用于激光快速成型的光固化树脂组合物及其制备方法
摘要：
本发明涉及一种用于激光快速成型的光固化树脂组合物及其制备方法。一种用于激光快速成型的光固化树脂组合物，以质量百分含量计包括以下组分：30.0％～80.0％的低聚物树脂、15.0％～60.0％的活性稀释剂、1.0％～10.0％的光引发剂、1.0％～5.0％的无机颜料、0.1％～5.0％的有机颜料及0.01％～2.0％的分散剂。上述用于激光快速成型的光固化树脂组合物通过各组分之间的相互作用，促使无机颜料表面快速润湿，极大地抑制无机颜料颗粒间的相互聚集，最大化保持无机颜料的初级粒径，降低无机颜料的沉降速率，进而有效保障用于激光快速成型的光固化树脂组合物优越的储存稳定性及其良好的机械性能。
摘要（英）：

The invention relates to a photocurable resin composition for laser rapid prototyping and a preparation method thereof. The photocurable resin composition for laser rapid prototyping comprises the following components in percent by mass: 30.0-80.0% of oligomeric resin, 15.0-60.0% of an active diluent, 1.0-10.0% of a photoinitiator, 1.0-5.0% of an inorganic pigment, 0.1-5.0% of an organic pigment and 0.01-2.0% of a dispersing agent. Through interaction among the components of the photocurable resin composition for laser rapid prototyping, quick wetting of the surface of the inorganic pigment is promoted, mutual aggregation of inorganic pigment particles is greatly inhibited, the primary particle size of the inorganic pigment is maintained to the maximum extent, the sedimentation rate of the inorganic pigment is reduced, and further excellent storage stability and good mechanical properties of the photocurable resin composition for laser rapid prototyping are effectively guaranteed.
