Background technology
Polystyrene (PS) consumption is huge in the world at present, and only the year consumption of the U.S. just reaches more than 3,000,000 tons.In the manufacture process that the PS foam sheet is extruded, traditional blowing agent of use is fluorine Lyons and chain hydrocarbon.Fluorine Lyons can cause global warming and ozone layer consumption, by international community is forbidden; And chain hydrocarbon has inflammability, influences production safety.
CO
2Do not fire, increased the security of producing; Can ozone layer depletion, little (global warming potential of HCFC-22 is about CO to the influence of global warming
21700 times, CFCs-12 is about CO
25800 times); Low price, consumption is little, is easy to recycle, and is economical and practical; Nontoxic, be suitable for making the degradable tableware for food and drink.Therefore, comparatively speaking, CO
2It is a kind of safer blowing agent that is more conducive to environmental protection.In addition, use CO
2The PS blister pack thing of blowing agent production has better along malleability, not frangibility, and longer service life.Therefore use CO
2Making blowing agent tool on commercial Application has great advantage.
But, existing C O
2Blowing agent enters the carbon dioxide of body in injection process and the melt resolution is low, diffusance is high, cause and be difficult to mixing or mixing inhomogeneously with melt, and causing can't the ordinary production qualified product.And, and CO
2In injection process, be subjected to the influence of environment temperature and transient pressure, easily cause gasification or tie dry ice, cause CO
2Injection can not be stablized, the order of smooth foaming can't be reached.
The utility model content
The utility model technical issues that need to address just are to provide a kind of supercritical carbon dioxide blowing agent extruded plastic foam injected system, it has solved the carbon dioxide that enters body and the melt resolution is low, diffusance is high, cause with melt be difficult to mixing or mixing inhomogeneous cause can't the ordinary production qualified product problem, and CO
2In injection process, be subjected to the influence of environment temperature and transient pressure, easily cause gasification or tie dry ice, cause CO
2Injection can not be stablized, the problems such as purpose of smooth foaming can't be reached.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of supercritical carbon dioxide blowing agent of the utility model extruded plastic foam injected system, described system is by CO
2Injection device and ethanol injection device are formed;
Described CO
2Injection device comprises liquid CO

Described autoclave diaphragm low temperature injection pump is connected with same static mixer respectively with high head injection pump, and described static mixer connects energy storage canister; Described energy storage canister connects unidirectional injection valve, and described unidirectional injection valve connects the blowing agent body.
The utility model passes through CO
2Fluid reservoir self and aux. pressure make liquid CO
2Enter cryogenic refrigerating system; Avoid liquid CO through K cryogenic treatment
2High-temperature gasification, liquid CO
2Enter autoclave diaphragm low temperature injection pump by cryogenic piping: the heat that is produced for fear of injection pump self work causes CO
2Gasification, pump head and CO
2Out temperature is set to-18 to-25 ℃, and injection pump pressure is: the 30-35 MPa; According to CO
2Physical features successively carried out low temperature, secondary high-pressure is handled, and makes liquid CO
2Through CO
2The data on flows sensor can be stablized smoothly compounding aid ethanol and enter static mixer simultaneously and fully mix, and along with injected system pressure stable mixed liquor enters energy storage canister, the effect of energy storage canister mainly is to play uninterruptedly to stablize feed flow; At last by with the tank connected unidirectional injection valve of energy storage by injected system stable, continual mixed liquor is injected the blowing agent body; Reach and stablize foam production and go out qualified product.
Advantage of the present utility model has:
CO of the present utility model
2Blowing agent F22 in the alternative plastics extrusion foaming of the plastics blowing agent industry, freon etc., environmental protection, ODS is zero; Do not damage the ozone layer, price is low, is F22,1/5th of freon.Utilize CO
2The goods of foaming can discharge CO residual in the abscess when burning
2, the fire resistance of raising goods.
CO of the present utility model
2The plastics blowing agent injected system is injected stable, injection process CO
