Abstract
The invention relates to the technical field of axis part production and machining, in particular to quenching liquid for abrasion-resisting parts of an automobile. The quenching liquid comprises components, by mass fraction, including 15%-25% of polyoxyethylene ether, 5%-10% of triisopropanolamine, 5%-8% of polyving akohol, 3%-8% of acrylic ester, 6%-12% of sodium hydroxide, 0.1%-2% of an additive, 0.05%-0.22% of ammonium borate and the balance water. According to the quenching liquid, a formula is reasonable, no pollution is caused, the quenching effect is good, the quenched part can reach relatively high hardness, and hardness is uniform.
Description
Technical field
The present invention relates to axial workpiece production and processing technical field, particularly belongs to a kind of quenching of the wear-resisting class part of automobile
Agent.
Background technology
Quenching oil is a kind of process oil, is used as hardening media.Quenching oil must possess following characteristic：Good cooling
Energy, high-flash and burning-point, good thermal oxidation stability, low viscosity, water content are low.In addition to above-mentioned characteristic, quenching oil is also
Should nontoxic, tasteless, disposable, environmentally safe, and make the surface of the work after quenching light.Can be divided into according to cooling velocity：
Conventional quenching oil；Fast quenching oil；Overspeed quenching oil.Overspeed quenching oil has quickish cooling velocity, compares fast quenching oil
Faster.The oil is to add in refined paraffin wax based lubricating oil to urge the modulation such as cryogen, detersive and antioxidant to form.Oil temperature is 800
DEG C when its characteristic temperature be not less than 585 DEG C, it is more shorter than fast quenching oil by 800 DEG C of times for being cooled to 400 DEG C.In use,
Organic solution after heated can accelerated ageing so as to which cooling characteristics change, and such as changes not in time, will make heat treated article matter
Amount declines, or even unqualified.Quenching medium also ununified for the Quenching Treatment of high-abrasive material workpiece in the market is wear-resisting
Material quenching processing technology is the important step for feeling its workpiece toughness, and research and development high-abrasive material class quenching medium is necessary.
The content of the invention
For the problems referred to above, it is an object of the invention to provide a kind of quenching medium of the wear-resisting class part of automobile, formula is closed
Reason, pollution-free, quenching effect is good, and quenching part can reach higher hardness, and hardness is uniform.
The technical solution used in the present invention is as follows：A kind of quenching medium of the wear-resisting class part of automobile, its component and its quality
Fraction is as follows：APEO 15～25%, triisopropanolamine 5～10%, polyvinyl alcohol：5～8%, acrylate 3～8%,

Further limit, the additive includes defoamer 0.05～0.15%, preservative 0.1～0.4%, antirust agent
0.2～0.5%, lubricant 0.2～0.5%, bactericide 0.1～0.6%.
Further limit, the defoamer is organosiloxane.
Further limit, the preservative is Sodium Benzoate.
Further limit, APEO 15%, triisopropanolamine 5%, polyvinyl alcohol 5%, acrylate 3%, hydrogen-oxygen
Change sodium 6%, additive 0.1%, ammonium borate 0.05%.
Further limit, described APEO 25%, triisopropanolamine 10%, polyvinyl alcohol 8%, acrylate
8%th, NaOH 12%, additive 2%, ammonium borate 0.22%.
Further limit, described APEO 20%, triisopropanolamine 8%, polyvinyl alcohol：6%th, acrylate
6%th, NaOH 10%, additive 1.2%, ammonium borate 0.15%.
Compared with the prior art, beneficial effects of the present invention are as follows：
Rationally, quenching part can reach higher hardness to inventive formulation, and hardness is uniform, can be used for direct quenching, forge
Immediate quenching and sensing flash quenching, particularly for the quenching of big workpiece；NaOH used in the present invention can quench
The oxide skin on part surface interacts, and produces hydrogen, makes oxide skin rapid deterioration, makes quenching part surface that the silvery white of light is presented
Color；Low-temperature space cooling velocity is slower than water, and quenching part deforms little, not easy to crack, surface-brightening.
