Description of the Related Art Zinc oxide has been widely used in a wide range of fields such as pigments, catalysts, pharmaceuticals, cosmetics, photosensitizers, and sensors, but it has also been used as a rubber reinforcing material and a vulcanization accelerating aid. .. The zinc oxide is produced by a gas phase reaction method (French method) in which zinc vapor produced by heating metallic zinc or zinc ore is oxidized, a zinc salt is treated with a solvent to be converted into zinc carbonate, and this is used. A wet method (American method) of roasting and converting into zinc oxide is known. Among them, the zinc oxide obtained by the former method has a relatively large powder particle size of a few microns, and the latter method has an average particle diameter. It is possible to obtain finely divided zinc oxide of submicron level.

な状況にあって、必ずしも適格な方法とはいえない。Normally, zinc oxide (zinc white) produced by a gas phase reaction method is used as a rubber reinforcing material or a vulcanization accelerating aid, but as described above, this powder has a relatively large particle size. Due to the large relationship, the specific surface area is small, so the prescribed effect cannot be obtained unless a large amount is blended. Therefore, if the fine zinc oxide powder obtained by the wet method is used, the blending amount can be reduced. However, since both zinc oxide and rubber are easily negatively charged, they repel each other and the dispersion in the rubber does not proceed smoothly. For this reason, zinc oxide is usually used as a means of adding it to the compound at an early stage. However, when shortening the kneading time has become a common sense in the industry as in recent years, this method cannot be said to be effective. come. To solve this problem, there is a method of pre-coating the surface of zinc oxide with an acidic compound such as zinc propionate so that the surface is positively charged. For example, it is commercially available under the trade name "POSITOX R". .. However, in the case of this type of commercial product, it is difficult to obtain the type of zinc oxide desired by the user due to certain restrictions on the properties of the raw material zinc oxide, such as the particle size. Therefore, it is not necessarily a qualified method.

耗性を付与することが可能となる。[Function] The zinc oxide composite carbon black compounded in the rubber composition of the present invention has extremely stable composition properties because the particle size of the zinc oxide particles to be composited is 200 nm or less, which is equivalent to that of the carbon black aggregate. However, during rubber compounding, this stable composite morphology functions to give good uniform dispersion. In addition, because of the presence of zinc oxide in the vicinity of carbon black, the bond between rubber and carbon black during vulcanization becomes strong, and since the particle size of zinc oxide is small and the specific surface area is large, the action with the rubber component is enhanced. Through these actions, if the particle size of carbon black is the same, it becomes possible to impart relatively excellent strength and wear resistance with a small amount of zinc oxide.
