【 摘 要 】

By the design of molecular structure, improved polyurethane was synthesized and the material exhibited excellent mechanic properties, electrical insulation, resistance to chemical corrosion and UV aging. Its tensile and flexural strength were 58.4 MPa and 101.2 MPa; surface and volume resistivity were 9.68 × 1015 and 2.60 × 1016.cm, respectively; and their loss modulus was less than 13% exposed under serious chemical substance and UV irradiation. Moreover, the properties of the polyurethane were superior to traditional epoxy and unsaturated polyester resin. Herin, resulted composite material poles and cross arms were operation under demonstration line, and accumulated relevant operating parameters.
