得ることができる。Further, since the melamine resin-based sponge can be formed into an arbitrary shape or cut and used, the sponge is formed in a tray shape or a box shape or the like so as to be suitable for a product using a cold insulator. It is also possible to use
As a result, a very efficient and cool effect without waste can be obtained.

This product is a melamine resin sponge (40 mm × 40 mm × 7 mm) having a dense open cell and a bulk specific gravity of about 9 kg / m 3.
0 mm) were prepared, impregnated with water in a water tank, taken out of the water tank, and allowed to stand in a freezer in a freezer without dripping water.

ダンボール箱を、２４時間、室内に放置しても、生鮮食
料品は、安定して、冷蔵状態に保たれた。The sponge thus frozen was put in a transparent polyethylene bag, placed around the packaged fresh food, and stored in a thick waterproof cardboard box. Even if this cardboard box was left indoors for 24 hours, the fresh food product was kept stably and refrigerated.
【００１２】また、静置した状態では、解凍されても、
スポンジの保水性が高いため、水が過剰に分離すること

常の保冷材より効率のよい保冷効果を発揮する物となっ
た。[0012] In addition, in the state where it is allowed to stand still,
Since the water retention of the sponge is high, the sponge exerts a heat insulating effect in a water-containing state without excessive separation of water, and exhibits a more effective cooling effect than ordinary cooling materials.

央凹部に、アイスクリームを入れ、包装した。In another example, the center of a melamine resin-based sponge having a bulk density of about 9 kg / m 3 having dense open cells is hollowed out to have a thickness of 20 mm at the bottom and 20 to 30 mm at the periphery. The container was impregnated with water and frozen, and ice cream was placed in the central recess and packaged.

る。The water retention material of the present invention can be used repeatedly as many times as the sponge is repeatedly impregnated with water, frozen and thawed. In addition, after use, it is useful as a cleaning material in an appropriately moistened or dry state, and can be used to remove stains on dishes and gas ranges without using a detergent. . Furthermore, since the sponge itself has a heat insulating effect, it is possible to maintain the effect as a cold insulator for a long time. In addition, since the melamine resin sponge can be formed into an arbitrary shape or cut and used, it can be used in a form suitable for a product using a cold insulator.
