    Abstract：The influence of the key components such as polymer emulsion，heat insulation powder and zinc oxide on the metal roof waterproof coating is analyzed in detail. And test the tensile performance，low temperature bending properties，water absorption，stain resistance，heat insulation and other key indicators. The results show that the ultraviolet crosslinking acrylic emulsion and silicone rubber emulsion composites film was good for tensile property and stain resistance. Adding nano rectorite powder，six potassium titanate whisker and NiFe2O4 compound was beneficial to heat insulation for coating，adding zinc oxide coatings was beneficial to tensile strength，water absorption，and stain resistance.
