Beschreibung
Zusammenfassung:	The invention relates to a preparation method of alcohol soluble normal-temperature curing bi-component polyurethane-acrylate resin. The preparation method comprises the following steps of: preparing a substance A; preparing a substance B; and mixing the substance A and the substance B in the proportion of 3-6:1 to obtain the alcohol soluble normal-temperature curing bi-component polyurethane-acrylate resin, wherein the raw material substance A comprises acrylate, epoxy group monomer, vinylacetate or styrene, more than one type of active functional group monomer, initiating agent and industrial alcohol; and the raw material substance B comprises oligomer polyalcohol, polyisocyanate, chain extending agent, catalyst, polyamine, solvent and industrial alcohol. The alcohol is completely used as the solvent, and the alcohol solubility is favorable; compared with a bi-component polyurethane product, the components contain no toxic and dissociative isocyanate, and the obtained product has strong environmental adapta
