Estimating the term…
This invention relates to a method for producing 3D printing material. The method involves first producing, from at least one photocatalyst and at least one phyllosilicate, a photocatalyst-phyllosilicate composite; From the photocatalyst-phyllosilicate composite and at least one thermoplastic polymer, a photocatalyst-phyllosilicate-polymer composite is then produced. Finally, the photocatalyst-phyllosilicate-polymer composite is subjected to a shaping process, producing a 3D printing material. This invention also relates to a 3D printing material comprising a thermoplastic matrix and, embedded in the matrix, a composite material containing at least one photocatalyst and at least one phyllosilicate. This invention further relates to a method for producing components from the 3D printing material and a component produced using this method.
A 3D printing material comprising at least one thermoplastic matrix polymer and embedded in the at least one thermoplastic matrix polymer, a composite material containing at least one photocatalyst selected from the group consisting of TiO2, ZnO, SnO2, WO3, Fe2O3, Fe3O4, MnO, NiO, and mixtures thereof, and at least one phyllosilicate selected from the group consisting of hectorite, bentonite, montmorillonite, muscovite, illite, kaolinite, halloysite, palygorskite, vermiculite, and mixtures thereof, wherein the 3D printing material is in a form of a granulate, a filament, or rods, and the 3D printing material contains 10 to 60 weight % of the at least one photocatalyst and 5 to 40 weight % of the at least one phyllosilicate, relative to the total weight of the 3D printing material.
