由于其优异的性能,环氧树脂(ER)在工业中的广泛使用与全球向更绿色资源和节能解决方案的转变相一致,在3D打印聚合物部件中使用金属氧化物可以在不同行业提供扩展的功能。氧化锌在聚氨酯-丙烯酸酯复合材料中的含量影响DLP样品的附着力和厚度,1wt.%的样品的厚度为3.99±0.16 mm,最接近目标厚度4 mm,而0.5wt.%的样品的平均厚度偏差最小(±0.03 mm)。含有氧化锌的数字光加工(DLP)复合材料的拉应力在23.29 Mpa(1wt.%)到25.93 Mpa(0.5wt.%)之间保持不变,随着氧化锌浓度的增加,拉伸应力降低到24.04 Mpa,在2wt%时弹性模量值降低到2001 Mpa。生产的DLP样品在碱性环境中具有良好的耐腐蚀性,非常适合用作罐壁保护涂料。定制的DLP技术可以有效地将其用作结构或功能元素,例如用于波特兰水泥混凝土墙、地板和天花板,以增强耐用性和性能。
The widespread use of epoxy resin (ER) in industry, owing to its excellent properties, aligns with the global shift toward greener resources and energy-efficient solutions, where utilizing metal oxides in 3D printed polymer parts can offer extended functionalities across various industries. ZnO concentrations in polyurethane acrylate composites impacted adhesion and thickness of DLP samples, with 1 wt.% achieving a thickness of 3.99 ± 0.16 mm, closest to the target thickness of 4 mm, while 0.5 wt.% ZnO samples exhibited the lowest deviation in average thickness (±0.03 mm). Tensile stress in digital light processed (DLP) composites with ZnO remained consistent, ranging from 23.29 MPa (1 wt.%) to 25.93 MPa (0.5 wt.%), with an increase in ZnO concentration causing a reduction in tensile stress to 24.04 MPa and a decrease in the elastic modulus to 2001 MPa at 2 wt.% ZnO. The produced DLP samples, with their good corrosion resistance in alkaline environments, are well-suited for applications as protective coatings on tank walls. Customized DLP techniques can enable their effective use as structural or functional elements, such as in Portland cement concrete walls, floors and ceilings for enhanced durability and performance.
