Abstract

The invention provides water-repellency packaging paper based on nanometer plant fibers and a preparing method thereof. The preparing method includes the following specific steps that rice straw is dried in the sun and beaten, the product is soaked in a sodium hydroxide solution, heated, boiled and activated, the pH value is adjusted to be neutral, and pretreated rice straw is obtained; the pretreated rice straw is put into a biological enzyme solution, the mixture is subjected to ultrasonic stirring, inorganic acid is dropwise added, the mixture is subjected to ultrasonic stirring, the product is taken out and filtered with an ultra-filtration membrane, washing is carried out, a hydrogen peroxide solution is dropwise added for bleaching, and a solution containing the nanometer plant fibers is obtained; fillers, cationic starch, bentonite and gummy-substance chemical medicine are added into the solution containing the nanometer plant fibers, the mixture is stirred to be even to form pulp, the pulp is distributed on a forming net, dehydration and drying are carried out, and the water-repellency packaging paper based on the nanometer plant fibers is obtained. According to the water-repellency packaging paper prepared with the method, the rice straw serves as a raw material, nano-cellulose whiskers are formed with the biological chemistry and physical technologies and then prepared into the packaging paper, and the packaging paper has the water-repellency effect accordingly.

Description

technical field [0001] The invention belongs to the technical field of paper packaging materials, and in particular relates to a water-repellent packaging paper based on nano plant fibers and a preparation method thereof. Background technique [0002] The packaging industry is one of the most extensive and most potential industries in my country's current national economy that involves people's lives. Modern four-pillar packaging materials include paper, plastic, metal and glass. Among them, paper packaging has a wide range of sources, cheap price, low cost, good processing performance, good printing performance, opaque, certain mechanical strength, hygiene, safety and light weight. , Degradable and other advantages, compared with other materials has great advantages, is one of the most promising green packaging materials. [0003] In modern society, people are increasingly advocating consumption patterns such as environmentally friendly consumption and reusing resources. G...
