Description
Technical field
The present invention relates to a kind of air conditioner rubber pipe field, in particular to a kind of R1234yf air-conditioner pipe hose lining composition, preparation method and empty soft pipe.
Background technology
Refrigeration agent is the working medium completing refrigeration cycle in process of refrigeration, and the refrigeration agents used such as early stage air-conditioning and refrigerator are halohydrocarbon.But the discharge of this halogenate hydrocarbon refrigerant can destroy atmospheric ozone layer, refrigeration agent represents the destructiveness of the ozonosphere latent value (Ozonedepletionpotential is called for short ODP) that damages the ozone layer.Simultaneously, these halohydrocarbon are also one of inducements causing global warming, because the discharge of halogenate hydrocarbon refrigerant can cause Greenhouse effect, and then cause Global warming, its influence degree global warming potential (Globalwarmingpotential is called for short GWP) represents.
Before Montreal Agreement bookmark is ordered, automotive air-conditioning system is mainly using CFC12 as refrigeration agent, but the ODP value of this refrigeration agent is higher, and thus, according to Montreal Agreement book, CFC12 is that one-level is limited refrigeration agent.
Replace CFC12 to find new refrigerant, air conditioner industry has been made and having been studied widely, ites is desirable to develop the Biological process that ODP value is zero.In these researchs, the refrigeration agent HFC134a of E.I.Du Pont Company's exploitation is successfully applied in refrigeration industry.Due to the not chloride atom of HFC134a, and have good safety performance, meanwhile, the CFC12 refrigeration agent of physical properties also with traditional of this refrigeration agent is comparatively close, and thus the remodeling of refrigeration system is also than being easier to.Further, HFC134a heat transfer character is also more excellent than CFC12, and thus, in use, the consumption of HFC134a is also less, suitableeer as air conditioner refrigerating medium.
But, according to the requirement of the fluorine-containing greenhouse-gas control regulation that European Union has passed through, from 11 days January in 2011, European Union will forbid the refrigeration agent that the automative air conditioning of new production uses GWP value to be greater than 150, because the GWP value of the HFC134a refrigeration agent used in a large number is now 1300, so will be prohibited from using.Further, European Union specifies, from 1 day January in 2017, will forbid the refrigeration agent that all automative air conditionings use GWP value is greater than 150.Thus, automative air conditioning uses low GWP to obtain refrigeration agent will become trend and certainty.
U.S. Honeywell (Honeywell) company and E.I.Du Pont Company have developed jointly novel environment-friendly refrigerant R1234yf, and its chemical name is tetrafluoeopropene, and molecular formula is CF
3cF=CH
2, the GWP value of HFO-1234yf is 4, far below the regulation of European Union's automative air conditioning instruction.Thus R1234yf is more suitable for as automobile air-conditioning refrigeration medium, and it can be used as the performance of refrigeration agent also progressively to obtain accreditation.
