The invention provides a composite high-strength plastic cover plate material for a cable duct and a preparation method thereof, wherein the cover plate sequentially comprises a cover plate inner layer, a foamed fiber layer and a cover plate outer layer, and the cover plate is prepared by sequentially laminating and hot-pressing the cover plate inner layer, the foamed fiber layer and the cover plate outer layer; the cover plate inner layer is arranged on the inner layer of the cover plate, so that the flame retardant property and the heat insulation property of the cover plate are improved; the outer ageing resistance that can improve the apron of apron, temperature toleration to and wear resistance, the foaming fiber layer is located the apron inlayer, between the apron outer layer, and graphite alkene/glass composite fiber can form the fibre network in the fibrous layer, strengthens the mechanical strength on fibrous layer, improves resistant bending property, and foaming material and elastic material can improve the deformability on fibrous layer simultaneously to alleviate inlayer and skin because the stress difference that the radius of buckling difference brought improves the cohesion between the panel. |
