Non-halogen fire retardant composite (Mgoh2 - Epoxy)

In summary, the conversation revolves around research for a thesis on non halogen fire retardant composite. The main result is confusing as the addition of Magnesium Hydroxide to resin epoxy does not seem to have any impact on fire retardancy. Suggestions are given to try aluminum trihydrate instead, which has shown promising results. Another partner's research also supports the combination of Magnesium Hydroxide and aluminum trihydrate for improved fire retardancy. However, it is noted that a certain percentage of Magnesium Hydroxide is required for this effect to be seen.

Hello, I'm currently doing research for my thesis about non halogen fire retardant composite. One of the main result is deviate and confusing because: There is no fire retardancy's effect of Magnesium Hydroxide addition to resin epoxy. Why?Any suggestions?

Thanks

Are you doing UL burns? Horizontal or vertical? You're saying zero flame retardancy vs a control?

Yes it's UL 94 Vertical. There is no fire retardancy's effect or zero flame retardancy. The weight of Magnesium Hydroxide is varied based on total weight of composite

Have you tried aluminum trihydrate?

Yess, the fire retardancy's effect of aluminum trihydrate addition is pretty good.. My main research is actually combination between both aluminium trihydrate and Magnesium Hydroxide. But there is no effect of Mgoh2 addition..

My partner has done the similar research using unsaturated polyester resin, and the result shows that the combination of Mgoh2 and AlOH3 could increase the fire retardancy. But there is a role of Mgoh2 to improve fire retardancy, because around 10-30%wt of Mgoh2 was used.
 

What is a non-halogen fire retardant composite?

A non-halogen fire retardant composite is a material that is used to reduce the flammability of other materials. It is made up of a combination of magnesium hydroxide (MgOH2) and epoxy, which work together to inhibit the spread of fire.

How does MgOH2 - Epoxy work as a fire retardant?

MgOH2 - Epoxy works as a fire retardant by releasing water vapor when exposed to high temperatures. This vapor dilutes the oxygen in the air, making it harder for the fire to continue burning. It also absorbs heat, which further helps to slow down the spread of fire.

What are the benefits of using MgOH2 - Epoxy as a fire retardant?

There are several benefits to using MgOH2 - Epoxy as a fire retardant. It is a non-halogen material, meaning it does not contain harmful chemicals that can be released into the environment. It is also non-toxic and does not produce any toxic gases when exposed to fire. Additionally, it has a high decomposition temperature, making it effective in a wider range of temperatures.

What types of materials can be treated with MgOH2 - Epoxy as a fire retardant?

MgOH2 - Epoxy can be used to treat a variety of materials, including plastics, rubber, textiles, and wood. It is commonly used in building materials, such as insulation, cables, and coatings, to improve their fire resistance.

Are there any limitations to using MgOH2 - Epoxy as a fire retardant?

While MgOH2 - Epoxy is an effective fire retardant, it does have some limitations. It is not suitable for use in high-temperature environments, as it decomposes at temperatures above 340°C. It also has a lower flame-retardant efficiency compared to some other chemicals, meaning it may need to be used in higher concentrations for the same level of fire protection.
