Abstract
The invention discloses a nanometer TiO for a fan blade2The modified fluorocarbon coating comprises a first component and a second component, wherein the first component is prepared from the following raw materials in parts by weight: 30-75 parts of fluorocarbon resin, 1-8 parts of film-forming assistant, 1-3 parts of silane coupling agent, 1-3 parts of isopropanol, 1-2 parts of ultraviolet absorber, 0.5-1.5 parts of bentonite, 0.1-1.5 parts of flatting agent, and nano TiO20.5-1 part of defoaming agent, 0.1-1 part of dispersing agent and 15-25 parts of water; the second component comprises a curing agent; wherein, the nanometer TiO2The mass ratio of the first component to the second component in the modified fluorocarbon coating is 6-16: 1. the invention is prepared by mixing nano TiO2Dispersed in fluorocarbon resin, not only can improve the weather resistance and adhesive force of the coating, but also can enable the obtained coating to be capable of degrading organic pollutants by photocatalysis, therefore, the coating is coated with the coating of the inventionThe coated blade has the advantages of freezing resistance, wear resistance, weather resistance, ultraviolet resistance and the like.
Description
Technical Field
The invention belongs to the technical field of fluorocarbon coatings, and particularly relates to nano TiO for fan blades2Modified fluorocarbon coating and preparation method thereof.
Background
The wind power blade is subjected to ultraviolet irradiation, strong wind, erosion of seawater and salt-containing humid air, and striking of sand and stones. The height of the blades of the large-scale fan is mostly more than 50m, so that the blades are difficult to repair, and the cost is high. The service life of the common blade coating is short, and the phenomena of peeling and falling off of a paint film on the windward side of the blade can occur in 3-5 years of operation.
As the fluorocarbon coating has natural and more advantageous properties, the service life of a paint film is also higher and can reach the protection life of more than 10 besides higher weather resistance and corrosion resistance. The adhesive force of the fluorocarbon finish paint is relatively good, and the paint film has self-cleaning force which is not possessed by other anticorrosive finish paints, namely, dust on the surface can be completely cleaned away only by rainwater and the like, so that the cleanness of the paint film surface is achieved.
At present, various climatic conditions of the blades are severe in the actual operation process, the blades are generally eroded by wind and sand in the northern area and a large number of algae plants are attached to the blade parts in the southern area, and if the surfaces of the blades cannot be cleaned and sterilized in time, a large number of oil solutions and stains on the surfaces are accumulated, and a large number of organic matters are propagated, so that the aging of blade coatings is accelerated, and the service life of the blades is greatly shortened.
