Abstract

The invention discloses a high-efficiency low-temperature phase-change cold storage agent and a preparation method thereof, relates to the technical field of agricultural insecticides, and aims to solve the problems of large phase-change latent heat, supercooling phenomenon and phase separation phenomenon of the existing phase-change cold storage agent. The low-temperature phase change cold storage agent comprises super absorbent resin, a composite energy storage agent and purified water, the super absorbent resin comprises hemicellulose alkali liquor, acrylic acid and styrenesulfonic acid, and the composite energy storage agent comprises multiple of sodium acetate, ethyl lactate, pentaerythritol, glycerol, sodium benzoate, glycine, lysine, sorbitol, glucose and proline.

Description

technical field [0001] The invention relates to the technical field of cold storage agent preparation, in particular to a high-efficiency low-temperature phase-change cold storage agent and a preparation method thereof. Background technique [0002] At present, there are a large number of products in the society that are transported and sold without cold chain protection. According to statistics, the serious loss rate of deterioration and decay is as high as 20%. Applied in the field of product storage, transportation and preservation, it can not only prolong the product storage period and improve the quality, meet the consumption needs of consumers, but also reduce the waste of products in the process of storage and transportation, and increase economic benefits. [0003] At present, the phase change cool storage agent is mainly solid-liquid phase change material, among which the inorganic phase change cool storage agent of hydrated salt accounts for the majority, its phase...
