Problems solved by technology

If the heat dissipation of the building is not good, it will cause the heat to accumulate and conduct to the room, causing the indoor temperature to rise and the energy consumption of air conditioners and other equipment to increase.
If the temperature of industrial facilities such as petrochemical storage tanks is too high, it is easy to explode and cause major hazards
[0003] In addition, the heat dissipation coatings currently on the market are all solvent-based products, which use organic solvents, which are not in line with the current trend of environmental protection in my country

Abstract

The invention discloses a heat-dissipation coating and a preparation method thereof. The heat-dissipation coating comprises the following raw materials in parts by weight: 20-35 parts of polymer matrix emulsion, 0.5-1 part of a coalescing agent, 2-10 parts of infrared radiation powder, 2-10 parts of a powder dispersing agent, 15-20 parts of pigments and fillers, 5-10 parts of high thermal conductivity filler, 0.8-1.5 parts of a sagging inhibitor, 0.4-0.8 part of a defoaming agent, 0.3-1.2 parts of a coating dispersant and 20-50 parts of water. The infrared radiation powder and the high thermalconductivity filler are separately added in the coating, a heat conduction effect of a coating layer can be enhanced, furthermore, heat can be rapidly radiated into the air space at an infrared wavelength of 8-13.5 mu m, the temperatures of the surface and the inside of the coating layer are reduced effectively, and a heat-dissipation and cooling effect is obvious; and water is used as a solvent,and is economical and environmentally friendly; and a preparation process of the heat-dissipation coating is simple, the production cost is low, and thus, the heat-dissipation coating is suitable forbatched production.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a heat-dissipating coating and a preparation method thereof. Background technique [0002] The heat dissipation of mechanical equipment and buildings has always been a hot research topic. Overheating of the engine will cause the air charge coefficient to drop and the fuel to burn insufficiently. In addition, overheating of parts will reduce the mechanical properties of materials and generate thermal stress, which will eventually lead to deformation of parts, cracks and affect the normal movement gap between parts, which will increase the friction resistance between parts and aggravate wear. Especially the movement between the piston ring and the cylinder wall, when the friction is severe, ablation, sticking, engine stalling or cylinder scuffing will occur. And if the temperature is too high, the lubricating oil will deteriorate and coke, lose its lubricating performance, and f...
