Description

technical field [0001] The invention relates to a heat-insulating coating, in particular to a nano-titanium dioxide styrene-acrylic emulsion composite 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 the sun to insulate and cool the roof, save energy and reduce consumption. It has heat insulation, waterproof, antirust, anticorrosion , short construction period and quick effect, fully replace the water spray system, thermal insulation cotton, foam sponge, interlayer iron sheet, etc. There are three main types of thermal insulation coatings in terms of characteristics and principles, insulating conductive thermal insulation coatings, reflective thermal insulation coatings and radiant heat insulation coatings. In addition to the above three types of heat insulation coatings, a heat insu...
