Title:
【発明の名称】自己温度調節発熱体及びそれを用いたフレキシブル面状発熱体
Document Type and Number:
Japanese Patent JP2719946
Kind Code:
B2
Abstract:
Super high polymeric polyethylene glycol whose molecular weight is 100,000 to 1,000,000 or a mixture of the same and polyethylene glycol whose molecular weight is 600 to 10,000 is dissolvedly mixed with carbon powder or mixed with it in the presence of a solvent so that the carbon powder is uniformly dispersed therein, and thus, a plane heater compound which is flexible at the normal temperature can be obtained. This compound is formed into a self-temperature control heater which can have a required switching temperature within a range of 5 to 60 DEG C mainly by varying a mixing ratio of polyethylene glycol having a molecular weight of 600 to 10,000. Such a plane heater can be applied for various purposes requiring low-temperature heating, such as preventing freezing or melting snow, and also high-temperature heating, such as heating/air conditioning.
