Abstract

PURPOSE:To increase the flame retardancy and to obtain the speaker vibration plate excellent in the rigidity and light weight. CONSTITUTION:The flame retardant agent layer 2 is coated on one or both sides of the cone paper main body 1. As the agent, antimonate compound is mixed to the mixed solution of the acryl system resin liquid and vinylchloridevinyl acetate copolymer and the mixture of inorganic hollow body such as perlite and ''sirasu'' sand to it is used. Since the inorganic hollow body such as ''sirasu'' sand is mixed, heat block effect is obtained and flame retardancy can be increased. Since the flame retardant agent layer can be thicker to obtain desired rigidity and light weight.
