The invention belongs to the technical field of building material preparation, and particularly relates to a preparation method of high-strength waterproof foam cement. The method comprises the steps:firstly, crushing, mixing and drying ricinus communis and cotton; mixing a modified adhesive, cement and other assistants; after mixing, mixing with water, pouring the mixture into a mold, curing anddemolding to obtain the high-strength waterproof foaming cement. The ricinus communis and the cotton are subjected to alkali liquor high-temperature reaction, molecular chains of plant fibers are broken through the reaction to generate fiber components with short chain lengths, the bonding degree among the components is improved, the structural strength and the compactness of the foamed cement are enhanced, the waterproof performance is improved, and the water absorption rate is reduced; carboxyl groups are grafted in the fibers; through complexing adsorption, the structural strength of the foamed cement is improved, meanwhile, elementary substance aluminum particles are generated through copper powder replacement, the waterproof performance of the foamed cement is improved, meanwhile, the elementary substance aluminum particles are dispersed in the foamed cement and react to generate an aluminum oxide film, other components are prevented from making contact with air, the flame retardant property is improved, and wide application prospects are achieved.
本发明属于建材制备技术领域，具体涉及一种高强度防水型发泡水泥的制备方法。本发明首先将蓖麻与棉花粉碎混合干燥，将改性粘性剂、水泥等助剂混合，混合后与水混合投入模具中固化脱模即得高强度防水型发泡水泥，本发明将蓖麻与棉花经过碱液高温反应，经过反应使植物纤维分子链断裂生成链长较短的纤维成分，提高各成分之间的粘结程度，增强发泡水泥的结构强度和致密性能，以提高防水性能，降低吸水率；将纤维中接枝羧基基团，通过络合吸附，提高发泡水泥的结构强度，同时利用铜粉置换生成铝单质颗粒，提高发泡水泥的防水性能，同时铝单质颗粒分散于发泡水泥中，反应生成氧化铝薄膜避免其它成分与空气接触，提高阻燃性能，具有广阔的应用前景。
