The present invention provides a water-repellent elastic body composition that is easy to manufacture, easy to manufacture, easily recovers water repellency, and does not stain the contact surface, a method for manufacturing the same, and a friction member using the same. In a water-repellent elastic composition 10, a part of an inorganic filler 12 is exposed on the surface, and a water-repellent film-forming molecule 14 is covalently bonded to the exposed surface of the inorganic filler 12, whereby a water-repellent film is formed. 15 is formed. The water-repellent elastic body composition 10 is formed by forming a water-repellent film on the surface of the inorganic filler 12 exposed on the surface of the elastic body molding 13 formed by mixing the resin 11 having elasticity and the inorganic filler 12 and molding the mixture into a predetermined shape. It is manufactured by a manufacturing method including a step of covalently bonding molecules 14 to form a water-repellent film 15. [Selection] Figure 1 |
