Description

technical field [0001] The invention relates to a coating, in particular to a water-based metal anti-corrosion, anti-rust and heat-insulating coating and a preparation method thereof. Background technique [0002] "Heat insulation coating": refers to a functional water-based coating developed in recent years that blocks, reflects, and radiates near-infrared heat from sunlight, which can insulate and cool roofs, save energy and reduce consumption. It has the characteristics of heat insulation, waterproof, anti-rust, anti-corrosion, short construction period, and quick results. It completely replaces the water spray system, thermal insulation cotton, foam sponge, interlayer iron sheet, etc. There are three main classifications of thermal insulation coatings in terms of characteristics and principles, insulating conductive thermal insulation coatings, reflective thermal insulation coatings and radiation thermal insulation coatings. In addition to the above three types of therm...
