For this reason, since the wires are constantly subjected to stress due to the damage, the wires using the above-mentioned engineering plastics as an insulator could not be put to practical use except in extremely limited cases.

However, since this polysulfone also has poor solvent resistance, the resulting blend composition has poor solvent resistance, and there is a problem in using it in a state where it is bent or the like.

う溶剤である。In order to achieve thinner electric wires, the inventors have developed a thermoplastic resin having two or more aryl groups in its structural unit, which is attracting attention as an insulator for medium-sized and small-diameter insulated electric wires in engineering plastics. We conducted intensive studies to improve its solvent resistance. As a result, it was surprisingly confirmed that cracking and crazing resistance against dioctyl phthalate and oil can be significantly improved by incorporating an appropriate amount of an inorganic filler consisting of particles of a specific size. Dioctyl phthalate is added as a plasticizer for vinyl chloride resin, and contact and migration is expected when it is installed alongside a vinyl chloride resin-coated electric wire. Also, oil is a solvent that may be encountered in any environment.
従って、これらに対し優れた改善効果が得られたことは
、電線の絶縁体としての使用を可能にすることを意味す
るということができる。Therefore, it can be said that the fact that excellent improvement effects have been obtained in these areas means that it becomes possible to use the material as an insulator for electric wires.

ラック性が向上することを確認できた。On the other hand, from among the resins mentioned above, we focused on a mixture of polyetherimide and polysulfone, which has a large improvement effect on elongation as described above, and conducted a similar study on its resistance to solvent stress cracking, which is an unresolved issue. It was also confirmed that solvent stress cracking properties were significantly improved simply by mixing an appropriate amount of an inorganic filler consisting of particles of a specific size into the resin.

げることかできるが、これらに限定するものではない。In the present invention, the inorganic filler that has been found to be effective in preventing solvent stress cracking has an average particle size of 0.5 μm or less. If it is larger than this, excessive stress concentration will occur in the filler itself, and the effect of improving solvent stress cracks may be lost. Regarding the blending amount, if it is less than 0.05 parts by weight, it will not be effective against solvent stress cracking.
If it exceeds 10 parts by weight, the elongation when used as an insulator will be greatly reduced. As the inorganic filler, so-called non-oriented fillers whose shape is close to spherical or granular are preferable.From this point of view, carbon black, silicon dioxide, titanium dioxide, wet zinc oxide, barium sulfate, colloidal calcium carbonate, heavy Examples include, but are not limited to, calcium carbonate and magnesium oxide.

かし、これは推論の域であり、詳細についてはなお不明
である。Possible mechanisms of action of such inorganic fillers are as follows. In other words, at the interface between the inorganic filler particles and the resin in the stressed resin composition, many peelings or minute cavities occur in the direction perpendicular to the stress, and the fracture energy is released before large cracks such as crazing or cracks occur. This is thought to be to dissipate the However, this is still in the realm of speculation, and the details are still unclear.

同様に優れた結果を示している。Examples 1 to 3 are examples in which polyetherimide was used as the resin and a predetermined amount of silicon dioxide having an average particle diameter defined by the present invention was blended, and no crazes or cracks were observed and the elongation was large. Examples 4 and 5 are examples in which polysulfone was used as the resin and titanium dioxide within the range specified by the present invention was used as the inorganic filler, and no cracks or clay damage were observed here either. Examples 6 and 7 in which polyarylate was used as the resin and carbon black was used as the inorganic filler also showed excellent results.

業上の意義は大きなものがある。[Effects of the Invention] As explained above, according to the present invention, by using so-called engineering plastics, even if the coating of the insulated wire is made thinner, there is no risk of deterioration of mechanical strength such as wear resistance. This greatly improved solvent resistance makes it possible to obtain thin-walled, small-diameter insulated wires with excellent properties, and its industrial significance is that it can appropriately respond to the miniaturization and weight reduction of today's equipment. There's something big.
