Description
Technical field
The present invention relates to technical field of chemistry and chemical engineering, specifically, is a kind of preparation method of phase-changing energy storage material.
Technical background
The external advanced country of phase-changing energy storage material has just begun one's study as far back as twentieth century the sixties, and domestic in China, just takes up research to phase-changing energy storage material the eighties to twentieth century.Phase-changing energy storage material is of a great variety, solid can be divided into according to its phase transformation mode solid-, solid-liquid, liquid-gas, consolidate-the gas phase change energy-storage material; Can be divided into according to its chemical constitution: mineral-type, organic, complex class phase-changing energy storage material.
Described mineral-type phase-changing energy storage material mainly comprises melting salt, crystalline hydrate salt, metal and alloy, fluorochemical, atlapulgite and mineral wool.Wherein, crystalline hydrate salt is most typical inorganic-phase variable energy storage material, it mainly comprises vitriol, carbonate, nitrate, phosphoric acid salt, acetate and the halogenide of alkali and alkaline-earth metal, mainly contains the materials such as calcium chloride hexahydrate, sal glauberi, Sodium acetate trihydrate, disodium hydrogen phosphate, magnesium nitrate hexahydrate, magnesium chloride hexahydrate, Sodium carbonate decahydrate, zinc nitrate hexahydrate.After being heated, described crystalline hydrate salt can slough in conjunction with water storage power; When cooling, can release energy, be reduced to crystalline hydrate salt, by reversible phase transition process, realize storage and the release of energy.Crystalline hydrate salt has larger enthalpy of phase change and fixing fusing point, described melting range is wider, is mainly used in research and the application of middle low-temperature phase-change material, still, phenomenon cold and that be separated in use occurs easily, badly influenced the widespread use of salt hydrate.
Described organic phase-changing energy storage material be utilize transformation between the crystal formation and polymer side chain under differing temps transformation and absorb heat or heat release, it mainly comprises the polymers such as paraffin, lipid acid and ester thereof, alcohols, amides, arene and polyolefins, polymeric polyalcohols.Wherein, the advantage of paraffin phase change material is that use temperature is extensive, enthalpy of phase change is large, physical and chemical performance is stable, the cold-peace demixing phenomenon can not occur, nontoxic having no irritating odor, to container almost without the corrosion, low price; Its deficiency is, thermal conductivity is low, and energy storage density is little, and the trend of taking off wall is arranged in process of setting, so need to carry out particular design to heat reservoir, just increased the cost of using but do like this.
In any case, paraffin has as traditional solid-liquid type phase-changing energy storage material that heat storage capacity is large, transformation temperature changes, has good thermal circulation performance with the variation of relative molecular mass and have the advantages that heat storage capacity is stable, transformation behavior is stable, the source is abundant, cheap.Paraffin is mixed by straight-chain paraffin, and along with the increase of chain, fusing point and Heat of fusion increase, and its fusing point is-12～75 ℃, and Heat of fusion is 150～250J/g.Paraffin because its transformation temperature is adjustable, makes it have broad application prospects in building energy saving field as energy storage material.According to the difference of transformation temperature, different sorts or the different paraffin that forms can be applicable in phase transformation body of wall, energy storage floor, ceiling or the solar energy heat-storage.Many countries with the action oriented research of paraffin as one of main direction of development phase-changing energy storage material.
In the action oriented research of paraffin, utilize the paraffin emulsifier can be successfully with paraffin phase change material emulsification.The emulsifying agent that this respect uses can be divided into two large classes: ionic emulsifying agent and nonionic emulsifier.Wherein, ionic emulsifying agent is divided into again anionic emulsifier, cationic emulsifier and amphoteric emulsifying agent.Nonionic emulsifier commonly used has fatty alcohol-polyoxyethylene ether, fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene, polyoxyethylene carboxylate (such as OP10, MOA9, TX10 and three dish SPAN60 emulsifying agents).The hydrophilic radical of described anionic emulsifier is negatively charged ion, and the hydrophilic group that links to each other with hydrophobic group when it is water-soluble is negatively charged ion.Difference according to the negatively charged ion concrete structure can be divided into again carboxylic acid type, sulfuric acid type, sulfonate type and phosphate type.The hydrophilic radical of described cationic emulsifier is positively charged ion, can be divided into again quaternary amine type and amine salt type according to the difference of cationic structure concrete structure.Cationic emulsifier has the advantage of not being afraid of hard water and acid, but because it is expensive, less independent use.
