Environmentally-friendly machine metal part rust prevention technology

Abstract

The invention discloses an environmentally-friendly machine metal part rust prevention technology, and relates to the technical filed of surface treatment. The technology comprises the steps of polishing, preparation of a water-soluble rust prevention solution, immersion, flushing, baking and natural cooling. The technology can effectively remove rust and oil stains on the surface of a metal part, allows a rust prevention and corrosion resisting layer to be formed on the surface of the metal part, and has a certain repairing effect on cracks and small pits of the metal part. The technology in the production process of a product has the advantages of simple operation, convenient purchasing of raw materials of the rust prevention solution, cost reduction, and environmental protection, and the external surface of the metal part obtained through adopting the technology has good rust prevention and corrosion resisting performances.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to an antirust process for metal parts of an environment-friendly machine. Background technique [0002] At present, most of the existing antirust agents for metal surfaces use antirust oil, and the antirust oil often contains harmful and flammable substances such as xylene and gasoline. In addition, the method of antirust treatment for metal materials is to apply oily antirust agent to the surface of the material, and the oily substance must be removed and cleaned before welding, painting, electroplating and other processes, which not only wastes time, but also Raw materials are wasted, and such anti-rust effect is single, there is no function of sterilization, anti-mildew and cleaning, some are irritating to human skin, and some even have an unpleasant smell, are toxic, or their performance is not stable enough, resulting in easy deterioration .

Problems solved by technology

[0002] At present, most of the existing antirust agents used on metal surfaces use antirust oil, and antirust oil often contains xylene, gasoline and other harmful and flammable substances.

In addition, the method of antirust treatment for metal materials is to apply oily antirust agent to the surface of the material, and the oily substance must be removed and cleaned before welding, painting, electroplating and other processes, which not only wastes time, but also Raw materials are wasted, and such anti-rust effect is single, there is no function of sterilization, anti-mildew and cleaning, some are irritating to human skin, and some even have an unpleasant smell, are toxic, or their performance is not stable enough, resulting in easy deterioration

[0003] In the prior art, most of the accessories of environment-friendly machines are made of metal. If you want the metal parts to have good functions, the material used is steel, which has high performance requirements. However, general materials are easy to rust, have low durability, and After rusting, it is not only unattractive, but also laborious to use and easy to fall off. Metal parts are prone to rust and cracks during long-term storage
