Abstract

The invention discloses a protection finish paint for a wind power blade, which comprises a component A and a component B according to a mass ratio of 7-10:1-4, wherein the component A comprises 30-60 percent by mass of modified hydroxylated acrylic resin used as the varnish base, 0.1-0.5 percent by mass of defoaming agent, 0.1-0.5 percent by mass of foam-removing agent, 0.1-0.5 percent by mass of adhesive force promoting agent, 0.5-2 percent by mass of anti-ageing agent, 1-3 percent by mass of abrasion-resistant assistant, 3-8 percent by mass of delustering agent, 0.5-2 percent by mass of wetting dispersal agent, 0.5-2 percent by mass of thixotropic agent, 5-35 percent by mass of organic solvent I and 18-35 percent by mass of titanium white; and the component B comprises 70-95 percent by mass of curing agent and 5-30 percent by mass of organic solvent II. The invention also discloses a preparation method of the protection finish paint for the wind power blade.

Description

technical field [0001] The invention relates to a protective finish paint and a preparation method thereof, in particular to a protective finish paint for a blade of a wind power generator and a preparation method thereof. Background technique [0002] At present, the blades used in my country's wind power industry are mainly made of glass fiber reinforced epoxy resin. Although epoxy resin meets the mechanical performance requirements of wind power blades in all aspects, due to its poor weather resistance, the material will age and pulverize after being exposed to the outdoor environment for a long time after being irradiated by ultraviolet light. The service life of blades made of glass fiber reinforced epoxy resin is greatly shortened if the surface is not protected. [0003] In the field of protective coatings for wind turbine blades, the implementation of protective topcoats is mainly manifested in two aspects: resins and special additives. Most of the special additive...
