Abstract

The invention provides an environment-friendly waterproof paper and a preparation method thereof. The environment-friendly waterproof paper is prepared from straw, withered tree leaves, bamboo, modified acrylic resin, magnesium oxide particles, pectin, polyester fibers, starch, dilute sulfuric acid, glycerin, lignocellulose, a surface active agent, an additive and a polyvinyl alcohol. The preparedenvironment-friendly waterproof paper has good writing performance and printability, damage of moisture on the paper can be effectively prevented, the hydrophobicity of the paper is ensured, and at the same time, the difficulty and effect of writing and printing of the paper are not influenced; besides, multiple plant components are added into the paper, the paper can be rapidly decomposed by organisms and accordingly is more environmentally friendly and safer, and actual environment protection is achieved.

Description

technical field [0001] The invention belongs to the technical field of paper products, and in particular relates to an environment-friendly waterproof paper and a preparation method thereof. Background technique [0002] The paper packaging industry is one of the fastest-growing fields in the packaging industry, has a large room for development, and has been identified as one of the most promising green packaging materials. The main chemical components of paper are cellulose and hemicellulose, which belong to macromolecular polysaccharides. Its molecular structure is highly hydrophilic, and it is easier to absorb water from the surrounding environment, resulting in a decrease in the strength of the cardboard. Many studies have shown that the strength of paper packaging materials will drop to 10-20% of their original strength after absorbing water and getting wet. Therefore, the waterproof performance of paper packaging materials is very important during transportation and s...
