Abstract

The invention relates to a water-based foam stabilizer, a preparation method of the foam stabilizer and a water-based foam system with the ultrahigh stability. The water-based foam stabilizer is prepared by dissolving a water-soluble high molecular surfactant A in water to form a transparent solution with the mass concentration being 0.1wt% to 1wt%. The invention further provides the preparation method and an application of the water-based foam stabilizer. The surfactant A can be adsorbed in a gas-liquid interface to stabilize foams, the coverage degree of the gas-liquid interface is high, a formed foam liquid membrane is high in liquid holding capacity, the foams are high in stability and are used in the water-based foam system taking nitrogen, carbon dioxide, oxygen, air, flue gas, decarbonized flue gas and the like as gas phases, and the excellent foam stability can be kept even if the carbon dioxide is adopted as foaming gas or under the severe conditions that raw oil exists and the like.

Description

technical field [0001] The invention relates to a water-based foam stabilizer, a preparation method and a water-based foam system with super high stability, and belongs to the technical fields of oilfield chemistry, daily chemistry, mineral processing and the like. Background of the invention [0002] Foam is a polydisperse system of a mixture of gas and liquid, where the liquid is the continuous phase and the gas is the dispersed phase. Water-based foam is widely used in our daily life, such as shampoo, toothpaste, facial cleanser, shower gel and other daily chemical products, as well as in food and beverages such as beer, coffee, and ice cream. The presence of foam enhances the quality of the product, improving the mouthfeel, skin feel or aesthetics of the product. Foam is also used for fire suppression, which creates a blanket effect that reduces the production of combustible gases, helps to trap oxygen, and cools fuel surfaces. [0003] In the industrial field, the dif...
