ES2275446A1 - Ecological throw plate with or without paint includes a colophony derivative mixed with calcium carbonate - Google Patents

Abstract

The ecological throw plate with or without paint has 75 microns calcium carbonate 79 per cent and a colophony derivative 21 per cent respectively by weight. It can also incorporate on part of its surface at least e.g. acrylic biodegradable paint.

Description

Ecological shot plate.

The present invention relates to a plate of those used for shooting, being its shape, dimensions and weight the suitable to be projected using a machine plate thrower

Shooting plates are known as bowl that, launched by a machine, constitute a moving target fragmentable by the pellets projected during the firing of a gun

These dishes are composed of limestone (calcium carbonate) and pitch, used the latter as a binder. its color is black due to pitch, and can be painted externally to improve your vision by the shooter. Although the correct one pitch binder dosage allows to achieve a good fragmentation of the dish, the remains of it are dispersed by the field after having fulfilled its white duty mobile, being its complex and expensive withdrawal.

To solve the aforementioned problems, Proposed various ecological solutions. Thus, the document ES 1035467 U proposes a shot plate made of materials biodegradable that can be used as feed for hunting or as fertilizer for the ground. For its part, document ES 2160069 A proposes incorporating fertile seeds into the dish dough and animal feed correctors, such as medications or vitamins This type of organic dish, which presents more improvements theoretical that real leads inevitably to a high cost, both for the materials used and for the need for a manufacturing process very controlled in pressures and temperatures

Consequently, it is an objective of the present invention having an ecological firing plate that, realized with biodegradable substances keep a low price, both for the economy of the materials used as per the possibility of be made with minimal modifications to the facilities of production of conventional dishes.

The proposed solution lies in replacing the pitch binder by a rosin derived resin. This product is obtained from live pines, constituting a resource renewable whose extraction system is perfectly compatible with the preservation of the environment and that, in addition, allows the disintegration of the pieces of the shot plate once its mission as a moving target and subsequent leaching of the mass of calcium carbonate, which is itself a natural and harmless product. The absence of pitch, however, leads to a low product color so it is very convenient to proceed to painting, at least partial, of the plate of shot, for which they exist in the great market amount of biodegradable paints.

To complement the description above and for guidance and non-limiting purposes, a detailed description of a preferred embodiment.

It is evident that the consistency of the product final will be based on the quantitative composition of the materials involved in the manufacturing process thereof, as well as the temperature and pressure parameters in ovens, dispensers, dryers ... etc. These extremes will be amply known to the person skilled in the art.

Notwithstanding the foregoing it has been proven that the use of a rosin derivative as a binder in proportion 21% by weight together with a mass of calcium carbonate with a 75 micron particle size, constituting the remaining 79%, leads to a shot plate of the necessary robustness during handling but that offers excellent fragmentation qualities and subsequent disintegration Particularly advantageous is the use of the rosin derivative that is marketed under the name of RESIESTER 2002 by LA UNION RESINERA ESPAÑOLA, S.A.

Regarding paint, any product Biodegradable will be suitable, such as PRISMALUM 15 from PRISMATOM, S.L. in which the pigment is an organic precondensate microencapsulated, which uses an acrylic emulsion as vehicle.

The ecological shot plate made as just described presents some good features of disintegration which facilitates the leaching of calcium carbonate on the ground being, therefore, perfectly biodegradable.
