I. Background of water-based architectural steel structure coatings


In recent years, following the development of national environmental protection policy to promote the development of environmentally friendly water-based coatings has become the development of many coatings industry transformation must be the way, water-based coatings also ushered in the rapid development. China is promoting the development to the building industrialization, modernization, take the road of industrialization development, and put forward a new type of building industrialization can realize the building energy saving and environmental protection, so that the life cycle value maximization of the sustainable development of new building methods.

       Building steel structure is a representative green building, the material is recyclable and recyclable, with good seismic performance, sustainable development, the concept of circular economy embodied in the steel structure building building design, construction, demolition and other all processes, are green and environmentally friendly. Therefore, steel structure is more suitable for the current industrialized production and assembly building development and demand, and also more in line with the development direction of national environmental protection.




Introduction of water-based architectural steel structure coating


Steel structure is an important material used in construction, in order to achieve a long service life and aesthetic degree, usually choose some paint spraying on it, there are a lot of steel structure manufacturers in the appearance of the spraying time to choose the corresponding cheap traditional paint, it is obvious that this will cause environmental pollution and health effects. The country for environmental protection is quite strict control, industry, if the steel structure coating application because of environmental protection index is not qualified, it is really not worth the loss.


Water-based architectural steel structure coating is a new type of coating that can replace the traditional coating, which can be applied in the industry. Water-based architectural steel coating is the use of water as a diluent, no need to add other chemicals, so fundamentally eliminate the organic solvents, which will not cause pollution to the environment, will not cause health effects on people's bodies.

Third, the application of water-based architectural steel structure coatings


China in the construction steel structure materials accounted for 46% of the application in the plant, followed by 30% of the commercial building materials, transportation hubs accounted for 10% of the amount of building materials, venues and public building materials accounted for 10% of the amount of residential steel structure materials for buildings only accounted for 4% of the amount of materials.


As the country accelerates in the construction of new infrastructure projects, with the diversified development of rail locomotives and railroad vehicles, the types of rail transportation are more diversified, and intercity rail transportation has also become one of the important focuses for the development of new infrastructure projects in China. The use of architectural steel structures in commercial buildings and transportation hubs will therefore grow further.


The Ministry of Housing and Construction pointed out in "Going All Out to Grasp the Key Work in 2020" that it will vigorously develop building energy-saving and green buildings, promote the pilot construction of steel structure assembled residential buildings, and promote the transformation of construction methods. This includes: actively carrying out pilot construction of steel-structured assembled farm houses and design activities in the countryside, and improving the quality of design and construction of farm houses. This will further expand the market for construction steel structures and increase the application of steel structures in the residential market.


With the construction of landmark buildings (such as the China Pavilion at the Shanghai World Expo, Shanghai Center Tower, Shanghai World Financial Center, Shanghai Disneyland, etc.) in recent years have used waterborne coatings, driving the trend of adopting waterborne coatings in architectural design institutes. In addition, provinces have also put forward clear requirements for VOC emissions from steel structure coating process and made implementation programs to vigorously promote the application of water-based architectural steel structure coatings.

Advantages of water-based architectural steel structure coatings


The most critical part of waterborne architectural steel structure coating is waterborne primer, which accounts for 89% in the whole waterborne architectural steel structure coating. Waterborne primer is mainly based on waterborne inorganic zinc-rich primer, and there are many domestic coating enterprises producing waterborne inorganic zinc-rich primer, with more mature manufacturing and construction technology, and the market share reaches 60%~70%. Followed by water-based acrylic coatings and water-based alkyd coatings. Water-based epoxy primer and water-based polyurethane topcoat supporting system is also in the application.


For the national new infrastructure projects and the renovation of old neighborhoods, green and environmentally friendly water-based architectural steel structure coatings will also be further developed in the market, and water-based architectural steel structure coatings are likely to maintain a high growth rate of more than 20%.
