PURPOSE:To prevent whitening caused by bending or rubbing by making a composition out of a heat treated material in which an oxime or nitroso compound or an organic peroxide are added to a fire-resistant composition composed of an olefine system resin and a hydrate of a metallic oxide. CONSTITUTION:For the formation of a fire-resistant composition, 50 to 250 pts.wt. of a hydrate of a metallic oxide is added to 100 pts.wt. of an olefine system resin. In addition, a whitening inhibitor is added to the fire-resistant composition. As the whitening inhibitor, at least one kind among a group of an oxime, nitron compound and an organic peroxide is used. When an oxime or nitroso compound is used, the appropriate proportional weight is 0.1 to 20 pts.wt. to 100 weight part of olefine system resin. When an organic peroxide is used, the appropriate proportion is 0.1 to 3 pts.wt. to 100 weight part of olefine system resin. By means of the heat treatment for the mixture of the added component, whitening proof ability is imparted to the whitening proof fire-resistant composition, and the material characteristic can be improved. |
