Abstract
PURPOSE: The titled composition, containing a flaky inorganic filler having a specific flake particle diameter and a thermosetting resin, having a high rigidity and a great internal loss equal to that of a wooden plate, and suitable for molding speaker boxes.
CONSTITUTION: A thermosetting resin composition, e.g. an unsaturated polyester resin, is incorporated with preferably 5W80wt% flaky inorganic filler, preferably mica, having a flake particle diameter of 20W300μ as a part or whole of the inorganic filler. Preferably, a powdery filler, e.g. mica or talc, is added thereto in an amount to give a molded cured article having a specific gravity of 1.4W 2.5 and the total amount of the filler of 50W80wt%. A curing agent, fibrous reinforcing material, etc. may be used if necessary.
EFFECT: Molded articles having improved sound insulating properties are obtained because of the flaky filler oriented in layers.
