Abstract

The invention discloses a colorless and transparent light-cured 3D printing material and belongs to the technical field of cured materials. The printing material comprises organopolysiloxane containing a vinyl group, organopolysiloxane containing a silicon-hydrogen bond, a photoinitiator, reinforcing filler and an aid. A preparation method of the material comprises steps as follows: evenly mixing the organopolysiloxane containing the vinyl group, the organopolysiloxane containing the silicon-hydrogen bond, the reinforcing filler and the aid in percentage by mass; then adding the photoinitiator, and evenly mixing the mixture to obtain the colorless light-cured 3D printing material. The printing material has the benefits as follows: (1) the light-cured product is colorless, good in transparency and elastic; (2) the light-cured material is low in molding shrinkage, and the volume shrinkage is lower than 1.0%; (3) all components in a resin mixture participate in curing, no volatile solvent exists, and pollution is avoided; (4) the printing material is high in curing light source applicability, and the maximum curable light wavelength is 405 nm.

Description

technical field

[0001] The invention belongs to the field of curing materials, in particular to a colorless and transparent light-curing 3D printing material and a preparation method thereof. Background technique

[0002] Organosilicon polymers are semi-inorganic and semi-organic polymer compounds with silicon-oxygen bonds as the main chain and side chains through silicon and organic groups. The special structure endows it with many excellent properties, such as high and low temperature resistance, weather resistance, aging resistance, corrosion resistance, low surface tension and physiological inertia. Light curing technology has the advantages of fast curing, low energy consumption, high efficiency, and no pollution. It fully complies with the "3E" principle: Energy (energy saving), Ecology (ecology and environmental protection), and Economy (economy). It is an environmentally friendly green technology. Light-curing silicone materials are favored due to the excellent perf...
