The surface contacted with formed body 1A of release sheet 5 is above-mentioned smooth during body 1A vulcanization.
Hereinafter, the step of manufacture method of the conveyer belt of the present invention, is illustrated.
As illustrated in fig. 1, formed body 1A is configured between hot plate 8a, 8b.Hot plate 8a, 8b surface relative to each other point
Do not covered by release sheet 5.
Next, as illustrated in fig. 2, move hot plate 8a, 8b at least one party in a manner of hot plate 8a, 8b are close, if
To be clamped by hot plate 8a, 8b and being fixed formed body 1A state.In this condition, release sheet 5 is between upper covering rubber 3 and hot plate
Between 8a and between lower covering rubber 4 and hot plate 8b.As illustrated in fig. 3, release sheet 5 turns into hot plate 8a, 8b plane
Rubber 3 and the lower length direction (being in figure 3 left and right directions) for covering rubber 4 and width are covered in covering (in Fig. 3
In for above-below direction) the state that contacts of gamut.
Releasing axle 9a turns into fixed mode, and winding off spindle 9b turns into the state that rotation driving stopped, right in the longitudinal direction
Release sheet 5 imparts appropriate tension force.Can be by after it will release axle 9a and be set to fixed mode, rotation driving winding off spindle slightly
9b, so as to assign tension force to release sheet 5.That is, each supply machine 9,9 can be made to be filled as the tensioning for assigning tension force to release sheet 5
Put and play function.Preferably, by adjusting winding off spindle 9b rotation amount, desired tension force is assigned to release sheet 5.Assign
Tension force be the bottom line that release sheet 5 is not tensioned setting loosely tension force.Predetermined is being assigned to release sheet 5
During power, it is difficult to produce fold etc. in release sheet 5, the surface of the conveyer belt 1 to making to have vulcanized turns into smooth favourable.
With it is upper covering rubber 3 and it is lower covering rubber 4 contact when release sheet 5 temperature be preferably set to more than 50 DEG C and into
Below body 1A curing temperature.Specifically, by the temperature of release sheet 5 now be set to such as more than 50 DEG C and 120 DEG C with
Under.
The state that release sheet 5 is set to (more than 50 DEG C) higher than low temperature can suppress the generation of fold etc..For example, continuously make
In the case of with release sheet 5, when the release sheet 5 of the condition of high temperature is changed into low-temperature condition, easily produced because of thermal contraction in release sheet 5
Raw fold etc..On the other hand, when the temperature of release sheet 5 is set into higher than formed body 1A curing temperature, release sheet 5 becomes to hold
Easy heat deterioration.
It will be clamped as described above by hot plate 8a, 8b and fix formed body 1A scheduled time of state maintenance, with predetermined
Temperature is heated to formed body 1A and is pressurizeed and vulcanized with predetermined pressure.Predetermined temperature (vulcanization during vulcanization
Temperature) it is such as more than 140 DEG C and less than 165 DEG C, predetermined pressure is such as more than 2.0MPa and below 4.0MPa.
In the vulcanization, unvulcanized upper covering rubber 3 and lower covering rubber 4 flow.Here, set release sheet 5 not being situated between
In the case that ground has vulcanized formed body 1A, unstable interface, hot plate between hot plate 8a and unvulcanized upper covering rubber 3
Unstable interface between 8b and unvulcanized lower covering rubber 4 will become on the direction of the dump energy elimination at interface respectively
Change, change turns to the immediate mutual state of surface energy.Also, the surface energy of rubber is than hot plate 8a, 8b surface energy
Greatly, if the recesses such as scar be present on hot plate 8a, 8b surface, in the dump energy at interface to be eliminated, rubber easily collects
In in recess.That is, the upper covering rubber 3 of flowing, lower covering rubber 4 preferentially enter from the coarse part on hot plate 8a, 8b surface
Row absorption.As a result, in the not coarse part on hot plate 8a, 8b surface, it is impossible to the dump energy of rubber is eliminated, and can be by sulphur
The rubber surface residual changed is concavo-convex, so the surface of the conveyer belt 1 to making to produce turns into smooth unfavorable.
On the other hand, in the present invention, the release sheet that sandwiched water contact angle is more than 70 °, the coefficient of kinetic friction is less than 0.3
5 and formed body 1A is vulcanized, so release sheet 5 and covering rubber 3 between interface, release sheet 5 with it is lower covering rubber 4
Between interface without the inequality (Japanese of surface energy：Inclined り).Moreover, upper covering rubber 3 and lower covering rubber 4 are relative
Smoothly flowed in release sheet 5, so the surface of the conveyer belt 1 produced is smoothened.Accompany with this, also can be in vulcanization
By being fully exhausted between upper covering rubber 3 and lower covering rubber 4 and release sheet 5.In addition, it is upper covering rubber 3 and/or
The composition of lower covering rubber 4 is difficult to the surface for being attached to release sheet 5, can be repeated to make with the state of no dirt so also having
The advantages of with release sheet 5.
By the vulcanization, formed body 1A cures and turns into conveyer belt 1 (part for conveyer belt 1).Formed body 1A's
After vulcanization, hot plate 8a, 8b at least one party are moved in a manner of hot plate 8a, 8b are separated, makes to contact with the conveyer belt 1 produced
Release sheet 5 peel off.Release sheet 5 has the characteristic that water contact angle is more than 70 °, so can hold from the conveyer belt 1 produced
Change places stripping.
Then, the part (part vulcanized) for the conveyer belt 1 for making to produce is moved to the front on length direction, will be into
The part of body 1A following vulcanization is configured between hot plate 8a, 8b as the example shown in figure 1.Next, carry out already described
Same process and formed body 1A is vulcanized.At this point it is possible to reuse release sheet 5 in part used in previous vulcanization
(part contacted with formed body 1A), different parts can also be used.In the case of using different parts, it will release
Axle 9a switches to free schema, makes winding off spindle 9b rotation drivings, and release sheet 5 is released into necessary length in the longitudinal direction.Pass through
So formed body 1A is staggered in the longitudinal direction successively and vulcanized, so as to manufacture conveyer belt 1.
Can also be in a manner of supplying machine 9 without using piece, for example in hot plate 8a lower surface, hot plate 8b upper surface difference
Release sheet 5 is detachably set.In the case where release sheet 5 is detachably arranged at into hot plate 8a, 8b, it is preferred that
Jie sets the elastic components such as spring, is set to impart release sheet 5 state of predetermined tension force and be installed on hot plate 8a, 8b.
In the present invention, make release sheet 5 between hot plate 8a, 8b and formed body 1A and vulcanized, so even if not
Using the coccoids such as talcum powder and/or releasing agent, can also prevent conveyer belt 1 and hot plate 8a, the 8b produced the demoulding it is bad,
Hot plate 8a, 8b dirt etc..Therefore, do not have by the deterioration of the caused operating environment that disperses of talcum powder and/or releasing agent etc..
In addition, also will not be in surface attachment dirt as caused by talcum powder and/or releasing agent of the conveyer belt 1 produced.Also without
The operation of talcum powder and/or releasing agent etc. is removed from hotplate surface, so also being improved favorably to the productivity ratio of conveyer belt.
And then the piece thickness of release sheet 5 is below 0.4mm, so setting the ground of release sheet 5 to formed body 1A progress sulphur with not being situated between
The situation of change is compared, and cure time is degree elongated slightly.If the piece thickness of release sheet 5 becomes too thin, under operability
Drop, so piece thickness is set into more than 0.2mm.The surface of the conveyer belt 1 so produced no matter macroscopically or it is microcosmic on
All turn into flat, turn into smooth surface and inhibit the excellent product of the presentation quality of the attachment of dirt.
As illustrated in Fig. 4, Fig. 5, as release sheet 5, it can also use and bury by the thermal conductivity material more excellent than its mother metal
Expect the piece of reinforcer 6 formed.In the release sheet 5, reinforcer 6 by with vulcanization at least in the piece table contacted with formed body 1A
The state that face is not exposed is buried.Reinforcer 6 can also be unexposedly completely embedded on the surface of release sheet 5.In addition, reinforcer 6
Can also endlong it be buried on the width of release sheet 5.
As reinforcer 6, can specifically use such as aluminium flake, various sheet metals, glass fiber sheets.It will be stripped
When piece 5 is set to such specification, it is difficult to produce fold etc., the table to making conveyer belt 1 in release sheet 5 because of the presence of reinforcer 6
Face turns into smooth favourable.Moreover, can also avoid cure time because of reinforcer 6 this elongated unfavorable condition.
Embodiment
When being vulcanized clamping unvulcanized rubber slab sample by hot plate, only make being contacted with rubber slab sample for hot plate
Face specification it is different like that as shown in table 1 and vulcanized (comparative example 1,2 and embodiment 1,2).In comparative example 1
Hot plate has used SS400, and SKD61 has been used in hot plate in comparative example 2.Make hard chrome plating (HCr) layer in embodiment 1 between heat
Between plate and rubber slab sample.Make diamond-like-carbon (DLC) layer in example 2 between hot plate and rubber slab sample.It is right
Each specification confirms the pollutional condition of hotplate surface, the results are shown in table 1.The pollutional condition of hotplate surface passes through to as production
Vulcanization number untill the dirt (dirt influence actual production) of raw practical upper obstacle is evaluated.The numerical value of the vulcanization number
It is bigger, then mean that the pollution of hotplate surface is fewer.
Table 1
As can be known from the results of Table 1, embodiment 1,2 compared with comparative example 1,2, lack by the pollution of hotplate surface.In addition, implementing
In example 1,2, the smooth surface of the sample vulcanized is also able to confirm that.
