Embodiment 1
[0033] Embodiment 1: see figure 1 , a nano ice pack, the ice pack is mainly composed of 10-20 parts of nano airgel powder, 1-3 parts of plant thickener, 1-5 parts of emulsifier, 5-10 parts of balance agent and 60-70 parts of water . Nano-airgel powder can be made into aerogel, which is light, does not occupy volume, has high latent heat value, and has good slow-release effect;
[0034] As a rheology regulator, plant thickeners can increase the viscosity of the system, keep the system in a uniform and stable suspension state or emulsified state, or form a gel. Most of the natural plant thickeners are made from plants and seaweeds containing polysaccharides and viscous substances. They have no pungent smell and are natural and environmentally friendly.
[0035] The emulsifier adjusts the consistency; when it is dispersed on the surface of the dispersant, it forms a thin film to charge the dispersed phase, which prevents the small droplets of the dispersed phase from coagulatin...

Abstract
The invention discloses a nanometer ice bag and a preparation method thereof. The ice bag is mainly prepared from 10 to 20 parts of nanometer aerogel powder, 1 to 3 parts of plant thickening agents, 1to 5 parts of emulsifying agents, 5 to 10 parts of balancing agents and 60 to 70 parts of water. The method comprises the following steps of a, adding water into the nanometer aerogel powder and theplant thickening agents; performing mixing and stirring to form a gel body; b, proportionally adding the emulsifying agents for thickening; c, adding balance medicine agents for debugging; d, preparing the materials into an aerogel body; e, performing supercritical drying; f, performing pressing shaping. Compared with the prior art, the prepared aerogel powder particle aerogel has light weight andbelongs to lightest solid; no volume is occupied; the processing is easy; the potential heat value is as high as 210 to 330 j/kg; the ventilation performance is good; the temperature slow release effect is good; the heat insulation and cold storage time is long.
Description
technical field [0001] The invention relates to an ice pack, in particular to a nano ice pack and a preparation method thereof. Background technique [0002] Ice packs are an upgraded replacement product for ice cubes, which have more applicability, are convenient to use, hygienic, and have a wide range of uses. It is used for medical high fever cooling, antipyretic, anti-inflammatory and analgesic, cold compress beauty, sprain, hemostasis, suppuration, skin care and other auxiliary physical therapy. Refrigerated transportation of various biological frozen reagents, long-distance refrigerated transportation of solder paste, poultry medicine, pharmaceuticals, plasma, vaccines, aquatic products, poultry, ornamental fish and foreign trade fresh food. It has high requirements on air permeability, weight, heat retention and cold retention capacity. Most of the existing ice packs are water-absorbing resin or CMC products, and the effect is not ideal. Contents of the invention ...
