主 题：Basalt Organic coatings Mechanical properties Corrosion resistance
摘 要：Natural basalt can be processed into rod-like basalt fibers(BFs) and flake-like basalt scales(BSs) through high-temperature melting, forming and other processes. BFs and BSs have great application prospects in the field of organic coatings. BFs possess a regular rod-like structure and excellent mechanical properties, which are mainly used to enhance the mechanical properties of organic coatings. BSs possess a relatively irregular flake-like structure, which can form “maze effects and layered structures to enhance corrosion resistance of organic coatings. However, basalt materials have poor compatibility, adhesion, and dispersion in organic resins due to their chemical inertness, resulting in a weak basalt-resin interface. Basalt-resin interface is an important parameter that determines the service performance of basalt composite coatings. Therefore, it is necessary to improve basalt-resin interface through corresponding strategies, such as chemical etching, chemical grafting and plasma treatment. Firstly, the surface modification strategies for improving basalt-matrix interface were summarized in this paper. Secondly, we discussed the effects of BFs and BSs on corrosion resistance of organic coatings and corrosion protection mechanism of composite coatings. Finally, we reviewed the research progress of modified basalt materials reinforced organic coatings.
