【Abstract】 Sepiolite is surface modified with surfactants. Effects of surfactant types and the dosage of sepiolite on the thermal properties of unsaturated polyester composites are investigated by DTA analysis. The optimum quantity of sepiolite in the unsaturated polyester composite is explored. Experimental results show that the thermal properties of unsaturated polyester matrix composite can be improved through adding sepiolite, and the sepiolite modified with cationic surfactants has a better reinforcement effect than that with anionic ones. The composite has the best heat-resistant property when the content of sepiolite is about 8-11 percent.更多还原
