Abstract

The invention discloses a low-carbon environment-friendly foaming agent composition, which is prepared from the following raw materials in percentage by mass: 60-98.99% of 1-chloro-3,3,3-trifluoropropene, 1-39.9% of 1,1,1,2,3-perfluoropropane and 0.01-1% of 1,2,2,3-tetrafluoropropane. A GWP value of the low-carbon environment-friendly foaming agent composition GWP value is HFC-245fa of a single working medium, the low-carbon environment-friendly foaming agent composition has the characteristics of being environmentally friendly, excellent in foaming property and small in deforming equipment transformation, the heat conductivity coefficient and the energy consumption level of a whole machine can be reduced, so that the low-carbon environment-friendly foaming agent composition becomes an optimal choice of high-performance rigid thermal insulation foam, and is an ideal choice of a foaming agent in the future.

Description

technical field [0001] The invention relates to the application field of foaming agents, in particular to a low-carbon and environment-friendly foaming agent composition. Background technique [0002] The blowing agent systems currently used in the home appliance industry (including refrigerators, freezers and water heaters) to replace HCFC-141b mainly include cyclopentane, HFC-245fa, HFC-245fa / cyclopentane, and a small amount of R-134a, 365mfc And the all-water foaming system, each has advantages and disadvantages, and the physical properties of different foaming agents will directly affect the performance of the final foam product. HFC-245faGWP value is 790, non-flammable, no need to invest in explosion-proof equipment, its foam products have lower thermal conductivity, better fluidity, better strength and dimensional stability, but its GWP value is higher, which will be used in the future Under the increasingly stringent environmental protection requirements in the world...
