A kind of anti-caking agent of ice crystal cooling pad phase change material

Abstract

The invention discloses an anti-caking agent for an ice crystal cooling pad phase-change material as well as a preparation method and an application thereof. The anti-caking agent comprises the following components by mass percent: 1-25 percent of sodium hexametaphosphate solution, 5-60 percent of complexing agent, 2-50 percent of surfactant and the balance of water; and according to the preparation method, the sodium hexametaphosphate solution, the complexing agent and the surfactant are added into water of 50-55 DEG C and mixed for 30 minutes at 50-55 DEG C to form a homogenous clear stable solution, and therefore the anti-caking agent for an ice crystal cooling pad phase-change material is obtained. The addition amount of the anti-caking agent is 0.5-15wt% of the ice crystal cooling pad phase-change material during application.

Description

technical field [0001] The invention belongs to the fields of inorganic chemistry and analytical chemistry, and in particular relates to an anti-caking agent for phase-change materials of ice crystal cooling pads. Background technique [0002] Phase-change energy storage materials are substances with certain functions. This type of material can release energy when changing from liquid to solid, and when changing from solid to liquid, it needs to absorb energy from the environment, and the temperature during the entire phase change process Little has changed. Its phase change process is only related to temperature, and this type of material has a very wide application value in heat storage and temperature control. Among many phase change energy storage materials, compared with other types of phase change materials, inorganic hydrated salt phase change energy storage materials have high phase change latent heat per unit mass, good thermal conductivity, non-toxicity, good chem...

AI Technical Summary

Problems solved by technology

[0005] However, the ice crystal cooling pad phase change material often has a lot of agglomeration problems in the process of repeated melting and crystallization. Because the agglomeration is relatively hard and large, it brings great inconvenience to people's use and also affects the use of the ice crystal cooling pad. life

It is also because of the agglomeration phenomenon that the ice crystal cooling pads that have been exported are often returned, and the merchants will suffer economic losses because of this.

[0006] At present, there are no patents and related reports on the anti-caking agent of phase change materials for ice crystal cooling pads
