Embodiment 1
[0018] Copper oxide and barium nitrate are fully mixed according to the mass ratio of copper oxide: barium nitrate = 4: 100 and then passed through a 90-mesh sieve for 3 to 4 times. See Table 1 for the data.
Embodiment 2
[0020] Cuprous oxide and barium nitrate are fully mixed according to the mass ratio of cuprous oxide: barium nitrate = 2: 100 and then passed through a 90-mesh sieve for 3 to 4 times, and the under-sieve is taken to test thermal decomposition performance and firecracker agent discharge performance. The obtained data are shown in Table 1.
Embodiment 3
[0022] Cobalt oxide and barium nitrate are fully mixed according to the mass ratio of cobalt oxide: barium nitrate = 3: 100, and then passed through a 90-mesh sieve for 3 to 4 times. See Table 1 for the data.

Abstract
The invention discloses an active agent for improving the reaction activity of a firework and firecracker oxidant barium nitrate, which is characterized by comprising a monomer active agent and a compound active agent, wherein the monomer active agent is any one of ferric oxide Fe2O3, stannic oxide SnO2, stannous oxide SnO, nickel oxide NiO, cobalt oxide CoO, cuprous oxide Cu2O and copper oxide CuO; and the compound active agent is any two of or a mixture of more than two of ferric oxide Fe2O3, stannic oxide SnO2, stannous oxide SnO, nickel oxide NiO, cobalt oxide CoO, cuprous oxide Cu2O and copper oxide CuO. Activated barium nitrate which is obtained by using the active agent and is used as a raw material has high safety when stored and transported.
Description
technical field [0001] The invention relates to a raw material of pyrotechnic powder, in particular to an active agent capable of effectively improving the reactivity of barium nitrate, an oxidant of firecrackers. Background technique [0002] At present, the safe production of the fireworks industry has become an issue of great concern to the society; the State Council has explicitly banned the use of highly sensitive potassium chlorate as the oxidant for fireworks in the fireworks industry in 2002 (General Office Guobanfa [2002] No. 52 document) . In order to provide the fireworks industry with cheap, environmentally friendly and safe fireworks oxidizers that can replace potassium chlorate, relevant professional technicians have carried out extensive exploration and research. Patent CN 1746141A proposes a formula-type safe oxidant with potassium perchlorate and barium nitrate as the main body; but because the reactivity of barium nitrate is far lower than that of traditio...
