Abstract
The present invention discloses a static-conducting rare earth modified waterborne chlorosulfonated polyethylene anticorrosive coating and a preparation method thereof. The coating is characterized by being prepared from the following raw materials in parts by weight: 50-60 parts of chlorosulfonated polyethylene emulsion, 3-6 parts of sodium dodecyl sulfate, 2-4 parts of lanthanum oxide, 20-30 parts of nitric acid solution, 3-5 parts of talc, 6-9 parts of ammonium bicarbonate solution, 3-5 parts of titanium dioxide, 5-10 parts of static-conducting graphite, 3-6 parts of waterborne epoxy resins, 3-6 parts of polyacrylic acids and 5-10 parts of a silane coupling agent KH560. The talc is combined with the rare earth compounds, which improves the corrosion resistance, aging resistance, abrasion resistance and glossiness of the coating. The static-conducting graphite is added into the coating, so that the coating has excellent static-conducting and anti-electromagnetic interference performances, and is suitable for the coating of a variety of equipment.
