Abstract

The invention relates to a preparation method of a special salt spray resistance epoxy resin paint for a wind power blade and belongs to the technical field of coatings. The preparation method comprises the following steps: taking epoxy resin, acrylic resin, amino resin, rosin modified maleic acid resin, polystyrene latex, dimethylolpropionic acid, methyl methacrylate, tert-butyl perbenzoate, polyethylene wax, alcohol nitrocotton, butyl acetate and ethylene glycol butyl ether for uniformly mixing in a mixer; then adding a thickener and a dispersant and uniformly mixing in the mixer;adding a nonionic surfactant, a pigment and packing, uniformly mixing in the mixer, grinding to the fineness of below 20mum and packaging. The epoxy resin paint provided by the invention has good compatibility to the wind power blade made of an epoxy resin material, has a high adhesive force which can reach 1 grade, has good salt spray corrosion resistance and is suitable for coating the marine wind power blade.

Description

technical field [0001] The invention relates to a preparation method of epoxy resin paint, in particular to an epoxy resin paint with salt spray resistance for wind power blades, which belongs to the technical field of coatings. Background technique [0002] As we all know, due to the pressure of environmental protection and the impact of global climate change, countries around the world are vigorously developing renewable energy. Wind power has developed rapidly in recent years. According to the statistics of installed capacity of wind power in the world by Danish BTM Consulting Company: 28GW (28.19 million kW) was newly added in 2008, accumulatively exceeding 122GW (about 120 million kW). In 2009, 38GW (38.1 million kW) was newly added, and the cumulative total exceeded 160GW (about 160 million kW). Due to the limited land in Europe and the United Kingdom, it is difficult to develop large-scale wind power on land. They chose to develop offshore and carried out technical ...
