Sodium lignosulfonate, when present, acts as a dispersant of the carbon powder facilitating the preparation of the paste, and potassium nitrate acts as a combustion activator and regulator of the burn rate. The starch, when present, acts as a regulator of the viscosity and rheological behavior of the paste. Inert ingredients can be used inorganic salts, for example, sodium bicarbonate, and / or organic co-solvents, for example, alcohols, glycol ethers, etc. The bonding agents are compounds that act by facilitating and improving the adhesion of the band of combustible composition containing the active substance to the support. Among the adherent agents that can be used are, for example, polyvinyl pyrrolidones (PVP) and modified cellulosic derivatives, such as hydroxy (alkyl) cellulose, for example, hydroxyethyl cellulose, or carboxy (alkyl) cellulose, for example , carboxy methyl cellulose, etc.

Por su parte, las pastas correspondientes a las composiciones [l]-[3], [6] y [7] se preparan dispersando el almidón en agua; mezclando, en seco, los componentes sólidos; añadiendo la mezcla en seco de los componentes sólidos sobre la dispersión acuosa de almidón, en una relación sólidos : dispersión acuosa de almidón de, aproximadamente, 1:1; y adicionando los componentes líquidos restantes.Different water-based pastes were prepared containing the compositions [1] - [8], in dry weight, indicated in Table 2. To prepare the pastes corresponding to the compositions [4], [5] and [8] (without starch), the appropriate amounts of the solid components are mixed dry, the resulting mixture is added to water, and finally, the rest of the liquid components of the composition are added. On the other hand, the pastes corresponding to the compositions [1] - [3], [6] and [7] are prepared by dispersing the starch in water; dry mixing solid components; by adding the dry mixture of the solid components over the aqueous starch dispersion, in a solid ratio: aqueous dispersion of starch of about 1: 1; and adding the remaining liquid components.
Tabla 2Table 2
Como sustancias activas se utilizaron insecticidasAs active substances insecticides were used
(composiciones impares) y ambientadores (composiciones pares) . En todos los casos, los insecticidas y ambientadores utilizados eran productos comerciales existentes en el mercado.(odd compositions) and air fresheners (even compositions). In all cases, the insecticides and air fresheners used were commercial products in the market.
La pasta obtenida se aplicó mediante técnicas serigráficas sobre un soporte de papel resistente a la llama, dibujando una huella en forma de zig-zag y se secó con aire caliente a 50°C durante 30 minutos.The paste obtained was applied by screen printing techniques on a flame-resistant paper support, drawing a zig-zag footprint and dried with hot air at 50 ° C for 30 minutes.
Para comprobar la eficacia de los dispositivos obtenidos para vaporizar la sustancia activa se prendió con una cerilla uno de los extremos de la huella comprobándose (por el olfato y la vista) que, al ir avanzando la fuente de calor a lo largo de la huella, se iba vaporizando la sustancia activa. To verify the effectiveness of the devices obtained to vaporize the active substance, one of the ends of the footprint was lit with a match, checking (by smell and sight) that, as the heat source advanced along the footprint, the active substance was vaporizing.
