Technical field
The present invention relates to and make inner liner, separation layer, casingply is stacked and the airtyred manufacture method obtained and pneumatic tire and airtyred manufacturing installation.
Background technology
Usually, as shown in Figure 7, pneumatic tire 1 is made by following manner: from internal layer side, stacking gradually inner liner 6, separation layer 7, the casingply 5 and carcass portion 2 obtained configures fetus face 3, thus mold green tire, and sulfidization molding is carried out to this green tire, thus make described pneumatic tire 1.In addition, 4 is bead part.
(a) of Fig. 8 is the amplification sectional view in the carcass portion before sulfidization molding, and (b) of Fig. 8 is the amplification sectional view in the carcass portion after sulfidization molding.As shown in (b) of Fig. 8, if carcass portion cures, then separation layer 7 is sucked between the body cord 8 of casingply 5, thus waviness phenomena occurs, and the thickness of carcass portion entirety is not enough, likely produces and bursts at the seams.Particularly, in tire shoulder (buttress) partly (by the part that X represents in Fig. 7) waviness phenomena that easily generation is such of the heavy duty tire such as TBR tire.
Therefore, in the past with the thickness of separation layer 7 (gauge) for target, such as thickened about 0.5mm and tackled, but this and day by day to strengthen in recent years the light-weighted requirement of tire is runed counter to.
So, propose following scheme: electron ray (EBR:Electron Beam Radiation is irradiated to casingply 5 or separation layer 7, electron beam irradiation) and become semi-cure state, thus improve the Mooney viscosity of rubber, namely, make rubber hardening, prevent the suction (such as patent document 1,2) of separation layer 7.

Detailed description of the invention
Below, utilize accompanying drawing based on embodiment the present invention will be described.
Fig. 1 is the airtyred manufacture method of application present embodiment and the amplification sectional view in airtyred carcass portion that produces.
The airtyred manufacture method of present embodiment is identical with existing airtyred manufacture method in the following areas: by attaching inner liner 6 successively, separation layer 7, casingply 5 carry out stacked, thus mold the green tire being formed with carcass portion 2, and sulfidization molding is carried out to this green tire, manufacture pneumatic tire.
But, the airtyred manufacture method of present embodiment is different from existing airtyred manufacture method in the following areas: before being laminated on separation layer 7 by casingply 5, the adhesive tape 10 becoming semi-cure state be attached between separation layer 7 and casingply 5.
Like this, the adhesive tape 10 becoming semi-cure state is being attached at shaping birth tire between separation layer 7 and casingply 5, and when sulfidization molding is carried out to this green tire, become the adhesive tape 10 of semi-cure state Mooney viscosity rise thus hardening, therefore separation layer 7 can be suppressed to be sucked up between body cord 8, the generation of waviness phenomena can be prevented.In addition, even if do not increase the thickness of separation layer 7, also can prevent the generation of waviness phenomena, thus can suppress the increase of tire weight.
Further, owing to not needing as in the past separation layer 7 or casingply 5 to be irradiated to electron ray and become semi-cure state, the various problems accompanied with the situation of irradiating electron ray to separation layer 7 or casingply 5 can not therefore also be produced.
In present embodiment, airtyred concrete manufacture can be carried out according to following steps.
(1) making of adhesive tape
First, adhesive tape is made by extrusion process etc. in the same manner as the making of general tyre rubber material.
Now, as the proportioning of rubber, be preferably the rubber proportioning identical with separation layer 7.Thus, fully can guarantee the cementability with casingply 5, in addition, can form as one by the separation layer 7 identical with rubber proportioning after sulfidization molding, because of but preferred.In addition, such adhesive tape also can by making slitting for the sheet rubber of separation layer 7.
The width of adhesive tape 10 is preferably 100mm ~ 300mm.If be less than 100mm, then the suction of rubber likely occurs in the both sides of adhesive tape, on the other hand, if more than 300mm, then manufacturing cost likely uprises.Be more preferably 150mm ~ 250mm.
The thickness of adhesive tape 10 is preferably 1mm ~ 3mm.When being thinner than 1mm, likely the unfavorable conditions such as air enters occur when attaching between separation layer 7 and casingply 5, on the other hand, if more than 3mm, then the tire weight after manufacturing likely becomes large.Be more preferably 1.5mm ~ 2.5mm.
(2) the semi-cure process of adhesive tape
Then, carry out making made adhesive tape 10 become the process of semi-cure state.This process is carried out preferably by the electronbeam irradiation being such as easy to suitably manage semi-cure state, makes the adhesive tape after processing reach the hardness of the degree that can prevent waviness phenomena.
Herein, as electron beam irradiation device, preferably use scanning electron beam exposure apparatus or domain type electron beam irradiation device.
One example of the beam exposure apparatus of scanning electron shown in Fig. 2.Scanning electron beam exposure apparatus 20 is configured to: to be boosted by Cockcroft-Wal circuit that pauses as irradiation voltage by the accelerating potential provided by DC high-voltage power supply (can use at below 5000kV), utilize accelerating tube 21 by this high voltage dividing potential drop.In addition, utilize accelerating electrode 22 pairs of electron raies to carry out multistage acceleration, with flying-spot tube 23, electromagnetic scanning is carried out to the point-like electronics after acceleration, thus be extended to required irradiation width, after controlling electron stream 25, electron ray is irradiated from illumination window 26 to adhesive tape 10 by controlling the temperature of filament 24.
Like this, scanning electron beam exposure apparatus 20 is owing to having flying-spot tube 23 and needing a large amount of shielding materials shielded the high-octane X-ray produced by high accelerating potential, thus shape becomes larger, but electronics can be made to enter to depths in adhesive tape 10 by high accelerating potential.Specifically, electronics can be made under the accelerating potential of 300kV ~ 500kV to be enter to 1.5mm in the adhesive tape 10 of 1 at proportion, and now the transporting velocity of adhesive tape 10 is maximum can be adjusted to 45m/min.Therefore, scanning electron beam exposure apparatus 20 is preferably as being suitable for high-tension electron beam irradiation device, be suitable for the rubber that the needs such as two-sided rubberizing rubber (プ ラ イ ト ッ プ is anti-) carry out at wide region irradiating, the adhesive tape of small-sized casing ply can be preferred for.
Then, an example of domain type electron beam irradiation device shown in Figure 3.Consist of: the accelerating potential provided by DC high-voltage power supply 31 (principle is 300kV to the maximum) is boosted as irradiation voltage by voltage-multiplying circuit, the potential difference of between negative electrode 32 and ground 1 grade is only utilized to accelerate electron ray, control in the electronics zonally produced by a large amount of filaments 33 arranged according to required irradiation width by electrical means, thus control electron stream 34, irradiate electron ray from illumination window 35 to adhesive tape 10 afterwards.
Like this, in domain type electron beam irradiation device 30, because accelerating potential is low, the energy of thus produced X-ray is also low, does not need a large amount of shielding materials.Therefore, device entirety can be made small-sized and lightweight.In addition, owing to electronically controlling electron stream 34, thus the up-flow time is short.But, on the other hand, because accelerating potential is low, be thus difficult to make electronics to the depths entered in adhesive tape 10.Specifically, under the accelerating potential of 250kV ~ 300kV, only make electronics be enter to about 0.5mm in the adhesive tape 10 of 1 at proportion, and the transporting velocity of adhesive tape 10 also slow, be 1.5m/min ~ 15m/min.Therefore, domain type electron beam irradiation device 30 is preferably as the electron beam irradiation device being suitable for low-voltage-big current, be suitable for the rubber that needs irradiate deeper at close limit, can be particularly preferred for only to the situation that the necessary position of adhesive tape is irradiated.
In present embodiment, the irradiation voltage of preferred electron ray is 200kV ~ 600kV.When being less than 200kV, likely cannot obtain fully through ability, on the other hand, if more than 600kV, then becoming excessive through ability, the plastic sheet in order to prevent adhesive tape bonding to be each other attached at the adhesive tape back side even being made to go bad, likely make plastic sheet cannot regeneration.Be more preferably 300kV ~ 600kV.
In addition, the irradiation dose of preferred electron ray is 50kGY ~ 150kGY.When being less than 50kGY, electron ray can through thickness thin, likely cannot obtain sufficient semi-cure state, on the other hand, if more than 150kGY, then sulfuration may excessively be carried out.Be more preferably 80kGY ~ 130kGY.
As a concrete example of the illuminate condition of preferred electron ray, preferably when irradiation voltage is 300kV, irradiation dose is set as 100kGY ~ 150kGY.
Further, the illuminate condition of above-mentioned electron ray is preferably suitably adjusted, to control the Mooney viscosity of adhesive tape for 70 ~ 100.By Mooney viscosity being controlled, for described scope, easily to obtain the adhesive tape 10 that semi-cure has become to prevent the suitable rubber hardness of waviness phenomena, and suitable cohesive can be kept.
In present embodiment, preferred above-mentioned electron beam irradiation device is such as configured between the adhesive tape calender device of green tire production line and roll of adhesive strip winding apparatus online.
(3) attaching of the adhesive tape of semi-cure state
Then, as shown in Figure 1, on assembly drum, the adhesive tape 10 becoming semi-cure state above by semi-cure process is attached between separation layer 7 and casingply 5.
Now, adhesive tape 10 is attached at whole between separation layer 7 and casingply 5, but is preferably only attached at the shoulder portions (part represented with X of Fig. 7) that waviness phenomena the most easily occurs in carcass portion 2.Thus, the consumption of adhesive tape 10 can be reduced, thus can realize the further lightweight of tire, particularly can obtain larger effect in the heavy duty tire such as TBR tire.
In addition, as adhering device, such as adhesive tape attaches mechanism and preferably possesses adhesive tape adhering device adhesive tape 10 being supplied to the adhesive tape feedway on casingply 5 and supplied adhesive tape 10 being attached to casingply 5.
In addition, when this attaching, adhesive tape 10 is preferably made to fit with casingply 5 in advance.Thus, the attaching of elastomeric material when molding green tire can be carried out efficiently, the raising of productivity ratio can be realized.
Now, the mode preferably contacted with casingply 5 according to the face of the illuminated electron ray side of adhesive tape 10 attaches, and thus, the hardening face of adhesive tape 10 is configured at casingply 5 side, can suitably prevent rubber to be sucked between body cord 8.
In addition, in present embodiment, be provided with casing ply delivering mechanism further to attach adhesive tape 10 in the rear side of casingply 5.
(4) green tire is shaping
Afterwards, by comprise inner liner 6, separation layer 7, the adhesive tape 10 becoming semi-cure state, casingply 5 tyre rubber material carry out stacked on assembly drum successively, thus mold green tire.
(5) sulfidization molding of green tire
Then, the green tire molded is accommodated in sulfuration mould, applies pressure and heat, thus carry out the sulfidization molding of green tire, make pneumatic tire.
In this case, owing in advance the adhesive tape of the hard rubber layer with semi-cure state being attached between casingply and separation layer, separation layer in sulfidization molding therefore suitably can being prevented to be sucked between plies cords and to produce waviness phenomena.
Particularly in the airtyred situation of heavy duty, as shown in the photo of Fig. 4, in airtyred existing manufacture method, separation layer is easily sucked and produces waviness phenomena, but by using the airtyred manufacture method of present embodiment, as shown in the photo of Fig. 5, easily can manufacture the pneumatic tire that waviness phenomena obtains suitably suppressing.
In addition, even if in the airtyred situation of passenger car, the waviness phenomena shown in photo of Fig. 6 also can be prevented, therefore, even if the thinning thickness being attached to separation layer inside whole tire compared with the past, also can maintain required intensity fully.Its result, can make contributions to the airtyred lightweight of passenger car.
In addition, the separation layer thickness in tire circumference becomes even, can prevent the generation that the thinning tire caused in thickness local is bad, can reduce tire drag.
In addition, the adhesive tape of having irradiated electron ray can be used, configure the adhesive tape of appropriate size as required, thus, compared with the situation to separation layer WBR electron ray, significantly can cut down material cost.
