The specific embodiment
Below, embodiments of the present invention are described, but this disclosed embodiment is all illustrations in all respects, should be understood to not make restriction.Scope of the present invention represents by claims, comprised and the meaning of the scope equalization of claims and all changes in scope.
[deflector roll]
First, according to Fig. 1, the deflector roll of an embodiment of the present invention is described.
Fig. 1 (a) be deflector roll of the present invention along the long side direction cutaway view of (axially), Fig. 1 (b) is lateral plan.
The roller main body 1 of deflector roll is the cylinder consisting of the first fiber-reinforced resin layer 3 and the second fiber-reinforced resin layer 4 of being located at the outside face of this first fiber-reinforced resin layer 3.The outside face of the above-mentioned roller main body 1 of deflector roll of the present invention (outside face of the second fiber-reinforced resin layer 4) is covered by diamond-like carbon film (diamond-like carbon film: be sometimes designated as below " DLC film ") 5.
As the first fiber-reinforced resin layer 3, particularly, preferably use and heat-curing resin is immersed in the fibre sheet material consisting of reinforcing fiber and the thermosetting compound of prepreg sheet material in semi-cured state.
As above-mentioned reinforcing fiber, and be not particularly limited, but can list carbon fiber, glass fibre, alumina fibre, poly-ester fibres, nylon fiber etc., and preferably use the strength-to-density ratio in these fibers, the carbon fiber of stiffness-to-density ratio excellence.As reinforcing fiber, conventionally use the fiber of diameter 5～13 μ m.
As above-mentioned fibre sheet material, can use the nonwoven fabrics, plain cloth, twill weave, satin fabric etc. of reinforcing fiber to spin cloth, in one direction the parallel fibre sheet material extending etc.
In addition, as above-mentioned heat-curing resin, use epoxy resin, unsaturated polyester resin, phenol resin etc., less this point of percent thermal shrinkage during from heatcure, is preferably used the epoxy resin in above-mentioned resin.
The thickness of every a slice with the prepreg sheet material of above structure is not specially limited, but conventionally use the prepreg sheet material of 0.1～0.3mm left and right, is comparatively desirable, more preferably, uses the prepreg sheet material of 0.1～0.2mm.
The first fiber-reinforced resin layer 3 is after above-mentioned prepreg sheet material is wound in to cylinder or core cylindraceous, by heatcure, forms.
With the axial consistent mode of the differently-oriented directivity of reinforcing fiber that contains in prepreg sheet material and the long side direction of above-mentioned core, deflector roll that wish is made reel (coiling operation cylindraceous) be comparatively desirable.Its reason is, in the differently-oriented directivity of reinforcing fiber and the consistent deflector roll of the long side direction of cylinder, as cylinder, easily produces torsion.The in the situation that of stacked multi-disc prepreg sheet material, at least containing one deck, to make the differently-oriented directivity of reinforcing fiber of this prepreg sheet material and axial inconsistent such layer of deflector roll be comparatively desirable.Therefore, in the situation that use fibre sheet material that reinforcing fiber extends along a direction, spin cloth, to change the mode of differently-oriented directivity by layer, to carry out stacked be comparatively desirable.For example,, as forming ground floor, the second layer, the 3rd layer ... prepreg sheet material, by the bearing of trend of reinforcing fiber by each layer change into long side direction (axially) with respect to roller, circumferentially, the direction that tilts of axle is comparatively desirable.More preferably, the differently-oriented directivity of reinforcing fiber and core axially (corresponding to the roller main body forming axially) intersect, in order to there is rigidity or to prevent from adopting the torsion in situation cylindraceous and to be offset predetermined angular stacked.In the situation that the prepreg sheet material that uses reinforcing fiber to extend along a direction, it is ideal being offset 90 ° the mode of quadrature (with) stacked.
The thickness of the first fiber-reinforced resin layer 3 is not specially limited, but due to the prepreg sheet material of the above-mentioned thickness of reeling in stacked mode, therefore, is generally 0.4～2mm, comparatively it is desirable to 0.5～1.5mm.Therefore, state in the use in the situation of prepreg sheet material of thickness, comparatively it is desirable to, with stacked 2～15 layers of left and right, preferably the mode of stacked 5～10 layers of left and right is reeled and used.
From the integrated viewpoint of being close to of the first fiber-reinforced resin layer 3 and the second fiber-reinforced resin layer 4, the heatcure processing that simultaneously forms the prepreg sheet material of the first fiber-reinforced resin layer 3 after the prepreg sheet material of formation the second fiber-reinforced resin layer 4 of reeling with the furnace run carrying out is comparatively desirable.
The second fiber-reinforced resin layer 4 is heat-curing resin to be immersed to the solidfied material of the prepreg sheet material forming in the fibre sheet material of reinforcing fiber extension on the long side direction (axially) of roller main body 1.
At the prepreg sheet material of the structure for the second fiber-reinforced resin layer 4, reinforcing fiber and heat-curing resin can be used the material identical with the material using in the first fiber-reinforced resin layer 3.That is, as reinforcing fiber, preferably use the carbon fiber of diameter 5～13 μ m, as heat-curing resin, preferably use epoxy resin.
Yet the prepreg sheet material using in the second fiber-reinforced resin layer 4 is different in the following areas from the prepreg sheet material using in the first fiber-reinforced resin layer 3.; in the second fiber-reinforced resin layer 4; be defined as the prepreg sheet material (hereinafter referred to as " one-way type prepreg sheet material ") of the fibre sheet material type that reinforcing fiber extends in one direction; in addition axial (long side direction of cylinder) that the differently-oriented directivity that, this one-way type prepreg sheet material is set as the reinforcing fiber that makes this prepreg sheet material is roller main body.
With the thickness of the second fiber-reinforced resin layer 4 prepreg sheet material identical with the thickness of the first fiber-reinforced resin layer 3 or the thin above-mentioned thickness of the stacked coiling of mode than the first fiber-reinforced resin layer 3, be comparatively desirable.Particularly, it is comparatively desirable reaching 0.4～1.5mm left and right, more preferably 0.5～1mm.Therefore, state in the use in the situation of prepreg sheet material of common thickness, with stacked 2～10 layers of left and right, preferably the mode of stacked 5～8 layers of left and right is reeled.
The fiber containing ratio of the second fiber-reinforced resin layer 4, because the mass area ratio of prepreg sheet material is different, but is generally 40～95 quality %, comparatively it is desirable to 50～95 quality %.
The second fiber-reinforced resin layer 4 is after the prepreg sheet material of using at first fiber-reinforced resin of having reeled, with the consistent mode of the reinforcing fiber direction of one-way type prepreg sheet material and the long side direction of core (be equivalent to roller axially) this prepreg sheet material of having reeled, then heat, by making the heat-curing resin heatcure of these prepreg sheet materials, form together with the first fiber-reinforced resin layer.
The mean roughness of the roughness of surface of the second fiber-reinforced resin layer (Ra) is that 1.0 μ m are comparatively desirable below, more preferably, below 0.8 μ m, very it is desirable to 0.7 μ m left and right.This smoothness is that effects on surface carries out polishing to be realized by after solidifying.Especially, in deflector roll of the present invention, the carbon fiber of the fibre sheet material using in the second fiber-reinforced resin layer extends on the long side direction of roller, therefore, even if the in the situation that of stacked multilayer prepreg sheet material, also can be by for regulating polishing direction and the bearing of trend of circularity to be made as necessarily.Therefore, can make the reinforcing fiber that produces because of polishing fluffing, depart from, come off, lose the small concavo-convex minimum on the second fiber-reinforced resin layer surface producing, thereby can obtain minute surface.
Deflector roll of the present invention is laminated with diamond-like carbon film (DLC film) having on the second fiber-reinforced resin layer 4 of said structure.
Diamond-like carbon film (DLC film) refers to the carbon film having with the similar high hardness of adamas, electrical insulating property, infrared ray permeability etc., it contains hydrogen slightly, be impalpable structure, and there is adamas in conjunction with (Japanese: ダ イ ヤ モ ン ド Knot closes), graphite combination (Japanese: グ ラ Off ァ イ ト Knot closes) etc.
Above-mentioned DLC film can be produced by CVD method, plasma CVD method, PVD method, ion implantation etc., but preferably by ion implantation, forms.
The thickness of DLC film 5 is not particularly limited, and it is 1～10 μ m left and right, comparatively it is desirable to 3～5 μ m left and right.
Even if the thickness of this degree, also can have abrasion test, sliding.The outside face of the second fiber-reinforced resin layer 4 can be realized higher smoothness and (comparatively it is desirable in the long side direction entire scope of roller, mean roughness (Ra) is that 1.0 μ are following), therefore, above-mentioned thickness also can be at the whole DLC film that forms of deflector roll outside face.
On the other hand, DLC film 5 is films, therefore, forms the film of the apparent condition that reflects round floor.And, because DLC film 5 is film, therefore, by DLC film 5 self is carried out to polishing, be difficult to regulate smoothness, circularity.For the above reasons, under the state before DLC film 5 forms, the abundant smoothness that improves circularity and raising real estate is significant.
In having the deflector roll of said structure, the DLC film 5 that forms the outside face of deflector roll consists of thickness 1～10 following film in μ m left and right, therefore, can meet the requirement of lightweight, abrasion test.
About this point, in existing metal thermal spraying film, need the thickness of 200 μ m left and right, in addition, even if the in the situation that of coat of metal, in order to form stable coating, also need to form coating more than 50 μ m.Yet, in DLC film, can form with the thickness of 1～10 μ m left and right the film of high hardness, excellent in wear resistance.
Above-mentioned deflector roll is as long as enter the intercalations such as bearing the two ends of roller main body 1 and insert and lead to come for axle.The manufacture method of deflector roll of the present invention is not specially limited, but can preferably be manufactured by the manufacture method of the present invention of following explanation.
(manufacture method of deflector roll)
The manufacture method of deflector roll of the present invention comprises: coiling body is heated it is solidified, take and form the operation of the fiber-reinforced resin rounding cylindrical shell that reinforcing fiber is top layer towards the fiber-reinforced resin layer of the long side direction of above-mentioned cylinder, this coiling body is to form by the second reinforcing fiber mode that the second prepreg sheet material side by side becomes the long side direction of above-mentioned cylinder with the differently-oriented directivity of this second reinforcing fiber being in one direction wound on the coiling body of the first prepreg sheet material, the differently-oriented directivity of the first reinforcing fiber and the long side direction of cylinder of this first prepreg sheet material are inconsistent, the operation that polishing is carried out in the surface of above-mentioned fiber-reinforced resin rounding cylindrical shell, and the operation that forms diamond-like carbon film on the polished surface obtaining by above-mentioned polishing process.
At coiling prepreg sheet material, produce in the operation of fiber-reinforced resin rounding cylindrical shell, use metal rounding post or the cylindric cores such as iron core, and the prepreg sheet material of reeling on this core.By using in advance cross sectional shape to be similar to just round core, the fiber-reinforced resin rounding cylinder-shaped of being produced can be become to approximate just round member by coiling.First, as long as by the first prepreg sheet material that forms the first fiber-reinforced resin layer is wound in to the coiling body that core forms the first prepreg sheet material, then, reels and form the prepreg sheet material of the second fiber-reinforced resin layer.
For axial fiber-reinforced resin layer that to produce the differently-oriented directivity of reinforcing fiber the be deflector roll fiber-reinforced resin rounding cylindrical shell as top layer, the second prepreg sheet material of at least reeling more than two circles is comparatively desirable, from enough reply circularity, regulate this point, it is comparatively desirable adopting 5～10 volume left and right.
As first and second prepreg sheet material, can use the prepreg sheet material exemplifying out in the deflector roll of the invention described above.That is, as reinforcing fiber, conventionally use the carbon fiber, glass fibre, alumina fibre, poly-ester fibres, nylon fiber of diameter 5～13 about μ m etc., as heat-curing resin, use epoxy resin, unsaturated polyester resin, phenol resin etc.
Wherein, the first prepreg sheet material is not specially limited, but uses one-way type prepreg sheet material for the second prepreg sheet material.The mode of the long side direction that the differently-oriented directivity of reinforcing fiber of take is cylinder (roller main body axially) this one-way type prepreg sheet material of reeling.
After coiling, heat, and make the resin solidification of first and second prepreg sheet material.By this, the firming body that the firming body that is formed on the first prepreg sheet material is laminated with the second prepreg sheet material on the first fiber-reinforced resin layer the second fiber-reinforced resin layer and integrated after coiling body.While extracting core after solidifying, can obtain fiber-reinforced resin rounding cylindrical shell.
Then, to the surface of the fiber-reinforced resin rounding cylindrical shell obtaining, the second fiber-reinforced resin layer carries out polishing.When making cylindric roller main body, may deviation apart from the thickness in axle center, therefore, require to approach by polishing just round.In addition, in deflector roll of the present invention, the DLC film being formed in the second fibre reinforced layer is film, easily reflects the roughness of surface as the second fiber-reinforced resin layer of bottom, therefore, needs to form concavo-convex less smooth surface.
Finishing method is not specially limited, but as shown in Figure 2, at the embedded bearing in the two ends of fiber-reinforced resin rounding cylindrical shell 10, for axle 12, inserts logical.Then, make axle 12 rotations, make fiber-reinforced resin rounding cylindrical shell 10 rotations of the first fiber-reinforced resin layer and the second fiber-reinforced resin layer, and the long side direction (axially) that polishing member 11 is outer field fiber-reinforced resin rounding cylindrical shell 10 along reinforcing fiber towards the second axial fiber-reinforced resin layer is moved, thereby carry out polishing, this is comparatively desirable.
By above-mentioned polishing, detailed reason is not clear, even if but polished in the surface part of firming body of the second prepreg sheet material duplexer that forms the second fiber-reinforced resin layer, the layer that is positioned at this surface part below is exposed in such situation, also produce hardly disengaging, the fluffing of fiber, can keep excellent smooth surface.Particularly, the mean roughness (Ra) on surface is that 1.0 μ m are comparatively desirable below, more preferably, below 0.8 μ m, very it is desirable to 0.7 μ m left and right.About this point, in contrast, at outermost layer, using to adopt the prepreg sheet material of the fibre sheet material that spins cloth type or be set as intersects in situation one-way type prepreg sheet material and the axial of roller, even if carry out polishing by identical method, also can make fibre pick or produce to depart from, to come off etc. to cause the concavo-convex change of surface of polished large because of polishing.In addition, in the conventional method, after fiber-reinforced resin layer has been carried out to polishing, also need to make by affixed epoxy resin etc. the operation of male and fomale(M&F) smoothing, but in manufacture method of the present invention, exist and can omit the such advantage of above-mentioned flow chart.
Then, form DLC film.
Formation method as DLC film, can exemplify out plasma CVD, sputtering method, ion plating etc., usings the method that forms film in the range of temperatures of fire damage as causing with pair of rollers main body 10 not.Wherein, ion implantation is desirable especially.
Ion implantation is to produce plasma by around applying high frequency voltage towards base material, more further applies high voltage pulse, to inject the method that is positioned at ion around of base material and carries out film forming.Particularly, by surrounding's formation plasma of the roller as base material (being formed with the roller of the second fiber-reinforced resin layer), and towards roller, apply negative pulse voltage, thereby from plasma sucking-off ion it is accelerated, to carry out Implantation towards the second fiber-reinforced resin layer.When the gas that contains carbon when use forms plasma, form DLC film.
As the plasma raw material using, use carbon compound.As carbon compound, can use the saturated hydrocarbons such as methane, ethane, propane, butane, the unsaturated hydrocarbons such as ethene, propylene, butadidenne, the aromatic hydrocarbonses such as benzene, toluene.By by above-mentioned hydrocarbon species acts raw material, in DLC film, contain hydrogen.Hydrogen amount in DLC film depends on method for making, membrance casting condition.As plasma forming method, be not particularly limited, can exemplify out the method for high-frequency discharge, microwave discharge, heated filament electric discharge.
Use the film forming of Implantation to have mixolimnion at the interface formation of the second fiber-reinforced resin layer and film, therefore, existence can form the such feature of film of close property excellence.In addition, compare with CVD method, plasma CVD method etc., ion implantation exists and can be filmed at low temperatures, and can form the feature such with the fine and close film of CVD method same degree with clinging force substrate with higher.
In addition, before DLC film forms, as pre-processing, also the second fiber-reinforced resin layer can be exposed in gas for pre-processing, plasmas such as fluoro-gas, hydrogen-containing gas, oxygen-containing gas.Also can carry out repeatedly pre-processing.
The thickness of DLC film forms 1～10 μ m left and right, comparatively it is desirable to, and forms 3～5 μ m.Even if the thickness of this degree, also can be met as the desired condition of deflector roll by original the had abrasion test of DLC film, sliding properties.
In addition, as mentioned above, average surface roughness (Ra) as the polished surface of the second fiber-reinforced resin layer of bottom is below 1.0 μ m, comparatively it is desirable to below 0.8 μ m, more preferably about 0.7 μ m, therefore,, even if the DLC film of the thickness of this degree, the reinforcing fiber in the second fiber-reinforced resin layer of bottom also can not rupture and expose together with resin.
In addition, method of the present invention is after the polishing of the second fiber-reinforced resin layer carrying out in order to ensure circularity, without the affixed resin in order further to make male and fomale(M&F) smoothing, also without carrying out bottom layer treatment as plating, carry out polishing etc. as metal thermal spraying film after abrasion test film forming, therefore, compared with prior art flow chart number can be reduced, and the raising of capacity rating can be realized.
Embodiment
(1) experimental example
As the prepreg sheet material of the constituent material of the first fiber-reinforced resin layer, the second fiber-reinforced resin layer, use epoxy resin is immersed to the prepreg sheet material making in fibre sheet material that carbon fiber (diameter 5～7 μ m) extends along a direction.The thickness of every a slice prepreg material is 0.1～0.17mm.
Above-mentioned prepreg sheet material is wound in to the irony pipe of external diameter 57mm in the mode of the axioversion with respect to above-mentioned iron pipe, and back and forth to form the mode of eight layers, reels.Then, the differently-oriented directivity of carbon fiber is being adjusted to the axial of above-mentioned iron pipe, and is reeling six times (six layers) afterwards, with 120 ℃, resin is being heated and it is solidified.After solidifying, extract pipe, can obtain fiber-reinforced resin rounding cylindrical shell.
As shown in Figure 2, at the two ends of fiber-reinforced resin rounding cylindrical shell 10, bearing is installed, and is inserted logical for axle 12.Make axle 12 towards direction of arrow rotation on one side, Yi Bian make polishing member 11 along moving axially, thus polishing has been carried out in the second fiber-reinforced resin layer surface.
Use the control surface roughness integrator E35A of Tokyo Seimitsu Co., Ltd to measure the roughness of surface after polishing, mean roughness (Ra) is 0.7.
By ion implantation, on this polished surface, form DLC film.The thickness of formed DLC film is 3～5 μ m.Like this, produce the deflector roll that is formed with DLC film (mean thickness is 4 μ m) at the outside face of the cylinder being formed by the first fiber-reinforced resin layer (about 0.85mm), the second fiber-reinforced resin layer (thickness 0.65mm).
Utilize the surface after electron microscope observation DLC film forms.Electron micrograph has been shown in Fig. 3.In Fig. 3, the known white line as reinforcing fiber extends in one direction.
(2) comparative example
The prepreg sheet material of the prepreg sheet material identical type of using in use and embodiment.
On iron pipe, as the first fiber-reinforced resin layer, to form the mode of eight layers, reeled after prepreg sheet material, the mode of the differently-oriented directivity quadrature of fortified resin is stacked gradually at ground floor and the second layer, reeled six layers, using as the second fiber-reinforced resin layer.
After resin is heating and curing, under the condition identical with embodiment, the second fiber-reinforced resin layer has been carried out to polishing.Identical with embodiment, by ion implantation, on this polished surface, formed DLC film.Like this, produce the deflector roll that is formed with DLC film (mean thickness is 4 μ m) at the outside face of the cylinder being formed by the first fiber-reinforced resin layer (about 0.85mm), the second fiber-reinforced resin layer (thickness 0.65mm).
Utilize the surface after electron microscope observation DLC film forms.Electron micrograph has been shown in Fig. 4.In Fig. 4, infer and have the part of intersecting with white line as reinforcing fiber, but or confirm the projection of DLC film because of fluffing.
The result of the roughness of surface of the DLC film that uses the control surface roughness integrator E35A of Tokyo Seimitsu Co., Ltd to determine the part photographing in microphotograph has been shown in Fig. 5.As projection, in observed part, confirming to become the protuberance of height 213.7 μ m.This can think that a part for the reinforcing fiber of the second fiber-reinforced resin layer is cut off together with resin and the reason of fluffing.
Therefore, in using the deflector roll of the fiber-reinforced resin the layer orientation of carbon fiber is not made as to specific direction, in order to realize the DLC film that smoothness is higher, need be after DLC film form, then the processing of carrying out DLC film surface is processed.
Industrial utilizability
Deflector roll of the present invention lightweight, and abrasion test, sliding properties are excellent, therefore, can be used as the various carrying rollers such as plastic sheet, sheet material made of paper, ceramic green sheet.
In addition, according to the manufacture method of deflector roll of the present invention, without the bottom layer treatment of plating, make the such operation of male and fomale(M&F) smoothing after polishing, compared with existing method, can reduce flow chart number, the capacity rating of deflector roll is excellent.
