LAMINATED SHEET

摘要

PROBLEM TO BE SOLVED: To provide a laminated sheet which is capable of being made fire retardant without necessity of incorporating a halogen such as bromine or chlorine. SOLUTION: The laminated sheet A is formed by laminating both glass woven fabric 1a impregnated with a resin composition and glass nonwoven fabric 1b impregnated with a resin composition. A compound in which (3-40) pts.wt. phosphoric ester and (10-100) pts.wt. aluminum hydroxide are blended with 100 pts.wt. radical polymerization type resin free from halogen, is used as resin composition impregnated into the glass woven fabric 1a. A compound in which (10-400) pts.wt. aluminum hydroxide is blended with 100 pts.wt. radical polymerization type resin free from halogen, is used as resin composition impregnated into the glass nonwoven fabric 1b. Fire retardant properties can be obtained by the flame-retarded effect of phosphoric ester and aluminum hydroxide without necessity of incorporating a halogen such as bromine or chlorine.
