Publish Time: 2025-07-28
At a time when the booming industry and the deep integration of environmental protection concepts are in place, the field of anti-corrosion is undergoing a quiet and profound change. Although traditional anti-corrosion coatings have made great contributions to protecting substrates and extending the service life of facilities, their high pollution and high energy consumption characteristics are gradually drifting away from the increasingly stringent environmental protection requirements. The emergence of water-based bio-based anti-corrosion coatings is like a bright new star. With renewable biological resources as the cornerstone, it has built an indestructible new line of defense for the green anti-corrosion industry with its excellent environmental performance and wide applicability.Natural Gift: Renewable Biological Resources Create an Environmentally Friendly CoreThe biggest highlight of water-based bio-based anti-corrosion coatings is that they use renewable biological resources as the main raw materials. These raw materials come from the generous gifts of nature, such as plant oils, starch, cellulose, etc. They are inexhaustible and inexhaustible, which is in sharp contrast to the non-renewable fossil resources that traditional petroleum-based coatings rely on.Plant oils are one of the key ingredients in bio-based coatings. Vegetable oils represented by soybean oil and linseed oil can be converted into excellent coating base materials after special chemical modification and processing. They not only have good film-forming properties and flexibility, but also can form a uniform and dense protective film on the surface of metal, concrete and other substrates, effectively blocking the intrusion of oxygen, moisture and corrosive media, and are widely available and highly renewable. In the production process, the use of vegetable oils reduces dependence on petroleum resources, reduces environmental pollution and energy consumption caused by petroleum extraction and processing.Natural polymers such as starch and cellulose also add unique environmental advantages to bio-based coatings. Starch has good adhesion and thickening properties, which can improve the adhesion and stability of the coating, making it more firmly attached to the surface of the substrate and not easy to fall off; cellulose can enhance the mechanical properties and water resistance of the coating, and improve the overall quality and service life of the coating. These natural ingredients can be naturally degraded in nature, and will not remain in the environment for a long time like synthetic polymers in traditional coatings, causing environmental problems such as "white pollution".Green Pioneer: Fully Implementing Environmental Protection ConceptsWaterborne bio-based anti-corrosion coatings can be regarded as pioneers in the field of environmental protection, and every link from production to use demonstrates the green concept.In the production process, the use of renewable biological resources as the main raw materials reduces the exploitation and processing of non-renewable resources such as petroleum, reduces energy consumption and greenhouse gas emissions. At the same time, the production process of bio-based raw materials is cleaner than traditional chemical production, produces fewer pollutants, and reduces the pressure on the environment accordingly.During use, waterborne bio-based anti-corrosion coatings use water as a dispersion medium, which greatly reduces the content of volatile organic compounds (VOCs). Traditional solvent-based anti-corrosion coatings release a large amount of VOCs during the drying process. These substances will not only pollute the atmospheric environment, cause environmental problems such as haze and photochemical smog, but also cause harm to human health, such as irritating the respiratory tract, causing headaches, dizziness and other symptoms. During the coating and drying process of waterborne bio-based anti-corrosion coatings, water evaporates into the air, and almost no harmful VOCs are produced, which effectively improves the indoor and outdoor air quality and creates a healthy and safe environment for construction workers and users.In addition, the coating also has good weather resistance and corrosion resistance, which can reduce the frequent updating and maintenance of the coating, further reducing resource consumption and waste generation. After the service life of the coating ends, its bio-based components can be naturally degraded, and will not cause long-term pollution to the soil and water sources, truly realizing environmental protection throughout the entire life cycle from production to disposal.Widely applicable: meeting the anti-corrosion needs of multiple substratesAnother major advantage of water-based bio-based anti-corrosion coatings is their wide applicability, which can meet the anti-corrosion needs of different substrates and provide reliable protection for various industrial facilities and construction projects.For metal substrates, such as steel, aluminum alloys, etc., water-based bio-based anti-corrosion coatings can form a dense chemical protective film, which effectively prevents metals from chemically reacting with oxygen, moisture and corrosive media, thereby slowing down the corrosion rate of metals. In the fields of marine engineering, bridge construction, petrochemicals, etc., metal facilities are exposed to harsh environments for a long time and are vulnerable to corrosion. Using water-based bio-based anti-corrosion coatings for protection can significantly improve the durability and safety of metal facilities, reduce maintenance costs and replacement frequency.Concrete substrates are also one of the applicable objects of water-based bio-based anti-corrosion coatings. Concrete structures will be corroded by moisture, chloride ions, carbon dioxide, etc. during long-term use, leading to problems such as concrete carbonization and steel bar corrosion, affecting the safety and service life of the structure. Waterborne bio-based anti-corrosion coatings can penetrate into the concrete, block the capillary channels, form a waterproof and anti-corrosion barrier, prevent the invasion of harmful substances, and protect the integrity of the concrete structure. In underground engineering, water conservancy projects, sewage treatment plants and other fields, waterborne bio-based anti-corrosion coatings provide a reliable protection solution for concrete structures.In addition to metal and concrete substrates, waterborne bio-based anti-corrosion coatings can also be used for the anti-corrosion treatment of other substrates such as wood and plastic, showing strong versatility and adaptability.Waterborne bio-based anti-corrosion coatings have become the new favorite in the field of anti-corrosion with their renewable biological resources as raw materials, all-round environmental protection performance and wide applicability. In the future development, with the continuous advancement of technology and the increasing requirements for environmental protection, waterborne bio-based anti-corrosion coatings are expected to be widely used in more fields, making greater contributions to promoting the green and sustainable development of industry. Let us work together to build a new line of defense for green anti-corrosion with the power of nature and create a better future.
