摘要

全球70%的货物是用瓦楞纸板包装运输的。这些包装应确保足够的耐水性，特别是那些专门用于运输危险材料的包装。这项工作的目的是通过硅烷改性淀粉的表面处理，为回收的亲水包装材料（多次回收）的表面疏水开发一种解决方案，以满足“国际危险货物公路运输协定”中概述的耐水性要求。用甲基三甲氧基硅烷改性小麦淀粉对再生纤维基纸板进行表面处理，分析了改性淀粉中硅烷的分布，并对表面处理纸板的疏水性和强度性能进行了分析。该分析可以确定硅在改性淀粉中的均匀分布，表面处理对所得产品的强度性能没有显著影响，最重要的是，通过分析接触角(>；120°)和Cobb1800sec (<；30 g / m2)。

Sustainable hydrophobization of paper and packaging for road transport of dangerous goods – surface treatment with silane-modified starch

>70 % of goods worldwide are transported in packaging made of corrugated cardboard. These packaging should ensure adequate resistance to water, especially those dedicated to transporting hazardous materials. The aim of the work was to develop a solution for the surface hydrophobization of recycled hydrophilic packaging materials (recycled multiple times) by surface treatment with silane-modified starch in order to meet the water resistance requirements outlined in “The Agreement concerning the International Carriage of Dangerous Goods by Road”. Recycled fiber-based cardboard was surface-treated with wheat starch modified with methyltrimethoxysilane, and the distribution of silane in the modified starch and the hydrophobic and strength properties of surface-treated cardboard were analyzed. The analysis made it possible to determine the uniform distribution of silicon in the modified starch, the lack of a significant impact of surface treatment on the strength properties of the obtained products, and above all, the high and durable hydrophobic effect for the treated recycled fiber-based cardboard determined by the analysis of the contact angle (> 120°) and Cobb_1800sec (< 30 g/m²).

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
