（産業上の利用分野）
本発明は、耐熱性、耐油性、耐寒性に優れた絶縁電線に
関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an insulated wire with excellent heat resistance, oil resistance, and cold resistance.
（従来の技術と問題点） 従来よりシリコーンゴム絶縁電線は、電気特性。(Conventional technology and problems) Traditionally, silicone rubber insulated wire has excellent electrical properties.
耐熱性が良いことから機器内配線等の耐熱性が要求され

素樹脂。Because of its good heat resistance, it has been used in many places where heat resistance is required, such as in wiring inside equipment. However, silicone rubber has insufficient resistance to certain oils and solvents, which limits its use in areas where it may come into contact with, for example, solin or hydrocarbon solvents. Until now, 7-no-resin has been used in places where oil resistance, solvent resistance and heat resistance are required.

。(Structure and operation of the invention) That is, in the heat-resistant insulated wire of the present invention, an insulating layer made of a composition in which silicone rubber and fluororubber are mixed in a range of 80:20 to 30 (weight ratio) is formed on a conductor. and cross-linked. This ML paraboloid improves the oil resistance while maintaining the heat resistance and cold resistance of silicone rubber, and when the amount of fluororubber used is small, the oil resistance and solvent resistance are low (the conventional problem cannot be solved). Furthermore, if too much fluororubber is used, the cold resistance will be greatly reduced, the characteristics of silicone rubber will be lost, and at the same time it will become expensive.

Crosslinking was achieved by heating for a minute. In addition, the filler in the composition shown in Table 1 is a silicic acid filler, and the crosslinking aid and crosslinking agent are 11J for each system as shown in the notes.

である。(Effect of the invention) As shown in these test results, Examples 1 and 2 in which silicone rubber was mixed with hynylidene hepta-67 fluorinated propylene fluororubber, and ethylene 47-propylene fluorinated rubber were mixed with silicone rubber. All of the mixed Example 3 are heat-resistant insulated wires that are cheaper than fluororubber insulated wires that have improved oil resistance and solvent resistance without losing the excellent cold resistance of silicone rubber.

悪くなると同時に高価である。On the other hand, the silicone rubber insulated wire of Comparative Example 1 has poor oil resistance, and Comparative Example 2, which has a large proportion of fluororubber, has poor cold resistance and is also expensive.

安価で実用的価値の高い絶縁電線である。As mentioned above, the heat-resistant insulated wire of the present invention is inexpensive and has practical value, without compromising the advantages of the conventional heat-resistant insulated wire having an insulating layer made of 7/7 resin, fluororubber, or silicone rubber, and compensating for the drawbacks. It is a highly insulated wire.
