Zusammenfassung: | PROBLEM TO BE SOLVED: To improve lightness, flexibility and nailing properties by using a flame-resistant modified pulp having one or more kinds of compounds selected from a metal oxide, metal hydroxide and metal oxyhydroxide fixed thereto, as a reinforcing material. SOLUTION: The metal oxides have activities for accelerating carbonization of the pulp. The pulp are generally used without drying, and the many metal oxides having crystal water also can be used. When a halogen is used as a counter ion of the metal salt in the production of the metal oxides, the halogen is taken in the metal oxides by partial adsorption or the like, and the effect of the flame resistance is improved because the chain reaction in flaming is inhibited by the halogen. Especially, copper oxides having the formula CuCl2.3Cu(OH)2 are excellent in the effect, hardly dissolved even if washed with water, and stable in the cement. A linter pulp, a hemp pulp or the like can be used as the pulp. |
