超疏水涂料
近年来，这些涂料因自我清洁，去冰，减少和耐腐蚀性而受到了研究的关注，但仅需进行一些重要的应用。超疏水涂层具有特定的要求，复合结构与低表面能量修饰符之间的合作是制造这些高级材料的基础。欧洲杯足球竞彩
研究人员使用了几种材料，例如二氧化硅和碳纳米管来通过移植涂层欧洲杯足球竞彩，溶胶 - 凝胶方法和热液合成等过程生产粉末和涂料。然后将它们浸入或喷涂以生产涂料。
Other processes include dissolution and mechanical abrasion of the surface of bulk materials such as aluminum, followed by spraying with modified nanoparticles. Whilst these processes can create superhydrophobic coatings with adequate properties, they are complex and costly, hindering their commercial and practical application.

改进涂料
The complexity of current preparation processes has facilitated research into alternative, low-cost, facile strategies. Ceramics have been explored as materials for coatings due to their cost-effectiveness and abundance. Researchers have modified these ceramics with coupling agents and incorporated adhesives to synthesize coatings.
Other studies have explored alternative strategies to manufacture these coatings. Scientists have created several coatings with enhanced transparency, mechanical properties, and chemical stability. However, there are issues with the scarcity of high-quality ceramic materials and cost.
Due to the problems with sourcing abundant and cost-effective raw materials for superhydrophobic coating manufacture, research has turned to the exploitation of waste streams. Using waste materials has the benefits of low cost, sustainability, abundance, renewability, and meets the specific demands of the circular economy concept.
Iron Ore Tailings and Rubber Materials
铁矿石尾矿是采矿和矿产加工行业中的关键废料。它们已经被广泛探索用于在建筑（例如水泥熟料和其他增值产品）等领域的应用中进行的广泛探索。这些尾矿具有与粘土相似的成分，使其成为涂料的理想材料，并增加了增强的稳定性和较宽丰度的奖励。欧洲杯足球竞彩
橡胶材料具有耐欧洲杯足球竞彩磨性和弹性等特性。这些材料已在欧洲杯足球竞彩几种工业应用中进行了广泛研究，其性能比传统的聚氨酯和环氧粘合剂更好。将这些材料纳入涂料中可以提高其弹性和耐用欧洲杯足球竞彩性，从而具有增强的耐磨性功能。
已经对橡胶材料对涂料的影响进行了研究，一项研究使用铝底物上的硅橡胶制成的粘合剂底漆，然后用聚合物和多壁CNT的欧洲杯足球竞彩混合物将其喷洒，以提高热稳定性。掺入了二氧化硅和乙烯橡胶的疏水层，并将涂层加热以赋予其超疏水性能。

研究
作者已经使用改良的铁矿石尾矿和氯普赖橡胶粘合剂制备了一种新型的超疏水涂层。这种低成本的过程产生了异常耐用的复合涂料。
尾矿首先是用球铣削的，并用HDTM和TEOS进行了修饰。这产生了可以在涂料中使用的粉末。粉末中的HDTMS浓度以及反应时间都会影响粉末的润湿性。此外，复合涂料的润湿性在很大程度上取决于粉末浓度。
SiO2纳米颗粒不欧洲杯猜球平台规则地堆放在铁矿石尾矿表面，形成复合结构。复合涂层的表面能非常低，这对于超疏水性应用至关重要。这是由于曾经嫁接到铁矿石尾巴混合物上的长链HDTM的影响。
氯普伦橡胶粘合剂将复合铁矿石尾矿粉末中的颗粒固定。欧洲杯猜球平台此外，它强烈结合底物和涂层。这使得涂层非常耐用，适合高度要求的工业应用。
The coatings produced in the research have several advantageous properties, including superior CA values, low SA, and good self-cleaning properties.

总之
作者表现出了一个低成本，便捷和新颖的过程，用于制备具有增强耐用性和有益特性的超疏水涂层。通过利用关键的废物流来创建这种增值产品，该研究为改善了多个行业的可持续性和循环提供了一条途径。
尽管这项研究的重点是准备涂料的一种废料，但它将帮助将来的研究从其他工业废料生产涂料，这将有助于许多行业达到其净零碳承诺。欧洲杯足球竞彩
