Description

Technical Field

[0001] The present invention relates to the technical field of materials engineering, and specifically, to a coating for a fire-fighting robot integrating painting, high temperature resistance and heat insulation, and a spraying method thereof. Background Art

[0002] With the development of urban construction, the hazards of fires are becoming greater and greater. At the same time, it has greatly increased the difficulty of fire fighting and rescue, threatening the lives of firefighters. Fire-fighting robots can enter the fire scene, explore the situation, open up roads and implement fire extinguishing, which is a great tool for fire fighting and rescue. However, the internal situation of the fire scene is complex, the fire is fierce, and the temperature is high. In case of special situations such as combustible gases, the temperature can reach above 1000 °C, which poses higher requirements for the overall thermal protection technology and surface painting of fire-fighting robots.

[0003] In the prior art, most of the surface paintings of fire-fighting robots and other fire-fighting equipment on the market still use ordinary organic paints. Organic paints have poor high-temperature resistance and will age, lose color, burn, powder and peel off at high temperatures. Subsequently, the surface appearance of the equipment is damaged and the steel plate matrix is exposed. Under the action of high temperature, water and air, the steel plate matrix is oxidized, affecting the appearance of the equipment and the mechanical properties of the steel plate.

[0004] Inorganic coatings have high high-temperature resistance, and some systems can resist 1500 - 1800 °C. However, ordinary inorganic coatings have poor toughness, insufficient adhesion strength to the metal matrix, and poor resistance to thermal cycling, which easily leads to cracking and peeling. There is an urgent need for a coating for a fire-fighting robot integrating painting, high temperature resistance and heat insulation to solve the above problems. Summary of the Invention
