Abstract

The invention relates to a steel wire glue stock for a belted layer of a tire and a preparation method of the steel wire glue stock. The steel wire glue stock comprises the following various components by weight: 100 parts of natural rubber, 0.1-0.3 part of a peptizer, 30-60 parts of carbon black, 8-15 parts of white carbon black, 5-10 parts of zinc oxide, 0.5-4 parts of stearic acid, 1-5 parts ofan antiager, 1-3 parts of resorcinol, 1-5 parts of an adhesive, 2-6 parts of insoluble sulfur, 0.5-2 parts of an accelerant, and 0.1-0.4 part of a scorch retarder. The final glue stock is prepared sequentially through primary master mixing, secondary master mixing, and final mixing in the preparation. The preparation method is simple, the steps are easy to operate, the cost of the process is relatively low, the prepared glue stock and a steel wire keep excellent drawing force of the steel wire, and the retention rate of the drawing force of the aged glue stock meets the use requirement of thetruck and bus radial tire.

Description

technical field [0001] The invention relates to a tire belt steel wire rubber compound and a preparation method thereof, belonging to the technical field of tire manufacturing. Background technique [0002] In recent years, with the rapid development of China's automobile industry, China's tire industry is also developing steadily. At present, China has become the world's largest tire producer, but also the world's largest tire market. However, the lack of core tire technology in my country has not been completely changed with the expansion of the industry scale and market and the improvement of manufacturing technology. Therefore, vigorously developing new technology and new formula is the only way to realize the transformation of my country from a big tire manufacturing country to a tire powerful country. [0003] Cobalt salts are important adhesion promoters for bonding tire compounds to copper-coated steel wires. In tire compound formulations, cobalt salts are usually...
