Abstract: This paper presents the effect of coupling agent on the mechanical properties of flameretardant high impact polystyrene(HIPS), Fire retarding HIPSis usually used with a certain amount of SiO2 as the filler.To improve the properties of HIPS/SiO2 composite material, coupling agent was used to reinforce the surface interaction between HIPSand SiO2. It was found that the concentration of coupling agent strongly affected the mechanical properties of HIPS/SiO2. There existed a critical concentration of coupling agent, at which the properties of HIPS/SiO2 composite material was enhanced apparently.Results obtained from electron microscope showed that after using coupling agent to treat the surface of SiO2, the interface microstructure of HIPS/SiO2 was changed, The mechanical properties of the HIPS/SiO2 can be improved by adding the coupling agent to this system.
