Problems solved by technology

[0002] Polyurethane foam products are products made of polyurethane rigid foam. Polyurethane rigid foam is mainly made of isocyanate and polyether. The high-molecular polymer that is mixed with equipment and foamed on-site by high-pressure spraying is often used as thermal insulation and waterproof materials in the construction field due to its low thermal conductivity. In the long-term sunlight, it is easy to cause photochemical reaction inside the polyurethane foam product, thereby reducing the strength of the material and affecting the service life of the material

Abstract

The invention discloses a preparation formula of a polyurethane foaming product based on a graphite material. An electric conduction and heat conduction material and an insulation and heat conductionmaterial are added into a polyurethane foaming raw material; the thermal conductivity and the parallel electrical conductivity of a polyurethane foaming product are improved; in the production process, the adjustment of heat conduction and electric conduction performances is realized by changing the number of layers of the electric conduction and heat conduction material and the insulation and heat conduction material; the components of the product are not changed, the production becomes convenient; graphite fibers are used as main reinforcing fibers; the carbon content of the material is greatly improved, the mechanical property is better, titanium dioxide and a light reflection coating are added into the polyurethane foaming raw material, and the reflectivity of the product to infrared rays is improved, so that the temperatures of the inner side and the outer side of the polyurethane foaming product are isolated, the heat preservation and insulation effect is better, the added lightreflection pigment can reflect ultraviolet rays, the polyurethane foaming product is prevented from carrying out a photochemical reaction in a long-term sun exposure state, and the service life of theproduct is prolonged.
