The purpose deposited and discharge, have that thermal storage density is big, store exothermic process approximation isothermal, process easy to control, and can be repeated several times
The advantages such as use.
Paraffin is that a kind of hydro carbons extracted from some distillation of oil, shale oil or other Colophonium mineral oil mixes
Compound, main component is solid alkane, odorless, tasteless, for white or faint yellow translucent solid.Paraffin is noncrystal, but has
Significantly crystal structure.Typically usually using inexpensive technical grade paraffin is the most hydrocarbon as insulation material, technical grade paraffin
The mixture of compound, does not has fixing fusing point, only one of which fusion temperature scope.Paraffin has the most excellent as a kind of PCM
Point, as high in latent heat of phase change, almost without surfusion, fusing time steam pressure is low, be not susceptible to chemical reaction and chemically stable
Property preferably, spontaneous nucleation, be not separated and corrosivity, price is relatively low;But it also has the shortcoming that some are important, such as heat conduction
Coefficient is low and density is little, be susceptible to solid-liquid phase change etc..Directly use paraffin to make phase-change material and can bring inconvenience.
Micro encapsulation refers to solid particle, drop or the bubble small with coated film or shell material spreading.In recent years,
Microcapsule technology is widely used in microorganism, animal and plant cells, enzyme and other various bioactivators and chemicals
Immobilization aspect.Microencapsulated phase change material is exactly NEW TYPE OF COMPOSITE phase transformation material microcapsule technology being applied to phase-change material and being formed
Material.
Patent CN101671149A discloses a kind of paraffin microencapsulated phase-change thermal-storage mortar and preparation method thereof, with
The inorganic gel materials such as cement are matrix, mix the organic phase change material paraffin of micro encapsulation, are formed and have the new of heat accumulation function
Type external wall outer insulation material；Use coupling agent process for modifying surface and polymer fiber toughening technology, improve paraffin microcapsule
The compatibility with inorganic gel materials.But, microcapsule prepared by the method selects carbamide and formaldehyde as cyst material, is giving birth to
Easily bring pollution during one-tenth process and use, be also unfavorable for environmental protection and safety.It addition, select to add coupling agent to improve paraffin
Microcapsule and the compatibility of inorganic gel materials, its effect is the most obvious.
Resin rubber powder is the modifying agent such as a kind of novel product rubber, resin, high molecular polymer, levigate rubber powder,
Or employing carries out mild oxidation processing to Colophonium, so that the improved asphalt mixture of the performance of Colophonium..
