Abstract
PURPOSE:To obtain the acoustic construction material with high rigidity, and greater mechanical strength such as high impulse and which can absorb vibration, by adding organic fiber as the fibrous reinforcing material. CONSTITUTION:In the resin component including thermosetting curing resin, curing agent, inorganic filling agent, and fibrous reinforcing agent, the acoustic construction material is formed by molding and curing the acoustic resin composition including 3wt% or more, preferably 5wt% or more of organic fiber based on synthesis material as the fibrous reinforce agent. For example, the number of parts by weight and the standard percentage of components as indicated below can be used for preparing composition. Unsaturated polyester resin used for general purpose 15pts.wt., 14.4%, dicumylperoxide 0.5pt.wt., 0.5%, zinc stearate one part by weight, 1.0%, calcium carbonate 40pts.wt., 38.3%, barium sulfate 40pts.wt., 38.3% and ''Vinylon '' fiber 8pts.wt., 7.7%.
