Industrial 3D abrasive paper is abrasive paper with a certain pattern. It can be obtained by cross-linking polymerization of lightor heat-curable resins with the addition of abrasives such as aluminum oxide and silicon carbide. The purpose of this abrasive paper can vary depending on the pattern, and the most common pattern among 3D abrasive papers is a triangular pyramid shape, which has excellent grinding sustainability and allows for uniform grinding surface processing. Abrasive paper lacking a pattern exhibits limitations in its application, primarily confined to the initial surface processing stage, characterized by irregular polishing performance and substantial surface roughness values. To overcome these challenges and enhance the efficiency of finishing work in the grinding process, patterned abrasive paper has been developed. The introduction of specific patterns addresses the shortcomings associated with non-patterned abrasive paper, allowing for more effective and precise outcomes in subsequent stages of the grinding process. These patterned abrasive papers can minimize initial scratches and is excellent for final polishing, so it is mainly used in the final defect removal process after top coating on automobiles.This study was conducted to manufacture industrial 3D abrasive paper using a light-curing method and improve performance through heat treatment. The resin used in the study was manufactured as a dual curing type using monomers such as 2-HEA (2-hydroxyethyl acrylate), DPPA (Dipentaerythritol pentaacrylate), and PETA (Pentaerythritol triacrylate), which have an acrylate functional group and a hydroxy functional group in one molecule, and IPDI (Isophorone diisocynate), an isocyanate series that can create crosslinks to the hydroxy functional group. As a comparison group to compare with this, a UV-only curing type abrasive paper was produced, and the resins used were TPGDA (Tripropylene glycol diacrylate), DPHA(Dipentaerythritol hexaacrylate), and PETTA (Pentaerythritol tetraacrylate) monomer. Photoinitiators BIS (2,4,6-Trimethylbenzoyl) phenyl phosphine oxide and 2,4,6-Trimethylbenzoyl-diphenyl phosphine oxide were added to each resin mixture, and resin was filled with GC#3000 abrasives. And BYK-145 used as a dispersant to disperse GC#3000 abrasive. The prepared polishing slurry was used to transfer the 3D pattern in relief using a soft mold with a triangular pyramid-shaped pattern engraved in engraving to create an abrasive paper film. Then, this film was cured with UV and heat to produce 3D pattern abrasive paper.Through SEM analysis, it was confirmed that the patterned abrasive paper had hardened into a sure triangular pyramid shape, and through DSC measurement, polishing evaluation, and surface roughness measurement evaluation, it was confirmed that the internal curing rate of the dual curing type abrasive paper was increased and the performance was improved.As a result of TGA, it was confirmed that the abrasive paper cured using the dual curing method was thermally stable by UV and heat curing, and that the heat generated during sanding did not affect the resin performance of the abrasive paper.
