Abstract

The invention relates to the technical field of preparation of novel paper, and specifically to stone paper and a preparation method thereof. The stone paper specifically includes the raw materials of coarse whiting, high density polyethylene, metallocene polyethylene, aluminic ester, polyethylene wax, stearic acid, an antioxidant, and EBS. A process flow is as below: first, evenly stirring coarse whiting and surface treatment agents ethylene wax, stearic acid and EBS, and a coupling agent aluminic ester together in a high-speed mixer through high speed stirring, and modifying the coarse whiting by using the surface treatment agents and coupling agent; then adding the high density polyethylene and metallocene polyethylene, and mixing by stirring; after combination of the above raw materials, conducting extrusion granulation, extrusion casting, three-roll press polish, biaxial tension and corona treatment on the polymer to obtain the stone paper. Biaxial tension process realizes the small difference of tear strength at vertical and horizontal directions of the paper material, and realizes the reduction of original paper density to expand the paper material area, thereby reducing the cost and increasing economic benefit.

Description

technical field [0001] The invention relates to the technical field of preparation of a novel paper material, in particular to a stone paper and a preparation method thereof. technical background [0002] Traditional paper materials are mostly made of plant fibers such as wood as raw materials. With the increasing scarcity of deep forest resources, the raw materials for papermaking are limited to a large extent, and the production cost is also rising steadily. In addition, the traditional papermaking process using plant fibers as raw materials produces three wastes that seriously pollute the environment. [0003] With the rapid development of science and technology, papermaking technology is also changing with each passing day. Calcium carbonate, the most abundant mineral resource in the earth's crust, is used as the main raw material, and polymer materials and various inorganic substances are used as auxiliary materials. Using the principle of polymer interface chemistry ...
