Benefits of technology

[0006]This invention relates to a projectable target made from a composition comprising a filler material and an improved binder for the filler material. The binder comprises a mixture of asphalt and an asphalt modifier selected from polymers, waxes, asphaltites, and combinations thereof. In one embodiment, the asphalt modifier is a combination of pol

Problems solved by technology

Certain pitches have undesirable properties and are unsuitable for clay pigeons.
Currently available supplies of acceptable pitch are becoming scarce and inadequate to meet demand.
Prior efforts to find alternate materials have produced unsatisfactory results, such as the pigeons being too brittle, not acceptably frangible, too expensive, or otherwise failing to meet consumer requirements.

[0051]A projectable target is made by molding a composition including a filler material and a binder. The binder is a mixture of asphalt, hydrocarbon resin and wax. The asphalt is a solvent extracted asphalt which is oxidized to a softening point within a range of from about 140° C. to about 180° C., and more particularly from about 140° C. to about 160° C. The asphalt has a penetration of about 0 dmm at 25° C. The hydrocarbon resin has a softening point within a range of from about 120° C. to about 175° C. The hydrocarbon resin is included in an amount within a range of from about 5% to about 40% by weight of the binder, more particularly from about 10% to about 30%. The wax is included in an amount within a range of from about 1% to about 10% by weight of the binder, more particularly about 5%.

Abstract

A projectable target is made from a composition including a filler material and a binder for the filler material. The binder includes a mixture of asphalt and an asphalt modifier selected from polymers, waxes, asphaltites, and combinations thereof. In one embodiment, the asphalt modifier is a combination of polymer and wax, and the binder has a penetration from 0 dmm to 5 dmm at 25° C., a softening point from 80° C. to 175° C., and a viscosity from 1000 centipoise to 25,000 centipoise at 163° C. The composition is formed into the shape of the projectable target and hardened.

Description

BACKGROUND OF THE INVENTION[0001]This invention relates in general to projectable shooting targets of the type commonly referred to as clay pigeons, and in particular to compositions for use in manufacturing the targets.[0002]In trap and skeet shooting, saucer-shaped targets are projected into the air by means of an ejection device past the location of the marksmen. The marksman's intention is to hit the flying target by a shot from a shotgun causing it to disintegrate. In addition to being able to disintegrate when hit by shotgun pellets, the targets are also manufactured to withstand transportation and handling, and to withstand the strain they are subjected to when projected.[0003]The properties of the shooting targets have typically been achieved by using as starting material a mass consisting of pitch (coal tar or a petroleum pitch) and a filler material such as limestone powder or clay. In this mixture, the pitch acts as a binder for the filler material.[0004]Certain pitches h...
