Description
Technical field
The present invention relates to energy storage material fields, more specifically to a kind of 8 ~ 10 DEG C of composite phase change energy-storing cool storage materials
And preparation method thereof.
Background technique
With China's Energy restructuring, renewable energy ratio is risen year by year, and integrated energy system and service become hair
Exhibition trend is coordinated further promote efficiency of energy utilization with the cascade utilization of the energy by multipotency.In this respect, energy storage technology
Technical support is provided for the conversion of a variety of clean energy resourcies.Wherein phase change cold-storage material can be applied to Solar use, Heating,Ventilating and Air Conditioning system
System and process industrial etc..For phase transition temperature within the scope of 8 ~ 10 DEG C, in combination with water cold storage and ice-storage system, energy conservation drop
This, is obviously improved the refrigerating efficiency of refrigeration machine.But compare existing cool storage material, often exist cold storage capacity it is low, layering and not
Can crystal counter the problems such as, Chinese patent CN10760182A and CN108251068 China using sodium carboxymethylcellulose as ten water
The thickener of sodium sulphate system, it may appear that phase transition temperature hysteresis effect is larger, and corruption is degradable；And Chinese patent
The disodium hydrogen phosphate dodecahydrate of CN103059816A patent, sal glauberi, washing soda system system, preparation use poly- third
Olefin(e) acid sodium is as thickener.
