ない。2. Description of the Related Art In recent years, from the viewpoints of environmental protection and energy saving, it has been required to reduce the weight of pneumatic tires used for automobiles and the like. By the way, in a tubeless tire among pneumatic tires, an inner liner made of rubber having a high gas barrier property is provided inside the tire in order to prevent air leakage and suppress a decrease in the internal pressure of the tire. Inner liners are also targeted for weight reduction measures. Conventionally, halogenated butyl rubber has been mainly used for the inner liner.However, if the thickness of the inner liner made of halogenated butyl rubber is simply reduced to reduce the weight, the gas barrier properties will also be reduced, which is necessary. However, there is a disadvantage that the internal pressure retention is impaired. Then, in order to solve this, a technique for greatly improving the gas barrier properties of the rubber composition itself has been proposed. Specifically, it is a method of blending a layered mineral or blending a thermoplastic resin. Since these rubber compositions have extremely high gas barrier properties, an extremely thin inner liner is sufficient to secure the level of internal pressure retention that can be achieved by the current inner liner made of halogenated butyl rubber. Therefore, it is calculated that the weight of the tire can be considerably reduced. However, in this case, since the thickness required for the inner liner is too small, the inner liner is extremely poor in workability, such as breakage or pinholes, and lacks practicality. Therefore, at present, the merits of weight reduction by these rubber compositions cannot be fully enjoyed.

工性が悪化する恐れがある。DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail. First, a rubber composition layer that can be used as an inner liner will be described. The ratio of flat particles in this rubber composition
200 to 320 parts by weight per 100 parts by weight is preferred. If the amount is less than 200 parts by weight, it is difficult to obtain the effect of the compounding. If the amount exceeds 320 parts by weight, processability may be deteriorated. The role of the flat particles blended in the rubber composition is considered as follows. In other words, due to the stress applied to the extrusion process and the rolling process, the flat particles are oriented to form a layered structure, which becomes an obstacle in the event of air leakage, lengthens the air leakage path, and as a result, improves the air blocking performance It seems to do. Therefore, the degree of flatness of the particles is preferably as a particle size.
0.2-2 μm, and / or 5-30 as aspect ratio,
More preferably, it is 8-20. When the particle size is less than 0.2 μm or the aspect ratio is less than 5, it is difficult to form a layer structure, and the improvement of the air barrier property becomes insufficient. As a result, the weight of the tire cannot be reduced, while the particle size is 2 μm. If the ratio exceeds 30 or the aspect ratio exceeds 30, workability may be deteriorated during tire production.

の効果は得られても、重量低減効果が得られ難くなる。The material of the flat particles is preferably a mineral, and among them, kaolin, clay, mica, feldspar, silica, graphite, bentonite, alumina, and a water-containing complex of alumina are more preferably used. These may be used alone or in combination. Further, the particles may have a layered structure such as mica. On the other hand, it is preferable that the rubber component of the rubber composition contains butyl rubber such as isobutylene-isoprene copolymer rubber (IIR) and a halide thereof because air permeability can be reduced. Furthermore, when this rubber composition layer is used particularly as an inner liner, it is 0.10 to 0.1.
Preferably it has a thickness of 50 mm. When the thickness is less than 0.10 mm, in addition to the difficulty in obtaining the air blocking property, it is difficult to form a uniform thickness so that defects such as pinholes do not occur. If it exceeds 0.50 mm, it is difficult to obtain the weight reduction effect even though the air blocking effect is obtained.

The thermoplastic resin film can be used for the main purpose of reinforcing the rubber composition layer in the tire manufacturing process, and the film has a breaking elongation of 80% or more, and / or an elongation of 50%. Is preferably 2000 g or less per 1 cm width. If the elongation at break is less than 80%, the film cannot follow the expansion of the member during the tire manufacturing process, the film is broken, and as a result, the rubber composition layer becomes discontinuous, and the internal pressure retention of the tire becomes poor. When the tension per 1 cm width at an elongation of 50% exceeds 2000 g when the unvulcanized tire is left in the tire molding process, the unvulcanized tire deforms due to the film tension, or Peeling of the film occurs, making it difficult to obtain a normal product tire. As the material of the film, it is preferable to use a polyester resin, a nylon resin, a polynitrile resin, a polyvinyl resin, a polyolefin resin, etc., and they may be used alone or in combination.

It preferably has a thickness of 3 to 100 μm. When the thickness is less than 3 μm, it is difficult to obtain the reinforcing property as a support layer,
If it exceeds μm, it has an adverse effect on weight reduction. The thermoplastic resin film according to the present invention may be removed after the completion of the tire, or may be left in a tire product as a part of the product, and a method of using the film can be appropriately selected.
When the tire is to be removed after completion, the rubber composition layer is placed on the carcass side, the thermoplastic resin film is placed inside the tire, and after vulcanization, only this film is peeled off and removed from the tire. On the other hand, in the case of without removing the thermoplastic resin film in the product tire, the air permeation coefficient of the film is not more than 5.0 × 10 -12 cm 3 · cm / cm 2 · sec · cmHg, the film The substance itself is preferable because it can exhibit a function as a gas barrier layer.

Of the two-layer laminates used in the tires of Examples 1 to 4 and Comparative Examples 4 and 5, in Example 2, only the inner liner was disposed on the carcass side, that is, the film was disposed inside the tire, and the other was the reverse. That is, the inner liner was placed inside the tire. In the examples in which the films of Examples 1, 3, 4 and Comparative Examples 4 and 5 are adjacent to other members, in order to secure the adhesiveness between the film and the other members (specifically, carcass), An adhesive (Chemrock 234B, manufactured by Lord Far East Co.) was applied to this surface of the film (that is, the surface on the side opposite to the inner liner of the film).

生じ、加工性が悪化している。 Discussion of the Results Compared with the tire using the current inner liner of Comparative Example 1, the air leaking property of Comparative Example 2 is improved because flat particles are blended in the inner liner. However, the weight of the tire has not been reduced because the thickness of the inner liner remains unchanged. On the other hand, Comparative Example 3 is Comparative Example 2
Since the inner liner having the same composition as that described above was merely made thinner, the weight was reduced, but the inner liner was cracked and the workability was deteriorated.

It can be seen that the stacking order does not affect the effect. However, if it is desired to remove the support layer after vulcanization, the structure of Example 2,
That is, it is naturally required to adopt a structure in which the film is inside the tire. All of these tires have thinner inner liners, but since the tires are made in a two-layer structure with the support layer, they do not impair workability and have good air leakage, and , Weight reduction has been achieved. The appearance of the product was also good.

り、このようなタイヤも効果的であることが判った。In the tire of Comparative Example 4, since the cutting elongation of the film serving as the support layer was small, the film was cracked during the production of the tire, and the tire performance could not be measured. On the other hand, in Comparative Example 5, the film tension was too strong,
The tire was separated from the tire before vulcanization, and the tire performance was not measured as in Comparative Example 4. Examples 3 and 4
Is an example in which the material of the film was changed, and good results were obtained as with PET, regardless of whether the film was made of 6-nylon or polyvinylidene chloride. In particular, the polyvinylidene chloride film used in the tire of Example 5 had a very small air permeability coefficient, and thus could cooperate with the inner liner to significantly improve the air leakage. Furthermore, for the tire of Example 2, after measuring the performance in the two-layer structure, detached from the rim, peeled off only the film, again assembled this rim, and measured the air leakage in the same manner. In addition, the peeling operation was smooth, and it was found that such a tire was also effective.

Accordingly, when this layer is used as an inner liner, the thickness of the inner liner can be reduced, and the weight of the tire can be reduced. On the other hand, the workability, which tends to decrease due to thinning, can be compensated for by laminating a thermoplastic resin film. Furthermore, when the thermoplastic resin film is made of a resin having a high air-blocking property, air leakage can be prevented with both the rubber composition layer and the thermoplastic resin film, so that the internal pressure holding property can be made extremely high. it can.
