With the development of polymer material industry, fiber, resin, chemical, construction, transportation, rubber and other synthetic materials are more and more, electronics and other industries.However, most polymers are easily combustible materials, and in many applications, flame retardants need to be added to polymer materials to prevent fire, and they must also be added to adhesives.Magnesium hydroxide is an important inorganic flame retardant, good thermal stability, no volatilizing, no precipitation, no toxic gas, no pollution, opium significant and many other advantages of destruction, is a green flame retardant, widely used in plastics, rubber, flame retardant and smoke and resin polymer materials.But it is a compound with high surface polarity, agglomeration between particles is serious, and the compatibility with the polymer is poor, adding physical mechanics yan Ying polymer performance assembly, processing performance deterioration amount, in actual use, often need to modify magnesium hydroxide.

  The commonly used modification methods include: surfactants or coupling agents, surface grafting, intercalation, microencapsulation, ultrafine method, magnesium hydroxide whisker and so on.These systems of modified magnesium hydroxide flame retardants, applied to adhesives, can be used alone or with other substances adsorbed aluminum hydroxide for better results.Through different bonding experiments specific addition and ratio, production and experimental data and other real life has a great help.

  Flame retardants are mainly used in transportation, electrical and electronic equipment, furniture and building materials.Adding flame retardants doesn't make the material completely fire-resistant, but it can still reduce the number of fires and buy people valuable time to escape.In the fire space, due to the accumulation of flammable gas and heat, there may be a "flash" phenomenon - all kinds of flammable substances in 1 to 2 seconds at the same time fire.The emergence of flame retardants can effectively avoid this situation.In the case of cathode-ray tube televisions with plastic shells, the escape time is less than two minutes if they are not flame-retardant, but with the help of flame retardants, the escape time can be increased to more than 30 minutes.

  The role of flame retardants in fire safety has been proven.The European Commission estimates that the use of flame retardants has reduced the number of fire deaths in Europe by 20 percent over the past 10 years.A 2009 study by Greenstreet Berman, conducted by the British government, found that between 2002 and 2007, after the Furniture and Furnishings Fire Safety Regulations were enacted, there were 54 fewer fire deaths per year, 780 fewer non-fatal burns per year and 1,065 fewer fire accidents per year. And the fireproof processing of furniture also cannot leave flame retardant.
