As the cold-retaining agent, an aqueous solution containing a freezing agent or the like is gelled or thickened with galactomannan or the like and sealed in a synthetic resin bag or container such as polyethylene (Japanese Patent Publication No.

However, in the former case, a rigid container must be used to maintain a predetermined three-dimensional shape, and there is a problem that the product shape is restricted by the moldability of the container.

On the other hand, in the latter case, there is a problem that the aqueous solution in the porous body flows out due to the breakage of the sealing bag, which makes it unusable.

In addition, it has been proposed that an elastic foam is impregnated with a substance that turns into a gel when cooled (Act No. 45-12472).
Since the gel-like substance is liquid at room temperature, the liquid substance will flow out due to deformation of the elastic foam or the like unless it is put in a bag and sealed together with the elastic foam. Therefore, the problem that the liquid substance flows out due to the damage of the bag during use and becomes unusable still remains.

(Problems to be Solved by the Invention) Therefore, the present invention intends to provide a cold-preserving agent which can maintain a three-dimensional shape without using a rigid container and in which a liquid substance does not flow out.

(Means for Solving Problems) The present invention is based on 100 parts by weight of water and 0.03 parts of parabenzoic acid ester.
A cold insulator is obtained by impregnating a porous body with a room temperature gel substance consisting of 5 to 0.2 parts by weight, calcium hydroxide 0.1 to 0.3 parts by weight, and carboxymethylcellulose 1 to 3 parts by weight.

(Function) The gel-like substance is a jelly-like semi-solid and has no fluidity. Therefore, 100 parts by weight of water, 0.05-0.2 parts by weight of parabenzoic acid ester, 0.1-
The cold-preserving agent of the present invention obtained by impregnating a porous body with a room-temperature gel-like substance consisting of 0.3 parts by weight and 1 to 3 parts by weight of carboxymethyl cellulose is such that the room-temperature gel-like substance acting as a freezing agent flows out from the porous body even at room temperature. However, since it is held in the porous body, it can be used without being enclosed in a bag or a container.

Further, since the cold-preserving agent of the present invention holds the room temperature gel-like substance in the porous body, it is maintained in the shape of the porous body. Therefore, a free product shape can be obtained by using the porous body having a desired shape. Moreover, in the case of a porous body such as a urethane foam, it is possible to obtain a porous body having a predetermined shape very easily by foam molding or by cutting after foaming.

以下実施例によりこの発明を説明する。 The present invention will be described below with reference to examples.

(Example) A solution prepared by dissolving 0.1 part by weight of parabenzoic acid ester, 0.2 part by weight of calcium hydroxide and 2 parts by weight of carboxymethyl cellulose in 100 parts by weight of water is prepared.

Since this solution facilitates impregnation into the porous body, it is preferable that the viscosity at 25 ° C. is 500 to 1000 CPS. Then, since the blending amount is determined so as to be in the viscosity range, not limited to the above blending example, relative to 100 parts by weight of water, para-benzoic acid ester 0.05 to 0.2 parts by weight, calcium hydroxide 0.1 to 0.3 parts by weight, carboxy Methylcellulose is selected in the range of 1 to 3 parts by weight.

A predetermined amount of this solution is impregnated into a porous body made of a flexible urethane foam molded into a predetermined shape, and left as it is at room temperature for one day. During this standing, the solution in the porous body gels and a desired cooling agent is formed. Incidentally, if the standing after the solution impregnation is carried out by heating within 80 ° C, gelation can be promoted. .

(Effect) The present invention provides a cold insulator by impregnating a porous body with a room temperature gel-like substance that acts as a freezing agent. Therefore, since the room temperature gelled substance is retained in the porous body as a jelly even at room temperature, the room temperature gelled substance flows out from the porous body when it is handled at room temperature, etc., even if the cold insulating agent is not sealed with a bag or container. There is nothing to do. Further, unlike the conventional case, the solution does not flow out and cannot be used due to defective sealing of the bag, etc., and it is extremely easy to handle and has excellent durability.

Furthermore, if an elastic foam such as a soft urethane foam is used as a porous body, it can be deformed and used depending on the place of use of the cold insulating agent.
