摘要:

以高密度聚乙烯(PE⁃HD)为基体树脂,固废漆渣为填充改性剂,硅烷偶联剂(KH⁃560)作为界面改性剂制得漆渣改性PE⁃HD防水板材。研究了漆渣的用量和硅烷偶联剂对聚乙烯防水板材的疏水性能和力学性能的影响。结果表明,漆渣与PE⁃HD共混制得的防水板,其断裂伸长率随着漆渣掺量的增加而显著降低,拉伸强度和接触角度数在漆渣掺量不超过4 %时缓慢增大,漆渣掺量超过4 %时迅速降低;改性后的PE⁃HD防水板热老化性能受漆渣影响不大;硅烷偶联剂的加入对改善改性后PE⁃HD防水板的断裂伸长率更有利。

Abstract:

A paint residue modified high⁃density polyethylene waterproof board was prepared using high⁃density polyethylene (PE⁃HD) as a matrix resin, solid waste paint residue as a filling modifier, and silane coupling agent (KH⁃560) as an interface modifier. The effects of paint residue content and silane coupling agent dosage on the impermeability, mechanical properties, and thermal aging resistance of the composite material were studied. The experimental results indicated that the elongation at break of the modified PE⁃HD waterproof board decreased significantly with increasing paint residue content, and its tensile strength and contact angle exhibited an initial gradual increase at paint residue levels ≤ 4 wt%, followed by a sharp decline at higher concentrations. The thermal aging resistance of the modified PE⁃HD waterproof board remained largely unaffected by paint residue content. The addition of KH⁃560 improved fracture elongation, demonstrating its effectiveness in enhancing interfacial bonding between the PE⁃HD matrix and paint residue filler. This work highlights the potential of repurposing industrial paint residue into functional additives for polymer composites, offering a sustainable solution for high⁃performance waterproofing materials.
