Abstract
A fluoric three-layer composite material is prepared through spreading a layer of spherical copper particles on the surface of a steel plate, sintering, leveling, spreading a teflon sheet on the surface of sintered copper particle layer, and roller pressing at least one time to squeeze part of teflon into the gaps between adjacent two copper particles.
Description
Technical field
The present invention relates to the manufacture method of composite, relate in particular to a kind of manufacture method of using the laminated composite plate of steel-copper-polytetrafluoroethylmaterial material.
Background technology
Metal material, macromolecular material and ceramic material all have its strong point and deficiency on serviceability, the range of application of oneself is respectively arranged.Along with science and technology development, more and more higher to the requirement of material, it is very difficult to use single material to satisfy multiple requirement.Therefore, composite has appearred, at present, the general laminated composite plate of the steel-copper of Shi Yonging-polytetrafluoroethylmaterial material, they are used as the blank of sliding bearing in large quantities.Its technology is: the wet-milling sintering of polytetrafluoroethylene (PTFE) anti-attrition particle and emulsifying agent mediation is spread on surface of steel plate shop spherical copper powder sintering-smoothing-surface, and making tetrafluoroethene and sintering that copper powder surperficial be arranged, good bond-smoothing is rolled onto specific thickness becomes blank.Twice sintering of such arts demand, and the existence of moisture content in second time wet-milling sintering because in the emulsifying agent, moisture content wherein can be retained between copper powder layer and the polytetrafluoroethylene (PTFE), seriously influence both adhesions, cause polytetrafluoroethylene (PTFE) to separate with steel plate under the effect of load, the quality of composite can not guarantee.
Summary of the invention
The object of the present invention is to provide that a kind of technology is simple, energy resource consumption is few, the manufacture method of the adhered F 3-layer composite material of reliable in quality, long service life.
In order to achieve the above object, the manufacture method of adhered F 3-layer composite material is: lay the spherical copper powder sintering at surface of steel plate, make two layers of composite board-smoothing, it is characterized in that having the surface of spherical copper powder to spread ptfe sheet at sintering, through at least roll-in the part polytetrafluoroethylene (PTFE) in the ptfe sheet is expressed in the space of spherical copper powder, makes ptfe sheet and two layers of composite board be bonded into 3-layer composite material.
Make adhered F 3-layer composite material according to the method described above, lack once sintered than original technology, and moisture content can not occur and be retained between copper powder layer and the polytetrafluoroethylene (PTFE), guaranteed product quality, reduced manufacturing cost, and the thickness 0.01-0.03 of original polytetrafluoroethylene (PTFE) can be increased to the 0.08-0.12 millimeter, prolonged the service life of composite greatly.
Description of drawings
Fig. 1 is the structural representation of two layers of composite board;
Fig. 2 is the structural representation of 3-layer composite material.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
The manufacture method of adhered F 3-layer composite material is successively:
1, lays spherical copper powder 2 according to the conventional method sintering on steel plate 1 surface, make two layers of composite board as shown in Figure 1;
2, on levelling machine that two layers of composite board smoothing are whole;
3, sintering has the surface of spherical copper powder to spread ptfe sheet 3 on two layers of composite board;
4, roll-in is expressed in the space of spherical copper powder 2 on two layers of composite board the part polytetrafluoroethylene (PTFE) in the ptfe sheet 3 through secondary, make ptfe sheet 3 and two layers of composite board be bonded into 3-layer composite material as shown in Figure 2, and make 3-layer composite material be rolled down to the flatness and the thickness of regulation, be added with lubricating oil at roller surface during roll-in.
Claims (3)
1, the manufacture method of adhered F 3-layer composite material, lay the spherical copper powder sintering at surface of steel plate, make two layers of composite board one smoothing, it is characterized in that having the surface of spherical copper powder to spread ptfe sheet at sintering, through at least roll-in the part polytetrafluoroethylene (PTFE) in the ptfe sheet is expressed in the space of spherical copper powder, makes ptfe sheet and two layers of composite board be bonded into 3-layer composite material.
2, the manufacture method of adhered F 3-layer composite material according to claim 1 is characterized in that described roll-in is to be added with lubricant at roller surface.
3, the manufacture method of adhered F 3-layer composite material according to claim 2 is characterized in that described lubricant is meant lubricating oil.
