Abstract
A liquid accumulating heat and cold for daily use, so-called 'cold-heat liquid', which is developed based on the properties of high molecular colloid material. The liquid could quickly absorb heat, and release slowly heat at normal temperature, and keep a high temperature at normal temperature; on the other hand, could release heat at a low temperature, absorb slowly heat at normal temperature, and keep a low temperature at normal temperature. The product is made of natural high molecular material, could decompose naturally after disposal, and is nontoxic and harmless for human. The preparation method comprises, solving natural high molecular material, such as carrageeenen,chitosan and so on, into an aqueous solution or an acidic solution, adding some amount of small molecular substance, such as alcohol, glycol, mixing uniformly and obtaining the 'cold-heat liquid'.
Description
Technical field the present invention relates to a kind of daily " cold-storage, accumulation of heat " liquid, is called for short " cold and hot liquid ".This liquid is heat absorption fast at high temperature, and slowly heat release at normal temperatures can keep comparatively high temps at normal temperatures for a long time then; Equally, release of heat reaches low temperature at low temperatures, and slowly heat absorption at normal temperatures can keep low temperature at normal temperatures for a long time then; And this liquid does not have the phenomenon of freezing at subzero 7 degrees centigrade.This product is made by natural macromolecular material, and discarded back natural degradation is nontoxic to human body, and can not produce pollution to environment, belongs to the environmental protection series products.
Background technology this product be utilize the polymer colloid material exclusive good " accumulation of heat, cold-storage " performance develop.Existing domestic this series products, as " heat is precious " etc., mostly with after can not be caused environmental pollution easily by natural decomposition; Be curdled appearance at normal temperatures, can not be out of shape, feel is relatively poor; And can only heating in water bath, can not use microwave heating, use inconvenient.
Summary of the invention adds a certain amount of small-molecule substance then with being made into certain density colloid in water-soluble solution of natural polymer or the acid solution, as versicolor pigment, ethanol, propyl alcohol, ethylene glycol, glycerol etc., mixes, and promptly gets " cold and hot liquid "; Get final product in the plastics bag of different shape, the size of packing into then, the container.Used macromolecular material comprises: carrageenin, chitosan, carboxymethyl chitosan, agar-agar, carboxymethyl cellulose, algin, hyaluronic acid.Available wherein a kind of, also available wherein several mixed solution.Concentration range from 5/1000ths to percent 30.When " accumulation of heat ", with sack that liquid is housed with microwave heating to certain temperature or put into boiling water constant temperature, take out then and can do accumulation of heat and use; When " cold-storage ", sack is put into refrigerator-freezer be chilled to required low temperature and take out again and can make cold-storage and use.
Embodiment takes by weighing the chitosan powder of 10 grams and puts into 1 liter container, the acetic acid or the hydrochloric acid soln that add 500 milliliters 1 mole dissolve it fully, add 20 milliliter of 90% ethanol and an amount of pigment (according to the color of required liquid) then and mix and get final product.
Embodiment takes by weighing 10 gram carrageenins, carboxymethyl chitosan, agar-agar, carboxymethyl cellulose, algin, hyaluronic acid respectively and puts into container, add 1 liter of boiling water, mix, add 20 milliliter of 95% ethanol, 20 milliliters of glycerol and an amount of pigment (according to the color of required liquid) then and mix and get final product.
Claims (3)
1. a method for preparing environment-friendly type " cold and hot liquid " comprises being made into certain density colloid in water-soluble solution of natural polymer raw material or the acid solution, adds a certain amount of small-molecule substance then, mixes.
2. used macromolecular material comprises: carrageenin, chitosan, carboxymethyl chitosan, agar-agar, carboxymethyl cellulose, algin, hyaluronic acid, available wherein a kind of or wherein several.Mass percent concentration scope from 5/1000ths to percent 30.
3. used small-molecule substance comprises: ethanol, propyl alcohol, ethylene glycol, glycerol, available wherein a kind of or wherein several.The mass percent concentration scope from one of percentage to 40 percent.
