Abstract

The invention discloses a cool pillow and manufacturing method. The content of the cool pillow comprises the following components: 15-60% of urea, 10-30% of phosphate, 5-15% of guar gum and 25-70% of drinking water, wherein the guar gum is cation-type or anion-type guar gum, the concentration of the urea is 33-50% and the phosphate is disodium hydrogen phosphate and sodium dihydrogen phosphate. The cool pillow is manufactured through the following steps in sequence: firstly dissolving alkaline refrigerants, i.e. the urea and the disodium hydrogen phosphate in drinking water, wherein the solution is alkaline; then adding the guar gum into the solution and stirring uniformly; when high molecular colloidal sol is formed, adding the acidic refrigerant sodium dihydrogen phosphate into the mixture, mixing uniformly to obtain the content; and finally packaging the content into a packaging bag, thereby obtaining the cool pillow. The normal use time of the cool pillow is longer than that of a common cool pillow. The phosphate in the formula is dissolved at the temperature of 27 DEG C so as to absorb heat, so that the cool pillow can be maintained in a low temperature state for a longer period of time before reaching 30-DEG C .

Description

technical field [0001] The patent of the present invention relates to a cooling pillow and a manufacturing method thereof, in particular to a cooling pillow combined with a refrigerant and a cold storage agent and a manufacturing method thereof. Background technique [0002] The theoretical basis of this invention patent is based on "cool head, warm feet, and fullness" (source " The Book of Changes: Tai Gua ), the main advantages of the patent of the present invention are: comfortable use, long duration and low cost. [0003] At present, the phase transition temperature of cooling pillows on the market is too low, and the maintenance time is short, which leads to overcooling when in contact. For example, the ordinary cooling pillows on the market now only use water as the cooling medium, and the low maintenance time after cold treatment is short, which cannot meet the long-term cooling requirements at night. Time cooldown required. Chinese patent CN102462288A discloses a c...
