Abstract

PROBLEM TO BE SOLVED: To inexpensively provide an elastic shock absorbing material excellent in visibility by kneading a recycling chip such as a waste tire in a thermally reactive resin, and sticking a light reflecting piece to a surface by performing heating molding by a metal mode in the elastic shock absorbing material such as a car stopping column. SOLUTION: A granular brown algae-like recycling chip obtained by pulverizing industrial waste such as a waste tire and waste plastic and a thermally reactive resin are kneaded to be injected into a metal mold to perform heating compression molding. Before hardening, a reflecting piece 3 excellent in light reflectivity such as a polygonal three-dimensional granular glass piece, a plastic piece and a crystal of silicon carbide is stuck to the surface by embedment and spraying. The reflecting piece 3 may be mixed in at chip kneading time. A light reflecting elastic shock absorbing material 2 molded in this way is fixed to a core material 4 arranged in the ground to form a car stopping column 1. This light reflecting elastic shock absorbing material 2 can also be used as a pavement material of a car stopping block, a curb stone and a road surface by changing a shape to thereby inexpensively provide the light reflecting shock absorbing material 2 excellent in visibility and durability.

I have.
The figure is a perspective view showing a state where the core member (4) is actually installed on a road surface, and a lower portion of the core member (4) is buried and fixed in the ground. More specifically, the core member (4) is a hollow metal tube or a plastic tube, and the reflecting piece (3) is any material that causes irregular reflection of light, such as a polygonal three-dimensional granular glass piece or a plastic piece. Can be. In particular, silicon carbide crystals widely used as abrasives have low cost,
Because of its excellent light reflectivity, it can be said that it is suitable for the application.

The light-reflective elastic cushioning material (2) is obtained by pulverizing waste tires and waste plastics into a kneaded product of granular / hidden recycled chips and a thermo-reactive resin into a molding die, and heat-press molding. However, the reflecting piece (3) may be mixed together during kneading as in claim 2, or may be buried on the surface during drying in the latter half of molding as in claim 1. Alternatively, it may be attached by spraying onto the surface. In any case, it is sufficient that one end of the reflection piece (3) is scattered in a state where it is exposed on the surface of the elastic cushioning material (2). In addition, if reinforcing fibers are mixed as in claim 3, the bending strength of the molded article is greatly improved, and a light-reflective elastic buffer material having more excellent durability can be obtained. The reinforcing fibers to be mixed include plastic fibers such as nylon and polyester, glass fibers, and the like.
Known fibers such as carbon fibers can be used.
