摘要：

为了探究复合纳米颗粒对环氧丙烯酸酯（EA）涂层阻燃性能的影响，以十六烷基三甲基溴化铵（CTAB）和正硅酸乙酯（TEOS）为原料合成了介孔二氧化硅纳米颗粒，以ZnCl₂和SnCl₄·5H₂O为原料合成了锡酸锌（Zn₂SnO₄）纳米颗粒，将它们复合制成了介孔二氧化硅/锡酸锌复合纳米颗粒（SiO₂/Zn₂SnO₄），并用X射线粉末衍射仪（XRD）、透射电镜（TEM）对其表征。将所制的纳米颗粒（介孔SiO₂、Zn₂SnO₄、SiO₂/Zn₂SnO₄）与丙烯酸、丙烯酰胺、EA复合，经UV光固化制备出3种涂层（SiO₂/EA、Zn₂SnO₄/EA、SiO₂/Zn₂SnO₄/EA），通过紫外-可见光谱仪、差示扫描量热仪（DSC）及氧指数测定仪等对涂层的透光率、热稳定性、阻燃性能进行测试。结果表明：SiO₂/Zn₂SnO₄/EA涂层的综合性能较佳，当SiO₂/Zn₂SnO₄质量分数为4.85%时，该涂层的热稳定性及阻燃性能最佳，其极限氧指数、燃烧级别、残炭率（500℃下马弗炉煅烧）和硬度分别为31、V-0、17.32 % 及6H。

Abstract:

To explore the effect of composite nanoparticles on the flame retardancy of epoxy acrylate (EA) coating, mesoporous silica nanoparticle was synthesized by using cetyltrimethylammonium bromide (CTAB) and tetraethoxysilane (TEOS) as raw materials, and zinc stannate nanoparticle was synthesized based on ZnCl₂ and SnCl₄·5H₂O as raw materials. Then mesoporous silica/zinc stannate nanoparticle complex was prepared by compounding them, and the above nanoparticles were characterized by X-ray powder diffractometer (XRD) and transmission electron microscope(TEM). Three kinds of composite coatings(SiO₂/EA, Zn₂SnO₄/EA, SiO₂/Zn₂SnO₄/EA) were prepared by UV curing method through mixing the above prepared nanoparticles（mesoporous SiO₂, Zn₂SnO₄， SiO₂/Zn₂SnO₄）， acrylic acid, acrylamide with EA, and the transmittance, thermal stability and flame retardancy of the coating were measured by UV-vis spectrometer, differential scanning calorimeter(DSC) and oxygen index tester. The results showed that the comprehensive properties of SiO₂/Zn₂SnO₄/EA coatings were superior. When the mass percent content of SiO₂/Zn₂SnO₄ was 4.85%, the thermal stability and flame retardancy of the coating are the best. The coating’s limiting oxygen index, combustion grade, carbon residue rate (calcined in muffle furnace at 500℃) and hardness were 31，V-0，17.32% and 6H, respectively.
