Sepiolite-acrylic ester compound light curing material, and preparation method thereof

The invention belongs to the technical field of light curing material, and more specifically relates to a sepiolite-acrylic ester compound light curing material, and a preparation method thereof. The sepiolite-acrylic ester compound light curing material is composed of acrylic ester, sepiolite modified via surface treatment, a photosensitizer, and a photoinitiator. The preparation method comprises following steps: a coupling agent is added into dried sepiolite at a certain mass ratio, and an obtained mixture is subjected to mechanical grinding; sepiolite modified via surface treatment is added into a mixture of acrylic ester, the photosensitizer, and the photoinitiator, and an obtained mixed material is subjected to mechanical stirring. Curing molding of the sepiolite-acrylic ester compound light curing material can be realized under irradiation of light with a wavelength of 405 nanometers, and the color of the appearance is gray. The sepiolite-acrylic ester compound light curing material can be applied to DL
