Asphalt-based interface agent and preparation method thereof

The invention relates to an asphalt-based interface agent and a preparation method thereof. The asphalt-based interface agent comprises the following raw materials in parts by mass: 320-450 parts of emulsion; 0.5-1 part of a mildew preventive; 0.8-1.2 parts of a bactericide; 0.2 to 1 part of a thickening agent; 550 to 650 parts of deionized water; 20 to 30 parts of graphite oxide; 1.2 to 1.8 parts of a main defoaming agent; and 50-70 parts of an emulsified asphalt extract. The emulsion and the emulsified asphalt extract are adopted as resin cross-linking substances, so that a good cross-linking effect can be achieved, a certain permeation type is achieved, the durable connecting capacity is achieved, the root rotting phenomenon in the using process is avoided, the structure effect achieved by using the interface agent is greatly improved, and economic loss and potential safety hazards are avoided. 一种沥青基界面剂及其制备方法，包括如下质量份数的原料：乳液：320-450份；防霉剂：0.5-1；杀菌剂：0.8-1.2；增稠剂：0.2-1；去离子水：550-650；氧化石墨：20-30份；主消泡剂：1.2-1.8；乳化沥青
