The separation layer 5 is wound in order, and an insulating jacket is provided on the outermost circumference.

用は働くと考えられる。Action Since the polymer thermosensitive resistor according to the present invention is used in a thermal environment of room temperature to 100 ° C., it is necessary to be composed of a high molecular weight additive having low volatility during heating. As the polymer matrix of the polymer thermosensitive resistor in the present invention,
A polyvinyl chloride composition plasticized with a plasticizer having a molecular weight of 500 or more selected from trimellitic acid ester, pyromellitic acid ester, pentaerythritol ester, and dipentaerythritol ester is used. This plasticizer is added in an amount of 20-60 parts by weight in 100 parts by weight of polyvinyl chloride. This polymer matrix is doped with perchlorate as an ion carrier, and the amount of this plasticizer mainly determines the mobility of the ion carrier, and greatly affects the thermistor characteristics. Perchlorate, which is corrosive to copper-based metal electrodes, is required as an ion carrier, and the ratio with the copper deactivator is important, as is the relationship between poison and drug. The amount A of the necessary ion carrier composed of perchlorate in the polymer matrix is about 1 to 10 parts by weight based on 100 parts by weight of polyvinyl chloride. The amount of the deactivating agent B works effectively when A / B = 1 to 3 in molar ratio, 120 ° C .: 300 to 600 hours, 100 ° C .: 2000 to 4000
It has been found that it exhibits an excellent anti-corrosion effect for a long time. If the amount of the triazole-based copper deactivator exceeds 3 parts by weight, bleed-out, hygroscopicity, and the like are greatly affected, resulting in inconvenience. The triazole-based copper deactivator used in the present invention is preferably a high molecular weight polymer having low volatility even in a thermal environment because the use thereof is a heat-sensitive composition. One of the most suitable for this is 3- (N-salicyloyl) amino-1,
There is 2,4-triazole. It has a high melting point of 200 ° C. or higher and a large molecular weight of 204. This copper deactivator B was added to a polymer matrix composed of 100 parts by weight of polyvinyl chloride and 45 parts by weight of dipentaerythrityl tributyrate trioctylate, and phthalic acid amic acid chlorate A (molecular weight 53
Fig. 1 shows the relationship between the rust preventive property of the polymer thermosensitive resistor dispersed together with 1), the thermistor B constant and the compounding ratio. A / B value indicates a molar ratio. When A is 5 parts by weight and B is 1 part by weight, A / B
≈2. The rust preventive property was set to the same measurement condition as in Table 1.
From FIG. 1, it can be seen that the range in which the thermistor B constant is high and the rust resistance is high is A / B = 1 to 3 and perchlorate A is about 1 to 9 parts by weight. Addition of a large amount of copper deactivator B causes bleed-out and hygroscopicity as described above, and addition of 3 parts by weight or more (A / B <1) is not preferable. The perchlorate salt used in the present invention is preferably a perchlorate salt of phthalic acid amides and imidazoles and has low molecular weight of 500 or more and low volatility. Specifically, there is a perchlorate salt with an organic cation composed of ethylene oxide adduct of phthalic acid amide, benzylimidazolium, carboxymethylimidazolium and the like. Also, metal perchlorates may be useful in some cases. Particularly, the phthalic acid amide salt is excellent in compatibility with polyvinyl chloride, and the imidazole salt is excellent in thermal stability. The copper-based metal in the present invention is referred to as copper, copper alloy, brass, etc., but a copper alloy to which a minute amount of AgSn, Al, Cd, Ni, etc. is added is mainly used. A plasticized polyvinyl chloride composition is used as the flexible polymer matrix used in the present invention. It is clear that a stabilizer that absorbs chlorine represented by tribasic lead sulfate and lead stearate vinegar has a great effect on the polyvinyl chloride composition, and the combined use thereof with the stabilizer sufficiently brings about the effect of the present invention. This is an important thing to bring out. The above plasticized polyvinyl chloride composition is obtained by adding a plasticizer for polyvinyl chloride as described above, but it is not such a method called external plasticization,
It is also obtained by using an internally plasticized polyvinyl chloride copolymer. Specific examples of this copolymer include vinyl chloride-vinyl acetate copolymer, ethylene vinyl chloride copolymer, and propylene vinyl chloride copolymer.
It is considered that the action of the present invention also works on these polymer matrices.
