A kind of aviation water-based color smoke pulling agent and preparation method thereof

Abstract

The invention relates to the technical field of aviation colored smoke pulling agent, in particular to a water-based colored smoke pulling agent for aviation and a preparation method thereof. The main components of the water-based color smoke pulling agent are diethylene glycol and coloring dyes. The present invention changes oily fuming components into water-based fuming components, changes coloring dyes into water-based coloring dyes, reduces the types and amounts of various additives used, and selects special water-based coloring components. It solves the problems of difficult cleaning and lack of smoke color in traditional colored smoke-pulling agents, and achieves a safe, environmentally friendly and non-toxic use effect, and also broadens the scope of application of colored smoke-pulling agents to models, and can be applied to multiple It overcomes the shortcomings of the traditional third-generation oil-based color smoke puller, and successfully obtained a fourth-generation aviation color smoke puller that is convenient to clean, safe, environmentally friendly and non-toxic, and suitable for multiple models.

Description

technical field [0001] The invention relates to the technical field of aviation colored smoke extractor, in particular to an aviation water-based colored smoke extractor and a preparation method thereof. Background technique [0002] In the air show, the smoking show has become one of the most important performance items. The smoke belt can record the attitude, trajectory and mutual positional relationship of the aircraft flying in the air, which can increase the appreciation and artistry of the air show. Technology All aerobatic performance teams will perform smoke-pulling performances during the performance, and there are only a handful in the field of colored cigarettes, and the technology is not perfect. Insufficient and defective, the color smoker is a powdery dye, soluble in water-based solvents, not thick or crystallized at low temperature, completely sublimated at high temperature, used for air performances, and instantly completely sublimated together with exhaust g...

Problems solved by technology

[0003] Nowadays, most of them use solid colored smoke bombs and third-generation colored smoke-pulling agents. Traditional solid colored smoke for fireworks and firecrackers has the following defects: the effect of gathering smoke is short, the color effect is light, and it cannot be controlled after ignition.

And it contains certain dangerous substances such as sulfuric anhydride, potassium nitrate, etc., which may be flammable and explosive during transportation and storage

Now after improvement, the third generation of oily liquid smoke pulling agent has entered the market one after another. The third generation of oily liquid color smoke is an oily color smoke pulling agent, which has the following defects: due to the determined characteristics of oily smoke components, it is easy to form a supersaturated solution As a result, the solubility of the dye is reduced, and it is difficult to clean the skin and the fuselage if it is stained. Because the color is relatively light, it is necessary to equip a telescopic nozzle such as the telescopic smoke agent nozzle pointed out in the Chinese patent (CN201721463641.6) to adapt to the different colors of the color smoke agent. Different temperature requirements, and because of the corrosion and clogging effect on the fuselage and nozzle, it is necessary to equip the anti-corrosion smoke pulling agent nozzle pointed out in the Chinese patent (CN201721463657.7). Most of the smoke pipes are pipes and nozzles made of ordinary materials, which cannot fully meet the environmental requirements for the use of oil-based color smoke agents. Because the models are relatively single, the customer experience is not strong

[0004] Chinese patent (CN110627597A) discloses a kind of aviation color smoke pulling agent and its preparation method, and specifically discloses the following components: smoke component 20-50%, coloring component 24-40%, viscosity regulator 24-40% %, dispersant 1-3%, pour point depressant 0-0.5%, flame retardant 0-1%, and specifically pointed out that the fuming component is an aliphatic hydrocarbon solvent, that is, an oily color smoke puller, the The color smoke pulling agent is the third generation oily color smoke pulling agent. Because it uses aliphatic hydrocarbon oily fuming solvent, it still has the shortcomings of the existing third generation oily color smoke pulling agent, that is, there is contamination to the skin and The fuselage is difficult to clean, long-term use will cause corrosion to the fuselage and ordinary nozzles, the color is relatively light, and the model is relatively single, etc.
