Transparency- and Repellency-Enhanced Acrylic-Based Binder for Stimuli-Responsive Road Paint Safety Improvement Technology

Abstract

In the current study, an acrylic polymer binder applicable to road signs was successfully developed by mixing various acrylic, acrylate-type, and photoinitiator-based monomer species at different acrylate series/silicone acrylate ratios. An amorphous acrylic monomer was used, and the distance between the polymers was increased to improve transparency. The binder was designed with the purpose of reducing the yellowing phenomenon due to resonance by excluding the aromatic ring structure, which is the main cause of yellowing. The optical properties of the binder were determined according to the content of n-butyl methacrylate/methyl methacrylate and the composition of the crosslinking agent in the formulation. Allyl glycidyl ether and dilauroyl peroxide were used to improve the yellowing problem of benzoyl peroxide, an aromatic photoinitiator. Adding a silicone-based trivalent acrylic monomer, 3-(trimethoxysilyl)propyl methacrylate (TMSPMA), was also found to have a significant effect on the transparency, shear properties, and water resistance of the binder. When 15 wt% TMSPMA was added, the best water repellency and mechanical properties were exhibited. The surface morphology of the improved binder and the peeling part were confirmed using field emission scanning electron microscopy. The acrylic polymer developed in this study can be applied in the coating and adhesive industries.

The effect of acrylic silane crosslinker on room‐temperature cured acrylate binder for road markings

“…The effect of silicone‐based acrylate TMSPMA on the properties of an acrylic resin series is evaluated as a function of TMSPMA concentration. Figure 2 shows the tensile and shear strength of an acrylic resin series on the different existence of a TMSPMA crosslinker 28 . As TMSPMA content in the crosslink network increases, tensile strength increases up to a limiting value of 10 wt% and then decreases.…”

Formation of optimum network structure may stiffen the acrylic resin binder and cause improvement in tensile strength.…”

Synthesis of Room Temperature Curable Polymer Binder Mixed with Polymethyl Methacrylate and Urethane Acrylate for High-Strength and Improved Transparency

“…An optimized polymer binder was prepared by adjusting the PMMA to UA ratio while the content of the initiator and reaction promoting catalyst was fixed. In future studies, it will be mixed with luminescent paint and used as a promising photo-stimulation smart, sensitive material [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58].…”

Synthesis of a Room-Temperature Curable Acrylic-Urethane Polymer Binder for Road Markings with High Transmittance

“…Acrylic-urethane binders could be employed to provide high-performance marking paints [ 12 , 19 , 20 , 21 , 22 ]. They must offer high transparency, hydrophobicity, toughness, and adhesion for used in acryl resin-based marking paint with outstanding durability and protective properties [ 23 , 24 ]. The basic formulations used in acrylic-urethane are acrylic monomers, soft blocks of polyols, and hard blocks of diisocyanates [ 25 , 26 , 27 ].…”
