NOVELTY - Thixotrope is prepared by (A) preparing component A, (B) preparing component B, and (C) mixing two components at wt. ratio of 2:1. The step (A) comprises kneading epoxy resin, hydroxy blocking polyurethane flexibilizer for special polyurethane, diluting agent, glass fiber, thixotropic agent, thixotropic agent and auxiliary agent. The step (B) comprises kneading polyamide curing agent, flexibilizing curing agent, glass fiber, thixotropic agent and thixotropic agent assistant. The epoxy resin is phenol A epoxy resin E44 and/or bisphenol A epoxy resin E51.    USE - Method for preparation of thixotrope for large power wind power blade (claimed).    ADVANTAGE - The prepared thixotrope has high-low temperature impact resistance, and has prolonged adaptive phase.    DETAILED DESCRIPTION - A thixotrope is prepared by (A) preparing component A, (B) preparing component B, and (C) mixing two components at wt. ratio of 2:1. The step (A) comprises providing raw materials comprising (pts. wt.) epoxy resin (60-80), hydroxy blocking polyurethane flexibilizer for special polyurethane (5-10), diluting agent (5-10), glass fiber (0.1-0.5), thixotropic agent (15-25), thixotropic agent (5-10) and auxiliary agent (0.1-0.5); and pouring raw materials into kneading machine with heating device, mixing at normal pressure and 60 degrees C for 30 minutes, milling and dispersing by three-roller mill, and obtaining component A. The hydroxy blocking polyurethane flexibilizer for special polyurethane is prepared by adding polyether dihydric alcohol (100) and toluene diisocyanate (TDI, 7.2) into flask, stirring at normal pressure and 60 degrees C, stirring, and reacting for 30 minutes; heating to 80 degrees C, stirring, reacting for 3-5 hours, reaching molecular weight to 2500-3500 Dalton; heating to 90 degrees C, adding tetramethylbenzene dimethylene diisocyanate, continuously stirring, and reacting for 6-8 hours; and heating to 120 degrees C, stirring for 4-6 hours, obtaining desired flexibilizer having molecular weight of 800-3000 Daltons. The step (B) comprises raw materials comprising polyamide curing agent (40-60), flexibilizing curing agent (10-30), glass fiber (5-15), thixotropic agent (5-15) and thixotropic agent assistant (0.1-0.5); and adding raw materials into kneading machine with heating device, mixing at normal pressure and 60 degrees C for 30 minutes, milling and dispersing by three-roller mill, and obtaining thixotrope B component. The flexibilizing curing agent is prepared by stirring p-benzene dimethylamine (100) and polypropylene glycol diglycidyl ether (180-220) into flask, stirring at room temperature and normal pressure for 24 hours, heating to 70 degrees C, stirring for 6 hours, and obtaining the curing agent. The epoxy resin is phenol A epoxy resin E44 and/or bisphenol A epoxy resin E51. Diluting agent is glycol diglycidyl ether. Crosslinking agent is silane crosslinking agent KH-560 or KH-570. Thixotropic agent is silica and/or organobentonite. Thixotropic agent assistant is methanol, water, glycerin or ethanol. Polyamide curing agent is polyamide curing agent 650 or polyamide curing agent 651. An INDEPENDENT CLAIM is included for the thixotrope prepared by above method.
