Embodiment 1

[0028] An environmentally friendly recyclable degradable paper material, the environmentally friendly recyclable degradable paper material is made by mixing gelatinized starch glue with a mass fraction of 20% and 80% paper powder, wherein the gelatinized starch glue includes Tapioca starch, starch modifier, wetting agent, reinforcing agent, polyvinyl alcohol, wherein, the mass fraction of each component is 30% of tapioca starch, 1% of starch modifying agent, 2% of wetting agent, 30% of reinforcing agent, polyvinyl alcohol Vinyl alcohol 37%.

[0029] The specific production steps of the above-mentioned environmentally friendly recyclable degradable paper material preparation method are as follows:

[0030] 1). Preparation of gelatinized starch glue

[0031] Tapioca starch, starch modifier, wetting agent, reinforcing agent, polyvinyl alcohol are according to mass fraction: 30% of tapioca starch, 1% of starch modifying agent, 2% of wetting agent, 7% of reinforcing agent, 60% of ...

Embodiment 2

[0037] An environmentally friendly, recyclable and degradable paper material, made of a mixture of 40% gelatinized starch glue and 60% paper powder; the gelatinized starch glue includes tapioca starch, starch modifier, and wetting agent , reinforcing agent, polyvinyl alcohol, wherein, the mass fraction of each component is 60% of tapioca starch, 2% of starch modifier, 5% of wetting agent, 3% of reinforcing agent, 30% of polyvinyl alcohol.

[0038] The specific production steps of the above-mentioned environmentally friendly recyclable degradable paper material preparation method are as follows:

[0039] 1). Preparation of gelatinized starch glue

[0040] Tapioca starch, starch modifier, wetting agent, reinforcing agent, polyvinyl alcohol are according to mass fraction: tapioca starch 48%, starch modifying agent 2%, wetting agent 5%, reinforcing agent 15%, polyvinyl alcohol 30% Proportionally put into the reactor, stir after adding water, start the reactor and stir until there...

Embodiment 3

[0046] An environmentally friendly, recyclable and degradable paper material, made of a mixture of 50% gelatinized starch glue and 50% paper powder; the gelatinized starch glue includes tapioca starch, starch modifier, and wetting agent , reinforcing agent, polyvinyl alcohol, wherein, the mass fraction of each component is 48% of tapioca starch, 2% of starch modifier, 5% of wetting agent, 15% of reinforcing agent, 30% of polyvinyl alcohol.

[0047] The starch modifier is a degradable polycaprolactone macromolecule, and the starch-based polyurethane (St-PCL) is prepared by introducing the degradable polycaprolactone (PCL) macromolecule into the backbone of the starch molecule and capping it with HDI. To a certain extent, the hydrophobicity and water resistance of starch-based materials are improved. At the same time, St-PCL, as a compatibilizer of the St / PCL blend system, can effectively improve the adhesion between the starch phase and the PCL phase interface and the compatibi...

Abstract

The invention belongs to the technical field of paper materials, and particularly relates to an environment-friendly recyclable degradable paper material and a preparation method thereof. The environment-friendly recyclable degradable paper material is prepared by mixing the following materials in percentage by mass: 20-40% of gelatinized starch glue and 60-80% of paper four, wherein the gelatinized starch glue comprises tapioca starch, a starch modifier, dibutyl phthalate, a reinforcing agent, and polyvinyl alcohol, and the mass fractions of the components are as follows: 30-60% of the tapioca starch, 1-2% of the starch modifier, 2-5% of the dibutyl phthalate, 3-15% of the reinforcing agent, and 30-60% of the polyvinyl alcohol. According to the invention, by virtue of raw material combining and proportioning of the paper material and improvement of a production process, a recyclable, degradable and high-strength paper material is produced, and the requirements on recycling and strength characters are met.

Description

technical field [0001] The invention belongs to the technical field of paper materials, and in particular relates to an environment-friendly recyclable and degradable paper material and a preparation method thereof. Background technique [0002] Today, the ecological environment and environmental pollution problems have attracted great attention from all over the world. The concepts of green environmental protection and green design have emerged as the times require. New requirements have been put forward for the concept of environmental protection and the exploration of sustainable materials. Based on this, a new The concept - "paper material" was also born from this, and has become one of the hotspots in the current material industry research. At present, paper materials have become one of the main applications in paper furniture, paper packaging and other industries due to their characteristics of "Recovery, Reduce, Reuse, Recycle" (Recovery, Reduce, Reuse, Recycle). , t...
