What is the role of flame retardant coatings

What does flame retardant paint do

Flame Retardant Coatings - Fire Retardant Coatings 

Flame-retardant coatings are widely used in the construction industry, but their inherent flammability limits their application. In the "Code for Fire Protection of Architectural Design" promulgated by the state, its fire hazard is classified as Class C, which is combustible solid; and according to the "Code for Fire Protection Design of Interior Decoration of Buildings", its combustion performance grade is B2, which is flammable; if not After flame retardant treatment, it cannot be used as a decoration material for building ceilings, and its use in wall decoration is also greatly restricted. In order to control the fire hazard of wood and expand the scope of application, it must be treated with flame retardant coatings.  

In our country 5000 years ago, the method of coating the wood with soil to prevent fire. Later, the wood was wrapped with varnished cloth and then coated with non-flammable substances such as clay and gypsum. In coastal areas, lighthouses have long been constructed of wood treated with seawater. In the 1960s, my country successfully developed non-intumescent fire retardant paints, such as peroxyethylene fire retardant paints. In the 1970s and 1980s, intumescent fireproof coatings, such as amino resin fireproof coatings, were successfully developed, which were used as decorative fireproof protective layers for wood materials. After the 1980s, many universities and research institutes in my country have successively carried out research work on wood flame retardant treatment. At present, there are a large number of coating flame retardant products on the market in my country, most of which use ammonium polyphosphate or amino resin to fix the flame retardant.  

2.10.1 Flame retardant coatings and fire retardant coating methods (1) Wood flame retardants generally require high resistance It can prevent flaming combustion and flameless combustion, control the amount of smoke, and the toxicity and corrosiveness of the smoke emitted by combustion should also be small. High stability to heat and light, not easy to volatilize or leaching, not easy to hydrolyze, strong anti-bleeding, strong weather resistance, durable flame retardant coating performance. It is non-toxic by itself, and its pyrolysis combustion products have less smoke, low toxicity, no irritation and corrosion, and meet the requirements of environmentally friendly green chemical products. It should have good compatibility with other additives. The flame retardant should make the color of the treated wood not change much, not affect its surface decoration, and prevent the internal flame retardant from migrating to the surface during use, making the surface white. frost or cause peeling of paint and coatings. It is easy to use, low in cost, low in dosage and high in efficacy.
