Study on the synergistic flame retardant effect of brucite powder in chlorinated polyethylene rubber
Brucite powder, as an efficient halogen-free flame retardant, has great potential in improving the flame retardant properties of chlorinated polyethylene (CPE) rubber. This study aims to outline the synergistic flame retardant mechanism of brucite powder in CPE rubber and its optimized application.
Characteristics of brucite powder
Flame retardant mechanism: decomposes at high temperature, produces water to absorb heat, and the generated magnesium oxide forms a protective layer, effectively isolating oxygen and heat.
Environmental protection: non-toxic, halogen-free, meeting modern environmental protection standards.
Compatibility improvement: improve compatibility with polymer matrix through surface modification technology.
Application of synergistic flame retardants
Used in conjunction with flame retardants such as phosphate, zinc borate, and zinc oxide to enhance the flame retardant efficiency and mechanical properties of CPE rubber.
