrosion cannot be carried out by painting when the machined surface of the armored vehicle parts cannot reach the roughness required for painting, and the general degreasing method cannot completely remove the oil on the machined surface. Remove the oil process and combine with high-strength epoxy zinc phosphate primer to enhance the adhesion of the primer to ensure anti-rust and anti-corrosion effects
