preparation example Construction

[0031] A kind of preparation method of quenching oil, this preparation method comprises the steps:

[0032] (1) In parts by weight, take 30~40 parts of toluene diisocyanate, 10~15 parts of polyphenylene ether, 5~7 parts of dimethylformamide, 3~5 parts of dimethylol propionic acid, 2~4 parts 1, 4-butanediol, 1~3 parts of stannous octoate, mix toluene diisocyanate and polyphenylene ether, pass through nitrogen protection, stir at a temperature of 58~60°C for 1~2h, add dimethyl formaldehyde Dilute the amide, then add dimethylolpropionic acid and 1,4-butanediol, stir evenly, add stannous octoate, and stir at a temperature of 60~65°C for 1~2h to obtain a mixture;

[0033] (2) According to the mass ratio of 1:5~7:10~15:15~20, mix the plasticizer, nitrocellulose, water, and stirring material, and stir evenly to obtain the stirring liquid, according to the mass ratio of 1:5~7 , mixing the modified nano-alumina and the extract, soaking for 1-2 hours, filtering to obtain a filter resid...

Embodiment 1

[0038] The plasticizer is phthalic acid.

[0039]The modified nano alumina is mixed with (methacryloxypropyl) trimethoxysilane, water and ethanol at a mass ratio of 1:20:50, adjusted to pH 3, stirred at room temperature for 1 hour, and added Nano-alumina with 20% water quality was heated to 40°C, stood for 4 hours, filtered to obtain a filter residue, washed with toluene, and vacuum-dried at a temperature of 58°C for 20 hours to obtain modified nano-alumina.

[0040] The extraction solution is obtained by drying pomelo peel at a temperature of 50°C and grinding to obtain a grind. The grind is mixed with an ethanol solution at a mass ratio of 1:10, and extracted at a temperature of 70°C for 1 hour to obtain an extract.

[0041] The dispersant is sodium pyrophosphate.

[0042] The initiator is potassium persulfate.

[0043] The mixture is obtained by mixing ethylene oxide and propylene oxide evenly at a mass ratio of 1:1.

[0044] The base oil is made by mixing linseed oil, m...

Abstract

The invention discloses a preparation method of quenching oil, and belongs to the field of chemical engineering. According to the preparation method, the nano aluminum oxide is modified, meanwhile, the adsorption performance of the nano aluminum oxide is utilized to adsorb an extracting solution, so that the effect of slow release is achieved; due to the fact that the molecular structure of the shaddock peel extract contains a large amount of active groups such as hydroxyl, the groups are provided with more negative charges, can provide electrons to empty tracks of the metal, and can be adsorbed on the surface of the metal, so that the effect of corrosion inhibition is achieved, then the metal can be further protected, meanwhile, the antioxidant is also added so that the oil product can beeffectively prevented from generating acidic substances in the high-temperature working state, and then the cooling performance in the long-term use process is kept continuous and stable. According to the preparation method, the problems that the cooling effect of most of the quenching oil at present is poor, and the prepared product is insufficient in glossiness are solved.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a preparation method of quenching oil. Background technique [0002] Quenching oil is a process oil used as a quenching medium. Quenching oil must have the following characteristics: good cooling performance, cooling performance is an important performance of quenching medium, its quality directly affects the quality of quenched parts, good cooling performance can ensure that the quenched parts have a certain hardness and qualified Metallographic structure can prevent deformation and cracking of parts; high flash point and ignition point, when quenching, the temperature of oil will rise instantaneously, if the flash point and ignition point of oil are low, ignition may occur. Therefore, the quenching oil should have a higher flash point and ignition point. Usually the flash point should be 60~80°C higher than the temperature of the used oil; good thermal oxidation s...
