Besides, said invention also provides the concrete steps of its preparation method, and provides its application range.
Description
Technical field
The present invention relates to a kind of composition, high-temperature chain oil and concocting method thereof especially are applicable to the low evaporation of equipment chain greasisngs such as heat setting machine, baking finish line, high temperature oven, the clean compound ester type high temperature chain oil that detergency is good.
Background technology
At present, the used chain oils of the high temperature oven of known dyeing heat setting machine, baking finish line and other industries is formed polyether-type, pentaerythritol ester type or the trimellitate type of mostly being.The polyether-type high-temperature chain oil has the good characteristics of lubricity, but its Applicable temperature is lower, generally is applied to the lubricated of the heat setting machine chain of setting temperature below 180 ℃; Tetramethylolmethane ester type high temperature chain oil Applicable temperature can reach 250 ℃, but at high temperature vaporization losses is bigger; Trimellitate type chain oils high temperature detergency ideal, but have the defective of poor lubricity.
Summary of the invention
The purpose of this invention is to provide a kind of clean compound ester type high temperature chain oil and concocting method thereof that can be applicable to heat setting machine, baking finish line and baking oven, not only Applicable temperature can reach 260 ℃, and has the characteristics that vaporization losses is little, coking is few, detergency is good under hot environment.
Technical scheme of the present invention is: a kind of clean compound ester type high temperature chain oil, by following component by weight percentage composition be: dipentaerythritol complex ester 40～90%, Pyromellitic Acid ester 10～50%, high-temperature antioxidant 1～5%, extreme pressure/antiwear agents 1～5%, corrosion inhibitor 0.02～0.5%.Wherein, described high-temperature antioxidant is an amine type oxidation inhibitor compound; Described extreme pressure/antiwear agents is at least a kind of or its mixture in thiophosphatephosphorothioate, the phosphoric acid ester; Described corrosion inhibitor is two benzotriazoles.The base oil of forming high-temperature chain oil adopts the dipentaerythritol complex ester, and adjusts viscosity with the Pyromellitic Acid ester, to reach suitable base oil viscosity requirement; Additive is selected efficient high-temperature antioxidant, extreme pressure/antiwear agents and corrosion inhibitor for use.
The base oil that the present invention selects for use: dipentaerythritol complex ester base oil structure is shown in (A); 40 ℃ of kinematic viscosity of Pyromellitic Acid ester are 40～180mm
2/ s.

The additive that the present invention selects for use: high-temperature antioxidant is an amine type oxidation inhibitor compound; Extreme pressure/wear preventive additive is thiophosphatephosphorothioate, phosphoric acid ester or its mixture; The rut preventives that adopts is two benzotriazoles.
Each set of dispense of the present invention is such as following table:
| Title | Weight part (%) |
| Base oil: bipentaerythrite complex ester Pyromellitic Acid ester additive: high-temperature antioxidant extreme pressure/antiwear agents corrosion inhibitor | ? ????40～90 ????10～50 ? ????1～5 ????1～5 ????0.02～0.5 |
Allocation process in turn includes the following steps:
(1) high-temperature antioxidant, extreme pressure/wear preventive additive, corrosion inhibitor and the heating of Pyromellitic Acid ester and stirring are warming up to 90～100 ℃, insulation 0.5～1h makes the solid materials dissolving fully;
(2) add the dipentaerythritol complex ester again, 70～80 ℃ of temperature controls continue to stir 1h;
(3) be cooled to below 50 ℃ and filter with 500 order industrial filter cloths.
Wherein, dipentaerythritol complex ester weight percentage (%) is: 40,45,50,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,85,90:
Pyromellitic Acid ester weight percentage (%) is: 10,20,30,40,50;
High-temperature antioxidant weight percentage (%) is: 1,1.5,2,2.5,3,3.5,4,4.5,5;
Extreme pressure/antiwear agents weight percentage (%) is: 1,1.5,2,2.5,3,3.5,4,4.5,5:
Corrosion inhibitor weight percentage (%) is: 0.02,0.05,0.08,0.1,0.15,0.2,0.25,0.3,0.35,0.4,0.45,0.5
Superiority of the present invention is: prepared high-temperature chain oil is 260 ℃ and lubricating with lower chain applicable to envrionment temperature.Because the dipentaerythritol complex ester base oil high high-temp stability that adopts is good, can reduces lubricating oil and use consumption.Cooperate high performance amine type oxidation inhibitor compound, high temperature produces greasy filth down, coking is few, can keep the chain cleaning for a long time.Specific dipentaerythritol complex ester base oil has extremely excellent oilness, helps the chain wear protection, and can reduce the equipment operation energy consumption.
