Abstract
本发明属于高分子材料与工程领域，特别涉及一种烯丙氧基三甲基硅烷与乙酸乙烯酯的共聚物气体分离膜，解决现有高分子型气体分离膜在气体的透过性和选择性方面相互制约关系的问题。本发明专利以烯丙氧基三甲基硅烷与乙酸乙烯酯共聚制备气体分离膜。采用本体两步聚合法，在玻璃上涂膜，制得的复合高分子型气体分离膜，具有足够的稳定性、对二氧化碳具有良好的选择性和透过性。The invention belongs to the field of polymer materials and engineering, in particular to a copolymer gas separation membrane of allyloxytrimethylsilane and vinyl acetate, which solves the problem of gas permeability and selection of existing polymer gas separation membranes. issues of mutual constraints on sexuality. The invention patent prepares gas separation membrane by copolymerization of allyloxytrimethylsilane and vinyl acetate. The composite polymer gas separation membrane prepared by coating the glass with a two-step bulk polymerization method has sufficient stability and good selectivity and permeability to carbon dioxide.
Description
The invention belongs to macromolecular material and engineering field, be particularly related to the preparation method of a kind of allyloxy trimethyl silane and vinyl acetate copolymer gas separation membrane, solved existing polymer electrolyte gas separation membrane the permeability of gas and selective aspect the problem of mutual restricting relation
It is a kind of " green technology " that gas film separates, and due to it have advantages of that separative efficiency is high, it is low to consume energy, simple to operate.With the competition of traditional isolation technics in demonstrate unique advantage, its research and application development are very rapid.The macromolecule member material that has been applied to gas film separation field has polyimides (PI), cellulose acetate (CA), dimethyl silicone polymer (PDMS), polysulfones (PS), Merlon (PC) etc., but the permeability of existing polymer electrolyte gas separation membrane gas and selective aspect all exist the relation of mutual restriction, unstable chemcial property, does not also possess industrialized condition.
Selectively will relative mistake in the time that gas-premeable is good a little in order to overcome existing polymer electrolyte gas separation membrane, selective good time, the permeability of gas this problem that will be affected, patent of the present invention provides a kind of new polymer electrolyte gas separation membrane, has improved the selective and permeability of carbon dioxide.
The technical scheme that patent of the present invention adopts is: adopt polymerisation in bulk to make polymer, obtain polymer film at film on glass, concrete technology is as follows: first in there-necked flask, add successively vinyl acetate 100 parts of (molal quantity), allyloxy trimethyl silane 40-70 parts (molal quantity), 0.1～0.4 part of initator azodiisobutyronitrile (molal quantity).Then add lesser trochanter, use spherical condensation tube cooling for reflux.At 50 DEG C～70 DEG C, react 15h～25h.After pre-polymerization completes, pour reactant liquor into bottle, little bottle cap is tightened and proceeded in baking oven, continue polymerization 20h～28h at 60 DEG C～80 DEG C.Again polyvinylidene fluoride microporous film is laid on glass plate.In the time that reactant liquor becomes faint yellow sticking liquid, diluted with oxolane, be poured on polyvinylidene fluoride microporous film, through 5～8 hours, on glass plate, there will be a transparent film, taken and make off allyloxy trimethyl silane and vinyl acetate copolymer gas separation membrane.
Patent beneficial effect of the present invention is that the novel high polymer gas separation membrane making not melting under the condition of heating also just has enough stability in solvent, has preferably selectively well water-fast, heatproof and weather-proof, CO
