土遗址加固的非水分散体材料渗透性能研究

Study on the Infiltration Performance of Acrylic Non-aqueous Dispersion for Reinforcement of Earthen Ruins

通过化学材料加固渗透土遗址是保护土遗址文物较为有效的手段之一.丙烯酸树脂非水分散体材料有加固强度好、渗透性能好等优点,已经运用于实际保护工作中,但仍存在一定的问题.本次实验首先对丙烯酸树脂非水分散体材料的制备材料以及制备工艺进行提升,提高了材料的制备效率以及材料的渗透性能;其次探究不同因素对材料渗透性能的影响,以便在实际应用时针对不同的情况选择合适的材料达到最好的效果;最后,对该材料的加固机理进行探究,发现非水分散体材料主要是成膜后起粘结作用加固土体,为后续材料的去除提供依据.

Reinforcement earth ruins by chemical materials is one of the more effective means to protect the artifacts of earth ruins.Acrylic non-aqueous dispersion has the advantages of good reinforcement strength and good infiltration performance.It has been used in the actual protection work,but there are still some problems.In the present experiment,the raw material and preparation process of Acrylic non-aqueous dispersion were firstly enhanced to improve the material preparation efficiency and material penetration properties.Secondly,to explore the influence of different factors on the permeability of the material,so that the best results can be achieved by choosing the right material for different situations in practical applications.Finally,the reinforcement mechanism of the material was investigated,and it was found that the acrylic non-aqueous dispersion mainly formed a film and then acted as a bond to reinforce the soil,providing a basis for the subsequent removal of the material.
