In order to prevent some easily flammable objects from igniting, some flame retardants are usually added to act as a flame retardant. Magnesium hydroxide is such an ideal flame retardant additive. This is inseparable from its own characteristics.
1. Magnesium oxide produced after burning and dehydrating magnesium hydroxide has high strength and good heat resistance. It can play a protective role and promptly block fire sources and harmful gases. The reaction between magnesium hydroxide and acids will produce non-polluting substances.
2. The particle size distribution is uniform, and it is well compatible with the substrate and has almost no impact on their mechanical properties.
3. Strong decomposition ability, high flame retardant efficiency, good smoke suppression ability; low hardness, low friction, will not damage equipment.
4. The thermal decomposition temperature of magnesium hydroxide is very high, which will also increase the plastic processing temperature and improve the plasticizing efficiency.
5. The cost is low, and there is no need to spend a lot of money on magnesium hydroxide flame retardant in actual production.
Therefore, these characteristics of magnesium hydroxide make it an ideal flame retardant.
How to cross-integrate cost-effective ordinary flame retardants with slightly higher-priced environmentally friendly flame retardants is what many industries need today It is an important topic for research and is also the development direction of flame retardant products in the future. While protecting people and property from the threat of fire, we must also reduce the potential harm caused by flame retardants to our human bodies and the environment. In fact, any chemical substance has advantages and disadvantages for us. How to seek advantages and avoid disadvantages is what we have to do. The key lies in scientific management and correct use.
At present, flame retardants are mainly divided into four types: organic, inorganic, halogen and halogen-free. Among organic flame retardants, brominated flame retardants have certain advantages in many aspects, but they have always caused heated discussions among environmental experts. In the halogen-free flame retardant system, red phosphorus can be regarded as an excellent role. It has the advantages of small addition amount, good flame retardant effect, wide application range and good environmental protection effect.
