Abstract
The invention discloses a high-temperature resistant coating for a bridge. The high-temperature resistant coating for the bridge comprises the raw materials of brown aluminium oxide, black silicon carbide, sodium silicate, melamine polyphosphate, pentaerythritol, 1,2-dimethyl-5-acetoxyl group-1H-indole-3-carboxylic acid ethyl ester, aluminum silicate fibers, hollow microspheres, silicon dioxide, antibacterial preservatives, film forming auxiliaries, water-based polyurethane resin, acrylic ester, tung oil, titanium dioxide, polyvinyl alcohol, light calcium carbonate, talcum powder, gypsum powder, titanium dioxide, silane compounds, guar gum, fluororesin, water-based epoxy modified resin, Ni, Zn, water and the like. Due to the fact that the high-temperature resistant coating for the bridge contains the components such as Ni and Zn, the high-temperature resistant coating for the bridge has the high-temperature resistant and anti-corrosion properties and meets the coating requirements of various occasions; in addition, the high-temperature resistant coating for the bridge does not contain toxic organic solvent, is free of pollution and has the advantages that the paint surface cannot crack, anti-aging is achieved, and the adhesive force is high.
Description
technical field [0001] The invention relates to a high-temperature-resistant coating for a bridge frame and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, supporting arms and installation accessories. It can be erected independently, or attached to various buildings (structures) and pipe gallery supports, reflecting the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized and installed in buildings. If the bridge frame in the open air is near the sea or belongs to the corrosion area, the material must have the physical characteristics of anti-corrosion, moisture resistance, good adhesion, and high impact resistance. [0003] The surface of the bridge frame and its supports and hangers shall be painted w...
