Problems solved by technology

[0004] First of all, when the thickness of the Du material plate is less than 0.5mm, and the thickness of the Dx material plate is less than 1.0mm, the plate is thin and deformed when the copper powder layer is sintered, resulting in difficult processing technology and unstable bonding strength of the surface anti-friction layer; secondly, due to the sintered copper powder layer The powder layer is non-dense, especially when making flanging bushes, the product is scrapped due to wrinkling and cracking of the copper powder layer on the surface of the flanging bend; finally, the waste of the copper powder layer on the surface is large, and the manufacturing cost of the whole process is relatively high

Embodiment Construction

[0040] see figure 1 , The three-layer composite self-lubricating sheet of this embodiment is based on the SPCC cold-rolled steel plate as the substrate 3, the copper alloy layer 2 as the middle layer, and the friction-reducing and wear-resistant spraying layer 1 as the surface layer. The copper alloy layer 2 can be copper alloy with high wear resistance such as tin bronze or brass, such as CuSn5Pb5Zn5, HPb59-1, H62 and the like.

[0041] In the present embodiment, the three-layer composite self-lubricating plate, the composition of the friction-reducing and wear-resistant spraying layer 1 is as follows in mass percentage:

[0042] Molybdenum disulfide 5-25%, graphite 5-15%, alumina powder 0-1.0%, polytetrafluoroethylene powder 0-10%, curing agent 1-10%, toughening agent 1-5%, and the balance is epoxy resin;

[0043] The curing agent is an aliphatic amine curing agent, or an imidazole latent curing agent;

[0044] The toughening agent is polyamide resin or nitrile rubber res...

Abstract

The invention discloses a three-layer composite self-lubricating plate and a manufacture method of the three-layer composite self-lubricating plate. The three-layer composite self-lubricating plate is characterized in that the plate uses a cold-rolled steel plate as a base body, a copper alloy layer as a middle layer and an antifriction wear-resisting coating as a surface layer. Particularly, when a flanged lining is manufactured, the product discarding caused by winkled peel generation and cracking of a copper layer at the flange bending part is avoided. During the thin plate manufacture, the processing is simple, the bonding strength is high, and the performance is stable. Compared with the existing three-layer composite self-lubricating material, the three-layer composite self-lubricating plate has the advantage that the cost is reduced by 20 to 40 percent.

Description

technical field [0001] The invention relates to a self-lubricating material and a manufacturing method thereof, in particular to a three-layer composite self-lubricating plate and a manufacturing method thereof. Background technique [0002] At present, the known three-layer composite self-lubricating material has a three-layer composite material of modified polytetrafluoroethylene-copper alloy-steel back (hereinafter referred to as Du material); a three-layer composite material of modified polyoxymethylene-copper alloy-steel back ( hereinafter referred to as Dx material); however, during the production process of Du material and Dx material, 60-200 mesh spherical copper powder is sintered on the surface of the steel plate to form a rough surface layer with certain gaps on the surface to increase the bonding strength with the anti-friction layer , because the above two surface composite anti-friction materials completely rely on the copper powder layer as a transitional bond...
