Problems solved by technology

Traditional papermaking technology has at least the following deficiencies: ①. The main raw material for papermaking is wood pulp made from trees. The papermaking industry consumes a lot of valuable forest resources, which is an important factor leading to the imbalance of the earth's ecology
②, the paper industry also consumes a lot of water and energy
③. Most of the production of various papers is produced by wet method. A series of chemical and physical methods are used to produce pulp, which discharges a large amount of acid and alkali waste liquid, pollutes the soil and water, and destroys the environment on which human beings depend. and threats, while the up-to-standard treatment of acid and alkali waste liquid requires a lot of investment, and the treatment is difficult, resulting in increased production costs
④, the production method is complicated, and the equipment investment is large
In the existing materials reported on stone paper or in related patent applications, the inorganic components and inorganic components of stone paper are generalized, and there is no careful selection, so its performance is subject to some restrictions, and its comprehensive performance is lacking. It is not ideal, some are not easy to print, some are lacking in folding resistance and tear resistance, etc., thus affecting the promotion of stone paper

Abstract

The invention provides a stone paper and a processing method thereof, and relates to synthetic papers and a manufacture technology thereof. The stone paper consists of a base paper layer and a coating layer, wherein the coating layer is coated on the base paper layer; the base paper layer consists of 15-30 parts by weight of organic component and 70-85 parts by weight of inorganic component, the organic component is polylactic acid; and the inorganic component comprises light calcium carbonate and lithopone. The processing method of the stone paper comprises the steps of: thermally drying the light calcium carbonate and the lithopone and evenly stirring, mixing with the organic component and evenly stirring, treating by means of banburying and kneading, and pelleting in pelleting equipment; extruding by a calendar to obtain a base paper layer, and treating by corona; and coating a coating material on the surface of the base paper layer. The stone paper is environment-friendly, good in flexibility, good in folding resistance and tearing resistance, and suitable for the common ink, thereby being capable of being used as the paper for the culture, the food, the sanitation, the notebook, the textbook and the printing.

Description

technical field [0001] The present invention relates to synthetic paper and its production technology, especially a kind of paper synthesized with certain inorganic substances derived from stones as the main component, so-called stone paper and its production technology.
