Preparation and Performance Study of Reflection Heat Preservation Insulation Coating
The influence of film forming matter to heat preservation insulation coating reflectivity was studied. Organosilicon modified styrene-acrylic emulsion was selected as film forming matter through the infrared spectrum test. The influence of several kinds of pigment and filler to reflectivity was studied by orthogonal experimental design . Importance of factors from large to small in turn is: Rutile titanium dioxide> Kaolin> expanded perlite、hollow glass microsphere> iron oxide red, and the formula of pigment and filler was determined .The influence of rutile titanium dioxide to reflectivity was studied, the reflectivity of coating is superior when rutile titanium dioxide grain size is in the range between 0.130 m and 0.136 m. Film thickness has certain influence to reflectivity ,when the thickness is 0.062cm, the reflectivity of coating reaches the highest,is 73.28%.
