Basic introduction and types of flame retardants
Flame retardant is a kind of functional auxiliary agent that can give some polymers that are easy to burn and become difficult to burn. It is mainly designed for flame retardant products of some polymer materials. Its type is very much, according to the method of use can be divided into additive type flame retardant and reactive flame retardant, additive type flame retardant can be in the process of mechanical production, by mechanical mixing method added to the polymer, so that some polymers become flame retardant effect. Today, Xiao Bian will lead you into the world of flame retardants and introduce their relevant knowledge and classification.
Through the front we can know that flame retardants can increase the flame resistance of some polymer materials, mainly used in polymer materials, such as plastic fibers and rubber and so on. However, most of these materials can be burned originally, especially the plastic burns immediately when it encounters fire, so if it can be applied to electrical equipment, construction, transportation, aviation, flight and other aspects, it is urgent to solve the problem of its combustion. Therefore, the use of flame retardants generally requires several conditions. They are heat resistance, improved mechanical strength and will not reduce the physical properties of the polymer material itself. The temperature generated during decomposition cannot be too high. However, in the process of processing, it cannot be decomposed at the processing temperature. At the same time, it must have good durability during use, and it is important to have good quality and low price.
In general, the organic flame retardant itself has a relatively strong affinity, used in plastics, brominated flame retardants in the organic flame retardant system has a certain advantage. Nowadays, flame retardant science and technology, in order to better adapt to the needs of our daily life, prevent the occurrence of fire and protect the life safety of each user, make flame retardant technology fully applied in actual life, and is widely used in the flame retardant processing of various decoration materials. When attacked by external fire sources, it can effectively prevent the spread of flame and achieve the flame retardant effect.
Flame retardants are divided into two categories: physically mixed additive flame retardants and chemically bonded reactive flame retardants. I hope that after reading this article, everyone can have a basic understanding of it and know its function.
