Flame retardants are functional auxiliaries that impart flame retardancy to the material. At present, among the many flame retardant types, the development of non-halogenated and low-harmful flame retardants has attracted the most attention. This has led to a rapid increase in the consumption of inorganic flame retardants including magnesium hydroxide and aluminum hydroxide, and metal oxidation. The development of species and application technologies of other chemicals and other synergistic agents has also gradually deepened. In recent years, the application research and development speed of ultra-fine, synergistic, and multi-functional inorganic flame retardants has been accelerated at home and abroad.
At present, the United States is the country with the largest production of magnesium hydroxide and the largest variety of products. There are 14 types of magnesium hydroxide used for different purposes, and 10 types are used for fire-retardant use. In 1996, the production capacity of magnesium hydroxide in the United States was 395,000 tons. It was produced by 9 plants of 6 major companies. The total amount of magnesium hydroxide used as flame retardant was about 1.5-2.0 million tons. At present, there are eight major Japanese manufacturers. In 1996, the production capacity of magnesium hydroxide in Japan was 460,000 tons. In 1995, the amount was 385,000 tons. Among them, flame-retardant grade magnesium hydroxide has nearly 10 varieties, and the output is about 14,000 tons. In addition to domestic use in Japan, there are exports. In Western Europe, 9 manufacturers in 7 countries produce magnesium hydroxide. In 1996, the total capacity exceeded 520,000 tons, and some of them were equipped with flame-retardant grade magnesium hydroxide production lines. According to data, in 1995, the consumption of flame retardant in all countries in Western Europe was 260,000 tons, and the inorganic added flame retardants, aluminum hydroxide and magnesium hydroxide, accounted for about 48%, of which magnesium hydroxide still showed a momentum of growth. The growth rate is about 6-8%. China's flame retardant research began in the mid-1960s. In 1993, the total demand was 10 to 12 million tons. In 1998, the production capacity of magnesium hydroxide in China was estimated to be about 1 to 1.2 million tons of production, which is not ranked in the international rankings. The resources of magnesium hydroxide production in China have undisputed advantages compared with Japan and are comparable to those of the United States. These conditions are very favorable for the development of magnesium hydroxide flame retardants.
In recent years, the annual growth rate of magnesium hydroxide flame retardant is 8%, and this level is still maintained. The annual growth rate in 2005 is 1O-20%. If the halogen-based flame retardant is limited, its growth rate will be higher. Relevant experts believe that the flame retardant market in Europe has matured, and the relevant legislation concerning fire safety is already established, and these are all favorable for research, development, production and application of flame retardant chemicals.
With the development of science and technology and the urgent requirements of the Green Earth project, people gradually favor new non-toxic, smoke-inhibiting magnesium hydroxide flame retardants. According to experts' estimation, the demand for such flame retardants increases at an annual rate of 8%. Japanese companies are developing seawater-halide magnesium hydroxide flame retardants while focusing some attention on the comprehensive utilization of brucite. While actively developing synthetic magnesium hydroxide flame retardants, the United States has also devoted considerable attention to the process of producing flame retardants for the processing and utilization of natural resources brucite.
With the development of China's polymer industry, the demand for magnesium hydroxide flame retardants is increasing substantially. Regardless of the magnesium hydroxide produced from synthetic resources or natural resources, the use of flame retardant is increasing day by day. Using China's abundant magnesium resources, relying on technological innovation to develop high value-added flame-retardant magnesium hydroxide is the face of the magnesium salt industry. A common topic. Among magnesium-based products, flame-retardant magnesium hydroxide, especially high-purity magnesium hydroxide, is uniquely attractive due to its large market potential at home and abroad. China's natural brucite resources have been mined and applied, and the amount of mineral reserves is relatively abundant. Making full use of these resources to actively develop magnesium hydroxide flame retardants is a promising task with great potential.
