Abstract

The invention discloses an antirust and anticorrosion quenching agent. The antirust and anticorrosion quenching agent is prepared from the following raw materials in parts by weight: 3-5 parts of sodium chloride, 1-2 parts of triethanolamine borate, 0.3-0.5 part of polyepoxysuccinic acid, 2-4 parts of polyethylene glycol, 1-2 parts of petroleum sodium sulfonate, 0.3-0.5 part of sodium tripolyphosphate, 0.3-0.5 part of lauryl sodium sulfate, 0.3-0.5 part of borax, 0.3-0.5 part of tartaric acid, 0.3-0.5 part of hydroxyethyl urea, 3-5 parts of auxiliaries and 70-80 parts of water. The quenching agent is non-corrosive to workpieces, and has excellent antirust and anticorrosion effects on the treated workpieces; besides, the quenching agent is good in cooling performance, long in service life, not prone to aging and deterioration, relatively high in quenching hardness, and capable of effectively reducing quenching deformation and cracking.

Description

technical field [0001] The invention relates to heat treatment technology, in particular to an antirust and anticorrosion quenching agent and a preparation method thereof. Background technique [0002] Quenching is a process in which a metal workpiece is heated above the phase transition temperature, and then rapidly cooled in a quenching medium after heat preservation to obtain a martensitic structure. Through the quenching process, the purpose of improving or adjusting the hardness and wear resistance of the workpiece can be achieved. In this process, the requirements for the quenching medium (quenching agent) are to avoid deformation and cracking of the workpiece; the quenching agent is easy to clean, does not pollute and corrode the surface of the workpiece; has stable performance, high temperature resistance, aging resistance, and is not easy to deteriorate; easy to prepare and transport And storage, safe use; raw materials are easy to get, and the cost is low.
