Embodiment
In order to understand the utility model further, below in conjunction with embodiment, the utility model preferred embodiment is described, but should be appreciated that these describe just for further illustrating feature and advantage of the present utility model, instead of the restriction to the utility model claim.
The utility model embodiment discloses a kind of metal base image-fixing film, and Fig. 1 is the structural representation of a kind of metal base image-fixing film embodiment of the utility model, as shown in Figure 1, comprising: metal-based layer 1; Be covered in the layer of silica gel 2 on described metal-based layer surface and special teflon rete 3 successively.
Metal-based layer 1 is the key factor affecting metal base image-fixing film.The metal-based layer 1 that the utility model adopts is preferably stainless-steel tube, chromium pipe or nickel pipe.Metal-based layer 1 is metallic cylindrical body, that is, the looped cylindrical be made of metal.The thickness of metal-based layer 1 is preferably 0.04mm ~ 0.08mm, is more preferably 0.05mm ~ 0.07mm.
The metallic cylindrical body that metal-based layer 1 preferably adopts strip job operation to prepare, blank is the metallic cylinder blank that can carry out plastic working, and metal cylinder blank rotates about the axis to be processed into.
Described metal base image-fixing film also comprises the layer of silica gel 2 and special teflon rete 3 that are covered in described metal-based layer surface successively.Preferably, the silica gel that preparation layer of silica gel 2 uses is mixed with metallic silicon power, improves the heat conductivility of silica gel.The particle mean size of described metallic silicon power is preferably 5 ~ 30 μm, is more preferably 10 ~ 20 μm.The thickness of layer of silica gel 2 is preferably 0.08 ~ 0.30mm, is more preferably 0.1 ~ 0.2mm.
The thickness of special teflon rete 3 be affect this metal base image-fixing film properties key factor, the thickness of special teflon rete 3 is preferably 0.01mm ~ 0.10mm, is more preferably 0.03mm ~ 0.08mm, is more preferably 0.04mm ~ 0.06mm.
Metal base image-fixing film described in the utility model is prepared by the following method, comprises the following steps:
Step a: stainless-steel tube is inserted in axle core, in order to be convenient in demoulding, uniform one deck release agent sprayed by axle core;
