    • A nonburning paper which is suitable for printing, writing, etc., is disclosed. The basic ingredients of the nonburning paper are: fiber glass, alkali metal silicates and halogenated elastomers. The method of producing this nonburning paper, which will extinguish itself in pure oxygen, is as follows: impregnating a sheet of fiber glass with a solution of an alkali metal silicate; evaporating the volatile solvent from the impregnated material; impregnating the treated fiber glass with a solution of a halogenated elastomer; and evaporating the volatile solvent from the impregnated material. The resultant sheet of paper is nonburning and, in those cases where its preparation is so tailored, it can be used as writing paper or can be used in conventional printing press, such as, offset lithographic printing press.
    • 公开了适用于印刷,书写等的非燃烧纸。 非燃烧纸的基本成分是:玻璃纤维,碱金属硅酸盐和卤化弹性体。 生产这种在纯氧中自身消失的非燃烧纸的方法如下:用碱金属硅酸盐溶液浸渍一片玻璃纤维; 从浸渍的材料蒸发挥发性溶剂; 用卤化弹性体的溶液浸渍经处理的玻璃纤维; 并从浸渍的材料蒸发挥发性溶剂。 所得到的纸张是不燃烧的,并且在其制备如此定制的情况下,其可以用作书写纸,或者可以用于常规的印刷机中,例如胶版印刷机。
