Abstract

The invention provides a production method of a steel waste heat blackening agent. The method comprises the following steps: adding required water, carbon black, acetate resin and a wetting dispersantinto a reaction kettle, and stirring the water, the carbon black, the acetate resin and the wetting dispersant at a stirring rate of 50-120 r / min at the temperature of 20-35 DEG C for 5-8min so as toobtain a mixture A; and mixing raw materials, namely adding a water-based pigment into the mixture A, and dispersing the water-based pigment into the mixture A at a controlled stirring speed of 30-90r / min to obtain a mixture B. Compared with existing waste heat blackening agents, the blackening agent of the invention can form a compact double-layer blackening film on the surface of a workpiece,and the double-layer blackening film has high corrosion resistance, so that the corrosion resistance of the workpiece is greatly improved; and in addition, inorganic components and organic componentsused in the blackening agent do not pollute the environment.

Description

technical field [0001] The invention relates to a method for producing a steel waste heat blackening agent, which belongs to the technical field of steel anticorrosion. Background technique [0002] In the prior art, the black process refers to the formation of a dense black protective film layer on the surface of a metal workpiece by physical or chemical methods, thereby enhancing the anti-rust ability of the workpiece and beautifying the appearance of the workpiece at the same time. According to the different film-forming principles, the blackening process can be divided into oxidation blackening, normal temperature blackening, phosphating blackening and waste heat blackening. [0003] Waste heat blackening is to use the waste heat of the workpiece during heat treatment or other processing to make the steel workpiece form a black polymer resin film on the surface at the moment of contact with the blackening liquid, which is firmly bonded and not easy to fall off. The proc...
