OXETANE-MODIFIED ISOCYANURATE, PREPARATION METHOD THEREFOR, ENERGY CURABLE COMPOSITION AND USE THEREOF

WIPO Patent Application WO/2022/135348

A1

Provided are an oxetane-modified isocyanurate, a preparation method therefor, an energy curable composition and the use thereof. The preparation method comprises: carrying out a first polymerization reaction on raw materials a and b to obtain a first polymerization product system; carrying out a second polymerization reaction on the first polymerization product system and a raw material c to obtain oxetane-modified isocyanurate. Since the rings in the above-mentioned oxetane compounds have a similar ring strain and higher alkalinity, and exhibit a longer induction period and a low degree of bulk polymerization, same also have the characteristics of a low shrinkage percentage during curing and excellent mechanical properties, heat resistance, weather resistance and transparency. The modification of isocyanurate by using oxetane compounds with the above-mentioned structure is beneficial for improving the curing properties, hardness, heat resistance and weather resistance of isocyanurate. In addition, the modified isocyanurate has better adhesion to the substrate after curing due to the introduction of heteroatoms.
