Zusammenfassung:	The invention provides polyether polyurethane-acrylate and a preparation method thereof. The polyether polyurethane-acrylate comprises the following compositions in portion by weight: 40 to 60 portions of polyether glycol, 10 to 30 portions of polyisocyanates, 10 to 30 portions of hydroxypropyl acrylate or hydroxy-ethyl acrylate, 0.1 to 0.5 portion of triethylamine or dibutyltin dilaurate, 5 to 10 portions of absolute ethanol, 0.1 to 0.8 portion of p-hydroxyanisole or 2.6- di-tert-butyl-4-methylphenol, 5 to 20 portions of tripropylene glycol diacrylate, 5 to 20 portions of TMPTA, and 0.01 to 0.02 portion of nitrobenzene. The invention has excellent mechanical abrasion resistance and toughness, high elongation at break, excellent chemical resistance and high temperature resistance when coating a film, has low temperature performance and good adhesive force. The polyether polyurethane-acrylate has better using effect when assembling epoxy acrylate, and is the polyurethane acrylate with lowest cost.
