The advantages that energy consumption is low, good separating effect, green process, thus there is good development prospect.
Existing literature is retrieved, finds the Introduction To Cn Patent that number of patent application is 201180064352.8 one kind
Carbon dioxide separation film containing water absorbent polymer, carbon dioxide carrier and polysaccharide, it is by agar, alkali carbonate
Composition is formed Deng material, is again crosslinked uncrosslinked desciccator diaphragm after film forming is dry.In addition, it with the addition of ammonia in the feed
Base acid.From principle, adsorptivity and selectivity of the film to carbon dioxide can be improved by adding amino acid；Yet with its addition
Amino acid there is very strong hydrophily and polarity, in practical operation, when separating the gas or acidic and alkaline gas containing moisture,
Partial amino-acid can be dissolved in water or change molecular conformation due to the change of acid-base property, so that the structure of film produces necessarily
Change so that the stability of film reduces, so that separating property declines.
It was found that number of patent application has been 200810001447.5 Introduction To Cn Patent, one kind contains expanded PTFE
And the carbon dioxide separation film of polysiloxanes, organopolysiloxane is cured or is cross-linked to expanded PTFE supporting layer by it
On, to obtain the high patience to harsh environment.From principle, such a carbon dioxide separation method can obtain high intensity, Gao Wen
Qualitatively big flux seperation film；In practical operation, the permeability of gas is improved to obtain big flux due to this film, institute
Not high to the selectivity of carbon dioxide with this film, separating still has certain density carbon dioxide in the gas of acquisition.
The content of the invention
It is an object of the invention to overcome above-mentioned the shortcomings of the prior art, there is provided one kind has economic, environmental protection production
The environment-friendly liquid of technique and function admirable supports carbon dioxide separation film.The preparation side of the support liquid carbon dioxide separation film
Method has the advantages that technique is simple, cost is low etc., raw material have it is relatively inexpensive be easy to get, liquid environment is friendly, low volatilization, outstanding machine
Tool intensity, chemical stabilization and heat endurance, to CO2High-solvency, the height in high selectivity and its chemical constitution and performance
The advantages that spending designability；Therefore, this support liquid carbon dioxide separation film, not only has very high dissolving energy to carbon dioxide
The advantages that power and selective penetrated property, also have higher stability, and service life is longer；It is a kind of cheap, efficient dioxy
Change carbon seperation film.
The purpose of the present invention is what is be achieved through the following technical solutions：
The invention discloses a kind of environment-friendly liquid to support carbon dioxide separation film, and the seperation film is by including by more ethene
