For the safety of people’s lives and property, the development of flame retardants should focus on the following aspects:
(1) environmental friendliness
In order to meet the needs of environmental protection, it is necessary to strengthen the development of halogen-free, high-efficiency, low-smoke and low-toxic flame retardants and the research on flame retardant technology. From the perspective of the development prospect of flame retardants, halogen-free flame retardants, organosilicon flame retardants, microcapsules and nano-level flame retardants have provided the possibility for the green products. At the same time, non-toxic and harmless raw materials, solvents and catalysts should be used in production.
(2) improvement of flame retardant technology
Halogen-free flame retardants, especially inorganic flame retardants, the finer the particle size, the faster the thermal decomposition, the better the flame retardant effect, and the better the dispersion and compatibility with the polymer. In recent years, the emerging nanomaterials, such as nano-sio2 and nano-hydroxides, have a variety of characteristics, such as quantum size effect, small size effect, macroscopic quantum tunneling effect and surface effect, due to the extremely small size of nano-particles.
The application of microencapsulation technology in flame retardants is a new technology which has been developed in recent years. Microencapsulation prevents the direct contact between the flame retardant and the material, improves the compatibility between the flame retardant and the flame retardant material, prevents the migration of flame retardant, improves the moisture resistance, flame retardant effect and thermal stability.
Synergistic compound flame retardant
When choosing flame retardants, more compound flame retardants should be developed. Mixing different flame retardants can improve the performance of flame retardants and reduce the amount of flame retardants. It can not only reduce the price of flame retardant, but also reduce the loss of physical and mechanical properties of flame retardant materials.
(3) multi-functional finishing agent
At present, in metallurgy, forestry, chemical, petroleum and fire departments, flame retardant protective clothing is in great demand, but the single flame retardant performance can not meet many special requirements. The multifunctional flame retardant finishing agent can improve the other properties of flame retardant products.
