Description

technical field [0001] The invention relates to the field of polyurethane materials, in particular to a high-strength heat-resistant and corrosion-resistant polyurethane board and a preparation method thereof. Background technique [0002] Polyurethane board refers to a polyurethane sandwich panel made entirely of PU, or a combination of PU and color steel plate. It is mainly used in industrial and civil building external insulation systems. At present, it has become the most widely used product system of PU. [0003] The strength and heat and corrosion resistance of the polyurethane boards in the prior art cannot meet the needs of actual use, so it is urgent to design a high-strength heat-resistant and corrosion-resistant polyurethane board to meet the needs of actual use. Contents of the invention [0004] In order to solve the technical problems in the background technology, the present invention proposes a high-strength heat-resistant and corrosion-resistant polyuretha...
