The invention discloses a refrigerant composition with a leakage stoppage function. The refrigerant composition is prepared from, by mass, 80-100 parts of fluorocarbon compound, 5-15 parts of lubricant, 0.1-1 part of corrosion inhibitor, 0.5-2 parts of extreme pressure agent, 0.5-5 parts of leakage stoppage agent and 0.01-0.1 part of nano material. The leakage stoppage agent is formed by compounding epoxy resin, organic aluminum and polypropylene glycol according to the mass ratio of 1:(0.2-5):(2-10). Organic aluminum is aluminum isopropoxide, and epoxy resin is hydroxyl epoxy resin. The refrigerant is especially suitable for various severe working environments, when leakage occurs to a system, the position where leakage occurs is automatically subjected to leakage stoppage, and therefore the service life of equipment is prolonged. The refrigerant is completely suitable for various existing air conditioning systems, has a wide use temperature range, and is free of toxic matter and beneficial for environmental protection.
Description
Technical field
The present invention relates to a kind of cold-producing medium for small-type refrigeration appliance, there is refrigerant composition earl august eugene lund ian robert of leak stopping function and preparation method thereof specifically.
Background technology
Occurring till now from refrigerant technology, vital role played the part of gradually by air-conditioning and the refrigerator of application Refrigeration Technique in the productive life of people. Manifesting and becoming increasingly conspicuous along with environmental problem, cold-producing medium also experienced by development and perfect process. Since Montreal Agreement bookmark in 1987 is ordered; various countries have carried out the research to CFCs and HCFFCs material substitute one after another; focus on ozone protection and reduce greenhouse effect; requiring that cold-producing medium not only wants ODP (OPD) value little, global warming potential (GWP) value is also little. GWP value is the number that inter-governmental climate change committee (IPCC) is determined, it refers to the amount of the global warming caused by material. The number that OPD Zhi Shi EPA specifies, it refers to and compares with Chlorofluorocarbons (CFCs)-11 (CFC0911, Arcton 11), material the ozone consumption caused.
Substituting of cold-producing medium develops with the environment of sustainable development for primary standard, and cold-producing medium also to have the Energy Efficiency Ratio being conducive to raising system, and safety is better, flammable less with toxicity, has the characteristics such as good intersolubility with lubricating oil. In addition, additive owing to containing in cold-producing medium is more, system can be produced complex impact unavoidably, can cause that the risk that leakage of refrigerant occurs improves, therefore also need to the service life adding appropriate lost circulation additive in the refrigerant to increase system, balance the negative effect that other additive brings.
CN101260287A discloses a kind of vehicle-carrying air-conditioning refrigerating system plugging agent, it consists of alkyl-silicone oil 0.1-70%, alkoxyl silicone oil 0.5-70%, hydroxy silicon oil 0.1-50%, organic amine curing agent 0.1-10%, organotin 0.1-10%, puts into dry stirred tank by each component and stirs and obtain product. Described sealing agent can form off-set layer in leakage point solidification, can be used for the leak stopping of refrigeration system component minute leakage point. But the component that the described sealing agent of this invention contains can affect refrigerating efficiency.
Summary of the invention
The present invention provides a kind of refrigerant composition earl august eugene lund ian robert with plugging effect, it is possible to meet cold-producing medium in Energy Efficiency Ratio, safety, flammable and toxicity, and the requirement of the aspect such as the intersolubility of lubricating oil, also has certain leak stopping capability simultaneously.Described refrigerant composition earl august eugene lund ian robert includes fluorocarbons, lubricant, corrosion inhibitor, extreme pressure agent, sealing agent, nano material. Form good cooperative effect between described various additive so that the refrigerant composition earl august eugene lund ian robert of the present invention has the combination property of excellence, generally, after the cold-producing medium of the system replacement present invention, the leak stopping of leakage point can be realized in start 3h.
A kind of refrigerant composition earl august eugene lund ian robert with plugging effect of disclosure, its mass fraction consists of: fluorocarbons 80-100 part, lubricant 5-15 part, corrosion inhibitor 0.1-1 part, extreme pressure agent 0.5-2 part, sealing agent 0.5-5 part, nano material 0.01-0.1 part.
Described fluorocarbons is carbon number is the alkane that replaces of the fluorine of 4-6, it will be preferred that 1,3-difluorobutane, 1,1,2-trifluoropentanes, 1,1-difluorobutane, one or more in 1,1-difluoro hexane.
Described sealing agent is epoxy resin and organo-aluminium, polypropylene glycol are composited according to the mass ratio of 1:0.2-5:2-10. Described organo-aluminium is aluminum isopropylate., and described epoxy resin is hydroxyl epoxy resin.
Described extreme pressure agent is the one two kinds in tolyl-triazole and derivant, ethoxy phosphate ester.
In in described lubricant hexamethylene, hexahydrotoluene, Pentamethylene. one or more.
Described corrosion inhibitor is diphenyl ether and derivant thereof.
Described nano material is CNT or Graphene, and the particle diameter of described Graphene is 10-100nm, and the average diameter of CNT is 10-100nm, and average length is 1-10 micron.
A kind of preparation method of the cold-producing medium with leak stopping function, according to mass ratio, nano material is added in lubricant, utilize ultrasound wave mix homogeneously, high-pressure closed vessel adds fluorocarbons according to mass ratio successively, corrosion inhibitor, extreme pressure agent, sealing agent, recycling ultrasound wave mix homogeneously, obtains described cold-producing medium. The pressure of described high-pressure closed vessel is 1-10MPa, and described container is the reactor with heating function.
The inventors have also found that after adding cycloparaffin resin in cold-producing medium, thermal conductivity and the coefficient of heat transfer occur in that bigger change, and the refrigeration performance for cold-producing medium has bigger negative effect. After adding nano material, high thermal conductivity and the coefficient of heat transfer that not only can utilize nano material self make up the impact owing to the addition of cycloparaffin resin class sealing agent brings, and nano material also utilizes the high mobility of self first to reach position micro-cracks occur, and guide sealing agent to assemble at crack location, reach better plugging effect. This is that those skilled in the art cannot expect. Applicant is it is also preferred that organo-aluminium and polypropylene glycol are as auxiliary sealing agent, and epoxy resin coordinates according to specific ratio, achieves better binding effect, and is adapted to the multiple material such as metal, plastics.
Cold-producing medium of the present invention is particularly suited for various comparatively severe working environment, when seepage occurs in system, automatically to occurring the position revealed to carry out leak stopping, thus the service life of extension device. Described cold-producing medium is completely suitable for existing various air conditioning system, has wider use temperature range, without noxious substance, is beneficial to environmental protection.
