Acrylic cyclooxide soybean oil-based UV curing coating

In a new study, a series of high-energy acrylics with triglyceride rings as rigid cores and long fat chains as soft arms were synthesized, and then added these synthetic acrylics to acrylic ecyclic soybean oil (AESO) to prepare coatings that can be cured by ultraviolet light.
high-function soybean oil-based acrylates showed more comprehensive performance than commercial petroleum-based acrylates with similar structures.
the chemical structure and molecular weight of acrylics are indicated by Fourier transforming the infrared spectrum, the nuclear magnetic resonance and gel permeation chromatography, and the curing behavior

of the coating is studied using real-time infrared spectroscopy.
results of stretch testing, dynamic thermodynamic analysis and thermal weight analysis show that the addition of high-functional acrylics significantly improves the thermal and mechanical properties of UV curing membranes compared to pure AESO.
improves the performance of AESO-based UV curing coatings
in addition, the hardness of AESO-based UV curing coatings is improved with the addition of high-function bio-based acrylics. High-function bio-based acrylates have higher bio-based content and show more comprehensive performance than commercial petroleum-based acrylates with similar structures.
