Abstract

The invention belongs to the technical field of chemical materials and discloses a porous volatile organic compound absorbing calcium carbonate-kaolin composite material and a preparation method thereof. An applied preparation system comprises a grinding module, a stirring module, a centrifugal dewatering module, a drying module, a cold pressing module and a sintering module. The porous volatile organic compound absorbing calcium carbonate-kaolin composite material enhances cladding property of styrene around calcium carbonate composite particles and adherence of the styrene onto the surface of calcium carbonate, and meanwhile, through organic bentonite, can further enhance the lubricating, waterproof and thermal-resisting performance of the calcium carbonate and broaden application of thecalcium carbonate in industry. Besides, by means of the auxiliaries of methyltriethoxysilane, zirconium fluoride, quartz powder and basswood ash, the porous volatile organic compound absorbing calcium carbonate-kaolin composite material can greatly improve the breaking elongation and the tensile strength compared with unmodified calcium carbonate filled polytetrafluoroethylene composite materials.

Description

technical field [0001] The invention belongs to the technical field of chemical materials, and in particular relates to a multi-void calcium carbonate kaolin composite material for absorbing organic volatiles and a preparation method thereof. Background technique [0002] Calcium carbonate is an inorganic compound, commonly known as: limestone, limestone, stone powder, marble, etc. Main ingredient: Calcite, chemical formula is CaCO 3 , Neutral, basically insoluble in water, soluble in hydrochloric acid. It is a common substance on the earth and exists in aragonite, calcite, chalk, limestone, marble, travertine and other rocks, and is also the main component of animal bones or shells. Calcium carbonate is an important building material and is widely used in industry. Calcium carbonate is formed by combining calcium ions and carbonate ions, so it is both a calcium salt and a carbonate. However, the calcium carbonate used in the existing calcium carbonate composite material...
