Why can magnesium hydroxide be used as a common flame retardant?

With the continuous improvement of living standards, people's requirements for the quality of life are getting higher and higher, and some polymers have entered our daily lives. However, these polymer materials have a problem during use, that is, flammability, which can easily lead to fire accidents. Therefore, we need to add flame retardants to these materials to prevent fires. Common flame retardants include aluminum oxide, aluminum hydroxide, zinc oxide, magnesium hydroxide, and the like. Among these commonly used flame retardants, magnesium hydroxide is widely used.

Why?Magnesium hydroxideCan be added to various polymer materials as a common flame retardant? This is because it decomposes during heating to release bound water to absorb a large amount of latent heat and reduce the surface temperature of the synthetic material filled in the flame. It can also suppress smoke. When a fire produces a large amount of smoke and heat conduction, people cannot escape from the scene. Magnesium hydroxide can solve this problem well and reduce the risk of suffocation by smoke. In addition to flame retardant, smoke suppression and other characteristics, magnesium hydroxide is also widely favored by people because of its environmental protection and non-toxicity. Used in rubber, chemical, building materials, plastics, electronics, paint, paint and other industries.

1. Magnesium hydroxide flame retardant is cost-effective and can be added to polymers to achieve high loading.

2. The thermal decomposition temperature of magnesium hydroxide reaches 340 ℃, which is beneficial to increase the processing temperature of plastics, accelerate the extrusion speed, improve the plasticizing effect, shorten the molding time, and have high surface gloss, no surface defects, and ensure the super peel strength.

3. Magnesium oxide produced by the combustion and dehydration of magnesium hydroxide is a high-strength, high-heat-resistant material, which can be used as a protective wall to isolate fire sources and toxic and harmful gases. Magnesium hydroxide and acid have strong neutralization ability, which can quickly neutralize the acid gas generated during the combustion of plastics.

4. The physical form of magnesium hydroxide is granular, which is conducive to uniform distribution, good compatibility with the substrate, and has little effect on the mechanical properties of the product.

About the above content today to introduce so much, presumably we have a clear understanding, through the above described, we can see that magnesium hydroxide is a very ideal flame retardant, used in various industries.

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.
