Abstract

The invention provides a nanometer anion cold storage agent, which is characterized in that the formula is prepared from the following ingredients in parts by mass: 100 parts of deionized water, 10 to20 parts of ammonium chloride, 2 to 5 parts of nanometer tourmaline, 5 to 8 parts of sodium hydroxyethyl cellulose and 2 to 5 parts of tri-glycine sulfate. According to a preparation method, the ammonium chloride and the nanometer tourmaline are sequentially added into deionized water; the materials are uniformly stirred; after the heating is performed to 70 to 80 DEG C, sodium hydroxyethyl cellulose and tri-glycine sulfate are added; the continuous stirring is performed for 3 to 4 hours at the stirring speed of 6000 to 8000 rpm. The cold storage agent has the general cold storage effect; meanwhile, the anion generation effect can be achieved; the contact with transportation products is avoided; the nanometer anion cold storage agent is favorable for the long-distance cold chain transportation and fresh keeping of vegetables, fruits, seafood products and the like.

Description

technical field [0001] The invention belongs to the technical field of materials and relates to a nano negative ion cold storage agent. Background technique [0002] With the improvement of people's living standards, the demand for long-distance transportation of fresh fruits and vegetables, meat, seafood and other products continues to grow. Low temperature phase change cool storage agent is the core technology of cold storage transportation, and low temperature phase change cool storage agent is usually sealed in the interlayer of the transport box to keep cold. During the long-term transportation process, even in a low-temperature environment, problems such as bacterial growth are still inevitable and cause product deterioration. Negative ions in the air have deodorizing, antibacterial, and fresh-keeping functions. Increasing the concentration of negative ions in the air in the transport box is conducive to longer-term freshness preservation. There is no report on the c...
