Abstract

The invention discloses a novel tall oil asphalt emulsifier which is composed of, by weight, 20-25 parts of tall oil, 10-12 parts of mixture of halohexadecane and octadecane, 10-12 parts of mixture of epoxy hexadecane and epoxy octadecane, 15-20 parts of polyethylene polyamine, 5-10 parts of epichlorohydrin, 5-10 parts of trimethylamine dodecyl alcohol, 5-8 parts of ethylenediamine and 3-8 parts of auxiliary. The novel tall oil asphalt emulsifier is high in storage stability, excellent in emulsifying performance and high in reusability for various base materials.

Description

technical field [0001] The invention relates to the technical field of emulsifier preparation, in particular to a novel tall oil asphalt emulsifier and a preparation method thereof. Background technique [0002] Asphalt is an indispensable infrastructure material in transportation and construction projects. It is mainly used in the form of hot asphalt, diluted asphalt and emulsified asphalt. Because the hot asphalt process needs to heat the asphalt to maintain a certain fluidity and evenly mix with the base material during the period, it produces a lot of carbon emissions and environmental pollution, and even leads to the aging of the asphalt adhesive. Under the influence of the global energy crisis, the calls for saving energy, saving resources and reducing pollution in road construction projects are getting louder and louder, which has aroused people's great attention. In this situation, after long-term road construction practice, the development and application of cati...
