Problems solved by technology

[0003] All-steel radial truck tires are prone to early quality problems under harsh and complex conditions, the most prominent of which is the shoulder space, especially under early overloading. The existing all-steel Aromatic hydrocarbon oils lead to problems such as frequent shoulder voids in the early stage, poor tire overload resistance, and low retreading rate, which reduces the quality of tires, reduces the service life of tires, and causes large economic losses to many companies. After a large number of defective tires are tested According to the cross-sectional analysis, the starting damage point of the shoulder is that the end point of the 1# belt begins to tear in the direction of the belt pad. Therefore, improving the performance of the belt pad is taken as the direction to improve the shoulder

Abstract

The invention relates to all-steel radial truck tire belt layer pad rubber capable of improving tire shoulder separation. The all-steel radial truck tire belt layer pad rubber comprises, by weight, 100 parts of SMR10#, 34 parts of carbon black N326, 10 parts of white carbon black, 2 parts of liquid isoprene rubber, 5 parts of nano zinc oxide, 2 parts of stearic acid, 2 parts of silane coupling agent Si69, 1.5 parts of dispersing agent FNS-78T, 2 parts of 204 resin, 1.5 parts of antiaging agent 6PPD, 1 part of microcrystalline wax, 1 part of antiaging agent TMQ, 1.6 parts of epoxy resin I, 10 parts of flaky silver powder, 22 parts of hydroxyl polydimethyl siloxane and 6 parts of carrageenan. The all-steel radial truck tire belt layer pad rubber has the advantages that the SMR10#, the carbon black, the white carbon black, the liquid isoprene rubber and the nano zinc oxide are used in the all-steel radial truck tire belt layer pad rubber, the low heat generation technology is utilized, the radial tire shoulder heat generation is improved effectively, quality problems such as early shoulder separation of tires are reduced greatly, and the early shoulder separation is lowered from the original 10% to about 1%.
