Paper-imitating biodegradable resin and preparation method

Abstract

The invention discloses a paper-imitating biodegradable resin and a preparation method. For improving the degradability and natural recoverability of paper-imitating materials and making the paper-imitating materials have similar lightness, foldability and printing and writing performance as the conventional paper. The paper-imitating biodegradable resin uses mineral fibers, vegetable fibers and starch fibers as main components, and concretely comprises the following components in part by weight: 40 to 70 parts of mineral fibers, 10 to 30 parts of vegetable fibers, 5 to 20 parts of starch fibers, 5 to 15 parts of biopolymer, 3 to 5 parts of modifier, 3 to 5 parts of compatibilizer and 3 to 8 parts of processing assistant. The mineral fibers, vegetable fibers and starch fibers are interweaved through thermoplastic processing, and the preparation process is clear and pollution-free. The paper-imitating biodegradable resin can be processed into various paper-imitating products by hot plasticizing equipment, and the products, when discarded, can be swallowed and decomposed by microbes without polluting the environment.

Description

technical field

[0001] The invention relates to a paper-like biodegradable resin, specifically, the invention provides a biodegradable resin which can be directly used for paper processing and a preparation method. Background technique

[0002] As one of the four great inventions in ancient my country, papermaking is an outstanding creation in the history of human civilization. Paper plays an important role in human's daily life, work and study. Due to the recyclable and degradable characteristics of paper, it is more and more widely used in the field of packaging, and its consumption is increasing. However, while promoting the rapid development of human civilization, traditional papermaking has seriously damaged tree resources, and the production process has caused serious water pollution. my country is an area lacking in forest resources, so my country is the world's largest importer of primary pulp and waste paper. The import of pulp accounts for about 16% of the world'...
