Problems solved by technology

Therefore, the present invention designs a type of ionic liquid heat transfer oil composition. By adjusting the anion and cation components and the ratio in the ionic liquid heat transfer oil composition, it can adapt to various application scenarios of heat transfer oil, and can solve the problem that existing industrial heat transfer oil products are not environmentally friendly. Practical problems such as poor high temperature thermal stability
At the same time, in order to solve a series of personnel and property safety problems such as the high kinematic viscosity of the heat transfer oil at low temperature and the excessive power of the motor during the cold start of the motor, which will cause the motor to burn out, we have developed a high-efficiency and energy-saving type suitable for low temperature environments. Ionic liquid heat transfer oil

Abstract

The invention provides an ionic liquid-based organic heat carrier material. The main component of the novel organic heat carrier material is an ionic liquid material with high thermal stability, the problems that synthetic heat-conducting oil is not environmentally friendly in the using process and mineral heat-conducting oil is poor in thermal stability are solved, the material has the advantages of high calorific value, high heat conduction efficiency, uniform heat conduction rate, high temperature control precision, odorlessness, low-pressure operation, safety, convenience and the like, the service life exceeds the market standard, and the material is low in price, environment-friendly and energy-saving; and meanwhile, aiming at the problems that the motor is burnt down due to overlarge power during cold start of the motor and the energy consumption of the motor is greatly increased in a low-temperature environment, the invention further provides an ionic liquid-based efficient energy-saving organic heat carrier material suitable for the low-temperature environment by adding an organic solvent into the ionic liquid-based organic heat carrier material, and the problems of starting and running of the organic heat carrier material in a low-temperature environment are solved.

Description

technical field [0001] The invention relates to a novel ionic liquid-based organic heat carrier material and a preparation method thereof. Background technique [0002] Heat transfer oil (Hot Oils) is a heat transfer medium, and its standard name is organic heat carrier (GB23971-2009), including heat transfer fluids (Heat Transfer Fluids), organic heat transfer media (Organic Heat Transfer Carriers), heat All organic media used for indirect heat transfer purposes such as Heating Media. According to the chemical composition and manufacturing process, it can be divided into synthetic heat transfer oil and mineral heat transfer oil.
