环氧树脂基混凝土作为一种绿色环保的建筑材料,在道路修补和保温建筑中应用广泛。以环氧树脂E44为原料,二甲苯为稀释剂,纳米玻璃纤维为填料,制备了复合环氧树脂基混凝土,研究了不同纳米玻璃纤维长度对混凝土微观形貌、力学性能和保温性能的影响。结果表明,纳米玻璃纤维的掺杂发挥了“晶种”作用,促进了水化反应的进行,提高了环氧树脂基混凝土的密实度。纳米玻璃纤维长度的适当增加提高了混凝土与纤维的结合强度,当纳米玻璃纤维长度为8 mm时,混凝土的形貌最佳。随着纳米玻璃纤维长度的增加,混凝土的抗压强度和抗折强度先增大后降低。养护28 d,当纳米玻璃纤维长度为8 mm时,混凝土的抗压强度和抗折强度均达到最大值,分别为21.93和4.59 MPa。纳米玻璃纤维的掺杂改善了混凝土的孔结构,降低了导热系数,提高了保温性能,当纳米玻璃纤维长度为8 mm时,混凝土导热系数最低为0.147 W/(m·K),保温性能最佳。

Lubricants are often contaminated by water in different ways. Water-polluted lubricants extremely accelerate wear corrosion, leading to the deterioration of lubricity performance. Recently, multiphase media superwettability has been developed to endow one surface with compatible functions, such as on-demand separation of oily wastewater. However, realizing the robustness of the dual superlyophobic surface to solve water-caused lubricant deterioration and water contamination as needed remains challenges. Herein, a robust dual superlyophobic membrane is presented to realize on-demand separation for various lubricant–water emulsions. Compared to pure lubricants, the purified lubricants have equivalent tribology performance, which are much better than that of water-polluted lubricants. The as-prepared membrane maintains dual superlyophobicity, high-efficient for water or lubricant purification, and excellent tribology performance of the purified lubricant, even after immersion in hot liquids for 24 h, multicycle separation, and sandpaper abrasion for 50 cycles. Water-polluted lubricant extremely accelerates wear corrosion to promote catalytic dehydrogenation of lubricants, generating too much harmful carbon-based debris. This work shows great guiding significance for recovering the tribology performance of water-polluted lubricants and purifying water by the dual superlyophobic membrane.
