Study on Reinforcement of Diatomite/Silica Composite Filler

Abstract

Abstract: In order to expand the application of diatomite in polymer composites, the composite material was prepared by diatomite/silica composite filler into natural rubber/styrene butadiene rubber/butadiene rubber (NR/SBR/BR). The Payne effect and dispersion of the composite fillers were analyzed by RPA2000 and SEM. The effects of diatomite content on the technological properties, mechanical properties, and wear resistance of the composites were investigated. The results show that the addition of a small amount of diatomite is beneficial to the dispersion of silica in rubber, reduce the Mooney viscosity and Payne effect of the composite material, improve the curing speed and shorten the curing time, and thecomposite filler has better reinforcement effect. The composite filler is easy to aggregate and the mechanical properties of the composites are decreased, the wear properties are changed little when the amount of diatomite is increased. The composite material has the best comprehensive performance when the diatomite dosage is 10~20 phr.

Key words: diatomite, silica, natural rubber, Payne effect, reinforcement, composite
