Abstract
Disclosed is a rubber composition which enables, when used in a tread rubber for a tire, to improve initial grip performance and traveling stability of the tire as compared with conventional tires. Specifically disclosed is a rubber composition which is obtained by blending a C9 resin containing indene, which has a softening point of 130 DEG C to 190 DEG C and an indene content of 30-80% by mass, in a rubber component.
Description
Technical field
The tire that the present invention relates to rubber combination and use it, more particularly, compare the initial earth-catching property that improves tire and the rubber combination of riding stability with conventional tire thereby relate in tire tread glue, using, and the tire that in tread rubber, uses this type of rubber combination.
Background technology
Be desirably in the high-performance tire tyre surface that uses in the racing car etc. and keep good control stability (DRY adherence properties) to dry pavement when finishing from the beginning of travelling.Therefore, to be in DRY adherence properties (initial earth-catching property) in the initial travel phase of relative low temperature in order improving at tire, to have studied so far compoundings such as tenderizer that the oil ingredient that will comprise low softening point resin and liquid polymers and occurs at low temperatures wave effect to the rubber combination that is used for tread rubber.
For example, compounding has C
9The rubber combination of aromatic resin etc. is disclosed in JP-A-H05-9336, wherein consider mixing during the dispersiveness of resin, will have softening temperature and not be higher than 140 ℃ C
9The aromatic resin compounding is to said composition.And compounding has the rubber combination of aromatic vinyl compound to be disclosed in JP-A-H10-195238 and JP-A-H10-195242, and wherein compounding has softening temperature and is not higher than 140 ℃ resin.
Yet, when this type of has the standby rubber combination of resin of low softening point by compounding, and when making tire with this rubber combination in tread rubber, initially earth-catching property is improved, but during travelling, earth-catching property raises along with the tire tread temperature and reduces.On the other hand, when for improve travel during tire earth-catching property (riding stability) in the tyre temperature rising situation, separately with high softening point resin such as C
9The compoundings such as resin are during to rubber combination, and the initial earth-catching property of tire on the low temperature road surface significantly reduces.
As the method that solves problems, consider with high softening point resin and low softening point resin both compounding to the method for rubber combination.Therefore yet the resin total amount of compounding is influential to the temperature profile of rubber combination, but compounding to the amount of resin of rubber combination is limited.As a result, the tire that obtains by the method all is being medium aspect initial earth-catching property and the riding stability.Therefore, need to be provided for can be simultaneously taking into account the rubber combination of the tire tread glue of the initial earth-catching property of tire and riding stability with higher level.
Summary of the invention
The inventor has studied rubber combination that how deteriorated use compounding has low softening point resin and have a good initial earth-catching property as the earth-catching property during the travelling of the tire of tread rubber, and find: even on identical distance, significantly change the degree of deteriorated earth-catching property by pavement temperature.That is, find: be not higher than at pavement temperature under 10 ℃ the condition, the riding stability of tire is difficult to reduce, and on the contrary, surpasses under 40 ℃ the condition at pavement temperature, and the riding stability of tire is easy to reduce.
And, find: when the vehicle that is equipped with in tread rubber the tire that uses above-mentioned rubber combination travels in pavement temperature is 42 ℃ annular distance, measure under steam tire internal temperature, behind about 10 circles that travel, tire internal temperature is increased to 100 ℃-110 ℃.Because the measurement to tire internal temperature is carried out after vehicle is sailed the reason place of returning something for repairs, so this internal temperature during prediction is travelled becomes higher.The rubber combination that compounding has a low softening point resin is in that to be higher than dynamic modulus under 100 ℃ (E ') large aspect deteriorated, what therefore worry is when the internal temperature of the tire that obtains by this type of rubber combination of use in tread rubber becomes higher, this rubber combination is softening with resin, thus deteriorated riding stability.
Therefore, the tire that the purpose of this invention is to provide rubber combination and in tread rubber, use this type of rubber combination, described rubber combination can use in tire tread glue, thereby compares initial earth-catching property and the riding stability of improving tire with conventional tire.
For achieving the above object, the inventor has the rubber combination with resin that E ' is high under the high temperature to carry out various researchs to having the effect and the compounding that reduce E ' under the room temperature, and finds: the C that can contain by compounding indenes
