Abstract

The invention discloses a preparation method of nickel plated glass fibers and magnetic conductive rubber prepared by the nickel plated glass fibers, belongs to the technical field of conductive rubber preparation, and solves the problem that existing metal conductive filling materials has high density and high cost and can not meet the development of modern electronic industry. A certain amount of glass fibers are added into a hot alkali solution, a roughing solution, a sensitization solution, and an activating solution respectively for preplating treatment; then the glass fibers are added into a nickel plating solution to obtain nickel plated glass fibers with excellent conductivity; the obtained nickel plated glass fibers are added into a silicone rubber matrix; and magnetic conductiverubber is obtained through a traditional rubber preparation method. The conductive rubber prepared by the method of the invention has volume resistivity which is reduced to a lowest value of 0.04 omega.cm, remanent magnetization of 0.1-0.5 emu/g, and coercivity of 80-100 Oe.

Description
