| 摘 要： | 为了提高普通针刺滤料的空气过滤效率，在其表面涂覆一层泡沫涂层，进行表面精细化处理。文章对泡沫涂层剂的配方和工艺进行了研究，结果表明：当泡沫涂层剂中PTFE乳液的含量为20％，有机硅改性丙烯酸酯的含量为25％，羟乙基纤维素钠的含量为1．0％，羟丙基甲基纤维素的含量为0．3％，十二烷基硫酸钠的含量为2．0％，焙烘温度为140℃，焙烘时间为5min时，得到的泡沫涂层滤料的透气性能最佳。与普通滤料相比，泡沫涂层滤料的过滤效率要优于前者。

| Abstract: | This article studies the formulation and process of foam coating on a needle-punched air filter material. At 25% polytetrafluoroethylene concentration, the other concentrations were as follows： hydroxyethyl cellulose, 1%; hydroxypropyl methyl cellulose, 0. 3%; sodium dodecyl sulfate, 2%; and organsilicone-modified acrylates, 25%. The curing temperature was 140℃ and the curing time was 300 s. The foam-coated fabrics had the largest air permeability value, which was almost 95 L·m-2 . s-1. Compared with normal filter material and filter material laminated with a membrane, the foam-coated filter has higher filtering accuracy and lower filtering resistance. |
