Problems solved by technology

[0005] Existing methods all use the addition of flame retardants or non-flammable components to improve flame retardancy, because the compatibility between flame retardants and HFO1234yf tetrafluoropropene is poor, the dispersion is uneven, and the flame retardant effect is poor. At the same time, the prepared Refrigerant products have a higher GWP than HFO1234yf single working substance, and still have a great impact on the environment

Description

technical field [0001] The invention relates to a refrigerant composition and a preparation method thereof, in particular to a fluorine-containing iodohydrocarbon composition and a preparation method thereof. Background technique [0002] As a single refrigerant, HFO-1234yf has excellent environmental parameters, its global warming potential (GWP) is 4, ozone depletion potential (ODP) is 0, and its life cycle climate performance (LCCP) is lower than that of HFC-134a. Atmospheric decomposition products are the same as HFC-134a. And its system performance is better than HFC-134a. If HFO-1234yf is used to replace HFC-134a refrigerant, automobile manufacturers can continue to use the original mobile air-conditioning (Mobile Air-Conditioning, MAC) system. Therefore, HFO-1234yf is considered to be a potential substitute for a new generation of automotive refrigerants. It has been accepted by automakers in Western Europe and will be gradually promoted in 2011. The GWP and atmosp...
