Abstract

PURPOSE:To exhibit the excellent sound absorption properties by pressing a compound in the specified conditions which consists of slag having specified size, thermosetting powdery resin and kerosine and has the specified rate thereof, heating and molding this pressed compound. CONSTITUTION:This sound absorbing material is obtained by pressing a mixture of by weight 80-98% slag particle 1 crushed to 1-5mm<3> size, 1.5-15% thermosetting powdery resin 2 and 0.2-2.0% kerosine at 15-50kg/cm<2> pressurizing force in 5-15sec pressurizing time and heating this pressed mixture at 150-350 deg.C and molding it. Slag itself is porous and also many spaces 3 are present between the particles 1 and therefore this sound absorbing material exhibits the excellent sound absorption properties. Further mechanical strength is enhanced by molding this sound absorbing material into a plate and interposing a wire gauze to the intermediate part. When size of the particle 1 is less than 1mm<3>, porosity is impaired. The appearance is impaired in the size not less than 5mm<3>. The quantities of resin 2 and kerosine are preferably regulated to the above- mentioned range from the viewpoint of function and cost.
