Abstract

The invention provides stone paper and a manufacturing method thereof. The stone paper comprises the following components in part by weight: 6 to 12 parts of low-density polyethylene, 6 to 12 parts of linear low-density polyethylene, 3 to 6 parts of hot melt adhesive, 5 to 10 parts of titanium dioxide, 65 to 75 parts of heavy calcium carbonate, 3 to 5 parts of silane coupling agent, 0.5 to 1.5 parts of stearic acid, 0.5 to 1.5 parts of epoxy plasticizer, and 0.2 to 0.6 part of polyethylene wax. In the method, high polymer is used as a base material, the calcium carbonate is subjected to compound modification, other additives are added, the characteristics of the surface chemical principle and modification of the high polymer are used and a special process is adopted; and the stone paper is prepared by mixing the polymer, performing composite modification on the filler, plasticizing the filler and polymer, extruding and casting, and performing calendaring molding. The stone paper and the method have great significance for saving energy, protecting natural resources and improving environment.

Description

Technical field [0001] The invention relates to a non-wood pulp paper. Background technique [0002] my country is one of the largest wallpaper consumers. With the rapid development of China’s economy, especially the continuous improvement of people’s living standards, the per capita living area has become larger and larger, which has also promoted the vigorous development of my country’s real estate market. Buildings, villas, etc. The quality and demand of decoration for wallpaper are constantly improving. Because traditional wallpaper uses wood fiber base paper, it is conceivable that traditional papermaking consumes energy and natural resources, and it also causes serious pollution to the environment. It is necessary to develop new types of paper through new technology to meet the needs of people's rising living standards. . Summary of the invention [0003] The purpose of the present invention is to provide a stone paper and a manufacturing method thereof to overcome the abov...
