海泡石提纯改性及在内墙涂覆材料中的应用研究
|
摘要
针对湘潭海泡石原矿进行了提纯和改性处理,去除海泡石内部的石英、方解石等脉石矿物,以疏通其孔道结构,比表面积提升至156.9 m2/g,大幅增强吸附性能。利用改性海泡石制备内墙涂覆材料将显著提高涂料涂层对室内装修建材释放的甲醛等有害气体分子的吸附和固化效果和对室内空气环境湿度的调节性能,充分发挥海泡石涂料产品的功能性。研究了海泡石提纯改性工艺及其在内墙涂覆材料中的应用,验证了涂料样品对甲醛的吸附性,拓展了海泡石高附加值材料化应用的范畴。
Purification and modification of Xiangtan sepiolite raw ore were carried out to remove gangue minerals such as quartz and calcite in sepiolite to dredge the pore structure. The specific surface area was increased to 156.9 m2/g, which greatly enhanced its adsorption performance. The use of modified sepiolite in preparation of interior wall coating materials will significantly improve adsorption performance and curing effect of surface coating on formaldehyde and other harmful gas molecules, which released from home decoration materials. In the meantime, regulation performance of it on indoor air environment humidity will be enhanced. Product functionality of sepiolite paint was brought into full play. The purification technology of sepiolite and its application in interior wall coating were studied. Formaldehyde adsorption of the coating sample were verified, and application category of sepiolite materials with high value was expanded.
