摘要 |
<p>Wallpaper comprises flame-retardant paper having laminated thereon an expanded sheet obtained by expanding at an expansion ratio of 1.5 or more a composition containing by weight (A) 100 parts of an ethylene- alpha -olefin copolymer having a melt flow rate of from 0.2 to 50 g/10 min, a density of not more than 0.91 g/cm3, and a maximum melting peak temperature of 100 DEG C or higher and a heat of fusion at 100 DEG C or higher of 10 J/g or more measured with a differential scanning calorimeter and (B) 60 parts or more of magnesium hydroxide optionally admixed with up to 80 wt % of aluminum hydroxide. The polymer is obtained by a Ziegler catalysed polymerisation of one or more C3-18 olefin. The components (A) and (B) are mixed, optional additives may be added, the composition expanded with the use of chemical blowing agent and molded into a sheet or simultaneously expanded and molded and laminated to the paper by fusion or adhesive. The wallpaper has high safety, is free from bleeding of a plasticizer, gives off no offensive odor, and satisfies the requirements of second class (semi-noncombustible) or fireproof wall coverings.</p> |
