Embodiment 1～8

[0058] Each component was mixed so that the compounding composition shown in Table 1 was obtained, and the rubber composition for insulating layers containing a non-crosslinked silicone rubber was prepared. Next, using an extrusion molding machine, the conductor (cross-sectional area of ​​0.5mm 2 ) was extruded with a rubber composition for covering an insulating layer with a thickness of 0.2 mm (180° C.×5 minutes). Next, the coating layer was heat-treated under the conditions of 200° C.×4 hours, thereby completing the crosslinking of the silicone rubber of the coating layer. Thus, the insulated electric wires of Examples 1-8 were obtained.

Abstract

The present invention provides an insulated electric wire excellent in abrasion resistance and gasoline resistance, which has an insulating layer containing cross-linked silicone rubber. In this insulated wire, the periphery of the conductor is covered with an insulating layer containing cross-linked silicone rubber, wherein the molecular weight between cross-linking points of the cross-linked silicone rubber is 2,000 or less. The Shore A hardness of the insulating layer measured in accordance with JIS K6253 is preferably 50 or more. The insulating layer may further contain calcium carbonate powder, magnesium oxide powder, magnesium hydroxide powder, and the like.

Description

technical field [0001] The present invention relates to an insulated electric wire, and more specifically, relates to an insulated electric wire suitable for use in vehicles such as automobiles. Background technique [0002] As insulating materials used for insulated electric wires of vehicles such as automobiles, halogen-containing materials such as compounds containing vinyl chloride resins and halogen-based flame retardants can be used. Insulation materials containing halogens sometimes produce corrosive gases when incinerated and discarded. Therefore, attempts have been made to use insulating materials that do not contain halogens from the viewpoint of environmental protection and the like. [0003] For example, Patent Document 1 describes the use of a non-halogen insulating material obtained by mixing aluminum hydroxide with uncrosslinked silicone rubber as an insulating material for insulated wires. [0004] prior art literature [0005] patent documents [0006] P...
