发布时间：2018-08-17 16:21
【摘要】：光固化是一种快速、高效且低能耗的固化手段,在诸多领域具有重要应用价值。光固化过程中易产生固化收缩,较快的交联速度导致收缩应力难以释放,显著影响材料的尺寸精度、力学性能及使用稳定性,这些不足引起了众多研究学者的关注。文中综述了光固化收缩产生的原因和主要影响因素,详细介绍了近年来有效降低收缩程度的技术手段和方法,具体实施效果及目前仍然存在的问题,为光固化进一步的研究提供参考。
[Abstract]:Light curing is a fast, efficient and low energy consumption curing method, which has important application value in many fields. Curing shrinkage is easy to occur in the process of light curing, and the shrinkage stress is difficult to be released due to the rapid crosslinking speed, which significantly affects the dimensional accuracy, mechanical properties and application stability of the materials. These shortcomings have attracted the attention of many researchers. In this paper, the causes and main influencing factors of photocurable shrinkage are summarized, and the technical methods and methods of reducing shrinkage degree in recent years are introduced in detail, the concrete implementation effect and the existing problems are introduced in detail. It provides a reference for the further study of light curing.
