DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective glazing agent for tires and wheels, and is not particularly limited, but is applied to tires and wheels of automobiles to impart gloss and stain resistance. The present invention relates to a protective glaze for tires and wheels exhibiting the following.

[0002]

2. Description of the Related Art Tires used in vehicles such as automobiles, bicycles and motorcycles, and wheels for automobiles, etc.
Because it is used near the road surface, it is in an environment where dirt such as soil, mud, dust and iron powder emitted from brake pads always adheres. For this reason, several protective glazes have been proposed that provide aesthetics to the surface of tires, wheels, and the like and maintain the cleanliness. Among them, those having a silicone oil as a main component and those having a wax as a main component have been already known as a polishing agent for a tire.

[0003] Silicone oil as a main component,
Although generally used because of its excellent gloss on the finished surface, most of it is a fluid with a high boiling point, so its dryness after application to tires is poor, and the finished surface will remain sticky, On the contrary, contaminants tend to adhere, and the contamination prevention effect (antifouling property) cannot be exhibited. In addition, even if water is washed with a detergent containing a surfactant to remove the adhered contaminants, silicone Due to oil and contaminants, there is a problem that the detergent or the like does not foam and the sponge or the like as a cleaning tool is stained black.

[0004] Those containing waxes as a main component are:
The tackiness of the finished surface can be suppressed, but wiping is required after application, and the gloss after the finish is inferior to those containing silicone oil as a main component.

Therefore, by using an acrylate polymer and / or a methacrylate polymer having a glass transition temperature of 0 to 50 ° C., good luster is imparted, there is no stickiness, there is little adhesion of dirt, and A glazing paint composition for tires that forms a coating film having excellent durability and water resistance has been proposed (JP-A-2000-144038). However, in order to improve water resistance and durability, this glazing coating composition forms a water-insoluble coating film on the tire surface.For example, the coating film once cracks upon contact with a curb on a road or the like. If it occurs or the coating deteriorates due to aging, it is difficult to remove it easily even if it is washed, and it is difficult to completely remove it. In addition to applying new paint to the paint, there is a problem that the appearance gradually deteriorates, and conversely, if you want to reduce the gloss,
There is a problem that the gloss cannot be easily reduced.
