摘　　要：以聚酯改性羟基丙烯酸树脂为主要成膜物质研制了一种底面合一辊涂型风电叶片涂料,选用氟改性有机硅消泡剂和聚醚改性有机硅消泡剂复配能很好地消除辊涂时产生的气泡;选用有机硅流平剂和氟改性聚丙烯酸酯流平助剂复配可以达到优异的流平效果;采用气相二氧化硅和改性脲复配能消除风电叶片涂料的橘皮和立面流挂问题;消光粉和溶剂的选择对表面效果也有影响。Based on polyester modified hydroxyacrylic resin,a primer-topcoat-in-one formulation for roller applied wind turbine blade coatings was developed,which met the need of roller applied wind turbine blade coatings.The results showed that the combination of fluoro-silicone defoamer and polyether modified silicone defoamer could eliminate the bubbles produced by the roller application.The combination of fluoro-silicone and fluoro-polyacrylate could achieve an excellent leveling effect.The combination of fumed silica and modified urea could eliminate the problems of"orange peel"and sagging on the vertical surface of a wind turbine blade.The type of matting agents and solvents in the formulation also contributed an effect to the surface finish.
