Problems solved by technology

A commonly used method at present is to use electric arc sprayed aluminum. The anti-slip coefficient of the electric arc sprayed aluminum layer is high, but the energy consumption of the electric arc sprayed aluminum construction process is high, and the porosity of the aluminum coating is high, and it is easy to rust after long-term storage, so Additional special protection is required
[0003] In the Chinese patent with the authorized announcement number CN201520941U, a composite protective coating structure for the friction surface of bridge bolts is disclosed. It is sealed by spraying a layer of inorganic zinc-rich anti-rust and anti-skid coating on the metal layer, which can ensure anti-skid transfer coefficient and long-lasting corrosion resistance, but the scheme is r

Description

technical field [0001] The invention relates to the field of water-based anti-corrosion materials, in particular to a water-based epoxy anti-corrosion coating and a preparation method thereof. Background technique [0002] With the rapid development of the national economy and the expansion of the scale of infrastructure construction, the problem of protective coating for many engineering projects has become an important topic in the field of anti-corrosion engineering. Especially the anti-corrosion coating of the friction surface of the bolted and welded beam connection parts of steel facilities such as ships and bridges needs to be protected by an anti-corrosion coating with excellent anti-rust and anti-skid performance. A commonly used method at present is to use electric arc sprayed aluminum. The anti-slip coefficient of the electric arc sprayed aluminum layer is high, but the energy consumption of the electric arc sprayed aluminum construction process is high, and the p...
