Abstract

The invention discloses a wind power blade repairing quick-drying finishing coat which consists of a coating part and a curing agent part, wherein the coating part consists of the following components in parts by weight: 30-60 parts of polyaspartic acid ester resin, 15-35 parts of paint, 1-5 parts of an anti-sinking agent, 0.5-3 parts of a dispersing agent, 1-3 parts of a defoaming agent, 0.2-2 parts of a flatting agent, 2-4 parts of a light stabilizing agent, 1-3 parts of an ultraviolet absorbent, 3-8 parts of extinction powder, 2-5 parts of a high-abrasion-resistance agent and 5-20 parts of an organic solvent; the curing agent part consists of a curing agent and an organic solvent. The coating of the wind power blade repairing quick-drying finishing coat is high in reaction speed; a coating film is thick; the construction period is shortened; under a condition of the same film thickness, the number of coating layers can be reduced; therefore, the construction efficiency of the coating is improved; the wind power blade repairing quick-drying finishing coat is suitable for a quick wind power blade repairing field.

Description

technical field [0001] The invention belongs to the field of coatings for wind power blades, in particular to a polyaspartate topcoat for repairing wind power blades and a preparation method thereof. Background technique [0002] With the increasing shortage of oil resources in the world, wind energy has gradually been paid attention to as a clean and renewable energy. The development and utilization of wind energy resources can not only find new alternative energy sources for the 21st century, but also benefit environmental protection. [0003] The development of my country's wind power industry has experienced a process from small to large and from slow to fast. From the successful development of a 1KW small-scale wind turbine prototype in the 1970s, to the national "Riding the Wind Plan" in 1998 opened the prelude to the localization of large-scale wind turbines; from 1986, my country's first wind farm was connected to the grid in Rongcheng, Shandong Province for power g...
