Single-component polyurethane mortar mixture and preparation method thereof
The invention belongs to the technical field of road engineering, and particularly discloses a single-component polyurethane mortar mixture and a preparation method thereof. The preparation method has the characteristics that the grading, the preparation method, the performance requirements and the like of the single-component polyurethane mortar mixture are clearly explained and stipulated. The grading of the single-component polyurethane mortar mixture and the design of the polyurethane content do not take the volume index as the standard, but are based on the performance index of the single-component polyurethane mortar mixture. According to the preparation of the single-component polyurethane mortar mixture, a reasonable forming process and curing conditions are determined according to the strength forming characteristics and influence factors of the single-component wet-curing polyurethane, so that the polyurethane is completely cured, and the performance of a test piece is not influenced. Compared with the prior art, according to the characteristics of the polyurethane and mortar mixture, the gradation design, the performance requirement and the preparation method of the polyurethane and mortar mixture are revised, so that diseases caused by instability of a mortar layer under the conditions of high temperature and high load in pavement of a mortar-containing pavement structure are reduced.
本发明属于道路工程技术领域，具体公开了一种单组分聚氨酯胶砂混合料及其制备方法。本发明的特点在于对单组分聚氨酯胶砂混合料的级配、制备方法、性能要求等都进行了明确说明与规定。所述单组分聚氨酯胶砂混合料的级配和聚氨酯含量的设计不以体积指标为标准，而基于其性能指标。所述单组分聚氨酯胶砂混合料的制备，应根据单组份湿固型聚氨酯的强度形成特点和影响因素，确定合理的成型工艺和养生条件，确保聚氨酯完全固化，不影响试件性能。与现有技术相比，本发明针对聚氨酯和胶砂混合料的特点，对其级配设计、性能要求和制备方法进行修订，以减少含胶砂路面结构铺装中，在高温和高荷载条件下胶砂层失稳导致的病害。
