Problems solved by technology

[0003] The raw materials of the currently developed black fuming agent are toxic, carcinogenic (such as anthracene) or substances with pungent odors (such as naphthalene). The use of these raw materials has greatly affected the health of officers and soldiers participating in training simulation It is extremely harmful to the body to be in such a training environment for a long time

Embodiment 1

[0022] 1), accurately weigh 3g of red dye, 4g of yellow dye, and 12g of blue dye, and mix thoroughly to make black dye, and prepare black dye with potassium chlorate, sucrose and ammonium oxalate according to 4.5:3:2:0.5 (mass than) accurately weighed, and evenly mixed to make 30g of black fuming agent, filled into the discharge shell, inserted lead wire and sealed, and ignited to discharge.

[0023] Test the color purity and dye toxicity when burning with the method shown in Table 1, and Table 2 is the test results.

[0024] The results show that its color purity is more than 95%. After continuous observation for 5 days and nights (120 hours), the physiological condition of the rats injected with the dye has no obvious change.

[0025] Table 1 Test method

[0026]

Embodiment 2

[0027] Embodiment 2: Accurately weigh 3 g of red dye, 4 g of yellow dye, and 10 g of blue dye to make black dye;

[0028] The composite material obtained is used as a dyestuff, and according to the preparation process of the color fuming agent, the composite dyestuff and potassium chlorate, sucrose and ammonium oxalate are accurately weighed according to 4.5:3:2:0.5 (mass ratio), and uniformly mixed to make 30g The black fuming agent is filled into the discharge casing, the lead wire is inserted and sealed, and then ignited and discharged. Test the color purity and dye toxicity when burning with the method shown in Table 1, and Table 2 is the test results. The results show that its color purity is more than 92%. After continuous observation for 5 days and nights (120 hours), the physiological condition of the rats injected with the dye has no obvious change.

Embodiment 3

[0029] Embodiment 3: Accurately weigh 4 g of red dye and 10 g of green dye, and fully mix to obtain black dye;

[0030] Accurately weigh the obtained black dye and potassium chlorate, sucrose and ammonium oxalate according to 4.5:3:2:0.5 (mass ratio), and mix uniformly to make 30g of black fuming agent, fill it into the discharge shell, insert Lead and seal, ignite and set off. Test the color purity and dye toxicity when burning with the method shown in Table 1, and Table 2 is the test results. The result shows that its color purity is more than or equal to 93%. After continuous observation for 5 days and nights (120 hours), there is no obvious change in the physiological condition of the rats injected with the dye.

Abstract

The invention discloses a black smoke agent and a preparation method thereof. The black smoke agent comprises the following components in percentage by mass: 35-46% of black dye, 25-35% of oxidant, 15-25% of combustible agent and 1-8% of ammonium oxalate. The preparation method comprises the following steps: 1) preparing black dye; 2) uniformly mixing the black dye, the oxidant, the combustible agent and the ammonium oxalate to obtain a mixture; and 3) filtering the mixture obtained in the step 2), sealing and packaging to obtain the black smoke agent. The black smoke agent disclosed by the invention can be applied to ventilation test, leakage check of a sealed container and training simulation. The black smoke agent disclosed by the invention is nontoxic and environmentally friendly; the dye is not decomposed, pollutants or side effects are avoided, and the colormetric purity is high; and the black smoke agent is suitable for batch production.

Description

technical field [0001] The invention relates to the field of preparation of fuming agents, in particular to a black fuming agent and a preparation method thereof. Background technique [0002] In the military, the black smoke agent is mainly used for training simulation, shielding interference, and transmitting signals and indicating targets during the day. In the civil society, it is mainly used for film and television effects and entertainment viewing. It forms a special smoke effect when it is set off, giving people a "beautiful" "Enjoyment. [0003] The raw materials of the currently developed black fuming agent are toxic, carcinogenic (such as anthracene) or substances with pungent odors (such as naphthalene). The use of these raw materials has greatly affected the health of officers and soldiers participating in training simulation It is extremely harmful to the body to be in such a training environment for a long time.
