Abstract

The invention provides an inverter cooling liquid. The inverter cooling liquid consists of the following raw materials in percentage by weight: 0.5-3 percent of 2-hydroxyphosphonoacetic acid, 0.2-3 percent of amyl phosphate, 0.01-1 percent of 5-carboxy benzotriazole, 0.1-2.0 percent of 2,4,6-tri-(aminocaproic acid)-1,3,5-triazine, 0.5-1.0 percent of inorganic base, 0.001-0.1 percent of antifoaming agent, 30-60 percent of water and the balance of glycol. The inverter cooling liquid has excellent corrosion inhibiting performance of an aluminum magnesium alloy, better heat exchange performance and compatibility among PVC, ethylene propylene diene monomer rubber and butadiene styrene rubber.

Description

technical field [0001] The invention relates to an engine coolant, in particular to an inverter coolant and a preparation method thereof, belonging to the field of chemical industry. Background technique [0002] At present, my country's Harmony Railway locomotives mostly adopt the AC-DC-AC electric traction mode. The locomotive uses a pantograph to receive 25kv voltage from the catenary, and then passes through the main transformer to step down the voltage, and then splits the single-phase current into three-phase current through the splitter camera. , and then through the rectifier circuit to form a DC current. After the DC power passes through the control device, it needs to pass through the inverter to change back to the AC power, and finally send it to the traction motor to drive the locomotive forward. Heat will be generated during the inverter process and needs to be cooled. System cooling. [0003] In the AC-DC electric traction mode, the DC circuit generally loses a ...
