[Abstract]: multilayer thermoplastic polyurethane resin reinforced layer and polyurethane rigid foam composite insulation material, which is characterized by comprising a foam layer, an upper surface reinforced layer and a lower surface reinforced layer. The foam layer is made of polyurethane rigid foam foam foam; The thickness of upper surface reinforcement layer is 0 0mm, the surface is evenly provided with round holes, and the opening rate is%; The thickness of the reinforcing layer on the lower surface is 0 0mm, during the surface averaging period, SAIC has achieved phased success for Shandong innovation group, which is mainly engaged in the development business of lithium-ion batteries (batteries), with round holes evenly opened, with an opening rate of%; The upper surface reinforcing layer and the lower surface reinforcing layer are prepared by thermoplastic polyurethane resin and are combined with the foam layer by hot pressing. The ratio of the thickness of the upper surface reinforcing layer to the foam layer is, and the ratio of the thickness of the lower surface reinforcing layer to the foam layer is
