摘要

为开发兼具优异力学性能与多功能特性的新型皮革涂饰剂，解决传统聚合物涂饰剂性能单一、纳米填料易团聚及功能协同不足等核心问题，构建了二维层状双金属氢氧化物(LDH)与零维氧化锌(ZnO)的复合纳米结构(LDH@ZnO)，并通过机械共混将其引入无皂共聚物乳液(H-P)，制备了LDH@ZnO/H-P纳米复合涂饰剂。研究结果表明，LDH@ZnO复合结构有效促进了纳米组分在基体中的分散与界面结合。与纯H-P膜及单一填料复合膜相比，LDH@ZnO/H-P涂饰膜展现出显著增强的综合性能：其抗张强度提升至9.98 MPa，耐磨性明显改善(平均摩擦系数降至0.09)；基于LDH与ZnO的协同作用，涂饰革样阻燃性能优异(燃烧时间仅15 s)；同时，该复合涂层具备优异的保温性(导热系数0.05 W·m

Abstract

To develop a new leather finishing agent with excellent mechanical properties and multifunctional characteristics

addressing the core issues of traditional polymer coatings-such as single performance

easy aggregation of nanofillers and insufficient functional synergy

this study constructed a composite nanostructure (LDH@ZnO) of two-dimensional layered double metal hydroxides (LDH) and zero-dimensional zinc oxide (ZnO). Through mechanical blending

this structure was incorporated into a soap-free copolymer emulsion (H-P)

resulting in the preparation of an LDH@ZnO/H-P nanocomposite finishing agent. This study demonstrated that the LDH@ZnO composite structure effectively promoted the dispersion and interfacial bonding of nanocomponents in the matrix. Compared to pure H-P films and films with single filler composites

the LDH@ZnO/H-P coated films exhibited significantly enhanced comprehensive performance: tensile strength increased to 9.98 MPa

wear resistance improved markedly (average friction coefficient reduced to 0.09); leveraging the synergy between LDH and ZnO

the finished leather samples demonstrated excellent flame retardancy (burning time of only 15 s); simultaneously

the composite coating exhi

bited superior thermal insulation (thermal conductivity of 0.05 W·m

UV shielding capability

and thermal stability. This work achieved synergistic improvement in multiple properties through a two-dimensional/zero-dimensional nanocomposite strategy

providing an effective approach for designing high-performance

multifunctional leather finishing materials.
