Abstract

The invention provides an electric vehicle coolant, which is composed of the following raw materials in weight percentage: 0.5-3% of acrylic acid-sulfonate-amide-based copolymer; acrylic acid-acrylate-phosphonic acid-sulfonate 1- 3%; 5‑nitrobenzotriazole 0.01‑1%; 2,4,6‑tris(aminocaproyl)‑1,3,5‑triazine 0.1‑2.0%; sodium hydroxide 0.5‑1.0 %; water 30‑60%; defoamer 0.001‑0.1%; balance of ethylene glycol. The electric vehicle cooling liquid of the invention has excellent corrosion inhibition performance of aluminum-magnesium alloy, good heat exchange performance and compatibility with PVC, EPDM rubber and styrene-butadiene rubber.

Description

technical field [0001] The invention relates to an electric vehicle cooling liquid, in particular to an electronic equipment cooling liquid and a preparation method thereof, belonging to the field of chemical industry. Background technique [0002] Existing automotive lithium batteries generate heat due to chemical reactions when generating electricity. When the temperature rises above 45°C, the power generation performance decreases, and a cooling system needs to be installed. During the high temperature season in summer, the full operation of the cooling system can reduce the efficiency and shorten the driving distance by about 30%. The cooling of the battery is not the same as the cooling of the engine. The coolant of the engine can be circulated to the radiator to dissipate the heat through the convective air, the greater the temperature difference between the outlet and the inlet, the better. But the battery is not good. If the temperature difference exceeds 3°C, the ...
