NOVELTY - Wind power blade coating comprises a gel coat and a toluene diisocyanate (TDI) adduct, where every 100 parts of gel coat comprises e.g. elastic acrylic acid, elastic polyester, gray titanium dioxide, titanium dioxide, BYK-160 (RTM: Wetting and dispersing additive for solvent-borne automotive coatings), and BYK-358 (RTM: Solution of a polyacrylate) leveling agent. The TDI adduct is synthesized by the material, where every 100 parts of the material comprises e.g. trimethylolpropane, ethyl acetate, propylene glycol methyl ether acetate and antioxidant B-900.    USE - Used as a wind power blade coating.    ADVANTAGE - The wind power blade coating protects the rotor blade and provides long service life.    DETAILED DESCRIPTION - Wind power blade coating comprises a gel coat and a toluene diisocyanate (TDI) adduct according to the weight ratio of 2:1, where every 100 parts of gel coat comprises (in parts by wt.) elastic acrylic acid (25-35), elastic polyester (40-50), gray titanium dioxide (5-10), titanium dioxide (10-20), BYK-160 (RTM: Wetting and dispersing additive for solvent-borne automotive coatings) (0.1-2), BYK-358 (RTM: Solution of a polyacrylate) leveling agent (0.1-0.5), 5500 antifoaming agent (0.1-0.5) and propylene glycol methyl ether acetate (1-5). The TDI adduct is synthesized by the material, where every 100 parts of the material comprises (in parts by wt.) trimethylolpropane (15-20), ethyl acetate (1-5), propylene glycol methyl ether acetate (5-10), antioxidant B-900 (0-1), TDI (60-70), trimethylbenzene (1-5) and dehydrated propylene glycol methyl propyl acetate (5-10). The synthesis of TDI adduct comprises (i) mixing trimethylolpropane, ethyl acetate and antioxidant B-900, warming and dehydrating, adding propylene glycol methyl ether acetate, cooling the mixture to obtain the first mixed solution, dividing the first mixed solution to four equal parts, forming a first component, a second component, a third component and a fourth component, (ii) mixing TDI and trimethylbenzene, forming a second mixed solution, adding the first component, second component, third component, fourth component and dehydrated propylene glycol methyl propyl acetate at 25 degrees C for every 10-15 minutes to obtain a third mixed solution, and (iii) stirring the third mixed solution, maintaining the temperature primarily and secondarily, cooling and filtering the product to obtain the product.
