Use cenosphere with titanium dioxide for aggregate, modified polymer emulsion is adhesive, and water is medium, adds aqueous promoter.Respectively
Embodiment products obtained therefrom is water solubility, nontoxic, is free of harmful organic volatile, and appearance is white or the sticky paste of canescence
Object forms a film bright and clean after dry, is used on most of clean, dry surfaces, all has preferable adhesive strength.It is producing and is making
Harmful waste and gas are not will produce in；Titanium dioxide and cenosphere can close-packed arrays, formed to sunlight
Total reflection makes coating that there is height to radiate, the characteristic of high reflection, can effectively reflect away 90% or more solar heat energy, build
Object surface only has a small amount of solar heat savings, while cenosphere being made full use of to have extremely low thermal coefficient, efficient heat
Barrier property has effectively obstructed the heat transfer of external wall savings to inside, has obstructed remaining 10% sunlight completely and produced
Raw heat can be not only used for hotter province building of southern summer, reflects solar thermal energy for summer, prevents building wall body from inhaling
It receives and stores a large amount of solar heat, and can be used for the insulation in the heat-insulated and winter of building in the north object summer, reach energy-efficient
Purpose, it can also be used to the reflecting heat insulation of petrochemical industry light oil tank.
