Abstract

The invention discloses a high-hardness heatproof anti-corrosion polyurethane plate. The high-hardness heatproof anti-corrosion polyurethane plate is prepared from the following raw materials of diisocyanate, polyester polyol, hydroxyl-terminated polybutadiene, polyethylene glycol terephthalate, nano silica, organosilicone, nano titania, a modification additive, modified graphene oxide, sulphur, dicyandiamide, zinc borate, a silane coupling agent KH-570, an antioxidant, a releasing agent, a curing agent, a cross-linking agent, a foaming agent and copper sheet. The invention also provides a preparation method of the high-hardness heatproof anti-corrosion polyurethane plate. The prepared high-hardness heatproof anti-corrosion polyurethane plate is high in hardness and good in heat-resisting and anti-corrosion properties.

Description

technical field [0001] The invention relates to the field of polyurethane materials, in particular to a high-hardness heat-resistant and anti-corrosion polyurethane board and a preparation method thereof. Background technique [0002] Polyurethane is a polymer synthetic material with excellent performance. It has both the elasticity of rubber and the hardness of plastic, and also has good mechanical properties, wear resistance and resilience. 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 hardness, heat resistance and anti-corrosion properties of polyurethane boards in the prior art cannot meet the needs of actual use, so it is urgent to design a high-hardness heat-resistant and anti-corrosion polyurethane board to meet the needs of actua...
