In the textile industry, with the increasing demand for high-performance flame retardant fibers, the synthesis of new high-performance flame retardants provides an ideal material for the development of functional fabrics. Nano magnesium oxide is often used together with wood chips and shavings to manufacture lightweight, soundproof, heat-insulating, fire-resistant fiberboard and other refractory materials, as well as metal ceramics. Compared with traditional organic flame retardants containing phosphorus or halogens, nano magnesium oxide is non-toxic, odorless, and has a small amount of addition, making it an ideal additive for developing flame retardant fibers. In addition, nano magnesium oxide has strong cleaning and corrosion inhibition capabilities for fuel, and has good application prospects in coatings.
