| Abstract_FL | The styrene-butadiene rubber (SBR) was filled respectively with tubular halloysite, flaky sericite and their mixture which were modified with silane coupling agent, and the effects of different forms of minerals on the mechanical properties of rubber were investigated.The results showed that halloysite was helpful to improvement the tensile strength, sericite could improved the tear strength and stretching stress of vulcanizates.Under the conditions of filling amount of 80 phr and the mass ratio of halloysite/sericite at 7/3, the reinforcement effect caused by mixed fillers was complement and mechanical properties of composite increased significantly, the tensile strength , modulus at 300%, elongation at break and tear strength reached 11.38 MPa, 4.32 MPa, 847%, 34.55 kN/m respectively.The results analyzed by Fourier transform infrared spectroscopy and scanning electron microscope indicated that the modifier adsorbed on the surface of the mineral, which enhanced the compatibi-lity between the mineral powder and the rubber matrix;the tubular halloysite interspersed between the sericite layers and the two minerals packing densely, two different forms of minerals could enhance their own advantages each other, and could synergistic reinforce SBR. |
