Diopside Used as Rubber and Oil Paint Filler

Because of the special physical properties of non metallic minerals, more and more attentions have been payed to the use of non metallic mineral fillers to modify rubber and plastics and oil paint to obtain new composite materials which not only have special performances, but also have lower costs. Diopside fillers were prepared with the sample from Nanshu, Shandong and Miyun,Beijing. The filling experiments were conducted on styrene butadiene rubber (SBR) and some oil paint with the diopside fillers prepared. The properties of the composite materials filled with the mixture of different amount of diopside and semi reinforcement carbon black are near to those of SBR filled with semireinforcement carbon black only when the quantity of diopside is 20%～30%. When used as oil paint filler, diopside can improve some properties of the oil paint and keep others almost unchanged. This work showed that diopside can be used as SBR filler to accompany with semireinforcement carbon black and as filler for some oil paint.
