Problems solved by technology

[0002] In recent years, water-based lubrication has replaced oil-based lubrication and has become an important development direction in the field of lubricants. Water-based lubricants are mainly used in precision polishing, cutting and cold rolling. The water cooling performance is good, and the danger of fire is reduced during the use of water lubrication, but the existing water-based lubricating oil is easily polluted, resulting in short service life and poor extreme pressure lubrication performance

preparation example Construction

[0019] According to the present invention, the preparation method of described polyurethane prepolymer comprises:

[0020] Step 1: react hydroxyl-terminated silicone oil and toluene diisocyanate to obtain the first prepolymer; the reaction temperature of the step 1 is preferably 80-90°C, and the reaction time is preferably 3-5h. Hydroxyl-terminated silicone oil and toluene diisocyanate The mass ratio of (30-40):(10-20), more preferably 35:15.

[0021] Step 2: reacting the second prepolymer with stannous octoate to obtain a polyurethane prepolymer, the reaction temperature of the step 2 is preferably 70-90°C, and the reaction time is preferably 1-2h. The mass ratio of hydroxyl-terminated silicone oil to stannous octoate is 35:2.

[0022] The preparation method of a kind of bionic structure water-based lubricating fluid of the present invention comprises:

[0023] Mix polyurethane prepolymer, 3-aminopropyltriethoxysilane, triethanolamine borate, triethanolamine oleate, ethylen...

Embodiment 1

[0026] 35 parts by weight of hydroxyl-terminated silicone oil and 15 parts by weight of toluene diisocyanate were reacted at 85°C for 4 hours to obtain the first prepolymer;

[0027] React the second prepolymer with 2 parts by weight of stannous octoate at 80° C. for 1.5 h to obtain a polyurethane prepolymer.

[0028] 70 parts by weight of polyurethane prepolymer, 25 parts by weight of 3-aminopropyltriethoxysilane, 9 parts by weight of triethanolamine borate, 9 parts by weight of triethanolamine oleate, 6 parts by weight of ethylene glycol, 1.5 parts by weight Polydimethylsiloxane, 1.5 parts by weight of simethicone oil and 180 parts by weight of water were mixed and stirred for 12 minutes to obtain a water-based lubricating fluid with a biomimetic structure.

[0029] The extreme pressure lubrication performance of the water-based lubricating fluid obtained in Example 1: PD is 762Kg, PB is 118Kg, and the service life is prolonged.

Embodiment 2

[0031] The preparation of polyurethane prepolymer is the same as in Example 1.

[0032] 60 parts by weight of polyurethane prepolymer, 20 parts by weight of 3-aminopropyltriethoxysilane, 8 parts by weight of triethanolamine borate, 8 parts by weight of triethanolamine oleate, 5 parts by weight of ethylene glycol, 1 part by weight Polydimethylsiloxane, 1 part by weight of simethicone oil and 150 parts by weight of water are mixed and stirred for 12 minutes to obtain a water-based lubricating fluid with a biomimetic structure.

[0033] The extreme pressure lubrication performance of the water-based lubricating fluid obtained in Example 2: PD is 744Kg, PB is 120Kg, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of lubricating fluid, and in particular relates to a water-based lubricating fluid with a bionic structure. Background technique [0002] In recent years, water-based lubrication has replaced oil-based lubrication and has become an important development direction in the field of lubricants. Water-based lubricants are mainly used in precision polishing, cutting and cold rolling. The water cooling performance is good, and the danger of fire is reduced during the use of water lubrication, but the existing water-based lubricating oil is easily polluted, resulting in short service life and poor extreme pressure lubrication performance. Contents of the invention [0003] The object of the present invention is to provide a water-based lubricating fluid with a bionic structure, which has good extreme-pressure lubricating performance. [0004] The present invention firstly provides a bionic structure water-based l...
