Detailed description of the invention
Fig. 1 is the sectional view of fixing roller in one embodiment of the invention.
Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.Many details are explained in the following description in order to fully understand this hair
It is bright.But the invention can be embodied in many other ways as described herein, those skilled in the art can be not
Similar improvement is done in the case where violating intension of the present invention, therefore the present invention is not limited by the specific embodiments disclosed below.
Unless otherwise defined, all technical and scientific terms used herein and belong to technical field of the invention
The normally understood meaning of technical staff is identical.Term as used herein in the specification of the present invention is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term " and or " used herein includes one or more phases
Any and all combinations of the listed item of pass.
Referring to Fig. 1, a kind of preparation method of fixing roller is provided in one embodiment of the invention comprising following steps:
S1, on the outer peripheral surface of substrate roller 100 fluororesin-coated material to form priming coat on the substrate roller 100
110。
Wherein, substrate roller 100 is the basic skeleton structure of fixing roller, can select fixing metal roller or heat-resist
Resin fixing roller.Further, when selecting fixing metal roller, the preferably good aluminium alloy roller of thermal conductivity.Of course it is to be understood that
Other materials as metal tube can also be with, such as iron, nickel and their alloy, stainless steel etc..Further, when selection resin
When fixing roller, the preferred good polyimides roller of heat curing type.Other resin material rollers that heat curing type is good can certainly be selected.
It is appreciated that the so-called substrate roller 100 of the present invention is inside it also containing heating element necessary to production fixing roller.
It is also coated with Heat Conduction Material in the inner peripheral surface of substrate roller 100 in one of the embodiments, to be conducive to substrate
100 internal heating element of roller generates heat and conducts to surface.
In one of the embodiments, on the outer peripheral surface of substrate roller 100 fluororesin-coated material in the substrate roller
It is formed before priming coat 110 on 100, further includes that the pre-heat treatment first is carried out to improve priming coat 110 and substrate roller to substrate roller 100
Adhesiveness between 100, specifically, the temperature of the pre-heat treatment are 30 DEG C -50 DEG C, and the time of the pre-heat treatment is 8min-12min.
S2, heat-shrinkable pipe 130 is coated the substrate roller 100 priming coat 110 outer peripheral surface, to be coated be heat-shrinked
Property pipe 130 and the priming coat 110 the first stage heating of the substrate roller 100, be warming up to the interior of the heat-shrinkable pipe 130
When the outer peripheral surface of circumferential surface and the priming coat 110 melts, then the processing that cools down is to get fixing roller.
Wherein, the stage heating is first progress first stage heating, i.e., with the heating speed of 6 DEG C/min-6.5 DEG C/min
Degree is warming up to 200 DEG C -220 DEG C, keeps the temperature 3min-8min.The main purpose of first stage heating is to exclude priming coat 110 and heat receipts
Bubble between contracting pipe 130.Then second stage heating is carried out, i.e., is heated up with the heating rate of 2 DEG C/min-2.5 DEG C/min
To 320 DEG C -350 DEG C, 10min-25min is kept the temperature.The main purpose of second stage heating is to make priming coat 110 and heat-shrinkable pipe
130 surfaces being in contact melt, that is to say, that the inner peripheral surface of the heat-shrinkable pipe 130 is outer with the priming coat 110
Circumferential surface melts.Sulphur occurs for the outer peripheral surface of the inner peripheral surface of heat-shrinkable pipe 130 and the priming coat 110 in melting process
Change reaction, forms close intermolecular force between heat-shrinkable pipe 130 and priming coat 110.In addition, heat-shrinkable pipe 130
Due to the heat shrinkable of itself, itself can shrink at high temperature, to further strengthen heat-shrinkable pipe and priming coat
Between binding force, cool down processing again later, so that it may obtain fixing roller.
In one of the embodiments, in the step of cooling down processing, cooling processing be with 2.5 DEG C/min-3 DEG C/
The cooling rate of min is cooled to 20 DEG C -30 DEG C.Fixing roller will be slow cooling under this cooling rate, avoid member inside fixing roller
Part generates deformation, or even rupture because of fast cooling.
Heat-shrinkable pipe 130 is being coated to the outer of the priming coat 110 of the substrate roller 100 in one of the embodiments,
It is on the outer peripheral surface for the priming coat 110 for being nested in the substrate roller 100 using heat-shrinkable pipe 130 in the step of circumferential surface.It is nested
Mode it is simple, it is easily operated.
The finish of the heat-shrinkable pipe 130 is 0.1Ra-0.3Ra in one of the embodiments,.Select this bright and clean
The benefit of the heat-shrinkable pipe 130 of degree is the fixing roller that is prepared in subsequent fixing, can reduce powder and paper because
The chance for rubbing and shifting, that is to say, that image distortion rate can be reduced.
In one of the embodiments, the heat-shrinkable pipe 130 with a thickness of 10 μm -100 μm.The thermal contraction of the application
Property pipe 130 thickness may be selected 100 μm, and traditional spray-coating surface applies the finishing coat finite thickness that the mode of material is formed, at most
It can only achieve 30 μm, such as overspray material again, there are the risks of material falls back, and can be too small because of thickness in fixing, pole
Easily loss is scrapped.
The material of the heat-shrinkable pipe 130 is selected from tetrafluoroethene perfluoroalkyl vinyl in one of the embodiments,
At least one of ether copolymer and polytetrafluoroethylene (PTFE).
In one of the embodiments, on the outer peripheral surface of substrate roller 100 fluororesin-coated material in the substrate roller
It is described applied to spraying in the step of forming priming coat 110 on 100.
In one of the embodiments, the fluorine resin material be selected from tetrafluoroethene perfluoroalkyl vinyl ether copolymer and
At least one of polytetrafluoroethylene (PTFE).
The preparation method of above-mentioned fixing roller is simple, specifically, first forming priming coat on the outer peripheral surface of substrate roller, then
Substrate roller is coated with heat-shrinkable pipe, then to carry out stage heating treatment equal to the surface that priming coat is in contact with heat-shrinkable pipe
It melts, vulcanization reaction occurs in melting process between contact surface, forms close molecule between heat-shrinkable pipe and priming coat
Between active force.In addition, heat-shrinkable pipe itself can be shunk at high temperature, to further strengthen heat-shrinkable pipe and priming coat
Between binding force, cool down processing again later, so that it may obtain fixing roller.Technique is applied compared to traditional primary coat-face, it is above-mentioned fixed
The preparation process of shadow roller is to prepare fixing roller in such a way that thermoplastic pipe coats substrate roller, and preparation method is simple, and avoids
The use of pollution chemical coating, energy conservation and environmental protection during conventional face applies.
