Beschreibung
Zusammenfassung:	The invention discloses a black talc modified photosensitive resin composition for additive manufacturing and a preparation method thereof. The composition is prepared from the following components in parts by weight: 100 parts of an acrylate resin raw material, 2 to 18 parts of a filling agent, 0.5 to 2 parts of a photoinitiator, 0.01 to 0.1 part of a catalyst, 1 to 3 parts of a cross-linking agent, 0.01 to 0.05 part of a light absorbent and 0 to 5 parts of an auxiliary agent, wherein the acrylic ester type resin is prepared from the following raw materials: an acrylic ester monomer, polyester modified epoxy acrylate and aliphatic polyurethane acrylate, the acrylic ester monomer comprises 2-acrylic acid-2-hydroxy-3-phenoxy propyl ester, and the filling agent is modified black talc. The uniform distribution of the filling agent in a contracted polymer skeleton is promoted through modification, so that the shrinkage rate is further reduced. 本发明公开一种黑滑石改性的增材制造用光敏树脂组合物及其制备方法。按重量份数计，所述组合物包括丙烯酸酯型树脂原料100份、填充剂2-18份、光
