Problems solved by technology

[0002] 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 space is that the end point of the 1# belt layer begins to tear in the direction of the belt cushion rubber. Therefore, improving the performance of the belt layer cushion rubber is taken as the direction to improve the shoulder space

Abstract

The invention relates to an all-steel load-bearing radial tire belt mat rubber which is prepared from the following raw materials in parts by weight: 80-120 parts of SMR10#, 25-40 parts of carbon black N326, 5-15 parts of silica white, 0.8-3.2 parts of liquid isoprene rubber, 2-8 parts of nano zinc oxide, 0.5-3.5 parts of stearic acid, 1-3 parts of silane coupling agent Si69, 0.7-2.3 parts of dispersing agent FNS-78T, 1-3 parts of 204 resin, 0.5-2.5 parts of anti-aging agent 6PPD, 0.5-1.5 parts of microcrystalline wax and 0.4-1.6 parts of anti-aging agent TMQ. The SMR10#, carbon black, silica white, liquid isoprene rubber and nano zinc oxide are adopted in the all-steel load-bearing radial tire belt mat rubber; and a low-heat-generation technique is utilized to effectively improve the radial tire shoulder heat generation, so that the quality problems of early shoulder separation and the like of the tire are greatly reduced, and the early shoulder separation is lowered from 10% to 1% or so.
