Bio-based halogen-free flame retardants have broad prospects and the following advantages and development trends:
Environmental protection and sustainability: Bio-based halogen-free flame retardants are derived from natural materials, are degradable and non-toxic, meet environmental protection requirements, and help reduce pollution to the environment. Under the background of increasingly strict environmental protection regulations at present, bio-based halogen-free flame retardants will become a hot spot in the research of flame retardants in the future.
Performance improvement: By introducing different phosphorus groups into the main chain of vegetable oil to prepare bio-based flame retardants such as phosphorylated flaxseed oil, the flame retardant grade of the material can be effectively enhanced. For instance, when castor oil derivatives containing nitrogen and phosphorus synergistic flame-retardant groups are grafted onto azide-functionalized PVC chains, the LOI value of PVC materials modified by castor oil derivatives can reach 34.7%.
Application field expansion: Bio-based halogen-free flame retardants can be applied in multiple fields such as electronics, automobiles, aerospace, etc., enhancing the safety performance of products. For instance, in the field of electronics, bio-based halogen-free flame retardants are widely used in the manufacturing of materials such as printed circuit boards and electronic components, which can effectively prevent the spread of fire.
Technological innovation and research and development: With the continuous development of biotechnology, more breakthroughs will be made in the research and development of bio-based halogen-free flame retardants. For example, bio-based raw materials can be improved through means such as genetic engineering to enhance their flame retardant performance; Or develop new synthesis processes for bio-based halogen-free flame retardants to reduce costs and improve production efficiency.
