This elastic body is obtained by adding glass powder of a specific composition to a water-soluble silicate (water glass) aqueous solution and allowing it to react for a long time. This inorganic elastic body is attracting attention because its elasticity and other properties change depending on the amount of water present.

The proportion of the oxide glass of component B is 1 to 100 parts by weight, preferably 10 to 70 parts by weight. When the amount of oxide glass is less than 1 part by weight, the hardness of the obtained elastic body decreases, and when the amount of oxide glass exceeds 100 parts by weight, the detachment of the oxide glass tends to increase.

It is. If it is less than 100 parts by weight, it will be difficult to blend. If it exceeds 500 parts by weight, the elastic modulus of the obtained elastic body tends to decrease. The properties of the elastic composition of the present invention vary greatly depending on the amount of water and/or water-soluble alcohol added. Therefore,
It may be blended with water and/or water-soluble alcohol in any proportion to obtain the desired performance.
In this respect, the blending amount is not particularly limited. For example, when obtaining an extremely flexible jelly-like product,
The amount of water and/or water-soluble alcohol added is based on a total of 100 parts by weight of polyvinyl alcohol or its modified product as component A and oxide glass as component B.
More than 500 parts by weight may be used.

Therefore, the reaction time is shorter than that of conventional inorganic systems, and production efficiency is increased. Of course, when obtaining an elastic body with unique performance, such as a jelly-like material when collapsed, the above reaction conditions are not restricted.

使用することができる。(Effects of the Invention) In the elastic composition of the present invention, water and/or water-soluble alcohol molecules are bonded to a matrix formed by component A, polyvinyl alcohol or a modified product thereof, and component B, oxide glass, or between the matrices. It is believed that it is present in molecularly dispersed form. Therefore, the presence of water and/or water-soluble alcohol appears to significantly contribute to the elasticity of the resulting composition.
In fact, the elasticity decreases as the water and/or water-soluble alcohol content decreases. Also, as the content of water and/or water-soluble alcohol increases,
The elasticity increases, but if it exceeds a certain amount, the fluidity increases and the elasticity decreases. If the amount of water and/or water-soluble alcohol in component C is 1 to 5 times the total weight of component A, polyvinyl alcohol or its modified product, and component B, oxide glass, the elasticity is conventional inorganic type. It is more expensive than , and its uses are greatly expanded. If it collapses, it can be used as core material for golf balls. On the other hand, those with high fluidity and low elasticity can be used for things such as mochi that can change shape.

る。 The elastic composition of the present invention has a much more relaxed pH than the elastomer composition using water glass disclosed in Japanese Patent Publication No. 53-45199, and is easier to handle. The composition of the above-mentioned publication has a pH of about 11 and must be handled with care, but the composition of the present invention has a pH of about 8 to 9, which is within the range that can be easily handled.
