Abstract

The invention relates to a cooling liquid and a preparation method thereof. The cooling liquid comprises the following components in parts by weight: 2-8 parts of a metal corrosion inhibitor, 0.1-5 parts of carbon nanotubes, 0.2-10 parts of a dispersing agent, 80-120 parts of an anti-freezing agent and 70-110 parts of a solvent. The cooling liquid provided by the invention has excellent heat transfer performance and metal corrosion inhibition, and is suitable for long-term use at a relatively high working temperature.

Description

technical field [0001] The invention relates to the technical field of cooling liquid, in particular to a cooling liquid and a preparation method thereof. Background technique [0002] The low-carbonization of the automobile industry has reached a broad consensus. In response to the increasingly severe pressure on environmental protection, major global car companies have set their own energy-saving and emission-reduction targets in their development plans for the automotive industry. The realization of the goal of energy saving and emission reduction depends on the development of vehicle lightweight, electrification, intelligence and engine energy saving technologies. With the continuous improvement of engine technology, in-cylinder direct injection technology and turbocharging technology are more and more applied to the automobile industry. In-cylinder direct injection technology and turbocharging technology can precisely control the fuel injection amount according to the...
