PE basalt fiber composite modified asphalt mixture and preparation method thereof
The invention belongs to the technical field of basalt fibers, and particularly relates to a PE basalt fiber composite modified asphalt mixture and a preparation method thereof. The preparation method of the PE basalt fiber composite modified asphalt mixture comprises the following steps: preparing a PE basalt fiber particle composite material: immersing basalt fibers into a complexing agent, adding a granulating agent, and carrying out a hydrothermal reaction to obtain the PE basalt fiber particle composite material, and preparing the PE basalt fiber composite modified asphalt mixture: mixing the obtained PE basalt fiber particle composite material with an asphalt mixture to obtain the PE basalt fiber composite modified asphalt mixture. The method comprises the following steps: modifying asphalt by adopting polyethylene, preparing PE basalt fiber particles by taking polyethylene (PE) and basalt fibers as base materials under the action of a granulating agent, mixing the PE basalt fiber particles with mineral aggregates at 170-180 DEG C, uniformly melting the polyethylene, mixing the polyethylene with the asphalt, and permeating a polyethylene film into the asphalt, so that the performance of the asphalt of the aggregate is improved; and the polyethylene is rubbed by the aggregate and then is coated on the surface of the aggregate so as to modify the asphalt.
本发明属于玄武岩纤维技术领域，具体涉及一种PE玄武岩纤维复合改性沥青混合料及制备方法。该PE玄武岩纤维复合改性沥青混合料的制备方法，包括以下步骤：制备PE玄武岩纤维颗粒复合材料：将玄武岩纤维浸入络合剂中后，加入造粒剂，经水热反应即得；制备PE玄武岩纤维复合改性沥青混合料：将得到的PE玄武岩纤维颗粒复合材料与沥青混合料拌和后即得。本发明的采用聚乙烯对沥青进行改性，在造粒剂的作用下，以聚乙烯（PE）和玄武岩纤维为基材制备PE玄武岩纤维颗粒，PE玄武岩纤维颗粒在170～180℃下与矿料进行拌和，聚乙烯均匀融化，在与沥青拌和，聚乙烯薄膜渗透到沥青中，改善集料件沥青的性能，聚乙烯经集料摩擦后在集料表面裹附以对沥青进行改性。
