摘　　要：通过改性得到具有光固化活性端丙烯酰基聚丁二烯(PBAC).将PBAC作为光敏树脂的低聚物与稀释剂甲基丙烯酸异冰片酯(IBOA)、丙烯酸异癸酯(IDA)及光引发剂复配,通过光固化动力学确定最高效含量引发剂,并讨论不同稀释剂IBOA与IDA的相对含量对UVPB树脂力学性能、黏度、固化体积收缩率的影响,发现低聚物PBAC为1.44 mmol,稀释剂IBOA含量为49mmol,IDA含量为35mmol,光引发剂含量为5.5mol%时,UVPB树脂的性能较好,最终得到可用于SLA3D打印的传统型光敏树脂.In this paper,photocurable active-terminated acryloyl polybutadiene(PBAC)was obtained by modification.The PBAC as photosensitive resin of oligomer and diluent bornyl acetate(IBOA)methyl acrylic acid,acrylic isodecyl ester(IDA)and light initiator distribution,the most efficient content was determined by UV curing kinetics initiator and the relative content of different diluents IBOA and IDA to UVPB resin mechanical properties,viscosity,curing the influence of the volumetric shrinkage was discussed.It is found oligomer PBAC 1.44 tendency,diluent IBOA content is 49 tendency,IDA content of 35 tendency,light initiator content is 5.5 mol%,The performance of UVPB resin is better,and finally the traditional photosensitive resin can be used for SLA 3D printing.
