Problems solved by technology

However, due to the long-term exposure of composite materials to sunlight, fiber burrs will appear on the surface, and resin aging and crushing will occur in severe cases, which affects the safety of towers. Limited by material properties and manufacturing processes, the aging resistance of composite materials has not been resolved so far.

Abstract

The invention discloses a transmission line tower fluorocarbon coating having resistance to ultraviolet rays and ageing, and a preparation method thereof. The fluorocarbon coating comprises fluorocarbon resin, a color filler, a dilution solvent, an assistant and a curing agent. The transmission line composite material tower fluorocarbon coating has a scientific and reasonable ratio, and can be sprayed on the surface of a transmission line tower to obtain a fluorocarbon coating layer having resistance to ultraviolet and ageing. The normal temperature fluorocarbon coating has the following advantages: (1) the construction process is simple and does not need thermal chemical reaction curing, the coating can be directly sprayed at the construction site and is naturally cured during construction, and technologic requirements are very simple; 2) the normal temperature fluorocarbon coating has same performances, remarkably more simple and remarkably less construction cost than a high temperature fluorocarbon coating; and (3) the construction is convenient, the construction cost is significantly reduced, construction is not affected by the environment or the size of a substrate, and manpower and material resources in the construction process are reduced.

Description

technical field [0001] The invention relates to a coating, in particular to a fluorocarbon coating for transmission line towers with anti-ultraviolet and anti-aging properties and a preparation method thereof. Background technique [0002] The tower structure is an important support structure in infrastructure such as power transmission, communication, and road lighting, and its structural performance directly affects the safety, economy, and reliability of the line. Traditional wooden poles, concrete poles, steel pipe concrete poles, steel pipe poles and iron towers generally have problems such as high quality, easy cracking, short service life, difficult construction and maintenance, and are prone to various safety hazards. Composite towers have excellent insulation properties, corrosion resistance, mechanical properties and low maintenance costs, and can replace traditional towers in the construction of power transmission and distribution lines. However, due to the long-...
