Description of the Related Art Conventionally, a glazing agent for rubber products has a solvent type of dimethyl polysiloxane (hereinafter referred to as dimethyl silicone) as a main component and 10 to 20% by weight of the dimethyl silicone component diluted with a CFC solvent or an interface. An aqueous type has been used in which an activator is used and an emulsion of 10 to 20% by weight of a dimethyl silicone component is used.

とするものである。However, although the solvent type is superior in blackness and gloss to the aqueous type, it is inferior in ease of application and easily spotted, and is contained in rubber. To elute anti-aging agents,
Swells rubber to accelerate deterioration. Further, the one in which dimethyl silicone is dissolved in a chlorofluorocarbon-based solvent is the mainstream, and it has become an environmental problem that the volatilized solvent destroys the ozone layer. On the other hand, the water-based type has good workability, but is still insufficient in gloss and gloss durability, water repellency and water repellency. Therefore, an amino group-containing organopolysiloxane (hereinafter referred to as aminosilicone), which is effective for water repellency, water repellency durability, and gloss durability, has come to be used. However, when aminosilicone is used, a reddish brown discoloration is observed, so that there is a drawback in that it loses its original function as a glossing agent, such as a loss of gloss and a reddish tire. An object of the present invention is to provide a protective glazing agent for tires in which the above drawbacks are eliminated.
