Abstract

The invention relates to a dark colour-system reflection-type outer wall thermal insulation coating and a preparation method thereof. A selected film forming material is an organosilicon modified styrene-acrylate emulsion, pigments are rutile-type titanium dioxide, iron oxide red, iron oxide black and medium chrome yellow, and filling comprises talcum powder, kaolin and triple superphosphate. The particle size range of the rutile-type titanium dioxide is determined to be 0.107mum-0.687mum when the reflectivity of the coating is higher, the particles are rectangular, and the coating is blended into brown. The coating contains 20-30 percent of organosilicon modified styrene-acrylate emulsion, 5-10 percent of rutile-type titanium dioxide, 1-5 percent of iron oxide red, iron oxide black and medium chrome yellow, 28-43 percent of talcum powder, kaolin and triple superphosphate, 5-8 percent of assistant and 20-35 percent of water. The coating has obvious thermal insulation effect, attractive and elegant appearance, scouring resistance, good weather fastness, simple production process, good disperse effect, lower cost and stable product performance; and the coating is a waterborne system, and therefore, the coating has the significance of environmental protection and energy saving.

Description

technical field [0001] The invention relates to an exterior wall heat-insulating coating and a preparation method thereof, in particular to a dark-color reflective exterior-wall heat-insulation coating and a preparation method thereof. Background technique [0002] Energy efficiency in buildings is the primary aspect to improve the efficiency of energy utilization in society. If the exterior wall coating has thermal insulation performance, it will provide a more convenient and economical way for building energy conservation. Most of the reflective heat-insulating coatings currently developed are made by adding substances with heat-insulating radiation effects. For example, in the "reflective and heat-insulating coating and its production method" provided by the invention patent CN200910085967.3, 2-8% of ceramic hollow microspheres and 2-3% of infrared powder are added. The prepared coating has a strong reflection and barrier effect on solar radiation heat, and can effective...
