The invention discloses a preparation method of building rubber powder, which belongs to the technical field of buildings. The graft polymer obtained by the invention contains catechol groups which are easy to oxidize to generate quinonyl groups to form a high-molecular reticular polymer, which is a breathable and hydrophobic aggregate film and can generate a chemical reaction with protected mortar to improve the bonding strength and water resistance of the building rubber powder; the water-resistant rubber powder prepared in the invention is a dispersive rubber powder substance; a small amount of cement is used as a hydraulic binding material; the bonding strength and hardness of the cured rubber powder dispersion liquid are improved; the water resistance of the rubber powder surface is improved; a protein starch mixture contains a small amount of lecithin after being treated, the lecithin can be used as an emulsifier, the surface energy of the lecithin is low, the hydrophobic property is excellent, the lecithin can be combined with protein in the protein starch mixture to form a water-resistant lipoprotein molecular layer to be compatible with petroleum asphalt absorbed and infiltrated in inorganic stone powder, and the water resistance and the initial viscosity of the building rubber powder are improved.
本发明公开了一种建筑胶粉的制备方法,属于建筑技术领域。本发明所得的接枝聚合物含有易氧化产生醌基的邻苯二酚基团,形成高分子网状聚合物,这是一种透气疏水的集合膜,它能与被保护砂浆产生化学反应,提高建筑胶粉粘结强度和耐水性能;本发明中所制备的耐水胶粉是一种分散性胶粉类物质,它以少量水泥作为水硬性粘结材料,提高了胶粉分散液固化后的粘结强度和硬度,提高胶粉表面的耐水性,蛋白淀粉混合物经过处理后含少量卵磷脂,可作为乳化剂,卵磷脂表面能较低,具有优良的憎水性能,并且它能与蛋白淀粉混合物中蛋白质结合成耐水脂蛋白分子层与无机石粉中吸渗的石油沥青相容,提高建筑胶粉的耐水性能和初始粘度。
