あるからである。[0003] Salt water resistant adhesion is important for pneumatic tires, conveyor belts, and the like. For example, salt (NaCl) is sometimes sprayed on icy roads to melt the snow, but in this case, when tires run on this road, salt water enters through cuts in the tread, causing the steel in the belt layer to infiltrate. This deteriorates the adhesion between the cord and the coated rubber (rubber composition), eventually resulting in the destruction of the tire. Further, in conveyor belts installed on the coast, salt may infiltrate due to the sea breeze, which may reduce the adhesion between the steel cords and coated rubber that make up the conveyor belt.
