Problems solved by technology

[0002] Friction and wear have always been a big problem for all engineering manufacturing industries. With the current vigorous development of industry, industrial lubrication performance is also constantly seeking higher evolution. When mechanical components are running, friction between metal surfaces is repeated, cycle The longer the time, the metal surface will wear and tear, and the metal powder caused by the wear will continue to cause secondary wear and scratches on the metal actuating surface, the mechanical actuating resistance will increase, and the performance will decrease, thereby reducing the life of the equipment and increasing the cost.

Embodiment example 1

[0025] The nano-titanium oxide anti-wear additive comprises: 93% of base oil; 3% of nano-titanium oxide; and 4% of pentaerythritol ester.

[0026] Wherein, the preparation method of nano-titanium oxide is:

[0027] Weigh 14.8g of titanium nitrate, 60g of pure water, and 3.75g of glycine, of which 0.05mol of titanium nitrate, 0.05mol of glycine, and a concentration of 4.44g / mol of titanium nitrate solution are put into a magnet and heated and stirred at 120°C 24h, until the water in the solution is completely evaporated and the gel appears. Put the sample on the heating plate in the fume hood at a temperature of 300-320°C. When the water reaches the critical point of complete drying, the gel solution will undergo a combustion reaction. , In a very short time, the instantaneous combustion reaction synthesizes nano-titanium oxide. Wherein, the particle size of the nano-titanium oxide is 100-200nm.

Embodiment example 2

[0029] The nanometer titanium oxide anti-wear additive, calculated by weight percentage, includes: 97% of base oil; 1% of nanometer titanium oxide; and 2% of sulfurized isobutylene.

[0030] Wherein, the preparation method of nano-titanium oxide is:

[0031] Weigh 17.76g of titanium nitrate, 60g of pure water, and 4.5g of glycine, of which 0.06mol of titanium nitrate, 0.06mol of glycine, and a concentration of 5.33g / mol of titanium nitrate solution are put into a magnet and heated and stirred at 130°C 20h, until the water in the solution is completely evaporated and the gel appears, put the sample on a heating plate in a fume hood at a temperature of 300-320°C, when the water reaches the critical point of complete drying, the gel solution will undergo a combustion reaction , In a very short time, the instantaneous combustion reaction synthesizes nano-titanium oxide. Wherein, the particle size of the nano-titanium oxide is 100-200nm.

Embodiment example 3

[0033] The anti-wear additive of nano titanium oxide, calculated by weight percentage, includes: 95% of base oil; 2% of nano titanium oxide; and 3% of sulfurized calcium alkylphenate.

[0034] Wherein, the preparation method of nano-titanium oxide is:

[0035] Weigh 23.7g of titanium nitrate, 60g of pure water, and 6g of aminoacetic acid, of which 0.08mol of titanium nitrate, 0.08mol of aminoacetic acid, and a concentration of 7.11g / mol of the titanium nitrate solution are placed in a magnet and heated and stirred at 100°C for 28h , until the water in the solution evaporates completely and becomes gelatinous. Put the sample on a heating plate in a fume hood at a temperature of 300-320°C. When the water reaches the critical point of complete drying, the gelatinous solution undergoes a combustion reaction. In a very short time, the instant combustion reaction synthesizes nano-titanium oxide. Wherein, the particle size of the nano-titanium oxide is 100-200nm.
