Talk about the development and application of fire-resistant coatings in 2019

The rapid development of economy has improved the appearance of the city, but with it, the fire danger is getting higher and higher. With the wide application of polymer materials in various places, the potential danger of fire is also increasing, many high-rise building building components in the high temperature loss of load capacity caused the collapse of buildings, causing huge losses to people's lives and property. Especially in recent years, the fire prevention of buildings has attracted worldwide attention

. Fire-resistant paint applied to the surface of the object, in the event of fire coating itself is difficult to burn or non-combustible, the substrate has a better protective effect, for fire extinguishing and evacuation of personnel to win time. Therefore, its research and application has attracted great attention from all over the world.
history of fire-resistant coatings, we have experienced a cycle from inorganic to organic to inorganic. At the coming of the 21st century, China's fire protection coatings will enter a higher stage of development. As the coatings industry moves toward energy-efficient, low-polluting, high-performance, and specialized directions, fire-resistant coatings are moving in the direction of "five E", i.e., improving the quality of coating films (Excellence), easy to apply, saving resources , saving energy, and eco-balancing (Ecology).
1, environmentally friendly development direction
At present, the domestic common use of solvent-based and thick fire-resistant paint fire resistance limit is poor, does not meet environmental protection requirements, in its use will also be due to people's increasing attention to environmental pollution and personal health has been more and more stringent restrictions. This requires the development of non-polluting coatings, such as water-based fire-resistant coatings and inororable fire-resistant coatings.
water-based coatings, because of non-toxic safety, save resources and protect the environment, has become the main direction of the development of architectural coatings. Water-based expandable fire protection coatings will become the main development direction of fire protection coatings, and should focus on further improving the water resistance, fire resistance and decoration of the coating.
2, low-cost development direction
because of the expansion of fire-resistant coating production process is more complex, high technical content, so the cost is relatively high. However, with the in-depth study of fire-resistant coatings, under the premise of ensuring the performance of fire-resistant coatings, the cost reduction is within reach.
3, high-performance development direction
break through the traditional expansion system and mode, can use expansion and non-expansion type fire-resistant coating combination, the formula contains both expansion-type components, but also contains more fire-resistant filler components, but also add high melting point inorge fiber, so that the coating under the action of high-temperature flame to form a high-strength ash layer with low expansion rate, to ensure that the expansion coating long-term fire insulation without falling off.
4, multi-functional development direction
With the improvement of human culture and living standards, fire protection coatings in addition to the requirements of fire protection and exquisite decorative, but also need to have insulation, insulation, silence and other special functions. Research and development of functional composite steel structure fire-resistant coatings and resins and additives that can give special functions to coatings is a major issue today.
In addition, when we research and develop fire-resistant coatings, we should not only pay attention to the research of fire-resistant performance, chemical and chemical performance and use performance, but also improve the technical level of the production process, we must ensure product quality, to achieve safety and effectiveness. In-depth study of the construction application performance of various types of fire-resistant coatings, including the adhesive properties of fire-resistant coatings on substrates, matching and coating service life, should be given sufficient attention, scientific research and evaluation, for users to put forward the technical basis for the useful life.
