Abstract

The invention discloses a cold chain coolant that is characterized by being prepared from, by mass, 5%-10% of metal chloride, 1%-4% of ammonium chloride, 1%-3% of alcohol, 0.1%-0.3% of active silicon,2%-5% of borax, 0.3%-1% of docusate sodium, 5%-10% of amino-terminated polyethylene glycol amidated pectic acid, 2%-4% of aleuritic acid group organic salt and the balance water, wherein the aleuritic acid group organic salt is prepared by carrying out ion exchange reaction on aleuritic acid and choline. The invention further discloses a preparation method of the cold chain coolant. The cold chain coolant disclosed by the invention has the advantages of large latent heat, small supercooling degree, good heat transfer, good cold chain effect, small toxicity and pollution, high cold chain efficiency and long cold storage time.

Description

technical field [0001] The invention relates to the technical field of logistics refrigeration, in particular to a cold chain cold storage agent and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the remarkable progress of science and technology, the cold chain logistics industry has developed rapidly, providing people with safe and fast services. This logistics technology generally refers to the production, storage, transportation, and sales of refrigerated and frozen foods. It is a systematic project to ensure the quality of food and reduce food consumption in all links before consumption.
