Abstract
The invention belongs to the technical field of rubber compositions and in particular relates to a rubber composition for tires. The rubber composition is prepared from the following components in parts by weight: 35-60 parts of ethylene propylene rubber, 10-20 parts of carbon black, 8-15 parts of 2,5-bis(tert-butylperoxy)-2,5-dimethylhexane 45 and 5-10 parts of N774. The rubber composition provided by the invention is relatively high in breaking strength, simple in process and low in cost and is prepared from easily available raw materials, and the operation stability can be improved when the rubber composition is used in a tire material.
Description
Technical field
The invention belongs to Rubber composition technology field, particularly relate to a kind of rubber combination for tire.
Background technology
For SUV tire with for requiring the tire of the superior automobile of increased durability (comprising those areas in hot area and the bad area of road conditions), except low fuel consumption performance, guarantee that manipulation stability and breaking tenacity (weather resistance) are also important.Breaking tenacity with cutting resistance and resistance to be separated growth property relevant, and for guaranteeing that the method for breaking tenacity comprises following method: (1) replaces silicon-dioxide with carbon black; (2) reduce the content of filler, and the divinyl rubber comprising the syndyotactic polyhutadiene crystal of 1,2-makes up rigidity and the crack growth resistance of reduction.But, aforesaid method (1) can not meet the requirement improving E* and reduce tan δ simultaneously, and because the dispersiveness of the easier deteriorated filler of aforesaid method (2) and tan δ, therefore the requirement improving E* and reduce tan δ can not be met sufficiently.In addition, the available divinyl rubber comprising the syndyotactic polyhutadiene crystal of 1,2-of reduction that the content because of filler reduces the E* caused carries out making up to a certain degree, but when the content of filler excessively reduces, can cause the reduction of breaking tenacity.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, a kind of rubber combination for tire possessing high breaking tenacity is provided.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of rubber combination for tire, its special character is that its component is counted by weight: the ethylene-propylene rubber(EPR) of 35 ~ 60 parts, the carbon black of 10 ~ 20 parts, the N774 of two 2 5-45 and 5 ~ 10 parts of 8 ~ 15 parts.
Further, a kind of rubber combination for tire, its special character is that its component is counted by weight: the ethylene-propylene rubber(EPR) of 50 ~ 60 parts, the carbon black of 10 ~ 15 parts, the N774 of two 2 5-45 and 7 ~ 10 parts of 12 ~ 15 parts.
Further, a kind of rubber combination for tire, its special character is that its component is counted by weight: the ethylene-propylene rubber(EPR) of 60 parts, the carbon black of 15 parts, the N774 of two 2 5-45 and 8 parts of 12 parts.
The invention has the beneficial effects as follows: rubber combination of the present invention possesses higher breaking tenacity, manipulation stability can be improved in for tire material.Present invention process is simple, and raw material is easy to get, with low cost.
