The invention discloses the phase change material that a kind of transformation temperature is-15 DEG C, comprise the composition of following weight percents: ammonium chloride 5%-25%, vinylformic acid 2.5%-25%, alum 5%-15%, maleic anhydride 5%-25%, sodium cellulose glycolate 5%-10%, grease 5%-25%, water surplus.By the way, a kind of transformation temperature provided by the invention is the phase change material of-15 DEG C, and latent heat of phase change is large, stable performance, long-time use is without phenomenon of phase separation, and phase transition process is reversible, can be recycled more than ten thousand times, raw material sources are extensive, cost is low, safe and reliable, decreases expending of electric energy, reach the positively effect of energy-saving and emission-reduction, can apply in the refrigerations such as food and medicine, refrigerating process.
Description
Technical field
The present invention relates to phase change material field, particularly relate to the phase change material that a kind of transformation temperature is-15 DEG C.
Background technology
The energy is the material providing energy transformation to nature, is the basic substance of mankind's activity, according to type of service people, the energy can be divided into conventional energy resources and novel energy.Conventional energy resources is comparative maturity technically; use commonplace; but along with the development of human society; people to the demand of the energy in quick growth; the particularly world oil crisis of twentieth century appearance; make energy problem receive the common concern of people, therefore energy-conservationly become a problem anxious to be resolved.Phase change material, as energy accumulator, has great meaning in fields such as energy-conservation, temperature controls.
Phase change material refers to and varies with temperature and change the material that physical properties also can provide latent heat, and the process changing 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 the cold chain transportation process such as food and medicine, phase change material can make food and medicine be in low temperature environment, solves the fluctuation of accumulating temperature in transportation, effectively controls the quality of product.But present existing phase change material latent heat of phase change is little, and unstable properties, result of use is bad.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the phase change material that a kind of transformation temperature is-15 DEG C, and latent heat of phase change is large, stable performance.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of transformation temperature to be the phase change material of-15 DEG C, comprise the composition of following weight percents:
