Abstract
The present invention is directed to a novel, low-toxicity red smoke generating composition and a method of making the same, comprising at least one red dye, a coolant, an oxidizer, a non-sugar binder, and a non-sulfur particulate fuel that is also a burn-control agent having at least one particle size distribution. Preferably, the red dye comprises an anthracene or anthraquinone-based dye and the fuel comprises a sugar or mixture of sugars.
Claims21
A low-toxicity red smoke generating composition, comprising:
- an oxidizer;
- a particulate non-sulfur fuel having a particle size range of 10 to 100 microns, and wherein said fuel further includes second particles having a particle size range of 300 to 650 microns;
- at least one anthracene or anthraquinone-based red dye;
- a coolant;
- and
- a non-sugar binder.
A process for producing a low-toxicity red smoke generating grenade, comprising:
- mixing an oxidizer;
- a non-sulfur fuel, wherein said fuel comprises a mixture of sucrose having a particle size range of 10 to 100 microns and further includes sucrose having a particle size range of 300 to 650 microns;
- at least one anthracene or anthraquinone-based red dye;
- a coolant;
- and a non-sugar binder to form a mixture;
- loading said mixture into a body as a solid charge;
- loading an ignition composition into said body;
- sealing said body;
- and
- attaching an igniter to said body to form a smoke grenade.
