LIQUID LIGHTENING AGENT, PREPARATION THEREOF, AND APPLICATION THEREOF

The present application discloses a liquid lightening agent, a preparation thereof, and an application thereof. The liquid lightening agent comprises water, hollow microspheres, and a high molecular polymer, the weight ratio of the water, the hollow microspheres, and the high molecular polymer being (40-60):(26-56):(0.5-2). The lightening agent provided by the present application can reduce density, and is also a lightening material that can be added in liquid form. The liquefied addition of a lightening material is achieved, thereby implementing the flexible preparation of a low-density cement slurry, and providing convenience for the preparation of the low-density cement slurry on site. In addition, the lightening agent provided by the present application can be stored stably for a long time. La présente demande divulgue un agent liquide d'allègement, une préparation de cet agent et son application. L'agent liquide d'allègement comprend de l'eau, des microsphères creuses et un polymère à grande masse molécu
