Application of lower molecular weight Y-type hydrophilic group amphiphilic molecule compound in the aspect of improving viscosity and stability of asphalt emulsion

Abstract

The invention discloses application of a lower molecular weight Y-type hydrophilic group amphiphilic molecule compound in the aspect of improving viscosity and stability of an asphalt emulsion. The structural formula of the compound is shown in the description. The lower molecular weight Y-type hydrophilic group amphiphilic molecule compound is adopted as a stabilizer and a thickener, the compound forms a disperse system with water, asphalt and an emulgator at a certain temperature through grinding of a colloid mill, the Y-type hydrophilic group amphiphilic molecule compound forms microscler worm-like micelles with mineral oil of the asphalt in water, space-grid structures are formed through crosslinking among the worm-like micelles, solid asphaltene suspends in the space-grid structures, the viscosity of the asphalt emulsion is improved, and meanwhile the effect of improving the stability of the asphalt emulsion is achieved. According to the method, storage duration and service life of the asphalt emulsion can be increased from 15 days to 180 days, compared with a current normally applied macromolecule stabilizer, the lower molecular weight Y-type hydrophilic group amphiphilic molecule compound is convenient to produce and operate, and production equipment-colloid mill of the asphalt emulsion cannot be twined and blocked to reduce the production efficiency because polymeric membrane is formed.

Description

technical field [0001] The patent of the present invention relates to a method for increasing the viscosity and stability of asphalt emulsion, in particular to the application of a low molecular weight Y-type hydrophilic group amphiphile compound in improving the viscosity and stability of asphalt emulsion, which belongs to the energy saving and environmental protection of asphalt application field. Background technique [0002] As a by-product of petroleum refining, asphalt is widely used in road construction and maintenance, and waterproof membranes in buildings due to its good waterproof, corrosion resistance, and excellent adhesion to various road materials and building materials such as stone and cement. And waterproof coatings, ships and oil fields, chemical industry and other fields of heavy anti-corrosion. Due to the high freezing point of asphalt, it usually needs to be heated to about 140°C to become a flowing liquid before use. When the asphalt is heated and use...
