とを見い出した。(Prior Art) Conventionally, heat resistance deteriorates when wear resistance and uneven wear resistance are improved. Therefore, a tire having a cap-based structure is employed and a low heat-generating rubber is used as a base. In order to further improve durability and abrasion resistance, it is necessary to develop a base rubber having low heat generation. Therefore, there was a limit in using carbon black alone as a filler (filler). Therefore, we examined the combination of silica and carbon black as a filler, and by using a specific ratio of both and using a silane coupling agent and a specific binder in the base led, the performance as a base led was satisfied and low heat generation and high fracture tear strength were achieved. It was found that the cutting and chipping properties at the end of life were improved.

If the carbon black or silica exceeds 40 parts by weight or the total filler content of both exceeds 80 parts by weight, the rolling resistance deteriorates, and the wear at the final stage is not improved even if the reinforcing agent is increased, and the belt is not improved. There is a decrease in durability. If the amount of silica in the total filler is less than 25%, the rolling resistance and belt durability are not improved, and if it exceeds 75%, the cutting properties and abrasion at the end are not improved.

向上する。Various known silane coupling agents can be used as the silane coupling agent in the present invention. Typical examples thereof include γ-mercaptopropyltrimethoxysilane (union carbide, A1
89), γ-aminopropyltriethoxysilane (Union Carbide, A1100), bis [3- (triethoxysilyl) propyl] tetrasulfide (Degussa, Si-69
Etc.). When the amount of the silane coupling agent is less than 5% of the amount of silica, the reinforcing properties (hardness, lowering of modulus, tensile strength) are inferior, and the heat generation becomes worse. If it exceeds 20%, there is no significant difference in performance, but the cost is improved.

る。In the melamine derivative of the present invention, the higher the monomer content, the more excellent the vulcanized rubber exhibits dynamic properties, and the more the unvulcanized rubber compound exhibits high scorch stability. That is, when the monomer content is less than 60%, excellent dynamic characteristics and high scorch stability can be obtained even if the number of bound formalin and methoxy group per melamine molecule falls within the range of the present invention. Absent. When the monomer content exceeds 90%, it cannot be obtained by a normal production method, and a special purification step is required. Therefore, the production cost is greatly increased, and the industrial value is reduced. The content of the monomer is selected in the range of 60 to 90%.

を含有する系で顕著である。The ratio of methoxy groups to free methylol groups in the melamine derivative also has a significant effect on the dynamic properties of the vulcanized rubber and the processability of the unvulcanized rubber. In other words, even if the monomer content of the melamine derivative and the number of bound formalins per melamine molecule are constant, the smaller the number of methoxy groups, the greater the number of free methylol groups, and the dynamic properties of the vulcanized rubber are slightly improved. However, there is a point where the processability of the unvulcanized rubber is greatly reduced, and this tendency is remarkable in a system containing silica.
