Abstract

The invention discloses environmental protection water-solubility quenching liquid, which, by weight, comprises components of 25-90% of polyether, 2-50% of water, 0.1-10% of triethanolamine, 0.1-10% of anticorrosive agent, 0.1-5% of dirty restrain agent, 0.1-5% of washing dispersing agent, 0.01-0.1% of antifoaming agent and 0.1-3% of fungicide. The polyether molecular weight is 30000-50000. The water-solubility quenching liquid is compounded with balanced rust-inhibiting additive and the washing dispersing agent, has great cooling speed in a high-temperature cooling stage, can refine grains, has moderate cooling speed in a low-temperature cooling stage, effectively solves cracking and deformation problems in a workpiece cooling process, and improves surface quality of a workpiece. Excellent rust-proof performance effectively protects the quenched workpiece, and rust-proof requirements between working procedures are completely met. The environmental protection water-solubility quenching liquid has prominent surface cleaning performance, scale cinder is avoided, output quantity is small, production efficiency is improved, and production cost is saved.

Description

technical field [0001] The invention relates to a quenching medium, in particular to an environment-friendly water-soluble quenching liquid, which is suitable for quenching carbon steel and alloy steel workpieces. Background technique [0002] At present, commonly used quenching media include water-based quenching agents and oil-based quenching agents. Oil-based quenching agents are likely to pollute the environment during the quenching process and generate a large amount of smoke, which greatly threatens the health of operators. In addition, mineral oil has a low flash point and is prone to Fire, unsafe to use; water-based quenching agent dissolves organic polymers in water to meet the cooling performance of the quenching agent by adjusting the concentration and temperature of the solution. The water-based quenching agent is characterized by a high cooling rate throughout the cooling process. In the high-temperature cooling stage, it can promote grain refinement and regular...
