Above-mentioned a kind of special-purpose deicing preparation methods of salt formula bituminous pavement of holding is characterized in that it comprises the steps:
1) by the shared mass fraction of each component is: inorganic freezing point decline host 20-40 part; Depressant prescription 10-30 part under organic auxiliary freezing point; Freeze delayed-action activator 5-25 part, ice sheet tenderizer 5-25 part discharges stablizer 30-60 part; Choose depressant prescription under inorganic freezing point decline host, the organic auxiliary freezing point, freeze delayed-action activator, ice sheet tenderizer and discharge stablizer, subsequent use;
2) with inorganic freezing point decline host and the opening for feed that discharges stablizer adding fluidized bed pelletizer; Open bottom air, mix 5-10min (let two kinds of components under the fluidized-bed bottom air blows, be in fluidization, and reach purpose of mixing); Depressant prescription under organic then auxiliary freezing point, freeze delayed-action activator, ice sheet tenderizer and atomize in the bed that sprays into fluidized bed pelletizer after mixing by pressurized air through infusion set that (powder rolls through boiling and forms bigger particle gradually; This method advantage is that operations such as mixing, granulation, drying are once accomplished in an airtight fluidized-bed, and the operational safety hygienic and convenient is fit to product prepn of the present invention; The particulate of making meets necessary requirement fully); Mix, granulation, drying, what obtain particle diameter and be 0.5mm-2mm holds the special-purpose deicing material of salt formula bituminous pavement.
The invention solves the current salt formula bituminous pavement deicing material property the released shakiness of holding, the deicing effect that causes is not lasting, and the ice-melt function singleness; Resist the insufficient situation of complicated ice and snow weather ice-melt effect; And improve deicing material part component damage to the environment, reduce the problem of pavement life
Deicing material of the present invention is applied to hold the salt bituminous concrete pavement; Can descend at the ice and snow environment and hang down the freezing temperature of road surface snow-broth; Low temperature postpones the icing time on road surface down, and utmost point low temperature descends and hangs down the hardness of road surface ice sheet, and many-side reaches snow melt deicing purpose; And the speed that stable deicing component discharges has significantly improved the long-term deicing effect on active deicing road surface under complicated ice and snow environment.Product fraction environmental protection of the present invention has reduced the infringement on snow melt deicing agent environmental pollution and road surface, and easily manufactured, with low cost.Can be widely used in the active deicing of bituminous pavement under road and bridge and other the various envrionment conditionss.
Deicing material of the present invention not only makes the road deicing effect obviously strengthen, and can tackle the road accumulated snow that causes under the various weather conditions and freeze, and the release of snow melt ability is stable, has fewer environmental impacts, and reaches environmental requirement.
Beneficial effect of the present invention:
1, several kinds of components of the present invention acting in conjunction under the subzero temperature environment; Reach the maximized effect of deicing under the ice and snow weather; Many-sided road surface traffic safety that guarantees; For long-time subzero temperature ice and snow environment, the effect under the mal-conditions such as utmost point low temperature environment is good, makes this product have the wide scope of application.
Depressant prescription all has the effect of the freezing point that reduces water under inorganic freezing point decline host of the present invention and the organic auxiliary freezing point, and the theoretical basis of dependence is depression of the freezing point theory: so-called zero pour is meant that certain material liquid state and solid-state two is in balance, the temperature when both can coexist each other mutually.When neat solvent (such as water) when reaching freezing point temperature, solid, liquid two-phase reaches balance, and both partial potentials equate.When a certain amount of solute is dissolved in solvent formation dilute solution, its zero pour will be lower than the zero pour of neat solvent, be called depression of the freezing point.The present invention adopts organic and inorganic compound freezing point decline scheme and since inorganic and organic constituent with the ice and snow contact process in the mode of action different, under a stable condition, can significantly increase the action effect of Snow Agent.
Freezing delay agent the reach the freezing point frozen water of temperature of part is not temporarily frozen among the present invention; Prolong its time under supercooled state; Stop it to undergo phase transition, the time that begins to freeze lags behind, and has reduced the pressure that road freezes; During this period of time make not accumulated snow, icing of road, guarantee road traffic safety.N in this component, dinethylformamide, DMAC N,N, N; N-dihydroxy ethyl long chain fatty acids amides, ZX-I, or the maleic anhydride isobutene polymer plays a role to the frozen water system under state at negative temperature, because water freezing needs the nuclei of crystallization; And producing nuclei of crystallization needs nucleus to generate ability; When if the nuclear size that forms does not reach critical radius, just can't stable existence and growth, the delay agent ten minutes that freezes provided by the invention is adsorbed by aqueous solution intermediate ion " impurity " easily; And can change the surface energy of these " impurity ", thereby play the icing effect that postpones.The adding of this kind component has prolonged the time that ice begins to freeze greatly, has reduced possibility icy on road under the freezing temperature within a certain period of time.
Ice sheet tenderizer among the present invention can reduce the hardness of the back ice sheet that freezes, and experiment finds that behind the adding ice sheet tenderizer, the surface of ice no longer is fine and close, and becomes fluffy, becomes layered arrangement.After volume reached certain proportion, no longer densification was just iced in crystallizing into of solution, and the penetration degree test value of ice face significantly improves; This principle mainly is that the denseness of the aqueous solution improves after adding the ice sheet tenderizer, thereby has changed the direction and the speed of water crystallization body development growth; Making ice-nucleus is not that each is to orderly tight growth; Simultaneously, the ice sheet tenderizer also plays the effect of isolating ice crystal nucleus, makes ice no longer hard.In case under serious ice and snow environment, live through long subzero temperature, cause a large amount of ice and snow to freeze, loose ice sheet can not have a strong impact on traffic yet, under wheel rolls, is easy to fragmentation, and de-icing work is carried out easily.
2, this product has good release stability, guarantees that the road surface still can possess basic deicing function after long-time the use.Because the staple that the present invention discharges stablizer is cement and slaked lime, particle fineness is less, and can disperse solid-state deicing component fully after other solid ingredient grindings mix; And, be dispersed in the upper layer of bituminous pavement, owing to has certain hydration through forming fine particle with the liquid composition mixing granulation; Can be fixed gradually in compound, forming with cement, slaked lime is skeleton, wherein is dispersed with the small-particle of deicing component in the UNICOM duct; Under sleety weather, the deicing material dissolves on top layer is gone into rainwater, reaches to suppress the effect of freezing; Because the skeleton consolidation that discharges stablizer is arranged, inner snow melt component progressively is released into particle surface through suction function capillaceous; Its dissolution rate has obtained better controlled, and the deicing effect also satisfies the road surface request for utilization fully.The effect of antistripping has also been played in the adding of cement in addition, has improved the bad ability of road surface opposing damage by water, has promoted the use properties on road surface.
3, this deicing material is formed in the design; Reduced the content of inorganic component; And having selected the calcium chloride that has fewer environmental impacts for use is inorganic freezing point decline host; And utilize stablizer to solidify the deicing component that easily environment is polluted, and greatly reduce the pollution condition of Snow Agent to environment, also reduced the damaged condition of using the Snow Agent road pavement.
4, this product processes is simple, and the starting material acquiring way is easy and convenient, has significantly reduced the road surface deicing operating cost.
