DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a waste golf ball composition plate of the present invention will be described with reference to the drawings. FIG. 1 (A)
FIG. 1 is a perspective view showing the configuration of a golf ball waste material composition plate, and FIG.
(B) is an enlarged sectional view of the composition plate. The golf ball waste material composition plate 1 is made from a golf ball disposed of at a golf course or a driving range. Golf balls are roughly classified into thread-wound golf balls and two-piece golf balls. A thread-wound golf ball generally has a structure in which a thread rubber made of natural rubber or synthetic polyisoprene is wound around a center made of polybutadiene rubber or a liquid contained in a rubber bag, and the outermost layer is covered with an ionomer resin. It is.

A two-piece golf ball generally has a structure in which polybutadiene rubber or the like is mainly used as a core base material, and an outermost layer is covered with an ionomer resin. The above 2
There is also a one-piece golf ball other than the types of golf balls, but this one-piece golf ball is a simple golf ball used in a driving range or the like. In this case, polybutadiene rubber is often used as a base rubber. As described above, these golf balls use polybutadiene rubber as a base rubber. In the case of solid balls, the weight percentage of the polybutadiene rubber generally reaches 80 to 90% of the entire golf ball. Since polybutadiene rubber is used as a base material for golf balls, it is superior to rubber used for old tires in terms of abrasion resistance, durability, and excellent elasticity over a long period of time. There is a feature.

The ionomer resin is an ionic ethylene-based copolymer resin having an ethylene-unsaturated carboxylic acid-based copolymer as a base resin, and is a resin which is hardly damaged, and has excellent durability and impact resistance. The present inventor paid attention to the composition of the above golf ball, and set the golf ball as a waste material to 0.1 m
After pulverizing or cutting into a size of m to 15 mm (preferably 3 mm to 10 mm), the mixture is kneaded and kneaded using a urethane-based resin binder or the like, and fixed in a state having a gap for allowing water to pass through. To manufacture.
In FIG. 1 (B), the granular material 2 indicates a pulverized polybutadiene rubber or an ionomer resin, the filament 3 indicates a natural rubber or the like as a thread member of a thread-wound golf ball, and the reference numeral 4 indicates a particulate by a binder. It shows a place where objects and the like are connected, and reference numeral 5 shows a water-permeable gap.

As the binder, besides urethane resin binders, cement and water glass can be used as inorganic substances, natural rubber and cellulose can be used as organic substances, and thermoplastic resins such as polyvinyl and polyethylene, and phenols can be used. A thermosetting resin such as epoxy or the like can be appropriately applied. According to this paving board, it is excellent in water permeability, elasticity and abrasion resistance, so it is most suitable for pavement materials in poolsides, places where a large amount of water is required and materials that do not burden people's feet are required. . Further, since the pavement plate has excellent soundproofing and does not slip, it is most suitable for rugs on stairs in apartments where rainwater is applied.

FIGS. 2A and 2B are views for explaining a second embodiment of the present invention, and FIG.
(B) It is an equivalent figure. The second embodiment is characterized in that the sintered body 7 having glass as a main component and having a large number of closed cells is formed by using a binder to form a gap 5 by using a binder.
The point is that the tile 9 having a two-layer structure is manufactured by laminating the golf ball waste material composition 1 described in the first embodiment on the glass sintered body composition 8 fixed in a certain state. The size of the sintered body 7 is 0.1 mm to 15 mm.
The size has become. Although the golf ball waste material composition plate 1 is composed of rubber as its main component, it is heavy in weight. However, by laminating it on the glass sintered body composition 8, there is an advantage that the drainage property of the golf ball waste material composition is good. In addition, it is possible to provide a light tile 9.
