摘　　要：相比于传统的热固性树脂,光固化树脂是一种分子量较低的感光树脂,可在紫外光照射下迅速发生物理和化学变化,具有能源利用率高、固化放热低的特点。因此提出了一种甲基丙烯酸苹果酸酯光固化树脂的制备方法,利用DL-苹果酸多官能团的优点将甲基丙烯酸接枝在树脂的侧链,并研究了DL-苹果酸不同含量对树脂性能的影响。合成的树脂在侧链含有不饱和双键,树脂添加光引发剂后在光照下可以短时间内固化。由于苹果酸在架构上与丁二酸相接近,所以合成的树脂具有优异的力学性能,断裂伸长率可达38.52%,断裂强度可达19.25 MPa,是一种性能优异的光固化树脂。Compared with the traditional thermosetting resin,light curable resin is a photosensitive resin with low molecular weight.It can change rapidly in physics and chemistry under UV irradiation.It has the characteristics of high energy utilization and low heat release.Therefore,we proposed a preparation method of synthesizing methacrylate malate light curable resin.Using the advantages of DL-malic acid multifunctional group,methacrylic acid was grafted on the side chain of the resin,and the effects of different content of DL-malic acid on the properties of the resin were studied.The synthesized resin contains unsaturated double bonds in the side chain.After adding photoinitiator,the resin can be cured in a short time under light.Because malic acid is close to succinic acid in structure,the synthesized resin has excellent mechanical properties,the elongation at break can reach up to 38.52%,and the breaking strength can reach up to 19.25 MPa.
