Reactive polyurethane hot melt adhesive for furniture coating and preparation method thereof

The invention discloses a reactive polyurethane hot melt adhesive for furniture coating and a preparation method of the reactive polyurethane hot melt adhesive. The hot melt adhesive comprises the following raw materials: polyether polyol, polyester polyol, isocyanate, carbonate modified methacrylate HEMAC with hydroxyl groups, an ethylene-vinyl acetate copolymer (EVM) and a catalyst. The reactivepolyurethane hot melt adhesive prepared by the invention meets the requirements of high adhesion and high initial adhesion required by furniture coating lines; meanwhile, the adhesive is good in adhesion to low-surface-energy materials such as PVC and PE, has very good heat resistance, is particularly excellent in water or moisture resistance, and can be applied to the field that the low-surface-energy materials need to be well adhered and may be in a hot, water or moisture environment for a long time. In the field of furniture coating, the reactive polyurethane hot melt adhesive can replacean original EVA hot melt a
