Abstract

The invention discloses a three-layer composite self-lubricating material and a continuous production process thereof. The three-layer composite self-lubricating material comprises a metal base platelayer, a ball powder layer and a PEEK modified material layer located on the ball powder layer, wherein the ball powder layer is sintered on the base plate, and the PEEK modified material layer is compounded on the surface of the ball powder layer through hot rolling. According to the invention, plastic particles are subjected to softening melting treatment through an extruder, the extruded membrane sheet is combined with a heated ball powder coiled tape, and then synchronous compounding is performed through a hot rolling mill, so that the problem that the heating plate is polluted in the plastic melting process can be effectively solved; and the material is directly compounded by a hot roller, so that the use of a release agent can be prevented, and the problem of plastic surface smoothness can be effectively solved.

Description

technical field [0001] The invention relates to a composite material processing technology, which is a specific three-layer composite self-lubricating material and its continuous production technology. Background technique [0002] The production process of the traditional three-layer composite self-lubricating material is generally three kinds. One is to sinter low-carbon steel plate and spherical bronze powder to form a spherical powder plate, and then place PEEK modified powder on the spherical bronze powder layer, and melt the plastic by heating. Finally, it is rolled into a three-layer composite plate through a rolling mill; the second one also needs to sinter the spherical powder plate first, and then cover a layer of modified polyether ether ketone film on the spherical bronze powder layer, and make the contact surface mutual in a molten state by hot pressing. The third is to cover the modified PEEK plastic particles on the spherical bronze powder layer of the ball po...
