When the vehicle normally runs, the whole vehicle is subjected to heat insulation protection, and good heat insulation and sealing measures can protect air conditioner in the vehicle so as to exert the functions of reducing energy consumption, reducing heat loss, improving comfort of passengers and improving running economy. The added nano ceramic powder greatly improves the fire resistance of the coating. When a fire disaster occurs, the heat diffusion can be delayed, the flame can be prevented from continuously burning, and the time for passengers to escape is prolonged.
The invention discloses a preparation method of an aerogel fireproof heat-insulation coating, which is formed by compounding aerogel powder, resin emulsion, other coating additives and fillers. The aerogel isA nano-porous material with a three-dimensional network structure has a controllable structure. The density of the aerogel is 3-500 mg/cm3The porous silicon carbide is the lightest solid material in the world at present, the porosity is 80-99.8%, the pore diameter is 2-50 nm, and the specific surface area is as high as 1000m2(ii) in terms of/g. Due to the unique nano-porous structure of the aerogel, the thermal conductivity coefficient of the aerogel is extremely low, and the thermal conductivity coefficient can reach 0.017W/(m.K) at the lowest under normal temperature.
The heat transfer is divided into 3 ways of heat conduction, heat convection and heat radiation. The aerogel can effectively isolate heat transfer aiming at the synergistic effect of the three heat transfer modes, and has excellent heat insulation performance.
1. In the aspect of heat conduction, heat is transferred along the aerogel framework, and due to the fact that a large number of nano pores exist in the aerogel structure, channels for heat transfer are increased to a great extent, energy is continuously consumed in the process of transferring the heat along nearly infinite channels, and heat conductivity is low. Meanwhile, due to the existence of the expanded ceramic film layer, the formed air layer further obstructs the heat transfer.
2. In the aspect of thermal convection, the internal pores of the aerogel are 2-50 nm and smaller than the average free path of gas molecule movement of 70nm, so that the gas molecules in the aerogel can not form convection, and the heat conducted by the thermal convection is very small.
3. In terms of heat radiation, due to the presence of a large number of pores in the aerogel structure, these pore walls act as "infinite sunscreens" reducing to a large extent the heat transfer of the heat radiation, the heat transfer by which is also quite low. And the aerogel is an inorganic material, so that the aerogel has the functions of non-combustion and flame retardance.
The novel coating is prepared by utilizing the characteristics of the aerogel, the nano ceramic powder is added into the coating, the nano ceramic powder in the coating is ceramized after being heated, an expanded ceramic film is formed on the surface of a base material, an air layer is arranged between the film and the base material, the flame is isolated from contacting the surface of a vehicle metal material product, and the heat is prevented from being transferred to the metal surface by means of the low heat conductivity coefficient characteristic of the aerogel in the coating. Compared with the expanded carbon layer of the traditional coating, the expanded ceramic film of the coating has high strength and long continuous protection action time in flame, can ensure that the heat transfer of metal parts in a vehicle is reduced during normal use, and has good barrier action on the flame during extreme fire accidents, thereby further enhancing the fire resistance of the coating.
