Problems solved by technology

[0002] In the current technology, the protective and antirust packaging for steel, especially steel coils, is mainly antirust paper or antirust film for the inner layer, and PE plastic board, fiberboard or thin steel sheet for the outer layer, and the cost of PE plastic is relatively high. Moreover, its impact resistance is limited and its weather resistance is poor; fiberboard is not environmentally friendly, and its water and oil resistance and bending performance are relatively poor, and oil leakage, rupture, and breakage are prone to occur during packaging and transportation; Once the steel coil is stored for a long time or shipped by sea, its surface will become discolored, dull and even rusty
In addition, the process of using the inner and outer two-layer packaging structure is relatively complicated, and the packaging efficiency is low
On the other hand, there are many discarded disposable paper-plastic flexible packaging materials and a large amount of waste paper and waste plastics in the production and living links, which cause great pollution to the environment. Paper-plastic separation technology has become a worldwide problem in recent years. Although there are improvements, there are still great defects. How to recycle paper-plastic composites more conveniently and effectively is also an important topic for people to think and study.

Abstract

The invention relates to a paper-plastic composite antirust wrapping plate for steel products and particularly steel coil protection wrapping and a manufacturing method thereof. The paper-plastic composite antirust wrapping plate is formed by performing hot pressing on the following raw materials in percentage by weight: 49 to 79 percent of paper, 20 to 49 percent of plastics, 0.1 to 2 percent of antirust powder and 0 to 3 percent of antistatic agent, wherein part or all of the paper and the plastics are waste paper and waste plastics. The antirust wrapping plate has high protection performance and excellent antirust performance indexes; the adopted raw materials are the waste paper and the waste plastics, so the antirust wrapping plate not only saves resources, but also is favorable for environmental protection, and can also be recycled; the antirust wrapping plate integrates rust protection with wrapping protection, is convenient to use, and can improve the wrapping efficiency of the steel products; and a layer of colored non-transparent plastic film is compounded outside a plate surface by hot pressing to further strengthen the performance of moisture resistance and damp prevention and decorative function of the wrapping plate. The paper-plastic composite antirust wrapping plate has the advantages of simple and convenient manufacturing, abundant raw materials and low cost.

Description

Technical field [0001] The invention relates to a paper-plastic composite anti-rust packaging board used for protective packaging of steel, especially steel coils, and a manufacturing method thereof, and belongs to the technical field of steel packaging materials. Background technique [0002] In the current technology, the protective anti-rust packaging for steel, especially steel coils, is mainly packaged with anti-rust paper or anti-rust film on the inner layer, and the outer layer is packaged with PE plastic board, fiberboard or thin steel plate. The cost of PE plastic is relatively high. And its impact resistance is limited and weather resistance is poor; fiberboard is not environmentally friendly, and its water and oil resistance and bending properties are relatively poor, and it is easy to see oil, cracks, and breaks during packaging and transportation; while packaging with thin steel plates Once the steel coil is stored for a long time or is shipped by sea, its surface wi...
