Abstract

The invention provides a flexible wear-resistant armor clamp heavy-duty paint and a preparation method thereof. The preparation method of the heavy-duty paint comprises the following steps: adding 23-26 wt% of isophorone and 34-35 wt% of propylene glycol methyl ether acetate into a dispersion device, stirring uniformly, adding 0.15-0.32% of dispersing agent, 0.15-0.32% of defoaming agent and 0.15-0.32% of leveling agent, continuing stirring uniformly, adding 23-26% of polyester organic silicon resin, dispersing uniformly, adding 10.5-13.8% of silicon carbide, 1.2-1.3% of molybdenum dioxide and 1.5-3.2% of barium petroleum sulfonate, continuing stirring and dispersing uniformly, grinding in a cone mill until the particle size is 70-90 micrometers, finally adding 1.1-2.6% of silica white, dispersing uniformly, and filtering to obtain a component A; and before use, uniformly mixing the component A and an inorganic silicon resin in a mass ratio of 1:(1.4-1.6). The heavy-duty paint has the advantages of simple preparation process, high efficiency, long and enduring anticorrosive effect and excellent wear resistance.

Description

technical field [0001] The invention relates to a metal anticorrosion coating, in particular to a flexible and wear-resistant heavy-duty anticorrosion coating for metalware and a preparation method thereof. Background technique [0002] With the increasing scale of the country's power grid construction, the corrosion of transmission lines has also received more and more attention and attention. The corrosion environment of transmission line fittings mainly includes atmospheric corrosion, water corrosion and soil corrosion. Corrosion damage greatly shortens the life of transmission lines, especially for transmission lines in corrosive environments, which often cannot reach their expected design life. In the design, construction and operation and maintenance of power transmission lines in my country, necessary protective measures have been taken for the transmission metal tools in view of the atmospheric environment and water and soil environment in the areas where the transm...
