Detailed description of the invention
It in order to illustrate the embodiments of the present invention more clearly, below will be to required use in embodiment or description of the prior art
Attached drawing do simple introduction, it should be apparent that, drawings in the following description are only some embodiments of the invention, for ability
For the those of ordinary skill of domain, without creative efforts, it can also be obtained according to these attached drawings other attached
Figure.
Fig. 1 is the sectional view of fixing roller of the embodiment of the present invention；
Fig. 2 is the sectional view of elastomeric layer of the embodiment of the present invention；
Fig. 3 is the partial enlarged view of elastomeric layer of embodiment of the present invention sectional view.
A specific embodiment of the invention is described in more detail below in conjunction with attached drawing.
Specific embodiment
Present invention will now be described in detail with reference to the accompanying drawings., when describing the embodiments of the present invention, for purposes of illustration only, indicating
The attached drawing of device architecture can disobey general proportion and do partial enlargement, and the schematic diagram is example, should not limit herein
The scope of protection of the invention.It should be noted that attached drawing is all made of very simplified form and using non-accurate ratio, only
To convenient, the clearly aid illustration embodiment of the present invention the purpose.
Referring to FIG. 1, FIG. 2 and FIG. 3, the fixing roller of the present embodiment includes mandrel 200 and elastomeric layer 100, elastic material
Layer 100 is covered in the peripheral surface of mandrel 200, and elastomeric layer 100 includes elastomeric material 101 and is distributed in elastomer material
Filler 102 in material 101, filler 102 are solid material, and the hardness of filler 102 is greater than the hard of elastomeric material 101
Degree.The elastomeric material 101 of the present embodiment uses silicon elastomeric material, specially silica gel (organic silicon rubber particle), filler
102 be glass microsphere made of silicon materials.Since the hardness of glass microsphere is greater than the hardness of silica gel, using by glass microsphere
The elastomeric layer 100 being mixed to prepare with silica gel is coated on outside mandrel 200, compared to fixing roller hardness made of porous silica material
It is higher, the hardness of fixing roller is improved without metal sleeve is additionally arranged again.In addition, the density of glass microsphere is 0.13~0.16
Between gram/cc, thermal coefficient is 0.06 watt/meter * degree), the respectively less than density and thermal coefficient of silica gel is micro- using glass
Ball can make fixing roller more light as filler, and thermal loss is less.Certainly, may be used also in other examples
Can be all kinds of rubber or rubber composition, such as chlorohydrin rubber, nitrile rubber, butylbenzene using other elastomeric materials
One of rubber several is mixed with.Filler can be iron powder or graphite etc..
The preparation method of fixing roller of the present invention is further described below, the preparation method of fixing roller includes following step
It is rapid:
Elastomeric material and filler are mixed, wherein the volume of filler accounts for all materials total volume (elastomer
Material+filler volume) percentage be less than or equal to 12%, it is preferred that when mixing the percent by volume of filler be 8%~
10%, since the hardness that the hardness of filler is greater than elastomeric material can make elastic material if the too high levels of filler
The excessive high hardness of layer is unfavorable for using therefore need to be by the ratio between filler and elastomeric material in a certain range；
Mixed elastomeric material and filler are stirred into (20 minutes), for the ease of the mixed of two kinds of materials
It closes, filler preferably uses the particle of spheroid form, and the diameter of sphere can be 25 microns~125 microns；
Mixture after the completion of stirring is vacuumized, mixed air in whipping process is removed；
Vulcanizing treatment is carried out to mixture, elastomeric layer 101 is made；Vulcanizing treatment processes work using conventional vulcanization
Skill, since vulcanizing treatment is carried out under high temperature (150 DEG C), filler needs high temperature resistant, such as at a temperature of 200 degree not
Can deformation occurs, glass microsphere at a temperature of 500 degree all will not deformation occurs, be therefore preferred filler material；In order to
Enough allow elastomeric layer more stable durable, vulcanizing treatment can be repeated 2 times or 2 times or more；
Elastomeric layer is covered in the peripheral surface of mandrel 200, elastomeric layer 101 and mandrel 200 are bonded in
Together, it then cut, polished, fixing roller is made.Mandrel 200 is made of metal material, such as iron, steel pole etc..
In order to make elastomeric layer and mandrel bond stronger, the mixture and core that are obtained after can also first vacuumizing
Axis is bonded together by Shooting Technique, i.e., the mixture of first coated elastomer material and filler in mandrel outer surface, so
Carry out vulcanizing treatment again afterwards.
In order to reduce the density of elastomeric layer, filler 102 can be hollow sphere (Fig. 3), the thickness of ball wall
Degree can be 2~3 microns.
Further, in order to increase the wearability of fixing roller, can also the outermost layer of fixing roller cover one layer it is wear-resisting
The non-metallic material bed of material 300, such as Teflon gum cover is set outside fixing roller.
Elastomeric layer is arranged in fixing roller of the invention outside mandrel, and it is higher to be uniformly distributed hardness in elastomeric layer
Filler particle does not need so that the hardness of fixing roller is sufficiently strong using metal sleeve；But also it can be by using low thermally conductive
The filler of coefficient remains the performance of the loss low in calories of porous material, while can be lighter, it is easier to be driven.
Certainly, technical concept of the invention is not limited in above-described embodiment, can also design according to the present invention obtain
Many different concrete schemes, for example, in addition to can use glass microsphere as filler other than, other can also be used to have close
Filler is used as like material of performance, such as expandable microspheres etc.；Filler can be sphere, be also possible to cube, spheroid
Deng, such as these change and equivalent transformation should be included in it is of the present invention within the scope of.
