At present, some of the active ingredients of the intumescent fire-retardant coatings used in China will slowly precipitate under wet conditions, affecting the fire protection effect. Due to its excellent sealing properties, epoxy resins do not have similar problems. Failure to analyze the activity is the key to maintaining the durability and weatherability of fire retardant coatings. Outdoor fire protection coatings should be based on epoxy paints. The reason is that epoxy paints have better corrosion resistance and lighter weight.
In addition, epoxy fire-retardant coatings have excellent impact strength, adhesion and moisture resistance, and can also be applied in some indoor places such as swimming pools, baths and high-rise buildings. Epoxy fire retardant paint and domestic general fire protection paint, the advantages are expressed in two aspects: First, epoxy resin has a strong sealing performance, can be widely used outdoors. Second, epoxy resin is a thermosetting resin that has the function of resistance to hydrocarbon fires.
A new type of outdoor fire-retardant epoxy fire-retardant paint has replaced thick fire-retardant paints, and the lack of applicable outdoor fire-retardant paints has become a chronic problem in the domestic paint industry. However abroad. There are numerous applications in areas such as hydrocarbon fire hazard structures, marine facilities, petrochemical and petroleum installations, and offshore oil platforms.
Epoxy resins have good adhesion to most materials such as wood, metal, glass, plastics, rubber, leather, ceramics, and fibers. Cured epoxy resin, epoxy resin structure contains aliphatic hydroxyl, ether groups and very active epoxy. With excellent chemical resistance, heat resistance, acid and alkali resistance and good electrical insulation, fireproof paints formulated with it have good adhesion, corrosion resistance and mechanical strength. Epoxy fireproof paints also have excellent sealing properties, flame retardant components do not migrate to the coating surface, so their fire performance is less affected by time and environment. In particular, the epoxy resin fire retardant coating can adhere to the substrate well after the explosion, and is more suitable for offshore oil platforms, oil fields, refineries and petrochemical plants than the aggressive fireproof paint.
Another important reason for choosing epoxy as a film former is that epoxy can be used as a char forming agent for intumescent flame retardant paints. Radical theory believes that the carbon forming agent is the material basis for the formation of a non-flammable foamed carbonized layer, plays a skeleton role on the foamed carbonized layer, and contains some high carbon polyhydroxy compounds. A large number of experiments confirmed that epoxy resin can be used as a carbonization agent, and it can also react with a dehydration catalyst to form a porous structure of a carbonized layer.
