The invention discloses a preparation formula of a polyurethane foamed product based on graphite material. A conductive and thermally conductive material, an insulating and thermally conductive material, is added to the polyurethane foaming raw material to improve the thermal conductivity and parallel electrical conductivity of the polyurethane foamed product. Conductive and thermally conductive materials The number of layers of insulating and thermally conductive materials can adjust the thermal conductivity and electrical conductivity. There is no need to modify the composition of the product itself, which is convenient for production. Using graphite fiber as the main reinforcing fiber, the carbon content of the material is greatly improved, and the mechanical properties are better. , Add titanium dioxide and light-reflecting paint to the polyurethane foam raw material to improve the product's reflectivity to infrared light, thereby isolating the temperature of the inner and outer sides of the polyurethane foam product, and the thermal insulation effect is better. Reflect, avoid photochemical reaction of polyurethane foam products under long-term sunlight, and prolong product service life. |
