Embodiment Construction

[0018] 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.

[0019] like figure 1 As shown, a copper powder used on a copper-lead composite material is a mixture of QSn6Zn6Pb3 copper powder and graphite copper powder in a mass ratio of 7:3.

[0020] QSn6Zn6Pb3 copper powder, its chemical composition is: Sn 5% ~ 7%, Zn 5% ~ 7%, Pb 2% ~ 4%, the balance is Cu.

[0021] Graphite copper powder contains 30% graphite, 10% zinc stearate and 60% lead-free bronze powder.

[0022] A kind of production method of the copper powder used on copper-lead composite material, it comprises the steps:

[0023] A. Sampling: Take out 7 parts of QSn6Zn6Pb3 copper powder and 3 parts of graphite copper powder;

[0024] B. Dehumidification: Use a heating vessel to heat the QSn6Zn6Pb3 copper powder to 80°C and stir it continuous...

Abstract

The invention discloses copper powder used on copper and lead composite material and a production method of the copper powder. QSn6Zn6Pb3 copper powder and graphite copper powder are mutually fused in a proportion by weight of 7: 3, the QSn6Zn6Pb3 copper powder comprises the following chemical components: 5%-7% of Sn, 5%-7% of Zn, 2%-4% of Pb and the balance of Cu, and the graphite copper powder contains 30% of graphite, 10% of zinc stearate and 60% of lead-free bronze powder. The production method of the copper powder used on the copper and lead composite material comprises the following steps: A, sampling; B, dehumidification; C, fusion; D, screening, and impurity removal; dehumidification does not need to be carried out on the graphite copper powder, but the graphite copper powder has to be stored in the environment with the room temperature is lower than 14 DEG C. The production method has the advantages of simple technology, convenient operation and good product abrasion resistance.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to copper powder for copper-lead composite materials and a production method thereof. Background technique [0002] Copper-lead composite material is a self-lubricating composite material made by rolling copper powder and steel plate after mutual sintering. It is usually a bearing alloy with high hardness and elastic modulus, but in actual use, the wear resistance is not enough. Meet the needs. Contents of the invention [0003] The object of the present invention is to provide a copper powder used on copper-lead composite materials with stable performance and good wear resistance to solve the above problems. [0004] Another object of the present invention is to provide a method for producing copper powder used on a copper-lead composite material with simple process, convenient operation and improved wear resistance. [0005] The technical problem to be solved by t...
