摘　　要：本文通过丙烯酸酯改性处理石墨,然后填充到到天然橡胶中,研究胶料的导热性。研究结果发现:天然橡胶填充经过丙烯酸酯改性处理的石墨后,硫化胶的导热率明显改善,同时胶料的力学强度也有提高。在所研究的两种配方中,当石墨和改性总单体的质量比为5∶1时,胶料的力学性能和导热性最好。In this paper the thermal conductivities and mechanical properties of natural rubber which was filled with graphite modified by acrylate were studied experimentally. It is shown that the thermal conductivities of vulcanizates are improved significantly. At the same time, mechanical properties are increased. When the mass ratio of graphite to monomers is 5：1, the thermal conductivity and mechanical properties of natural rubber are highest.
