Problems solved by technology

[0009] The above-mentioned various B-containing additives except the formula (5), the B atoms in other molecules are all combined on the molecule with the structure of the B-O bond. This structure has poor stability in the environment where water exists, especially under heating conditions. The lower B-O bond is easily broken and hydrolyzed, which cannot meet the design requirements of product performance
The patent US4743386 utilizes the Mannich reaction to form a B-N bond structure in the molecule. The B-N bond is more resistant to hydrolysis than the B-O bond. Its product can be used as a friction reducer in fully synthetic, semi-synthetic and water-based metalworking fluids, but this The product molecules only contain two active elements, N and B, which are not functional and cannot meet the lubrication and antirust requirements of water-based metalworking fluids

Embodiment 1

[0030] Dibutyl phosphite (38.8g, 0.2mol) and 36% formaldehyde (16.7g, 0.2mol) were added to the reactor, and ethylenediamine (6.1g, 0.1mol) was gradually added dropwise to the reactor while stirring In the process, control the temperature in the reactor to ≤30°C, and continue to stir for 1.5h when the temperature in the reactor no longer rises; Reflux reaction at 110°C for 4 hours. When the liquid level of water in the water separator no longer increases, the reaction ends. Cool to room temperature to obtain the target product. The chemical reaction formula is as follows:

Embodiment 2

[0033] Dibutyl phosphite (58.2g, 0.3mol) and 36% formaldehyde (25.0g, 0.3mol) were added to the reaction kettle, and diethylenetriamine (10.3g, 0.1mol) was gradually added dropwise to the reaction vessel under stirring. In the kettle, control the temperature in the reactor to ≤30°C, and continue to stir for 2 hours when the temperature in the kettle no longer rises; Reflux reaction at 130°C for 5 hours. When the liquid level of water in the water separator no longer increases, the reaction ends. Cool to room temperature to obtain the target product. The typical chemical reaction formula is as follows:

Abstract

The invention relates to amido boron phosphate, which comprises the following ingredients: organic amine, dibutyl phosphite, formaldehyde and bononizing agents according to a ratio being 1:(2-3):(2-3):1. A preparation method of the amido boron phosphate comprises the following steps that a, the dibutyl phosphite and the formaldehyde are added into a reaction kettle, then, the organic amine is completely dripped into the reaction kettle under a stirring condition, the temperature in the reaction kettle is controlled to be smaller than or equal to 30 DEG C, and the stirring is continuously carried out for 1 to 2 hours when the temperature in the kettle is not raised; b, the bononizing agents are added into the reaction kettle, a water distribution device is started, temperature is raised to 110 to 130 DEG C through heating, the backflow reaction is carried out for 3 to 5 hours, the reaction is completed when the liquid surface of water in the water distribution device is not increased, cooling is carried out to the room temperature, and a target product is obtained. The synthetized amido boron phosphate belongs to a B-N-P type multifunctional Y lubricating oil additive, when the amido boron phosphate is added into water-base metal processing liquid, the anti-corrosion performance and the anti-rust performance of the processing liquid can be improved, and the lubricating performance of the water-base metal processing liquid can also be improved.

Description

technical field [0001] The invention relates to a water-soluble antirust agent and a preparation method thereof, in particular to an amino borophosphate and a preparation method thereof. Background technique [0002] Lubrication and rust prevention are important properties of metalworking fluids, and they are also hot issues studied by scientific and technological workers in various countries. In recent years, with the enhancement of people's awareness of environmental protection and the continuous rise of oil prices, the use of fully synthetic and semi-synthetic lubricating oils is increasing, and the application range of water-based cutting fluids in metal processing is also becoming wider and wider. Therefore, the problems of lubrication and rust prevention are more prominent. In order to solve the lubricity and anti-rust properties of fully synthetic, semi-synthetic lubricating oils and water-based metalworking fluids, researchers at home and abroad have invested a lot ...
