2-Amino-2-methyl-1-propanol (AMP, CAS 124-68-5) is an organic compound with the molecular formula C₆H₁₅NO₅S and a molecular weight of 89.14. AMP can be used as a vulcanization accelerator, acidic gas absorber, and additive for coatings, with pigment dispersion, pH adjustment, and rust prevention effects. In addition, AMP can also be used as a component of metal processing Cutting fluid. CN113801724A patent has developed a metal processing Cutting fluid and its preparation method,This week, the editor of YACOO will briefly introduce the composition of the metal processing Cutting fluid.

The metal processing Cutting fluid includes the following components by weight: 10-20 parts of alcohol amine, 10-15 parts of antirust agent, 15-35 parts of base oil, 8-15 parts of synthetic ester, 2-6 parts of amide, 2-8 parts of emulsifier, 0.5-1 parts of corrosion inhibitor, 1-3 parts of metal corrosion inhibitor and 10-25 parts of water.

Among them:

The ethanolamine is obtained by compounding Triethanolamine with a special amine, which is Diethylene glycol amine or 2-amino-2-methyl-1-propanol (CAS: 124-68-5);

The antirust agent is made of film forming agent compounded with ternary organic polycarboxylic acid or dicarboxylic acid. The film forming agent is polyacid, the ternary organic polycarboxylic acid is TAT730 or NEUF485, and the dicarboxylic acid is Sebacic acid or dodecanedioic acid.

The synthetic ester is one or several combinations of trihydroxypropane oleate, Pentaerythritol oleate and tetrameric castor oleate.

The emulsifier is alkoxylated Fatty alcohol.

Corrosion inhibitors are one or a combination of benzotriazole and its derivatives.

The metal corrosion inhibitor is siloxane ketone.

The metal processing Cutting fluid uses amide and emulsifier to make the Cutting fluid have small emulsified particles, good cleaning performance, low foam characteristics and good lubrication performance; The common Triethanolamine is mixed with special amine to ensure that the product has a good antirust environment and bacteriostatic performance; The anti rust agent uses a film forming agent consisting of poly acids and ternary and binary acids, which not only has better rust resistance but also good resistance to hard water; In addition, this product does not contain substances that are harmful to the environment and human health, and has good environmental performance.
