Abstract

The invention discloses biodegradable stone paper and a preparation method thereof, and belongs to the technical field of light industrial papermaking. Main ingredients of the stone paper comprise, 50-75 parts of inorganic filler, 20-45 parts of full biodegradable resin, 1-5 parts of coupling agent, 1-5 parts of dispersing agent and 0.5-1.5 parts of brightening agent, wherein the full biodegradable resin is a mixture of carbon-dioxide-based full-degradable plastic and biodegradable polyester. The stone paper prepared by the preparation method is a full-degradable material, and the problem that existing stone paper regards polyethylene as a base body, and resin is not degradable is solved. The stone paper has a series of advantages that the strength is higher, the folding endurance is high, and the whiteness is high.

Description

technical field [0001] The invention relates to biodegradable stone paper and a preparation method thereof, belonging to the technical field of light industry papermaking. Background technique [0002] At present, there are two main types of paper on the market, one is traditional coated paper, and the other is synthetic paper or stone paper. Among them, the main raw material of coated paper is wood pulp. The annual global paper production and consumption have reached 320 million tons. , if 4 trees with an average age of 20 years are cut down per ton of paper as raw materials, then nearly 1.3 billion such large trees will disappear from the earth in one year. At the same time, water pollution, air pollution, etc. It is a headache for countries all over the world. Therefore, at present, all countries are rushing to study synthetic paper, also called stone paper, which is mainly made of paper made by mixing a large amount of inorganic fillers with organic PE, PP and other pla...
