[0046] (Preparation of wire coating materials)

[0047] As shown in Tables 1 to 3, the components such as polyvinyl chloride, plasticizer (component A), chlorinated polyethylene (component B), MBS resin (component C), and lead-free stabilizers are listed in Tables 1 to 3. The indicated mixing amount (parts by mass) was mixed using a uniaxial extruder at 180°C, and formed into pellets using a granulator to prepare a polyvinyl chloride composition.

Abstract

Provided are a wire coating material, insulated wire, and a wire harness that can be reduced in diameter, can be inserted in a terminal without buckling when used as an insulated wire, and has satisfactory flexibility and excellent wire outer appearance. A wire coating material comprising 100 mass parts of polyvinyl chloride, 10-20 mass parts of a plasticizer, 1-6 mass parts of chlorinated polyethylene, and 1-6 mass parts of an MBS-based resin, the total amount of the chlorinated polyethylene and the MBS-based resin being 2-7 mass parts, is used to coat a conductor (1) so that the thickness of an insulating body (2) is no greater than 0.25 mm; and an insulated wire having a wire outer diameter of less than 1.1 mm is obtained.

Description

Technical field [0001] The present invention relates to a wire coating material, an insulated wire, and a wire harness. More specifically, it relates to a wire coating material suitable for use as a coating material of an insulated wire used in wiring of automobiles, equipment, etc., an insulated wire using the coating material, and Wiring harness. Background technique [0002] Conventionally, as an insulator of a low-voltage electric wire for automobiles, a polyvinyl chloride resin composition is generally used from the viewpoint of excellent flame retardancy and chemical resistance. In recent years, in addition to the need to effectively utilize the limited space of automobiles, the requirements for thinning the insulators of electric wires and reducing the diameter of electric wires have further increased. [0003] When the outer diameter of the wire is reduced, there is a problem that the wire is buckled when the terminal is inserted into the connector and the terminal is diff...
