Diatomite is a kind of siliceous sedimentary rocks formed by remains of single-celled algae under natural conditions
which is widely used in chemical
petroleum
building materials
biological medicine and health care and environmental protection
and many other fields because of its light weight
large specific surface area
strong adsorption
sound insulation
wear resistance
heat resistance
and corrosion resistance characteristics etc. However
due to the similar structure and composition of diatomite and silica
the silica is usually used as rubber reinforcing filler
at present
the research on the application of diatomite in rubber reinforcing filler is seldom reported. In the present paper
the properties of diatomite
research status at home and abroad
the modification of diatomite and the preparation process of diatomite reinforced rubber composites was summarized. And the development trend of diatomite reinforced rubber composites was previewed.
