Abstract
The invention relates to a non-inflammable fiber product that can be used as flame-resistant material or insulating material or both. The invention seeks to provide a material made of used cellulose or cellulose-containing refuse, which had not been sensibly used hitherto. The new fiber product consists of 30 to 97 wt. % cellulose-containing fiber or a cellulose-containing fiber mixture; 0.01 to 1 wt. % nonionic surface active agent; 1 to 5 wt. % aluminum oxide finely distributed on and in the fibers, and 0 to 68 wt. % filling material, as well as optionally one or more additional biocides. Said product can be processed in bulk or as pressed plate.
Claims14
A nonflammable fiber product, comprising:
- 30 to 97 wt % of a cellulose-based fiber or a cellulose-based fiber mixture;
- 0.01 to 1 wt % of a nonionic surfactant and
- 1 to 5 wt % aluminum oxide distributed finely in and on the fiber.
A process for producing a nonflammable fiber product wherein an aqueous 1 to 15 wt % solution of aluminum hydroxychloride containing 0.05 to 1 wt % of a nonionic surfactant is applied to a cellulose-based fiber or a cellulose-based fiber mixture by a mixing, impregnating, dipping or spraying method and then drying, with the fiber product also contains 0 to 68 wt % of a filler or a filler mixture, based on the total weight, in addition to 30 to 97 wt % fibers.
