Novel bio-based/inorganic micro-nano composite fiber material as well as preparation method and application thereof
The invention provides a bio-based/inorganic micro-nano composite fiber material which comprises one or two of an unbleached paste-aragonite type calcium carbonate-white carbon black composite fiber material or an unbleached paste-calcite type calcium carbonate-white carbon black composite fiber material, the preparation method comprises the following steps: mixing and suspending cement and/or cement clinker and unbleached paste in an aqueous solution, introducing carbon dioxide or flue gas at 25-100 DEG C under stirring and mixing conditions, and carrying out neutralization precipitation, double decomposition and dehydration condensation reaction for 0.5-15 hours under stirring to synthesize the bio-based/inorganic micro-nano composite fiber material. The composite fiber material has the remarkable cost performance advantages of being low in production cost, small in density and heat conductivity coefficient and easy to disperse, the tensile strength and elasticity modulus of plastic can be greatly improved, and the cost performance advantages of quality improvement and cost reduction are remarkable; the method has huge application potential in the fields of reinforcement, toughening, cost reduction, light thermal insulation materials and the like in plastics, papermaking, coatings, asphalt, rubber and concrete.
