Abstract

The invention discloses a gel phase-change material. The gel phase-change material is prepared from components in percentage by mass as follows: 35%-39% of sodium sulfate, 2.8%-8.5% of sodium chloride, 0.5%-2.5% of ammonium chloride, 2.5%-4% of a thickening agent, 3.0%-3.3% of borax, 0.1%-0.2% of a crystal form changing agent, 1%-1.8% of white carbon black and the balance of pure water. The gel phase-change material is adjustable at the temperature of 15-25 DEG C, is non-toxic, odorless, non-corrosive and gelatinous and has shape plasticity, the problems of supercooling, phase separation and liquid phase leakage of a traditional aqueous phase-change material are solved, furthermore, the gel phase-change material is higher in latent heat of phase change, long in cold insulation time and lowin cost, adopts a simple preparation process and can be widely applied to cold-chain transportation of products such as red wine, chocolate and the like at the storage and transportation temperatureof 15-25 DEG C.

Description

technical field [0001] The invention relates to the field of cold chain transportation, in particular to a gel phase change material, a preparation method and an application method thereof. Background technique [0002] At present, the application of cold storage technology is mostly concentrated in the fields of air conditioning and cold storage. However, with the rapid development of the national economy and the improvement of people's living standards, consumers' demand for fresh, high-quality and frozen processed food is increasing. In the process of cold chain transportation, phase change materials with appropriate temperature are needed to cool and keep the products fresh, so as to extend the shelf life of the products and reduce the loss before consumption. Due to the requirements of the biomedical industry for the transport temperature of 2-8 °C, the phase change materials with a phase transition temperature in the range of 2-8 °C have developed rapidly, while for pr...
