Molecular sieve has many bizarre but excellent physical and chemical properties for its quantum size effect and interface coupling effects. Over the past decade,molecular sieve has been applied into material fire-retardation research areas. Based on the brief introduction of types,functions and characteristics of molecular sieve,the paper analyzed the application research of molecular sieve applied into material fireretardation,and concluded that molecular sieve is a good flame retardant synergist and adding a small amount molecular sieve could improve the fire-retardation effect. Introducing ...
