可聚合纳米无机氧化物杂化材料在紫外光固化涂料中具有较好的分散性能,与涂料中的单体和预聚物进行光聚合形成有机/无机杂化网络结构的聚合物,从而提高涂料固化膜的热稳定性能、硬度和耐磨性能等,在紫外光固化涂料的制备方面有着广阔的应用前景。目前,该类杂化材料主要采用硅烷偶联剂改性、化学接枝改性和溶胶—凝胶方法制备。本文就可聚合纳米无机氧化物杂化材料的制备和其在紫外光固化涂料中的应用进展进行了概述,并提出了对该类材料进一步开发和工业化应用的建议。
Polymerizable nano inorganic oxide hybrid materials in the UV-curable coatings have better dispersion properties, and coating materials monomer and prepolymer photopolymerization to form organic / inorganic hybrid network structure of the polymer, thereby enhancing the coating The thermal stability of the cured film, hardness and wear resistance, etc., in the preparation of UV-curable coatings has broad application prospects. At present, these hybrid materials are mainly prepared by silane coupling agent modification, chemical grafting modification and sol-gel method. This paper summarizes the preparation of polymerizable nano-inorganic oxide hybrid materials and their application in UV-curable coatings, and puts forward some suggestions for the further development and industrial application of this kind of materials.
