Abstract

The invention discloses a slow breaking and quick setting cationic asphalt emulsifier, consisting of the following components: fatty acid containing 16-22 carbons, triethylene tetramine, organic solvent, antioxidant, catalyst and nonionic surfactant. In the preparation process of the slow breaking and quick setting cationic asphalt emulsifier, the asphalt emulsifier is prepared by adopting a microwave heating technology, so that the synthesis time is 2.5-3h shorter than the traditional time. When the emulsified asphalt prepared from the slow breaking and quick setting cationic asphalt emulsifier is used for a thin slurry sealing layer, the consumption is 0.8-1.2%; moreover, a pavement can be quickly set, the open traffic time can be shortened to 30-40min, and quick traffic can be realized. The asphalt content of the emulsified asphalt prepared from the slow breaking and quick setting cationic asphalt emulsifier can reach 70%. The whole synthesis process does not pollute the ambient environment.

Description

technical field [0001] The invention relates to the technical field of asphalt emulsifiers, and mainly relates to a slow-cracking and fast-setting cationic asphalt emulsifier and a preparation method thereof. Background technique [0002] At present, most of the asphalt pavements in our country are in the state of overload or overdue service, and the road conditions are poor, which is difficult to meet the needs of the current transportation conditions; in addition, the asphalt pavements of high-grade highways built since the 1980s and 1990s also need frequent maintenance. . Natural or synthetic organic or inorganic materials are added to asphalt or asphalt mixture, and natural or synthetic organic or inorganic materials are melted or dispersed in asphalt to react with asphalt or wrap on the surface of asphalt aggregates, which can improve or enhance the performance of asphalt Pavement performance, that is, emulsified asphalt, emulsified asphalt refers to a suspension obtai...
