Description

technical field [0001] The invention relates to the technical field of iron and steel, in particular to a coating composite material and its application. Background technique [0002] CN200910190689.8 discloses a method for improving the conductivity of dacromet coating and a metal piece with high conductivity dacromet coating, adding metallic silver particles or containing metallic silver to the dacromet solution coated with metal substrate The aqueous conductive silver paste of particles, the diameter of the metal silver particles is 1-20 μm. The invention provides a method that not only ensures the excellent corrosion resistance of the coating, but also improves the conductivity of the dacromet coating on the metal substrate. However, the use of silver leads to high costs. Contents of the invention [0003] In view of the above-mentioned technical defects, the object of the present invention is to provide a coating composite material and its application. The coating c...
