Surface Modification of Brucite and its Application in Flame Retardant Polypropylene Composites

Article Preview

Abstract:

The surface modification of superfine brucite using silane coupling agent as a modifier was studied. The results of the best modified conditions show that the treated time is 1.5h, the treated temperature is 40°C, the content of silane coupling agent is 7wt%,the stirring speed is 600r/min. In this condition, the activation index up to 93.5%; the treated brucite particles filled into polypropylene(PP), the best tensile strength of 28.63MPa and the LOI of 30% is measured.
