摘要
为改善复合发泡水泥板性能,克服其易粉化、强度低和吸水高的缺陷,从提高复合发泡水泥板的强度、降低其吸水率进行实验研究。结果表明,掺加憎水剂、苯丙乳液和降低水料比,能大幅度降低复合发泡水泥板的吸水率,提高其强度和表面硬度,克服了复合发泡水泥板易粉化、强度低和吸水高的缺陷。
In order to improve the performance of composite foam cement panels and overcome the defect of easy powder, low strength and high water absorption, experimental research was conducted from the aspect of improving strength and reducing water absorption of composite foam cement panels. Experimental results show that adding hydrophobic agent,styrene-acrylic emulsion and reducing the ratio of water can significantly reduce water absorption and improve its strength and surface hardness of the eompos- ite foam cement panels,and overcome the defect of easy powder, low strength and high Water absorption.
