摘要:
为减少铝粉在光固化树脂中的沉降，使其适用于光固化增材制造，使用不同表面活性剂对铝粉进行预处理，增强铝粉表面对有机物的亲和性；利用乳液聚合法使单体聚合在铝粉表面形成一层有机物薄膜，研究几种单体对铝粉包覆性能的影响，利用可见光分光光度计、傅里叶红外光谱仪表征其包覆性能。结果表明：使用十二烷基硫酸钠(K12)预处理的铝粉在光固化树脂中分散性最好，透光率为11%，分散1 h后透光率变化不大；使用苯乙烯（St）+丙烯酸丁酯(BA)、丙烯酸(AA)+丙烯酸丁酯(BA)二元聚合包覆的铝粉在树脂中静置1 h,未发现明显沉降；红外光谱图显示,两组配方中的铝粉表面存在单体聚合产物。
Abstract:
In order to reduce the deposition of aluminum in the light-cured resin to make it applicable in manufacturing the light-cured additives, different surfactants were used to pretreat the aluminum powder to enhance its surface af-finity to the organic substances. Emulsion polymerization method was used to polymerize monomers on the surface of aluminum to create an organic thin film. Influence of several monomers on the coating performance of aluminum was studied. Coating properties were characterized by visible spectrophotometer, Fourier infrared spectrometer and SEM. The results show that aluminum with sodium dodecyl sulfate (K12) has the best dispersion in the light-cured resin, and the transmittance is 11% which does not change much after dispersing for 1 h. Aluminum coated with styrene (St) and butyl acrylate (BA), acrylic acid (AA) and butyl acrylate (BA) have no obvious sedimentation in the resin after standing for 1 h. Infrared spectra shows the existence of monomer polymerization products on the surface of aluminum powder in the two formulations.
