、内部の圧力が徐々に低下する。このためブチルゴムの
ような気体透過性の低いゴム材料の使用が考えられるが
、ブチルゴムは接着加工性が悪いという欠点を有する。However, when gas permeates and diffuses through the polymer membranes that form these gas chambers, the gas sealed inside leaks out and the internal pressure gradually decreases. For this reason, it is possible to use a rubber material with low gas permeability such as butyl rubber, but butyl rubber has the disadvantage of poor adhesion processability.

出した。Next, using life jackets as an example, there are solid inflatable life jackets filled with buoyancy material such as kapok, but inflatable life jackets filled with gas to provide buoyancy are now more commonly used. @Sofms Convention (safety of 1)
Ife at 5ea) specifies that life jackets used on ships must be inflated with carbon dioxide gas, and the buoyancy loss rate of such jackets after 24 hours while floating on water must be 5% or less. It is stipulated that Charcoal gas has the property of permeating molecular membranes very well in gases, and it was extremely difficult to achieve the required quality of buoyancy reduction rate of 5% or less6. Through experiments, it was found that the present invention can achieve the object.

ある。In the present invention, it has not yet been logically investigated why the gas permeability is lowered by the addition of particles, and the effect has been clearly demonstrated even when the amount added is as small as 2 parts. What was shown came as a complete surprise to the present inventors. If it is considered that the result is simply that the flat particles overlap in a layered manner, it becomes impossible to explain the experimental result that gas permeability increases when the amount added is 40 parts by weight or more. In any case, the present invention makes it possible to provide an extremely excellent product that can save human lives, and thus greatly contributes to the development of industry.

浮力は１２．１３ｋｇであったが、２４時間後の浮力は
１０．５８ｋｇとなった。The buoyancy after being immersed in water for 24 hours was 12.29 kg (water temperature 12°C).For comparison, polyurethane rubber was calendered with only Royalsen R-390 without Sugilite mica (film thickness 0.15 m5). A life jacket of the same shape was made by processing the cloth using Welgoo. The initial buoyancy of this vest was 12.13 kg, but the buoyancy after 24 hours was 10.58 kg.

判る。Example 3 Sujirite Mica 400W (weight average particle diameter 18μ, aspect ratio 3
0) was added in an Il range of 0 to 80 parts, the resulting composition was molded using a calendar, and the tensile strength (Tb, k@f/asI'') of the resulting film was measured. However, from Figure 0, where the results shown in Figure 1 were obtained, it can be seen that the strength characteristics decrease linearly and inversely proportional to the amount of particle image added.
