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.

Zhongke Flame Retardant Organization Watches 20 Closing Ceremonies

On the morning of October 22, 2022, members of Zhongke Flame Retardant New Materials Co., Ltd. watched the closing ceremony of the 20th Congress under the leadership of General Manager Wang Ligui.

What are the reasons for the failure of flame retardant after adding aluminum hydroxide flame retardant?

Everyone knows that there are two common flame retardants. Today we are going to talk about only one of them. Aluminum hydroxide flame retardant is an environmentally friendly halogen-free flame retardant, which can be widely used in fabrics, wood, plastics, and rubber., Polyurethane and other industries have ideal flame retardant effect. In the process of industrial application, it is found that flame retardant failure occurs when aluminum hydroxide flame retardant is added. The following are the reasons for the failure of aluminum hydroxide flame retardant, how to prevent it, how to deal with the operation, and restore the original function.

As a flame retardant, magnesium hydroxide also need to improve what aspects?

When it comes to flame retardants, everyone is familiar with them. Although we usually have less contact with them, we can know what they are used for from the name. Have to talk about magnesium hydroxide, we all know that its main presentation state is a granular, at present, the market sales of magnesium hydroxide particle size is larger, part of the commodity particle size up to tens of microns, immediately used as a flame retardant, poor dispersion, the physical properties of raw materials greater harm. In industrial production, physical grinding methods are generally used to reduce the particle size to 1 micron. The surface of magnesium hydroxide has high polarity and is easy to agglomerate. As the compatibility of refractory materials and polymer substrates, it not only reduces its flame retardant grade, but also causes more serious harm to the physical properties of raw materials.
