Abstract

The invention relates to paper difficult to tear and a preparation method thereof. The paper is prepared from 30-50 parts of polylactic acid fibers, 20-50 parts of anionic starch, 20-50 parts of absolute ethyl alcohol, 20-50 parts of industrial filter paper, 40-70 parts of alkyl ketene dimer, 30-70 parts of solid paraffin and 20-50 parts of vinyl trimethoxy silane. The preparation method comprises the steps of dispersing the polylactic acid fibers and the anionic starch into the absolute ethyl alcohol, compounding the mixture into suspending liquid with the concentration being 5-25%, and conducting ultrasonic vibration for 15-45 minutes in an ultrasonic vibrator; cutting the industrial filter paper into small round pieces, then placing the small round pieces into the filler absolute ethyl alcohol suspending liquid with the concentration being 5-25%, conducting vertical lifting and pulling repeatedly 3-7 times, conducting natural airing, placing the small round pieces into a water-repelling agent ethanol solution with the concentration being 15-45% for standing for 10-30 minutes, then conducting vertical lifting and pulling 3-6 times, making a water-repelling agent be spread on the paper surface for film forming, and conducting natural airing. The paper is simple in preparation process, low in cost, capable of effectively lowering production cost, low in tear index and adhesion resistance and great in air permeability and nontransparency.

Description

technical field [0001] The invention relates to a paper and a preparation method thereof, in particular to a hard-to-tear paper and a preparation method thereof, belonging to the technical field of paper preparation. Background technique [0002] With the continuous enhancement of people's awareness of environmental protection, the development of degradable materials has become a research hotspot in the field of materials in the 21st century. Whether it is to solve the problem of garbage pollution of packaging materials or to solve the problem of increasingly depleted raw materials, especially the raw material resources of the plastic industry based on petroleum resources, research and development of degradable materials are of great significance. [0003] As an essential fiber material for human production and life, its waste has also attracted much attention, especially synthetic chemical fibers, which are difficult to degrade and have become a new source of pollution. At...
