Water-based treatment agent for forming rubber-reinforcing cord, rubber-reinforcing cord formed using same and production method therefor, and rubber product employing rubber-reinforcing cord

摘要

It is an object to improve the anti-fraying properties of rubber-reinforcing cords without significant reduction in productivity. The present invention provides a water-based treatment agent for forming a rubber-reinforcing cord having a coating. The water-based treatment agent includes a rubber latex, a crosslinking agent, and a filler. A content of the crosslinking agent is 50 parts by mass or more and 150 parts by mass or less per 100 parts by mass of solids contained in the rubber latex, and a content of the filler is more than 50 parts by mass and 80 parts by mass or less per 100 parts by mass of the solids contained in the rubber latex.
