Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0022] Such as figure 1 As shown, the production process of the steel-based copper-plastic composite material includes the following steps:

[0023] 1) Cutting: cut out the steel plate 1 and copper mesh 2 according to the specified size;

[0024] 2) Copper plating: Copper plating is performed on the surface of the steel plate 1;

[0025] 3) Sintering and cooling: spread the copper mesh 2 on the steel plate 1, put them together into a mesh belt sintering furnace with protective gas, and combine them together. The sintering temperature is 950°C, and the sintering time is 45-60 minutes After sintering, the temperature is lowered through a cooling jacket of a certain length, and it is released from the furnace at 100°C;

[0026] 4) Composite poly...

Abstract

The invention discloses a production technique for steel-base copper-plastic compound material. The production technique comprises the following steps of 1 blanking, 2 copper plating, 3 sintering and cooling, 4 colloid synthesis with compound teflon, 5 finish rolling, 6 stoving and cooling, 7 pressure sintering and 8 cooling. The protective gas is nitrogen-hydrogen mixed gas. When pressure sintering is conducted, the heating temperature ranges from 370 to 380 DEG C, and the pressure ranges from 40.0 to 50.0 MPa. The production technique for the steel-base copper-plastic compound material has the advantages that the quality and the stability of product are improved, and the combined strength is high.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a production process of steel-based copper-plastic composite materials. Background technique [0002] Steel-based copper-plastic composite materials, mainly steel plate as the matrix, high-temperature sintered copper powder on the steel plate, after the copper powder is sintered and cooled, a layer of polytetrafluoroethylene is compounded on the copper powder to form a powder, and then low-temperature sintered. But in use, the shaft sleeve made of this composite material has small torque, short life and uneven wall thickness; Contents of the invention [0003] The object of the present invention is to provide a production process of steel-based copper-plastic composite material in view of the above problems, which has a simple process flow, strong wear resistance of the produced product, and can prolong the service life of the material. [0004] The technical probl...
