Abstract

The invention relates to metallocene polyethene (PE) rich mineral paper and a making method thereof. The metallocene polyethene (PE) rich mineral paper consists of an upper surface layer, a middle layer and a lower surface layer; the master batch of the upper surface layer comprises the following components in percentage by weight: 40 to 60 percent of titanium dioxide, 35 to 55 percent of metallocene PE, 0.5 to 1 percent of coupling agent, 0.5 to 1 percent of dispersing agent, 0.5 to 1 percent of flame retardant, 0.5 to 1 percent of compatilizer and 0.5 to 1 percent of slipping agent; the master batch of the middle layer comprises the following components: 40 to 60 percent of calcium carbonate powder, 35 to 55 percent of metallocene PE, 0.5 to 1 percent of titanate coupling agent, 0.5 to 1 percent of dispersing agent, 0.5 to 1 percent of flame retardant, 0.5 to 1 percent of compatilizer and 0.5 to 1 percent of slipping agent; and three-layer composited rich mineral paper is made by a three-layer calendering process. The metallocene PE rich mineral paper has the advantages of high tensile strength, moisture resistance, waterproofness, high dimensional stability, tearing and foldingresistance, stable physical dimension, high printing definition and the like.

Description

technical field [0001] The invention relates to a stone paper and a manufacturing method thereof, in particular to a metallocene PE stone paper and a manufacturing method thereof. Background technique [0002] Traditional paper is made of plant fibers such as wood, which does not have the properties of moisture resistance, corrosion resistance and mechanical processing, and cannot meet many special requirements. In the 1950s, plastics and calcium carbonate had appeared. Environmentally friendly synthetic paper produced by blown film method and casting method. Stone paper is the abbreviation of inorganic powder environmental protection stone paper. It is called "synthetic paper" in the paper industry. Calcium carbonate as the main raw material of the mineral resources, with polymer materials and a variety of inorganic substances as auxiliary raw materials, using the principle of polymer interface chemistry and filling modification technology, a reversible recycling process p...
