STUDY ON PROPERTIES OF A HYBRID UV-CURABLE PREPREG FOR OIL TANKS

Abstract

Abstract: The factors affecting hybrid UV prepreg were analyzed. The test proved that the curing thickness of the prepreg was positively correlated with the concentration of thermal initiator. When the concentration of thermal initiator (BPO) added was 1.0%, the maximum curable depth was 30.4 mm. When the concentration of thickener (MK 35) was 1.5%~2.0%, the thicking curve was most suitable. The properties between traditional UV prepreg and hybrid UV prepreg were compared. The test proved that the mechanical properties were comparable, while one-time curing depth of hybrid UV prepreg was 120.3% higher than traditional UV prepreg, which solves the problem of limited thickness of UV prepreg.

Key words: UV curing resin, photoinitiator, thermal initiator, hybrid UV prepreg, tank lining modification
