Konjac extract quenching agent and preparation method thereof

Abstract

The invention discloses a konjac extract quenching agent which is characterized by comprising the following raw materials in parts by weight: 6-10 parts of a konjac extract, 1-2 parts of polyethylene glycol, 0.3-0.5 part of starch sodium octenylsuccinate, 0.3-0.5 part of disodium ethylene diamine tetraacetate, 0.5-1 part of sodium gluconate, 0.5-1 part of sodium bicarbonate, 0.01-0.02 part of oleamide, 0.3-0.5 part of zinc sulfate, 0.01-0.02 part of polyaspartic acid, 0.1-0.2 part of sodium benzoate and 80-100 parts of water. The quenching agent disclosed by the invention takes the konjac extract as a main raw material and is good in cooling performance, the quenching deformation of a workpiece can be effectively reduced, cracks and soft spots of the workpiece are avoided, and the machined workpiece is high in hardness and deep in hardening layer; and moreover, the quenching agent has the effects of preventing rust, preventing corrosion and killing bacteria, the pollutant discharge is slight, the environmental compatibility is high, and the industrial policy on environment friendliness and emission reduction is met.

Description

technical field [0001] The invention relates to heat treatment technology, in particular to a konjac extract quenching agent and a preparation method thereof. Background technique [0002] Quenching medium in heat treatment production directly affects the performance of parts after quenching, and is a key factor affecting product quality. Commonly used quenching media mainly include water, aqueous solution, oil, etc. Among them, quenching oil is very polluting to the environment, and it is easy to cause fire during quenching, so it is difficult to meet the requirements of safety and environmental protection. [0003] Water is a quenching medium with strong cooling capacity. It has wide sources, low price, stable composition and not easy to deteriorate. The disadvantage is that the workpiece is prone to "soft spots" during the cooling process, and in the martensitic transformation temperature zone, due to too fast cooling, it is easy to generate a large internal stress, resu...

Problems solved by technology

The disadvantage is that the workpiece is prone to "soft spots" during the cooling process, and in the martensitic transformation temperature zone, due to too fast cooling, it is easy to generate a large internal stress, resulting in deformation or even cracking of the workpiece

Part of the water-based quenching agent adds an appropriate amount of salt and alkali to the water, so that after the high-temperature workpiece
