たタイヤに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention is a tire, in particular, a tire in which a 5 to 20 μm silicone oil film is formed on the surface of the tire to remarkably improve the appearance of the tire, particularly the appearance when it is stored for a long period of time. It is about.

があつた。Since a diene rubber is generally used as a rubber in a tire, a large amount of an amine anti-aging agent or paraffin wax is blended to satisfy the weather resistance. However, since these chemicals easily bloom in a short period of time, even if the tire is stocked at a tire dealer for a while, the surface of the tire discolors brown and the appearance of the tire remarkably deteriorates.

在しなかつた。Conventionally, many coating agents have been marketed in order to improve this defect and maintain the appearance of tires, but many of them do not have sufficient effects, and those having effects are conversely antiaging agents and paraffins. It is not useful because it interferes with the work of the system wax and prevents the original purpose of preventing ozone cracks from occurring in the tire. In addition, it is already known to use silicone oil as a polishing agent for automobiles, furniture and leathers (for example, April 20, 1945, published by Nikkan Kogyo Shimbun, written by Kimura Tamura, "Plastic Materials". See Lecture 6 Silicon Resin ", pages 65-66), which also suggests applying silicone oil to improve the appearance of the tire. Originally, a small amount of silicone oil was applied to a vulcanizing mold of a tire as a release agent (see
(See pages 9 to 170). In the case of aiming at such release, since the thickness of the applied silicone oil film is 1 μm or less, it hardly affects the appearance of the tire itself. In the case of using the above-mentioned known silicone oil in which silicone oil is applied to improve the appearance, it is necessary to make the coating film thinner than 5 μm even if it exceeds 1 μm. This is because when the film thickness is 5 μm or more, ozone cracks or innumerable small cracks similar to ozone cracks are generated from the middle to the end of use of the tire. However, under such a limitation of the film thickness, satisfactory maintenance of the appearance of the tire cannot be achieved at all, so that there has been no satisfactory coating agent for preventing the deterioration of the appearance of the tire stock.

の性能に悪い影響を与えないことをも目的とする。The present invention provides a tire in which the appearance of the tire is remarkably improved by applying it to the surface of the tire, particularly the deterioration of the appearance caused by discoloration due to blooming of amine-based antioxidants and paraffin waxes in long-term stock. It is also an object, but it is also an object of course that the application does not adversely affect the performance such as weather resistance and durability of the tire.

ムの表面部分の耐久性を低下させた為である。In the above-mentioned known technique in which silicone oil is used for improving the appearance of a tire, a satisfactory improvement in appearance has not been obtained as described above. However, when silicone oil is applied to the surface of the tire in a thickness of 5 μm or more, This is because the application thickness is limited because ozone cracks or innumerable small cracks similar to ozone cracks are generated during use. The reason why the cracks are generated when the film thickness is 5 μm or more is that a part of the silicone oil penetrates into the rubber and reduces the durability of the surface portion of the rubber.

コーンオイル被膜の厚さは５μｍ以上必要であることを
見出すに至つた。As a result of intensive studies, the inventors of the present invention increased the molecular weight of the silicone oil, and it is particularly important. However, if the low-molecular component (silicone oligomer) in the silicone oil is cut, the above problem, that is, the silicone oil It has been found that it is possible to prevent a part of the oil from penetrating into the rubber and lowering the durability of the rubber. Further, it was surprisingly found that when silicone oil is applied in a thickness of 5 to 20 μm, the appearance when stored for a long period of time can be kept almost the same as at the time of manufacture. This means that the silicone oil itself cannot prevent migration of antioxidants and paraffin waxes to the tire rubber surface, but even if such migration occurs, the silicone oil in the outermost layer of the tire is a liquid, so a uniform surface can be obtained. This is because the entire tire looks black because it does not diffusely reflect light. Then, they have found that the thickness of the silicone oil coating is required to be 5 μm or more in order to sufficiently bring out this effect.
シリコーンオイルの被膜の厚さを５〜２０μｍに限定し

リコーンオイルの被膜の厚さ７〜２０μｍがタイヤの外
観を維持するのに好ましい。The thickness of the silicone oil film is limited to 5 to 20 μm because if it is thinner than 5 μm, the effect of improving the initial appearance is small and the effect of maintaining the appearance when the tire is stored for a long time is not sufficient. On the other hand, if it is thicker than 20 μm, not only is the appearance glaring, which is not preferable, but silicone oil may make hands and other objects uncomfortable when carrying tires, or it may become slippery. is there. A silicone oil coating thickness of 7-20 μm is preferred to maintain the tire's appearance.

させるからである。前記揮発減量が１％以下であること
がゴムの耐久性を低下させない点で一層好ましい。In the present invention, the volatilization loss of the silicone oil at 150 ° C. for 2 hours is limited to less than 2%. When the amount is 2% or more, a large amount of low molecular weight components, that is, silicone oligomers are substantially present. This is because it diffuses and permeates, remarkably lowers the durability of the rubber, and causes ozone cracks and small cracks similar to ozone cracks. It is more preferable that the volatilization loss is 1% or less in that the durability of the rubber is not deteriorated.

粘度があつたほうが良い。In the present invention, the viscosity at 25 ° C. of the silicone oil containing dimethylsiloxane as the main component is limited to 1000 cst or more, because when it is lower than 1000 cst, the silicone oil is easy to come into contact with various objects during transportation of the tire. It is because it is taken away. Preferably, it should have a viscosity of 2000 cst or more.

Be improved. If it is less than 0.05 parts by weight, such an improving effect is not sufficient, and if it exceeds 5 parts by weight, the surface coated with silicone oil becomes white and the appearance is rather deteriorated, which is not preferable.

利点を有する。 According to the present invention, a surface treatment agent obtained by adding fluorinated mica in a specific weight ratio to a silicone oil containing dimethylsiloxane as a main component having a specific volatilization loss and viscosity is uniformly applied to a tire in a thickness of 5 to 20 μm. As a result, the appearance of the tire, particularly when stored for a long period of time, is significantly improved and the touch when touched with the silicone-coated surface is improved. It gives a tire whose function is not hindered. In the tire using the conventional coating agent, the improvement of the appearance and the retention of the function of the rubber chemicals are not compatible with each other, and the tire having the improved appearance and the improved ozone cracking resistance cannot be obtained. Therefore, the tire of the present invention has excellent advantages.
