Abstract

Sustainable production of efficient and low-cost coating materials from recycled plastic wastes will have a significant impact on economic advancements in paints and coatings, as well as waste management. Polystyrene waste was reduced to a resin, which was further modified by blending with natural rubber latex (NRL). The recycled polystyrene resin (rPS) and NRL formed homogeneous composite resins (rPS-NRL) blends in various ratios, and the changes in some physicochemical properties of the resins were studied. The rPS-NRL blended in different ratios exhibited higher density (0.83–0.92 g/cm3), refractive index (1.401–1.438), viscosity (935–1287 cP), elongation (5–18 %), and melting point (184°C–217.5°C), as well as lower moisture uptake (1.1–0.88 %) and faster drying time (32–19 min), compared to the rPS resin. Changes in functional, structural, and morphological characteristics of the resins were studied using Fourier transformed infrared (FTIR) spectrometer, X-ray diffractometer (XRD), scanning electron microscope (SEM) and thermogravimetric analyzer (TGA-DTA). The results indicated molecular interactions between NRL and the rPS resin, which form the basis for the unique physicochemical properties of the composite resin compared with the pristine rPS and NRL resins. White (CaCO3) pigmented emulsion paint produced using the rPS-NRL composite resin as binder was tested in comparison with paint produced using the conventional polyvinyl acetate (PVA) binder, where the rPS-NRL paint exhibits superior properties, including outstanding resistance to water.

天然胶乳和聚苯乙烯废料复合树脂作为防水乳胶漆配方粘合剂的表征和应用

利用回收的塑料废料持续生产高效、低成本的涂料材料，将对油漆和涂料的经济发展以及废物管理产生重大影响。聚苯乙烯废料被还原成树脂，并通过与天然胶乳（NRL）混合进行进一步改性。再生聚苯乙烯树脂（rPS）和天然胶乳以不同比例形成均质复合树脂（rPS-NRL）混合物，并研究了树脂的一些物理化学特性的变化。与 rPS 树脂相比，以不同比例混合的 rPS-NRL 表现出更高的密度（0.83-0.92 g/cm3）、折射率（1.401-1.438）、粘度（935-1287 cP）、伸长率（5-18 %）和熔点（184°C-217.5°C），以及更低的吸湿率（1.1-0.88 %）和更快的干燥时间（32-19 分钟）。使用傅立叶变换红外光谱仪（FTIR）、X 射线衍射仪（XRD）、扫描电子显微镜（SEM）和热重分析仪（TGA-DTA）研究了树脂的功能、结构和形态特征的变化。结果表明，NRL 与 rPS 树脂之间存在分子相互作用，与原始 rPS 树脂和 NRL 树脂相比，这是复合树脂具有独特理化特性的基础。使用 rPS-NRL 复合树脂作为粘合剂生产的白色（CaCO3）颜料乳胶漆与使用传统聚醋酸乙烯酯（PVA）粘合剂生产的油漆进行了对比测试，结果表明 rPS-NRL 油漆具有优异的性能，包括出色的耐水性。
