Recent advancements in corrosion protection technology may have significant implications for the construction sector, particularly through the innovative use of SiO2 aerogel loaded with benzotriazole (BTA) corrosion inhibitor. A study led by Hao Guoqiang and his team from the School of Chemistry and Chemical Engineering at Shanghai University of Engineering and Technology, in collaboration with T&H Novel Materials Co., Ltd., has unveiled promising results that could alter the landscape of protective coatings in construction.
The research, published in ‘Cailiao Baohu’ (Materials Protection), investigates how SiO2 aerogel can enhance the effectiveness of K2SiO3 coatings by integrating a corrosion inhibitor that releases slowly over time. This innovative approach addresses one of the industry’s most pressing challenges: protecting structures from the damaging effects of corrosion, particularly in harsh environments.
Hao Guoqiang remarked on the significance of their findings, stating, “Our study demonstrates that SiO2 aerogel not only effectively carries the BTA corrosion inhibitor but also ensures its gradual release, providing long-term protection for K2SiO3 coatings.” This slow-release mechanism is particularly beneficial in environments where traditional coatings may fail, as it offers sustained protection against moisture and corrosive agents.
The research highlights that the effective loading of BTA in the SiO2 aerogel reached a mass fraction of 17.6%, showcasing its potential to significantly enhance the corrosion resistance of K2SiO3 coatings. The team conducted extensive testing, including electrochemical impedance spectroscopy (EIS) and neutral salt spray resistance tests, which revealed that the modified coatings exhibited impressive durability, with no visible rust after 30 days of exposure to salt spray.
This breakthrough has significant commercial implications. As construction projects increasingly prioritize longevity and sustainability, the ability to extend the lifespan of protective coatings can lead to reduced maintenance costs and improved safety for structures. The construction industry, often burdened by the financial impacts of corrosion-related damage, stands to benefit greatly from such innovations.
Moreover, the findings suggest that incorporating advanced materials like SiO2 aerogel into existing systems could pave the way for more resilient construction practices. As the industry continues to seek solutions that align with environmental standards and economic efficiency, this research offers a glimpse into the future of corrosion protection.
