Description
Technical Field
The invention relates to tempering liquid based on organic electrolyte with imidazole rings.
Background
The tempering heat treatment is a metal heat treatment process of reheating the quenched workpiece to a proper temperature lower than a lower critical temperature Ac1, wherein the lower critical temperature Ac1 is the starting temperature of pearlite transformation to austenite during heating, and cooling the workpiece in air or a medium such as water, oil and the like after keeping the temperature for a period of time, or heating the quenched alloy workpiece to a proper temperature, keeping the temperature for a period of time, and then slowly or rapidly cooling the workpiece. Are generally used to reduce or eliminate internal stresses in quenched steel parts or to reduce their hardness and strength to improve their ductility or toughness. The quenched workpiece should be tempered in time, and the required mechanical properties can be obtained through the matching of quenching and tempering.
Tempering is generally carried out immediately after quenching, with the aim of: (1) eliminating residual stress generated during workpiece quenching, and preventing deformation and cracking; (2) the hardness, strength, plasticity and toughness of the workpiece are adjusted to meet the requirement of service performance; (3) stabilizing the structure and the size and ensuring the precision; (4) improve and enhance the processing property. Thus, tempering is the last important process for obtaining the desired properties of the workpiece. The workpiece can obtain the required mechanical property through the matching of quenching and tempering. The tempering process comprises high-temperature tempering, medium-temperature tempering and low-temperature tempering. The low-temperature tempering temperature is 160-260 ℃ in general, and tempering heat treatment can be carried out by using tempering oil as a medium. The special tempering oil is prepared by taking deep refined mineral oil as base oil and adding various additives such as a high-temperature antioxidant, a detergent, a dispersant and the like, and at present, the mineral base oil taking hydrocarbon as a main structure is decomposed at 250 ℃ generally and generates a large amount of oil smoke because the tempering oil needs to be used at high temperature for a long time in the use process. With the increase of the service time, the oil product aging is aggravated, the generated oil smoke is greatly increased, and the body health of field operators is seriously influenced.

The metal deactivator can form a layer of passive film on the surface of the workpiece entering tempering liquid at high temperature, thereby protecting the workpiece and preventing the workpiece from being oxidized. In the using process of the tempering liquid, due to the existence of oxygen, the tempering liquid is subjected to the action of light and heat, so that the tempering liquid is oxidized, particularly, metal ions such as iron and copper are introduced when the tempering liquid is used for treating metal workpieces, the metal ions can accelerate the oxidation of the tempering liquid, and the metal deactivator can form a chelate with the metal ions and form a passive film on the surface of the metal. The metal ion catalytic tempering liquid can be used for delaying the oxidation of the metal ion catalytic tempering liquid and protecting the workpiece from being oxidized.
Has the advantages that: the tempering liquid adopts the organic electrolyte with imidazole rings, the organic group in the organic electrolyte is a cyclic conjugated five-membered ring structure of imidazole, the thermal stability of the structure is increased, and meanwhile, the long branched chain (group grafted by imidazole ring side group) in the structure can improve the melting point of the structure, so that the tempering liquid has high melting point and decomposition temperature, the decomposition temperature is as high as more than 400 ℃, and the tempering liquid can be stably used at high temperature; on the other hand, the long-chain branch in the structure can also increase the solubility of the long-chain branch with other additives, improve the stability of the system, ensure that the whole system is still uniform and stable after being used for one year, and has no problems of floating, precipitation and phase separation, and simultaneously, the long-chain branch can also increase the viscosity of tempering liquid, so that the tempering liquid can meet the application of tempering; the tempering liquid can solve the problems that the traditional mineral-based tempering oil has low decomposition temperature, is volatile, causes environmental pollution due to large oil smoke and is easy to age to influence the tempering quality of workpieces.
