How to improve the application effect of magnesium hydroxide flame retardant?

Everyone knows that flame retardants are still used in our lives and play an extremely important role. Among them is magnesium hydroxide, which is widely used as a flame retardant in plastic and rubber products. Its mechanism of action is: release water through thermal decomposition, absorb a large amount of latent heat, reduce the surface temperature of synthetic materials filled in the flame, inhibit polymer decomposition, and cool The surrounding combustible gas: magnesium oxide decomposition is a good refractory material, which helps to improve the flame retardant performance of synthetic materials, and water vapor can also be used as a smoke suppressant.

ImproveMagnesium hydroxideFlame retardant, smoke suppression, filling and other functions, it is important to make it have good compatibility with polymer polymers, and can be evenly dispersed in plastic and rubber systems. At present, the method used is to use a specific powder modifier to modify the surface of magnesium hydroxide, which can effectively reduce the surface energy of the powder, improve the shortcomings of strong polarity and easy agglomeration of the powder, and improve the compatibility of magnesium hydroxide and polymer.

I think everyone should understand the above clearly. Of course, in the current form, it appliesMagnesium hydroxideSurface modification additives mainly include surfactants (stearic acid, sodium stearate, etc.), coupling agents, etc. Various types of additives using different modification methods, including ultra-fine method, surface chemical coating and microcapsule modification methods, need to be explored according to the actual application needs to find a better production process.

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.
