Embodiment 1

[0039] Step 1. Pretreat banknotes and secret-related waste paper provided by bank departments, banknote printing factories or related departments, optimize the fiber structure and shape of waste banknotes and secret-related waste paper, and obtain pre-modified fibers;

[0040] Step 1.1 Shred waste banknotes and secret-related waste paper. First, coarsely crush paper pieces of about 2cm×2cm, and then continue to use a universal shredder to crush the waste paper pieces into fibers, and control the fiber length of the waste paper paper to about 3-5mm. The fiber aspect ratio is about 10-20, and the fine fiber content is less than 15%;

[0041] Step 1.2 Weigh in turn 100 parts of waste paper fibers obtained in step 1.1, 3 parts of monoalkoxy titanate coupling agent and 20 parts of absolute ethanol, pour the weighed absolute ethanol into a beaker, and then add monoalkoxy titanate coupling agent base titanate coupling agent, stir evenly to obtain a mixed modified liquid, and put the ...

[0047] Step 1. Pretreat banknotes and secret-related waste paper provided by bank departments, banknote printing factories or related departments, optimize the fiber structure and shape of waste banknotes and secret-related waste paper, and obtain pre-modified fibers;

[0048] Step 1.1 Shred waste banknotes and secret-related waste paper. First, coarsely crush paper pieces of about 2cm×2cm, and then continue to use a universal shredder to crush the waste paper pieces into fibers, and control the fiber length of the waste paper paper to about 3-5mm. The fiber aspect ratio is about 10-20, and the fine fiber content is less than 15%;

[0049] Step 1.2 Weigh in turn 100 parts of waste paper fiber obtained in step 1.1, 4 parts of monoalkoxy titanate coupling agent and 20 parts of absolute ethanol, pour the weighed absolute ethanol into a beaker, and then add monoalkoxy titanate coupling agent base titanate coupling agent, stir evenly to obtain a mixed modified liquid, and put the m...

Embodiment 3

[0055] Step 1. Pretreat banknotes and secret-related waste paper provided by bank departments, banknote printing factories or related departments, optimize the fiber structure and shape of waste banknotes and secret-related waste paper, and obtain pre-modified fibers;

[0056] Step 1.1 Shred waste banknotes and secret-related waste paper.

Abstract

A method for preparing a composite material from waste banknote paper, secret-related waste paper and waste plastics, disclosed in the invention, comprises the following steps: preprocessing the wastebanknote paper and secret-related waste paper to obtain pre-modified fibers, uniformly mixing the pre-modified fibers with recovered polyethylene particles, sequentially adding maleic anhydride grafted polyethylene, polyethylene wax, a light stabilizer and an antioxidant 168 to obtain a mixture I, adding the mixture I into a screw extruder, granulating the mixture I, carrying out injection molding on obtained granules by using an injection molding machine, and demolding and cooling the molded granules to obtain the composite material. The method effectively solves the recycling and high-valueutilization problems of the waste banknote paper / secret-related waste paper. The prepared composite material has the advantages of good processability, excellent mechanical performances, low water absorption property, excellent reusability and broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of resource utilization and recycling of waste printing materials, and relates to a method for preparing composite materials by using waste banknote paper, confidential waste paper and waste plastics. Background technique [0002] Waste banknotes are a special kind of waste paper resource. The base paper of banknotes is mainly cotton fiber, which has the characteristics of high fiber purity, long fiber, large aspect ratio, good flexibility and good strength. With the rapid development of my country's economic growth, the circulation of banknotes in the financial field is increasing. Due to many factors such as time, environment, frequency of use, and storage methods, banknotes will inevitably be damaged and replaced. According to the People's Bank of China The Implementation Plan for the Inspection of Recycling Work requires that customers are not allowed to pay less than "70% new" RMB, which further increase...
