Abstract
The invention discloses a phase-change material with the phase-change temperature of minus 15 DEG C. The phase-change material comprises the following components in percentage by weight: 5-25 percent of ammonium chloride, 2.5-25 percent of crylic acid, 5-15 percent of alum, 5-25 percent of maleic anhydride, 5-10 percent of carboxymethyl cellulose sodium, 5-25 percent of oil and the balance of water. Due to the mode, the phase-change material with the phase-change temperature of minus 15 DEG C is large in latent heat of phase change, stable in performance, reversible in phase change process, wide in raw material source, low in cost, safe and reliable, has no phase separation phenomenon after being used for a long time and can be circularly used for more than ten thousand times; the consumption of electric energy is reduced; the positive effects of saving energy and reducing emission are achieved; and the phase-change material can be popularized and applied in refrigerating and freezing processes in food stuff, medicines and the like.
Description
Technical field
The present invention relates to the phase change material field, particularly relate to a kind of transformation temperature and be-15 ℃ phase change material.
Background technology
The energy is the material that energy transformation is provided to nature, is the basic substance of mankind's activity, can be divided into conventional energy resources and novel energy to the energy according to the type of service people.Conventional energy resources is comparative maturity technically; use commonplace; but the continuous development along with human society; people to the demand of the energy in quick growth; the world oil crisis that occurs of twentieth century particularly; make energy problem be subjected to people's common concern, therefore energy-conservationly become a problem that urgency is to be solved.Phase change material is as energy accumulator, in fields such as energy-conservation, temperature controls significant meaning arranged.
Phase change material refers to vary with temperature and changes the material that physical properties also can provide latent heat, and the process that changes physical properties is called phase transition process, and at this moment phase change material will absorb or discharge a large amount of latent heat.In cold chain transportation process such as food and medicine, phase change material can make food and medicine be in the low temperature environment, solves the fluctuation of accumulating temperature in the transportation, effectively controls the quality of product.But present existing phase change material latent heat of phase change is little, unstable properties, and result of use is bad.
