Embodiment 1
[0022] In a 1.5T reactor, add 125kg of polyethylene glycol ethyl ether in sequence; triethylene glycol methyl ether borate: 855kg; 6-methyl-2-mercaptobenzothiazole: 1.5kg; methylbenzotriazepam Azole: 1.0kg; N-methyl monoethanolamine: 8kg; Antioxidant 1010: 0.9kg; 2-ethylhexyl acrylate: 1.2kg; 4,4'-butylene bis(6-tert-butyl m-cresol ): 0.4kg; methylparaben: 0.2kg; propylparaben: 0.2kg; dodecenylsuccinic acid (T746): 0.4kg; alkalinity regulator dodecahydrodiphenylamine: 6.2kg; After continuing to stir for 6 hours, it can be filtered and distributed through a 0.1um filter.
[0023] The test results of the main technical indicators are as follows (according to the requirements of the special durable metal corrosion test):
[0024]
[0025]It can be seen from the above table that DOT6 borate brake fluid has a high dry and wet boiling point that meets the requirements of GB12981-2012, and has good low-temperature kinematic viscosity. The additive formula used can meet the specia...
Embodiment 2
[0027] Add 80kg of polyethylene glycol methyl ether in sequence to a 1.5T reactor; triethylene glycol methyl ether borate: 900kg; 6-methyl-2-mercaptobenzothiazole: 1.0kg; methylbenzotri Azole: 1.0kg; N-methyl monoethanolamine: 8kg; Antioxidant 1010: 0.8kg; 2-ethylhexyl acrylate: 1.2kg; Phenol): 0.3kg; methylparaben: 0.1kg; propylparaben: 0.1kg; dodecenylsuccinic acid (T746): 0.2kg, alkalinity regulator dodecahydrodiphenylamine: 7.3kg ; After continuing to stir for 6 hours, it can be filtered and distributed through a 0.1um filter.
[0028] The test results of the main technical indicators are as follows (according to the requirements of the special durable metal corrosion test):
[0029]
[0030] It can be seen from the above table that the preferred DOT6 borate brake fluid has a high dry and wet boiling point that meets the requirements of GB12981-2012, and has good low-temperature kinematic viscosity, moderate formula cost, and excellent performance indicators .
Embodiment 3
[0032] In the 1.5T reactor, add 150kg of polyethylene glycol methyl ether in sequence; triethylene glycol methyl ether borate: 835kg; 6-methyl-2-mercaptobenzothiazole: 0.8kg; methylbenzotri Azole: 0.8kg; N-methyl monoethanolamine: 5kg; Antioxidant 1010: 0.7kg; 2-ethylhexyl acrylate: 1.0kg; phenol): 0.3kg; methylparaben: 0.1kg; propylparaben: 0.2kg; dodecenylsuccinic acid (T746): 0.3kg; alkalinity regulator dodecahydrodiphenylamine: 5.8kg ; After continuing to stir for 6 hours, it can be filtered and distributed through a 0.1um filter.
[0033] The test results of the main technical indicators are as follows (according to the requirements of the special durable metal corrosion test):
[0034]
[0035] It can be seen from the above table that the DOT6 borate brake fluid with this formula technology meets the requirements of GB12981-2012, but the dry and wet boiling points are slightly lower, and the low-temperature kinematic viscosity is good. The additive formula used can m...
