PURPOSE:To obtain a resin plate with a high mechanical strength including stiffness and toughness while maintaining conductivity, kneading property, and form-processing adaptability at a level same as the conventional products, by adding specific amounts of conductive carbon material, inorganic fiber material, and inorganic or organic graft polymer to a polyolefine type resin. CONSTITUTION:To 100 parts of a polyolefine type resin such as a copolymer made by copolymerizing a high density, medium density, or low density polyethylene, a small amount of propylene, butane-1, and hexone-1, 25 to 200 wt parts of carbon black or the like of a good conductivity, 2 to 30 wt parts of alumina fiber or the like, and 0.01 to 3 wt parts of a graft polymer which consists of fluorine type polymer of mean molecular weight 3000 to 40000, an acrylic acid of mean molecular weight 3000 to 40000, or the like, and/or an organic type polymer of their esters and the like are added, then a filler, a plastic material, and the like are mixed adequately, and the mixture is kneaded and formed. By composing in such a way, a heat-plastic resin plate presenting a high conductivity and mechanical strength such as that of construction material can be obtained. |
