Polyurethane flame retardant manufacturer: What are the types of flame retardants
Flame retardant science and technology is a science developed to meet the needs of social safety in production and life, prevent fire and protect people's lives and property. Flame retardant is the application of flame retardant technology in real life, and is a special chemical additive to improve the combustion performance of combustible materials. It is widely used in the flame retardant processing of various decoration materials. When the materials processed by flame retardants are attacked by external fire sources, they can effectively prevent, delay or stop the spread of flame, so as to achieve flame retardant effect. According to the classification standards, flame retardants can be divided into the following four categories.
Flame retardants are industrial additives that make polymers difficult to ignite and slow to burn after ignition. Among many varieties of flame retardants, halogen flame retardants are widely used because of their good flame retardant effect and do not affect the physical and chemical properties of materials. However, the polymers added with halogen flame retardants have a large smoke amount when burning and are easy to release corrosive gases (such as HCl, HBr, etc.) and harmful gases. Easy to cause secondary damage, therefore, today's world flame retardant research is developing towards the direction of non-halogenation, alumina, magnesium hydroxide flame retardant through chemical decomposition of heat absorption and release of water to play a flame retardant role, non-toxic, non-corrosive processing machinery, alumina, magnesium oxide generated after decomposition of chemical stability, so no secondary harm, With the frequent occurrence of fire accidents and the resulting heavy personnel and property losses, it is stipulated that the wires and cables used in the construction of subway and other important buildings must be halogen-free flame retardant wires and cables. However, with the improvement of people's awareness of environmental protection and safety, the halogen-free flame retardant of polymer materials will inevitably be developed in recent years. Aluminum hydroxide (ATH) flame retardant is the most widely used in inorganic flame retardant, the largest amount, magnesium hydroxide flame retardant development is the fastest, the decomposition temperature of magnesium hydroxide is higher than aluminum hydroxide, aluminum hydroxide is about 220, magnesium hydroxide is 350~400, suitable for some polymer processing requirements, also has the role of promoting polymer carbonization, therefore, In recent years, there are many researches on magnesium hydroxide flame retardants and their applications are expanding.
