Abstract

The invention discloses a two-component epoxy asphalt emulsion material and a preparation method thereof and belongs to the field of road and bridge engineering construction and maintenance materials. The two-component epoxy asphalt emulsion material comprises a part A and a part B, wherein the part A is prepared from asphalt, water, an emulsifier, an epoxy resin emulsion and an assistant; and the part B is a curing agent emulsion. The material becomes a thermosetting epoxy asphalt material through room-temperature curing reaction. The material has the advantages of a common emulsified asphalt material which is energy-saving, environment-friendly and simple in construction technology and adopts artificial and mechanized construction according to circumstances, and also has high-temperature stability, low-temperature crack resistance and super-high adhesive property of the thermosetting epoxy asphalt. The two-component epoxy asphalt emulsion material is wide in application, such as waterproof materials of buildings, waterproof adhesive materials for road and bridge engineering, preventive maintenance materials for asphalt pavements and a cold-mix asphalt mixture.

Description

technical field [0001] The invention belongs to the field of road and bridge engineering construction and maintenance materials, and in particular relates to a two-component epoxy asphalt emulsion material and a preparation method thereof. Background technique [0002] As a new road and bridge material, epoxy asphalt has been widely used in large-scale steel bridge deck pavement and bridge waterproof bonding layer. Its excellent properties such as super high and low temperature stability, super strong adhesion and fatigue resistance have been unanimously recognized in the industry. However, due to its complex construction process and high requirements, it seriously affects the further application of its excellent performance. [0003] Emulsified asphalt is also a commonly used road engineering material. It is widely used because of its advantages of energy saving, environmental protection, and convenient construction. However, the current emulsified asphalt or modified emu...
