Background technology
Carbonic acid gas is the main gas that causes Global warming of generally acknowledging, carbonic acid gas has caused about 66% Greenhouse effect according to estimates.Since 20th century, along with the progress of science and technology, people's standard of living improves constantly, and white pollution that industrial development brings and Greenhouse effect also make mankind itself's living environment constantly worsen.Atmospheric Carbon Dioxide is become the degradable polymer plastics with synthesis of epoxy compounds, can effectively alleviate problems such as serious day by day Greenhouse effect and white pollution.Carbonic acid gas is the high-quality carbon source that a kind of cheapness should get, but because how the inertia of itself efficiently utilizes carbonic acid gas attracting various countries scientist's concern.This laboratory success utilize efficient catalyst by carbonic acid gas and propylene oxide production lined polymethyl ethylene carbonate.Lined polymethyl ethylene carbonate is a kind of degradable high polymer material with applications well prospect, and cost and common plastics are approaching.Low-molecular-weight lined polymethyl ethylene carbonate as barrier material [WO 9 925 751,1999, WO 9 925 751,1999], whipping agent [JP 08 031 700,1996], tamanori [WO 9 606 877,1996; US 5 744907,1998] research patent is appeared in the newspapers.The patent of matrix materials such as high-molecular weight lined polymethyl ethylene carbonate/natural fiber or mineral filler appear in the newspapers [CN 1422899A, 2003; CN 1422898A, 2003].But the mechanical property of copolymer lined polymethyl ethylene carbonate is relative with thermal characteristics relatively poor, and its range of application is restricted.
Summary of the invention
The objective of the invention is to overcome the relative relatively poor problem with thermal characteristics of mechanical property of existing copolymer lined polymethyl ethylene carbonate, a kind of poly methyl ethylene cyclo hexamethylene carbonate terpolymer material is provided, its mechanical property and thermal characteristics are improved greatly.
Another object of the present invention provides above-mentioned poly methyl ethylene cyclo hexamethylene carbonate terpolymer preparation methods.
To achieve these goals, the present invention adopts following technical scheme:
A kind of poly methyl ethylene cyclo hexamethylene carbonate material, its chemical structure are as (I) formula:
The preparation method of this poly methyl ethylene cyclo hexamethylene carbonate material is: putting into catalyzer, is reactant with propylene oxide and epoxy cyclohexane, and the feeding carbonic acid gas fully reacts and can synthesize poly methyl ethylene cyclo hexamethylene carbonate.
Be specially: catalyzer is added in the autoclave, whole reaction system is connected with vacuum system, the autoclave that will put into catalyzer then is 80 ℃ of following vacuum-dryings; Behind dry the end, cooling is injected a certain proportion of propylene oxide and epoxy cyclohexane in autoclave, and feeds carbonic acid gas, and heating starts and stirs, and regulates pressure carbon dioxide, and reaction system is reacted under setting pressure and design temperature; After reaction finishes, release of carbon dioxide, and with heavy-gravity mixture taking-up in the still; This mixture is dissolved in the chloroform, removes catalyzer in the system, and clean with distilled water with 5% dilute hydrochloric acid solution; With the chloroformic solution of gained co-polymer, precipitate with ethanol then, the white precipitate product of gained is a poly methyl ethylene cyclo hexamethylene carbonate.
The molar ratio of above-mentioned epoxy cyclohexane and propylene oxide is 0.01~0.10; Catalyzer is the load binary zine carboxylate; Temperature of reaction is at 60 ℃, and setting pressure is 5.2MPa, and the reaction times is 40 hours, can make the transformation efficiency of polyreaction and yield reach optimum.Can certainly add more the 3rd monomer epoxy cyclohexane, still the increase of the mechanical property of the polymkeric substance that obtains and thermal characteristics is not obvious, and the affiliation that adds of more epoxy cyclohexane increases the cost of polymkeric substance.The factor that material property is had the greatest impact is the molar ratio of propylene oxide and epoxy cyclohexane, and other factor is little to the performance impact of material.
Compared with prior art, the present invention has following beneficial effect:
Multiple aggregation is one of a polymer modification very important techniques, is one of important means that improves its performance.Through adding the 3rd monomer modified polymkeric substance its performance is significantly improved, can improve its mechanical property and thermal characteristics, thereby for the widespread use of carbon dioxide plastic provides the foundation, for the industrial applications of degradable carbon dioxide plastic has been opened up new approach.Epoxy cyclohexane has the inflexible six-ring, joins as the 3rd monomer in the copolymerization of propylene oxide and carbonic acid gas, by regulating the terpolymer that the content of epoxy cyclohexane in reaction obtains different thermal characteristicss and mechanical property.The present invention adopts propylene oxide and the epoxy cyclohexane and the carbonic acid gas of technical pure level, a kind of methyl ethylene carbonate is carried out multicomponent copolymerized and modified, and technology is simple, and raw materials cost is cheap.The gained terpolymer has physical strength and the modulus that is significantly higher than former binary polymer, and second-order transition temperature significantly raises.For the industrial applications of carbon dioxide plastic has been opened up new approach.
Embodiment
The adding of 1g load binary zine carboxylate catalyst is furnished with in the 0.5L autoclave of agitator, whole reaction system is connected with vacuum system, will put into 80 ℃ of following vacuum-drying 24h of autoclave of load weighted catalyzer in advance then.Behind dry the end, drop to room temperature, inject a certain proportion of propylene oxide and epoxy cyclohexane in autoclave, and feed carbonic acid gas, heating starts and stirs, and adjustings pressure carbon dioxide is 5.2Mpa, and reaction system was reacted 40 hours down 5.2Mpa and 60 ℃.After reaction finishes, release of carbon dioxide, and with heavy-gravity mixture taking-up in the still.This mixture is dissolved in the chloroform, removes catalyzer in the system, and give a baby a bath on the third day after its birth time with distilled water with 5% dilute hydrochloric acid solution.After then the chloroformic solution of the co-polymer of gained being adjusted to finite concentration, precipitate with ethanol, the white precipitate product of gained is terpolymer lined polymethyl ethylene-cyclohexalene carbonic ether (PPCHC).Treat to put into vacuum drying oven 80 ℃ of following bakings more than 48 hours after the trichloromethane volatilization in the white precipitate product to weight.Then polymkeric substance is put into vulcanizing press and pressed down the 5min straight forming at 160 ℃.The standard batten that the terpolymer of gained moulding is cut into 25mm * 1mm * 4mm carries out performance test.
