Definitions
- the present invention relates to a pneumatic tire using a sealant material.
- a gas such as air or nitrogen is contained in the tire so as to have an internal pressure of about 250 to 350 kPa as an absolute pressure, and tension is generated in the tire frame.
- the tension enables deformation or restoration of the input.
- the gas filled inside leaks out from the laceration portion, the internal pressure of the tire decreases to atmospheric pressure, and the tire enters a so-called puncture state.
- a sealant material which is a rubber composition having a viscous and appropriate fluidity, is disposed inside the tire.
- This is a technique for sealing a laceration and preventing a decrease in internal pressure by pouring a sealant material into the laceration using the internal pressure of the tire when a laceration occurs in the tire.
- the sharp foreign object when a sharp foreign object such as a nail is pierced while using the tire, the sharp foreign object may remain in a state of penetrating into the tire without immediately falling off. In such a state, the internal pressure in the tire does not decrease immediately. During the subsequent running, it receives a force that causes the foreign object to be pinched while stuck inside the tire. For this reason, the contact surface between the foreign matter and the tire rubs against each other, and the contact surface is worn to some extent, thereby forming a gap on the contact surface. If a foreign object suddenly detaches at a certain time, the internal pressure may decrease and the vehicle may become unable to run. In such a case, whether or not the sealant can be sealed depends on the followability or fluidity of the sealant.
- ⁇ Pneumatic tires support the load of the entire vehicle and generate heat while traveling, and therefore easily reach a temperature of several tens of degrees centigrade at any outside temperature.
- the tread portion although it is the outermost part in contact with the road surface, that is, the tread portion, it is naturally affected by the road surface temperature.
- the tread portion when traveling in a cold region in winter, the tread portion is also exposed to a temperature below freezing, and a temperature difference close to 100 ° C. is assumed inside and outside the tire.
- the road surface temperature also changes over several years to several tens of degrees Celsius. In view of recent developments in traffic networks and the spread of vehicles, movement across regions with large temperature differences is also increasing. Therefore, a pneumatic tire containing a sealant material is required to be able to cope with such a wide temperature range.
- the rubber composition used as the sealant material can appropriately change the properties such as the retention property, the fixing property, the followability, and the fluidity as described above depending on the blending.
- properties such as the above-described retention property, sticking property, followability, and fluidity change. Therefore, depending on the temperature range of the use environment, it becomes difficult to cope with one kind of sealant material.
- this problem has been solved by compensating for the amount of one kind of sealant material, but this leads to an increase in the weight of the tire, leading to deterioration in energy efficiency and an increase in the burden on the tire itself.
- the sealant layer is formed by depolymerization with a peroxide by the heat at the time of vulcanizing the rubber layer that forms the surrounding tire itself.
- the sealant composition may be made by a method that is not always easy to make.
- a pneumatic tire having a sealant layer in which two or more sealant materials blended so as to have different sensitivities to temperature are arranged, and the layer thickness of the sealant material by each blending and the layer thickness of all layers A pneumatic tire with excellent puncture-sealing effect.
- the present invention resides in the following (1) to (3).
- (1) It has a sealant layer disposed in a tire, and a sealant rubber composition is disposed in the sealant layer, which is distinguished as having different temperature sensitivity on the lumen side and the tire rubber side.
- a sealant layer having a viscosity ⁇ 1 of the sealant rubber composition on the lumen side and a viscosity ⁇ 2 of the sealant rubber composition on the tire rubber side at a speed of 1 s ⁇ 1 at 30 ° C. is ⁇ 1 / ⁇ 2 of 1.6 or more.
- a pneumatic tire characterized by being arranged.
- the sealant layer has two or more kinds of sealant layers that are independently distinguished from each other as a first sealant layer on the lumen side and a second sealant layer on the tire rubber side, and the viscosity of the first sealant layer at 30 ° C.
- ⁇ 1 / ⁇ 2 is 1.6 or more and the thickness averaged viscosity
- the layer thickness of the entire sealant layer is consequently obtained.
- a tire having a sealant layer that functions effectively even at the time of puncture can be provided while reducing the load applied to the pneumatic tire by reducing the bias of the weight and weight balance.
- two or more kinds of sealant materials prepared so as to have different sensitivities to temperature are arranged in two or more multilayers, and a sealant layer in which a function is shared for each corresponding temperature is arranged. It is characterized by that.
- a sealant material that is easy to operate in each of a plurality of temperature ranges divided into a plurality of high temperature to medium temperature to low temperature is arranged in layers.
- a space filled with a gas such as air or nitrogen is a contact surface with a rubber layer constituting the pneumatic tire, and a sealant material is disposed so as to be inserted into the contact surface.
- a gas such as air or nitrogen
- the contact surface side with the gas is the lumen side, and the one directly in contact with the rubber layer of the tire is the sealant layer, it is the radially outer side, that is, the direction side away from the center of the tire. Side, or simply the tire side. If another expression is used, it can be said that the tire rubber side is the outermost side. It can be said that the lumen side is the wheel side to which the tire is attached.
- first sealant layer 1 the one on the lumen 3 side is referred to as a first sealant layer 1 and the tire rubber 4 side is referred to as a second sealant layer 2.
- An intermediate sealant layer may be further disposed between the first and second sealant layers.
- the viscosity of the first sealant layer is ⁇ 1 Pa ⁇ s
- the viscosity of the second sealant layer is ⁇ 2 Pa ⁇ s. Note that both ⁇ 1 and ⁇ 2 indicate values at 30 ° C.
- a multilayer that gradually changes from the first sealant layer to the second sealant layer, and gradually It may be a continuously changing layer.
- the layers cannot be numbered consecutively, but the lumen side and the tire rubber side can be distinguished, and the respective viscosities are defined as above, the lumen side is ⁇ 1 , and the tire rubber side is What is distinguished as ⁇ 2 can be arranged.
- the ratio ⁇ 1 / ⁇ 2 is 1.6 or more. It is preferably 1.7 or more, and particularly preferably 2 or more.
- the reason for averaging the thickness is that the second sealant layer is on the outer periphery, so that the volume increases even with the same thickness, so that it is different from the averaging based on the volume and weight. However, since the first sealant layer and the second sealant layer are located far away from the center of the tire, the difference due to the circumference is not large, but the volume and the weight approximately proportional to the volume are averaged. Can be substituted.
- ⁇ 1 > ⁇ 2 is basically used.
- a “viscous” rubber composition having a viscosity ⁇ 1 that is exposed to the highest temperature is arranged on the lumen side, and the tire rubber side that is relatively relaxed to a low temperature has a viscosity ⁇ 2 . It is sufficient if a “loose” rubber composition is arranged. Loose rubber compositions tend to flow even at low temperatures, and sticky rubbers tend to stick even at high temperatures.
- the sticky sealant rubber will quickly move toward the laceration that is the communication path and occlude when it is sufficiently easy to flow. Become. If it does not reach a sufficient flow, the loose sealant rubber, which is easier to move, will move and bear the blockage. Thus, it can be said that the arrangement functions with fluidity corresponding to the shared temperature range.
- the sealant rubber layer according to the present invention is roughly divided into a sealant rubber composition having different temperature ranges to be borne on the high temperature side and the low temperature side, respectively. Yes.
- the respective layer thicknesses can be made less than 4 mm, and the layer thickness is preferably suppressed to 3 mm or less and further to 2 mm or less as a whole.
- the total layer thickness it is considered that when individual sealant rubber compositions are to flow, the responsiveness is improved and an advantageous effect by reduction is also produced.
- the sealant material of the rubber composition obtained in the present invention is disposed inside a pneumatic tire, and as defined above, the first sealant layer is in contact with a gas such as air or nitrogen filled in the tire. , Disposed in the lumen.
- the second sealant layer 2 is first disposed on the surface of the tire rubber portion 4 that is in contact with the tire lumen portion 3, which is a space in which gas is sealed, and the intermediate layer when there is an intermediate layer, Finally, the first sealant layer 1 is disposed.
- Each of the above layers is generally applied by a technique close to coating. Naturally, unless the tire laceration reaches the lumen, the internal pressure does not decrease due to gas leakage, so it is reasonable to place the sealant in the lumen, which requires the sealant to function only after reaching that position. Is.
- the contact surface with the gas may be covered so that direct contact does not occur. Further, it may be impregnated and held in a material having voids to the extent that appropriate fluidity is not hindered. In any case, when the laceration reaches the gas-filled portion, it is necessary that the gas that leaks out smoothly transports the sealant material to the lacerated portion.
- the sealant layer in order to make it easier to hold the sealant layer, it may be coated or impregnated, but it is particularly preferable to directly apply it without taking protective measures for coating or impregnation. If it can be arranged, the problem of excessive weight increase does not occur.
- Rubber components A to F for sealants having different viscosities at 30 ° C. were prepared by blending each component in 100 parts by mass of the rubber component in the parts by mass shown in Table 1.
- Rubber compositions B and C are mainly different in plasticizers due to process oil and polybutene, and the accompanying compounding is also changed, but the viscosity is close, so the difference due to the layer arrangement shown in Table 2 is the next.
- the viscosity was measured based on JIS Z8803 using a cone plate viscometer at a shear rate of 1 s ⁇ 1 and a temperature of 30 ° C.
- Ethylene-propylene-diene rubber EP35, manufactured by JSR * 2: Bromobutyl rubber: Bromobutyl 2255 manufactured by JSR Corporation * 3: Carbon black: N330 * 4: Liquid polybutene: JX Nippon Mining & Energy Co., Ltd., Nisseki Polybutene HV300 * 5: Process oil: Dyna Process Oil NR26, manufactured by Idemitsu Kosan Co., Ltd. * 6: Tackfire: ZEON, Quinton A100 * 7: Vulcanization accelerator: Tetrabenzylthiuram disulfide: Sunseller TBZTD, manufactured by Sanshin Chemical Industry Co., Ltd.
- the rubber compositions from A to F excluding C were used as sealant rubbers and arranged at the thicknesses shown in the table.
- the air sealability at each temperature was evaluated as a: successful seal, b: incomplete seal, and c: seal failure.
- any rubber composition one type is stacked by 1 mm, that is, a single composition is used in a thickness of 2 mm. Sealing was not possible in the entire temperature range from room temperature to low temperature. To seal with a single composition, a thickness of 4 mm is required as in Comparative Example 3.
- the above comparative examples are shown for comparison with the examples. From the viewpoint of the temperature range where sealing was successful, A is a high temperature range, B to E are room temperature ranges, and F is a low temperature range. It can be said that it is a sealant rubber suitable for.
- Example 7 Although the viscosity averaged about thickness satisfy
- the viscosity averaged for the thickness satisfies the condition, but the viscosity ratio does not reach the predetermined value 1.6, and the viscosity ratio does not reach 1, that is, the arrangement order is suitable in the first place.
- Comparative Examples 8 and 9 which were reversed from those, the sealing was not achieved.
- Comparative Example 5 and Example 4 which are equivalent to the viscosity averaged with respect to the thickness, the success or failure of sealing is not determined only by the viscosity.
- the larger layer thickness of Example 5 is advantageous for sealing, but A, B, and D, which have higher viscosities, are used. Considering that 4 is not sealed at all temperatures, it can be said that the success or failure of sealing is not determined by viscosity alone.

厚さについて平均化した粘度、第1と第2シーラント層の粘度比が所定の条件を満たす2種のシーラントゴムを用いた、実施例1~3はいずれも全温度域での封止に成功した。実施例4は、高温域で封止不完全であるが許容範囲である。さらに、第1シーラント層を2mmと厚くして配置した実施例5は全温度域で封止成功した。また、厚さについて平均化した粘度が条件を満たすが、粘度比が所定の値1.6に達していない比較例7、さらに粘度比が1にも達しない、すなわち、そもそも配置順が好適なものと反転している比較例8、9は封止には至らなかった。厚さについて平均化した粘度について同等の比較例5と実施例4から明らかなように、単に粘度だけで封止の成否は決まらない。比較例5と実施例5の層厚において、実施例5の層厚が大きい点は封止に有利であるが、より粘度が高いA、B、Dを用いている、比較例1、2、4も全温度では封止ができていないことを合せて考えると、やはり粘度だけでは封止の成否は決まらないといえる。
