Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, those of ordinary skill in the art will Other similar embodiments obtained without creative work shall all fall within the scope of protection of this application.

[0030] Rubber for tire treads and sidewalls and protective wax form a solid solution. At higher temperatures, the protective wax is completely dissolved in the rubber. The solubility is poor. At this time, the protective wax is supersaturated in the rubber, so the protective wax migrates continuously from the inside of the rubber to the rubber surface, forming a uniform wax film. This wax film isolates the contact between the ozone in the atmosphere and the rubber surface. .

Abstract

The invention discloses a tire containing a rubber composition and a preparation method of tire rubber. The tire rubber composition comprises rubber for preparing the tire and blending protective wax,wherein the rubber for preparing the tire comprises natural rubber and / or synthetic rubber, the blending protective wax is formed by blending petroleum wax and biological wax, and the solubility parameter of biowax falls into the range of the solubility parameter of the rubber for preparing the tire. The tire prepared from the rubber composition provided by the invention not only can meet protection requirements of the tire against ozone aging in air, but also can obviously improve the occurrence of wax spraying and whitening phenomena of the tire and improve the appearance of the tire.

Description

technical field [0001] The invention belongs to the field of tire compound production, and in particular relates to a tire comprising a rubber composition and a tire rubber preparation method. Background technique [0002] There is a small amount of ozone in the air. Ozone molecules can react with the double bonds in diene rubber molecules to form bond breaks, which will cause aging cracks in the rubber and continue to develop in depth, causing damage to rubber products and premature loss of use value. For external compounds such as tire sidewalls and treads, in order to avoid damage to the tire rubber by ozone during daily use, a certain amount of protective wax will be added to form a uniform wax film on the tire surface to insulate the air. The ozone reacts with the unsaturated bonds of the polymer to play a physical protective role. [0003] However, in practical applications, the protective effect of protective wax is not satisfactory, and the phenomenon of whitening o...
