Provided is a high-productivity rubber composition having excellent adhesiveness to a reinforcing member, particularly a reinforcing member in environmental degradation, and capable of bringing high peel operability therewith. The rubber composition is obtainable by compounding a rubber component containing a diene based rubber, a wet silica, a carbon black and a calcium carbonate, wherein: a compounding amount of the wet silica is 3 parts by mass or more and less than 5 parts by mass per 100 parts by mass of the diene based rubber; and a compounding amount of the calcium carbonate is 10 parts by mass or more and 120 parts by mass or less per 100 parts by mass of the diene based rubber.

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.
