PURPOSE:To facilitate processing, by constituting the title material by using polyoxypropyleneamine in a bisphenol A type resin being a main agent as a curing agent and adding a modified polyolefin resin and calcium carbonate to said resin. CONSTITUTION:90-120wt.% of an epoxy resin being a main agent, 25-40wt.% of polyoxypolyleneamine as a curing agent, 20-40wt.% of a modified polyolefin resin as a dispersing/holding agent, 0.1-5wt.% of a microballoon as a specific gravity controller and 5-15wt.% of calcium carbonate as a characteristic modifier are mixed under stirring to be injected in a predetermined mold and cured to prepare a phantom. The average atomic number Z' in the material of the phantom is made near to the value of water and the equivalency with water thereof is enhanced. Therefore, the title material easy in processing and preparation and having high durability can be obtained at low cost. |
