Abstract

The invention relates to the technical field of chemical coatings, and particularly discloses a potlife-adjustable wind turbine blade coating and a preparation method thereof. The coating consists of components A and C, wherein the component A is prepared from the following raw materials in parts by weight: 20 to 40 parts of polyaspartic acid ester resin, 3 to 6.5 parts of liquid acrylonitrile butadiene rubber, 1.5 to 4 parts of a water removal agent, 2 to 12 parts of a reactive diluent, 0.4 to 2 parts of a wear-resistant agent and 34.8 to 74.9 parts of an auxiliary; the component C is prepared from the following raw materials in parts by weight: 93 to 99 parts of an isocyanate curing agent and 1 to 7 parts of an organic solvent. The potlife of the potlife-adjustable wind turbine blade coating is adjustable between 0.5 to 2.5 hours, the potlife-adjustable wind turbine blade coating has low glossiness, solid content capable of reaching over 80 percent, high flexibility, impact resistance, rub resistance, weather resistance and short construction period, and can be used as a primer and a topcoat for single-pass construction, and the long-term protection requirements of a wind turbine blade and the development trend of low coating VOC are met.

Description

technical field [0001] The embodiments of the present invention relate to the paint industry in the field of chemical industry, in particular to a wind power blade paint with adjustable pot life and a preparation method thereof. Background technique [0002] Wind energy is a green and non-polluting energy. With the gradual reduction of traditional petrochemical resource reserves and the increasing impact on the environment, the development and utilization of wind energy has grown rapidly. Wind power blades are one of the key core components of wind power generation devices. Most of the blades in the existing technology are made of epoxy glass fiber composite materials. The megawatt-level blades are close to 50 meters, and the larger ones can reach 80 meters. The maintenance cost is high. In addition, areas rich in wind energy are usually located in remote locations and have inconvenient transportation. Therefore, blade coatings require a long protection period, which can pro...
