High strength and energy saving flexible bridge frame

Abstract

The invention discloses a high strength and energy saving flexible bridge frame, which includes a bridge frame shell. The bridge frame shell is externally provided with a protective coating formed by paint, and the paint is composed of polyurethane, epoxy resin, acrylic resin, polytetrafluoroethylene, polyethylene glycol, butanediol, linseed oil, alumina, ceramic powder, silicon powder, cerium oxide, a solvent, a curing agent, aluminum potassium sulfate and sodium fluosilicate. Due to adoption of polyurethane, epoxy resin, acrylic resin and polytetrafluoroethylene by the invention, the high crosslinking density paint can be formed through mutual synergistic effects of the resins. The paint has extremely high surface hardness, excellent flexibility, bending resistance and flexibility, and excellent physical and mechanical properties, thus being able to avoid stress concentration. Therefore, the film formed by the paint has very good tensile strength, tear strength and stone impact resistance, thereby ensuring the service life of the bridge frame.

Description

technical field [0001] The invention relates to a bridge frame, in particular to a high-strength and energy-saving flexible bridge ceramic coating, which belongs to the technical field of power transmission and distribution equipment. Background technique [0002] A bridge is a bracket that supports and places cables. With the development of industry, bridges are used more and more widely. There are also applications in most harsh environments, such as more corrosive environments. Since it works in a harsh environment for a long time, it has high requirements for corrosion resistance, wear resistance, weather resistance, ultraviolet resistance, and anti-icing performance. Therefore, it must be effectively protected. [0003] At present, bridges generally use imported polyurethane coatings, epoxy resin coatings, or imported gel coats to protect the bridge body. However, due to the harsh environment in which the bridges are used, the existing gel coats or coatings have poor ...

AI Technical Summary

Problems solved by technology

[0003] At present, bridges generally use imported polyurethane coatings, epoxy resin coatings, or imported gel coats to protect the bridge body. However, due to the harsh environment in which the bridges are used, the existing gel coats or coatings have poor wind and sand resistance and cannot solve the problem of rain and snow. The impact and damage of wind and sand, hail and wind and sand on the surface of the bridge often cause the wear of the bridge, thus affecting the service life of the bridge

[0004] Traditionally used anti-corrosion coatings only have anti-corrosion properties and cannot meet the needs of anti-corrosion, wear-resistant, and impact-resistant properties. During coating construction, they are divided into primers and top coats, which are labor-intensive and inconvenient for construction. Many harmful volatile solvents are likely to cause environmental pollution and harm to construction workers
