持つものも作り得る。(Prior art and problems to be solved) As a heat-resistant insulated wire, a cross-linked heat-resistant insulated wire in which a covering layer made of polyethylene or ethylene-α-olefin copolymer is provided on a conductor and the covering layer is cross-linked is often used. Are known. These polyolefin-based crosslinked heat-resistant insulated wires can withstand high temperatures by using a hindered phenol-based antioxidant alone or a combination of a hindered phenol-based antioxidant and a sulfur-containing antioxidant. It is possible to provide high resistance to thermal deterioration at 150°C, and it is possible to make products that have a lifespan of 20,000 hours or more at 150°C.

度まで熱変形を抑えることが必要になってきている。However, since the melting point of these resins is 150°C or lower, their thermal deformability depends on the shape retention of the three-dimensional network structure formed by crosslinking, and the thermal deformability at temperatures of 150°C or higher is usually It was quite large. For example, when used in the engine room of a recent high-performance automobile, the operating environment temperature may temporarily exceed 150°C, causing the coating layer to deform significantly. It has become necessary to suppress deformation.

いて好適な電線被覆材料である。In order to improve the thermal deformability of wires, a resin with a melting point of 200° C. or higher may be used, but there are not many resins with a melting point of 200° C. or higher that have the flexibility to be used as a covering material for electric wires. Among these, polyester elastomers that have aromatic polyester such as polybutylene terephthalate as a hard segment and aliphatic polyol alone or both aliphatic polyol and aliphatic polyester as soft segments have relatively good heat resistance and a low melting point. 200～
Some have a temperature range of 220°C and have the flexibility necessary as a wire coating material. Furthermore, by including a polyfunctional crosslinking aid, crosslinking by ionizing radiation becomes possible, and sufficient shape retention can be imparted even at temperatures above 200°C, making it suitable for use in fields where the operating temperature is 150°C or above. It is a suitable wire coating material.

めた。The ratio of hard segments to soft segments is in the range of 80: 2G - 80: 4G by weight; if the amount of hard segments increases more than this, the heat aging resistance will decrease significantly, and if the amount of soft segments increases, the melting point will decrease. As the temperature drops below 200''C, handling becomes difficult due to the adhesiveness of the resin.The melting point was determined by differential thermal analysis.
