Abstract

The invention discloses a composite high-temperature-resistant cable bridge, and coating technology, and belongs to the technical field of cable bridges. The composite high-temperature-resistant cablebridge comprises a bridge main body; the external surface of the bridge main body is coated with an internal high temperature resistance layer and an external anti-corrosion layer; the external anti-corrosion layer is prepared through coating of an epoxy coating, and the thickness ranges from 1 to 2mm; the internal high temperature resistance layer comprises, by weight, 55 to 65 parts of polycarbosilane, 4 to 9 parts of glass fiber, 9 to 11 parts of m-benzol unsaturated polyester resin, 20 to 25 parts of acrylic resin, 13 to 14 parts of alumina, 12 to 16 parts of iron oxide, 10 to 15 parts ofdioctyl phthalate, 5 to 9 parts of polyacrylamide, 3 to 5 parts of perlite, 2 to 4 parts of acetylene carbon black, and 4 to 7 parts of sodium bicarbonate. The composite high-temperature-resistant cable bridge possesses excellent corrosion resistance and high temperature resistance, and the service life of the composite high-temperature-resistant cable bridge is prolonged.

Description

technical field [0001] The invention relates to the technical field of cable bridges, in particular to a composite high temperature resistant cable bridge and a coating process. Background technique [0002] In the field of power engineering, high temperature resistant cable trays are widely used. Since most power equipment is exposed to direct sunlight for a long time, and a large amount of heat is emitted during the operation of the equipment, the heat dissipation performance and high temperature resistance of the bridge frame are highly required in actual use, and most of the existing bridge frames cannot meet the needs of use under extreme conditions. , especially the bridge material itself due to poor high temperature resistance, easy to damage and bring safety hazards to power equipment. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a composite high temperature resistant cable bridge, which includes...
