Abstract

The invention discloses a method for manufacturing light-weight black stone paper by utilizing amorphous graphite ore surrounding rock. Dried amorphous graphite ore surrounding rock powder is made into micropowder in 1500-2000 meshes by carrying out airstream pulverization; the micropowder, high-molecular polymer and auxiliary materials are mixed to be uniform, and aggregates used for papermaking are made under the high temperature condition by adopting a screw extruder; and the aggregates used for papermaking are calendered, biaxially stretched and foamed to obtain the light-weight black stone paper. According to the method, resources which are rich and are easy to mine, sort and process are adopted, the excellent light-weight black stone paper is made by adopting a reasonable formula and process, and the light-weight black stone paper can be applied to a shading window, plant illumination regulation and flower formation, so that the method disclosed by the invention has great significance in energy conservation, environmental protection and improvement of the environment.

Description

technical field [0001] The invention relates to the technical field of new decorative materials, in particular to a method for producing light-weight black stone paper from earthy graphite surrounding rocks. Background technique [0002] Paper and paper products are necessities for people's life and office, and the consumption level of paper marks the level of national economic development and people's living standards. Ordinary paper is made of plant fibers. A large amount of chemical raw materials such as acid, alkali, and bleaching powder are used in the manufacturing process, which often brings serious pollution to the environment. A large number of trees are cut down for paper production, and the damage to the environment also affects human life and ecology. balance. [0003] "Lightweight black stone paper" is made of inorganic mineral raw materials, polymers and auxiliary materials. It does not produce pollution during the production process, has low cost, does not de...
