Abstract

<P>PROBLEM TO BE SOLVED: To provide a lightweight and inexpensive cold insulating agent, blended so that water separates and freezes on freezing and prevents the formation of the blocks of ice to freeze as a gel state, utilizing an effect of reducing heat on the re-fusion of the water with a salt content after separating/freezing, and also penetrating a very small amount of water by a negative charge effect into the gap of polymer of foamed polystyrene to be absorbed with the small pieces of the foam and not frozen. <P>SOLUTION: This cold insulating agent is obtained by mixing negatively charged water into a CMC-based cold insulating material 1, also adding small pieces 2 of foamed polystyrene, small pieces 3 of foamed polyurethane, salt 4, salad oil 5, etc., agitating to form a gel state, also mixing an aseptic agent harmless to human body and filling in a bag. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
Add styrofoam and urethane foam to CMC cold insulation material.Add salt and harmless preservatives, and mix salad oil etc. to prevent freezing of water. Separated and frozen, when water dissolves, re-fuses with salt, lowers ambient temperature, uses the effect, when the material freezes, there is a gap between the strips of thermally processed styrofoam polymer, -Water is osmotic adsorption by adding ionized water, furthermore, by mixing urethane foam pieces and salad oil, etc., preventing freezing, suppressing convection and heat conduction of cold heat, and preventing dissipation of cold heat It has an effect and can maintain the cold heat, and can reduce the weight of the refrigerant.It retains moderate hardness when freezing and freezing the refrigerant. , Which has the effect of increasing the cooling time, To.
[0002]
[Prior art]
When cooling the head or the like of a human body, an ice sac is used, or a bag containing a cooling agent is frozen and solidified in a freezer. However, if frozen, it becomes too hard and does not adapt to the head.
[0003]
[Problems to be solved by the invention]
Such a conventional bag containing a cooling agent is too hard when solidified by freezing and has a poor feeling of use. When cooling the head and body, the conventional cooling agent is initially too hard for the head. It does not fit well in the part, liquefies over time, heat convection becomes active, the divergence of cold air increases, and the cooling time is short.
[0004]
The present invention has been conceived in order to solve the problems of such a conventional bag containing a cooling agent.
[0005]
[Means for Solving the Problems]
Mix styrofoam flakes and urethane home flakes into the CMC-based cold insulation material-Add a small amount of ionized water and stir, add a preservative that is harmless to the human body, add salad oil, etc., mix salt and stir, mix with plastic Filled in a bag and used as a cooling agent, the bag containing the cooling agent is formulated so that water separates and freezes when frozen, prevents ice formation, freezes in a gel form, and separates water Utilizing the effect of freezing and lowering the surrounding heat when re-fusing with salt, a small amount of water penetrates into the gaps of the polystyrene foam due to the -ion effect, and water is absorbed by the urethane home strips. It is possible to form a light and inexpensive refrigerant that does not freeze. (CMC chemical glue, horai glue, etc. were used for experimental trial production.)
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
The cold preservative containing salt added to the CMC preservative and styrofoam flakes mixed therein is obtained by heat-treating the polystyrene foam to the CMC preservative material (1), forming a gap between the styrene polymers and (−2) water ionized. Osmotic adsorption, mixed with urethane home flakes (3) to absorb moisture, suppress fluidization, add salt (4), and freeze-frozen water re-fuses with salt when dissolved In order to use the effect of lowering the heat of the surroundings and prevent the connection freezing of water, mix salad oil etc. (5), form into a gel, use the heat insulation of plastic products, A cooling agent that is formulated to be long and filled into a bag, to be worn on the head and body.

【The invention's effect】
As is clear from the description based on the above embodiment, the bag with a cold pack of the present invention prevents the consciousness from declining due to heat when used in a place where a safety helmet is required to be worn, It is designed to prevent heat stroke, safe running such as motorcycles, and safe work such as construction and civil engineering.When using for a long time, put a spare cold storage bag in a portable cold storage container and carry it It is possible to keep a certain hardness at all times, use a bag with a cold pack, put it inside a safety helmet, put it in a bag attached to one side of a hygroscopic antibacterial deodorizing pad, and put it inside the helmet The agent can be used by attaching a pocket to one side of the moisture absorbing pad, preventing heat stroke, cooling the head in case of fever, and wearing it inside a bulletproof vest worn by police officers, or Worn by power company workers In the work clothes made of rubber, it is possible to use styrofoam and urethane foam, which are light and easy to adjust to the body when worn, and have the effect of reducing air pollution due to garbage incineration. An inexpensive cold insulator can be provided.
