Fires have always been natural enemies of people's lives. Fires have burned countless properties and burned countless lives and families. In the event of a fire, the damage can be devastating. With the development of society to this day, the issue of fire prevention is still of concern. Today, Xiaobian summarized a new type of coating suitable for the construction industry-fire-resistant coating. He can effectively avoid or reduce the risk of fire. Even if it is not completely isolated, it can reduce the speed of fire spread. He not only has fire protection function, but also has decoration and other additional properties, which is an indispensable new coating for the development of new society.
"Fireproof paint" is coming! New paint more suitable for building decoration!
I. Thick steel structure fireproof coating
The thick steel structure fireproof coating has good fire resistance and stable performance. Its thickness is between 7 ~ 45mm, the coating is granular, and the thermal conductivity is very low. This fireproof coating uses the heat absorption of its own material to slow down the steel. When the temperature rises, the general fire resistance limit can exceed 2 hours, but the thick particles of the thick fire-resistant coating composition cause the coating to have an uneven appearance and poor decoration, so it is often used in industrial buildings and indoor and outdoor hidden steel structures.
Second, thin steel structure fireproof coating
The thickness of the thin steel structure fireproof coating is between 3 ~ 7mm. The fire protection principle is similar to that of the ultra-thin steel structure fireproof coating. When it is exposed to fire, it will collide and thicken, forming a dense and hard fire insulation layer to protect the steel members. It has good adhesion, durability and water resistance, and also has good decorative properties. Its fire resistance limit is also within 2 hours. At present, in the new fire-resistant coatings market, thin steel structure fire-resistant coatings are gradually being replaced by ultra-thin steel structure fire-resistant coatings, because the performance of the two is basically the same, and in terms of decoration, ultra-thin Fire-resistant coatings for steel structures are slightly better.
Third, ultra-thin steel structure fireproof coating
Ultra-thin steel structure fire-resistant coating has an ultra-thin coating, which can also provide effective fire protection for steel structures. It will slowly expand and foam to form a hard fire insulation layer when exposed to fire. This fire insulation layer is very effective. The fire resistance and heat insulation can alleviate the temperature rise of the steel, thereby effectively protecting the steel components. This steel structure fireproof coating is generally solvent-based, has excellent adhesive strength, can closely adhere to the surface of flammable substrates, and has good weather and water resistance, good leveling and decorative properties. Because it is relatively thin and the thickness is within 3mm, the fire resistance limit of general ultra-thin steel structure fireproof coating is generally within 2 hours, but the ultra-thin steel structure fireproof coating composed of newly formulated materials can exceed or exceed 2 hours.
Fourth, mineral wool building fire insulation coating
Mineral wool construction fire insulation coating not only has better heat insulation and fire prevention effects, but also anti-vibration and sound absorption, so it is very suitable for buildings in earthquake-prone areas. The mineral fiber material in it can also enhance the coating while insulating. Layer strength. It adopts spraying construction method, low cost, fast drying, and can form a coating with a lower density after construction, thereby reducing the load on the building.
Nowadays, there are endless brands of fire-resistant coatings on the market. Everyone must strictly control the selection of new fire-resistant coatings and choose fire-resistant coating products that meet national environmental protection and quality standards.
