电气石/环氧树脂复合卷材制备及负氧离子释放性能OA

Composite materials with the capability of releasing negative oxygen ions have held broad application prospects in the air purification field.With the steady release high-performance of negative oxygen ions tourmaline/epoxy resin composite coil is constructed,which applies tourmaline superfine powder as a functional filler onto bisphenol-A epoxy resin as the matrix through the coating process.The results demonstrate that when the tourmaline superfine powder addition content was between 10％and 30％,the negative oxygen ions concentration released by the composite material exceeded the Grade Ⅰ air standard(＞1200 ions/cm3).Notably,under a 30％addition condition of tourmaline superfine powder,the negative oxygen ions release reached 4315 ions/cm3,with an abrasion loss of 0.0234 g and a Shore hardness of 72.4 HD.Moreover,the composite coiled material exhibited excellent environmental adaptability and functional stability,maintaining a negative oxygen ion release level exceeding 1200 ions/cm3 under various environmental factors,including temperature variations,humidity levels,and airflow disturbances.
