Rapid pavement repairing material and preparation method thereof
The invention provides a rapid pavement repairing material and a preparation method thereof. The method comprises the following steps: firstly, forming a urea formaldehyde resin layer on the surface of mixed powder by using a urea acetaldehyde prepolymer so as to obtain a preform; mixing the preform with rubber modified asphalt to obtain a premix, and coating the premix with urethane acrylate to obtain a coated premix; and preheating the coated premix, transferring the preheated coated premix into a colloid mill, adding cement mortar, and conducting mixing to obtain the cement mortar. The repairing material prepared by the invention can be used for quickly repairing a pavement, and is good in pavement repairing effect and good in application prospect.
本发明提供了一种路面快速修复材料及其制备方法，该方法先将混合粉利用脲乙醛预聚体在其表面形成脲醛树脂层，得到预制体；再将预制体与橡胶改性沥青混合，得到预混料，接着将预混料利用聚氨酯丙烯酸酯包覆，得到包覆预混料；然后将包覆预混料预加热后转移至胶体磨中，接着加入水泥胶砂，混合即得。本发明所制备的修复材料可是实现路面快速修复，路面修复效果好，应用前景良好。
