The advantageous effect of the embodiment of the present invention includes：By the way that additive is added in phase-changing energy storage material, solve existing
Phase-changing energy storage material easily there is the technical issues of phenomenon of phase separation, considerably improve the stable circulation of phase-changing energy storage material
Property.
Specific implementation mode
It in order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below will be in the embodiment of the present invention
Technical solution be clearly and completely described.The person that is not specified actual conditions in embodiment, builds according to normal condition or manufacturer
The condition of view carries out.Reagents or instruments used without specified manufacturer is the conventional production that can be obtained by commercially available purchase
Product.
The phase-change heat-storage material and preparation method thereof of the present invention is specifically described below.
A kind of phase-changing energy storage material, percentage, including energy storage material of main part 70%-95%, thickener
The additive of 0.01%-10%, nucleating agent 0.1%-10%, reinforcing material 1%-5% and 3%-5%, the additive packet
Include propylene glycol and vaseline, the mass ratio of the propylene glycol and vaseline is 2-3：1.6-1.8.
Wherein vaseline is called petroleum ester, as vaseline, its primary raw material is to pass through normal pressure and vacuum distillation from crude oil
The slack wax deviate from the residual oil left afterwards.
The reason of problem of cyclical stability difference, which occurs, in phase-changing energy storage material is, after a number of uses, energy storage material of main part
After multiple energy storage cycle, phenomena such as reunion, this is because repeatedly energy storage material of main part is stored up in phase transformation after energy storage cycle
Can disperse in material it is uneven caused by, and such case can be improved using lubricant by having been generally acknowledged that, but conventional lubrication
Agent can become extremely sticky after being mixed with thickener, cause energy storage material of main part to be not easy to disperse, can reduce stable circulation instead
Property.
Meanwhile the mobility of lubricant is larger, after being applied in phase-change heat-storage material, can increase the mistake of phase-change heat-storage material
Cold phenomenon, these drawbacks result in conventionally, are unsuitable for that lubricant is added in phase-changing energy storage material.
It, can be with it has been found that by the compounding of partial lubrication agent, while the rationally ratio of adjustment lubricant and thickener
Above-mentioned drawback is avoided, and improves phenomenon of phase separation, and then reaches the technical purpose for improving cyclical stability.Wherein, apply for human hair
Existing propylene glycol and vaseline not only all have preferable lubricating action, during preparing phase-changing energy storage material, preferably using it
Lubricant effect, energy storage material of main part can preferably be disperseed, be avoided during recycling, energy storage material of main part occur
Agglomeration, and then lead to the problem of cyclical stability difference.Simultaneously as propylene glycol and vaseline belong to Organic Alcohol or esters object
Matter, for the mobility of its own compared with thickener, difference, can be significant when propylene glycol and vaseline compound not counting too big
Improve phase-change heat-storage material phenomenon of phase separation, meanwhile, surfusion compared to be not added with by propylene glycol and vaseline compounding add
Before adding agent, no significant difference.
Brought forward is stated, and the relative scale of thickener and additive is particularly important, and thickener is excessive, can reduce the lubrication of lubricant
The effect for improving cyclical stability is not achieved in effect, and additive is excessive, and the mobility for being bound to cause phase-changing energy storage material is crossed greatly
The generation of acute surfusion.
It has been found that in phase-changing energy storage material, the mass percent control of thickener is in 0.01%-10%, addition
The mass percent control of agent exists:0.1%-5%, while the proportional region that should control additive and thickener is 1：1-2.
Meanwhile in additive propylene glycol and vaseline ratio, for control additive overall flow rate it is most important, application
People has found that the mass ratio control of propylene glycol and vaseline is 2-3：The overall flow rate of 1.6-1.8, additive are relatively mild, with thickening
After agent mixing, the probability of phenomenon of phase separation can not only be reduced, while the aggravation of surfusion will not be caused.
More preferably, phase-change heat-storage material, percentage, including energy storage material of main part 80%-95%, thickening
The additive of agent 0.01%-7.5%, nucleating agent 0.1%-10%, reinforcing material 1%-5% and 0.1%-5%.By reasonable
The accounting of thickener is reduced, the accounting of energy storage material of main part is improved, the energy storage density of phase-changing energy storage material can be improved, meanwhile,
Thickener accounting is reduced, release flow further increases the circulation ability of phase-changing energy storage material.
