Green building has become an important development trend in the global construction industry. In this trend, the exploration of green defoamers in the construction industry is particularly important. Green buildings emphasize environmental protection, energy conservation, and sustainability, and correspondingly increase the requirements for defoamers. Defoamers should be non-toxic, harmless, easy to degrade, and not cause environmental pollution. They should have excellent defoaming performance, and can quickly and effectively eliminate foam in building materials. It should also have good stability and be able to maintain stable performance under various construction conditions.

In response to the requirements of green buildings, the research and development direction of green defoamers mainly focuses on the following aspects:

Biobased raw materials: Utilizing renewable resources to prepare defoamers, reducing dependence on traditional petrochemical raw materials.

Green synthesis process: adopting environmentally friendly and low-energy synthesis processes to reduce the carbon footprint in the production process.

Multifunctionality: Develop green defoamers with multiple functions such as defoaming, waterproofing, and reinforcement to improve the comprehensive performance of building materials.

In recent years, there have been many successful practical cases of green defoamers both domestically and internationally. The bio based defoamer developed by a certain company is made from vegetable oil through a special process and has excellent defoaming performance and environmental friendliness. The water-based defoamer developed by a certain research institution uses water as a solvent, is non-toxic and harmless, easy to handle, and has been widely used in the production of green building materials.

Under the trend of green building, the exploration and practice of green defoamers are of great significance. Through technological innovation and green practices, the green development of the construction industry can be promoted, contributing to the construction of a beautiful home.
