Flame Retardant Mechanism of Aluminum Hydroxide Flame Retardant

With the increasing application of aluminum hydroxide flame retardants, people's understanding of the properties of flame retardants is becoming more and more in-depth. However, many people still cannot understand how the flame retardant has a flame retardant effect. So the following small series to give you a detailed explanation of the flame retardant mechanism of the product.

1, endothermic effect: in 300~350 DEG C dehydration endothermic, inhibit the temperature of the polymer.

2) The role of coverage. After ATH dehydration, Al2O3 protective film is generated on the surface of combustibles to isolate oxygen and prevent continued combustion.

3, carbonization: aluminum hydroxide flame retardant in the combustion conditions to produce strong dewatering material, is the plastic carbonization and not easy to produce flammable volatiles, so as to prevent the spread of flame.

4, dilution: ATH filling, so that the concentration of flammable polymers decreased. The water vapor released by the dehydration of ATH dilutes the concentration of flammable gases and oxygen, which can prevent combustion.

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.
