Water-swelling treatment liquid of polymer material and swelling treatment method using the same

摘要

The present invention relates to an aqueous swelling treatment liquid for swelling a polymer material and a swelling treatment method of a polymer material using the swelling treatment liquid. The swelling treatment liquid is composed of a swelling agent and water, And a swelling agent which is added in such a manner that a swelling agent exceeding the saturation amount is present in a free state is used as the swelling agent. This swelling agent is introduced into a treatment tank, and the polymer material to be treated is immersed while stirring continuously, It is possible to effectively swell the polymer material while keeping the polymer material in a sealed container together with the storage solution in an appropriate container after the treatment. In addition, since water is used as the carrier, it is not only costly but also has no environmental pollution and is harmless to the human body.
