Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of smoke oil preparation, in particular to a high-stability black non-toxic smoke oil and a preparation method thereof. BACKGROUND

[0002] When an aircraft catches fire, there will be a situation of sky-high fire, smoke diffusion and low visibility. At this time, the fire scene is a great psychological test for fire fighters and rescue personnel. Therefore, real fire training can effectively improve the psychological quality of trainees when facing real fires, enhance the aircraft fire fighting and rescue combat skills, and improve the fire fighting and rescue skills and professional quality, so as to ensure the life safety of training fire fighters and emergency rescue personnel in the aircraft.

[0003] However, the fuel used for real fire training is seriously wasted, and the size of the flame and the amount of smoke generated are limited, which still has some gaps with the real fire scene, and cannot form thick gray smoke with low visibility. At this time, if the flame is matched with thick gray smoke or black smoke, a better fire scene can be formed, and a large amount of fuel can be saved. After forming a controllable smoke point, feedback can be given in time according to the fire development and the fire fighting operation of the fire fighter, forming a fire scene evolution and a fire fighting process training.

[0004] Currently, the stage smoke commercially used uses glycerol or ethylene glycol as the main raw material to form white smoke. Although the smoke oil prepared by ethylene glycol has good smoke effect, it is toxic, and the smoke maintaining time is short. Although the smoke oil prepared by glycerol is non-toxic, the smoke effect is not good. More importantly, neither of the two smoke oils can provide black smoke.

[0005] However, black or gray smoke is generated during the fire process. Therefore, a more realistic real fire training platform can be provided, a better fire scene can be formed by using thick smoke to match the flame, a controllable smoke point can be formed, feedback can be given in time according to the fire development and the fire fighting operation of the fire fighter, a fire scene evolution can be formed, and a fire fighting process training can be formed.

[0006] Therefore, it is of great significance to invent a black, non-toxic and long-maintaining-time smoke oil. SUMMARY
