Description
Technical field
The present invention relates to a kind of emulsion for the preparation of phase-change accumulation energy film, specifically a kind of compound method of phase-change accumulation energy emulsion liquid and application thereof.
Background technology
Phase-changing energy storage material be absorbing environmental in the process itself undergone phase transition heat or when needed to Environment release heat, reach and control and regulate ambient temperature and energy-conservation object.As under shining upon, phase change material absorbs the heat of the sun in a large number, produces material phase transformation, and when ambient temperatures are low, phase change material discharges its heat stored, and makes envrionment temperature keep stable within a certain period of time.Phase change material passes through phase-change accumulation energy, heat release, thus the object reaching heat preservation energy-saving.Therefore phase-changing energy storage material obtains application in a lot.As city UTILIZATION OF VESIDUAL HEAT IN, electrical network peak load shifting utilizes, and buildings constant temperature is heat insulation, domestic heating insulation etc.
Phase-changing energy storage material can divide organic by its chemical constitution, inorganic, organic-inorganic mixing material.Organic phase change energy storage material is as paraffin, thermal conductivity is lower, heat transfer property is poor, thus reduce the usefulness of system, combined phase-change energy storage material has advantage adjustable within the specific limits, but it is easily aging, energy storage effect is just lost after circulation several times, it is wide that Inorganic phase change energy storage material has use range, thermal conductivity is large, storage density is large, phase variable volume is little, toxicity is little, the advantages such as low price, firmly get people's favor, wherein inorganic salt hydrate is a most important class in low temperature phase change heat accumulating, but there will be cold, be separated, affect it to widely use, solution is a lot, as added nucleator, thickening material, make microcapsule, make nano-functional material.
Although Inorganic phase change energy storage material is at city waste heat, electrical network peak load shifting, the heat insulation aspect of building thermostatic has wide application prospects, and application is agriculturally also little.Current green house of vegetables and agricultural film cover, especially winter occur suddenly serious cold wave cold freeze or cold spell in later spring time, many green house of vegetables and soil all will cover thick grass quilt, once have little time to cover, farm crop will by freeze injury, agricultural will be subject to large loss, how phase-changing energy storage material can be used green house of vegetables and mulch film is the problem that contriver will solve.The first solves green house of vegetables scorching not by burning sun, avoids burning sun peak; It two is coldly freeze weather when cold wave arrives or produces suddenly, makes vegetable or flower unlikely therefore freezing.
Summary of the invention
object of the present invention, is Inorganic phase change energy storage material to be applied in agriculturally, is namely applied on green house of vegetables or flower shed, is used on mulch film.The first solves green house of vegetables scorching not by burning sun, avoids burning sun peak; Its two be when cold wave arrive or produce suddenly cold freeze weather time, make vegetable or flower unlikely therefore freezing.The present invention is the object for reaching one, namely solves green house of vegetables scorching not by burning sun, avoids burning sun peak, also save air conditioner energy simultaneously.
