Abstract

The invention discloses a nonionic / cationic composite asphalt emulsifier, OP-10 is reacted with epichlorohydrin to obtain a nonionic intermediate, the nonionic intermediate is reacted with alkylamine, and by chemical reaction, the nonionic surfactant is connected with the alkyl amine for synthesis and preparation of the nonionic / cationic composite asphalt emulsifier. The nonionic / cationic composite asphalt emulsifier is a slow cracking type asphalt emulsifier, and has good emulsifying properties and storage stability on different sources of asphalt and under different pH, and asphalt emulsion performance can reach technical requirements of emulsified asphalt used in roads in technical specification JTG F40-2004 for construction of highway asphalt pavements.

Description

technical field [0001] The invention relates to the synthesis of organic chemical products and their practical application in the field of asphalt road pouring, belonging to the fields of fine chemicals and building materials. Background technique [0002] Asphalt has the characteristics of water and moisture resistance, toughness, wear resistance, etc., and is widely used in the field of road construction. At room temperature, asphalt has poor fluidity and high viscosity, so it cannot be crushed to mix it evenly with aggregate. Traditional asphalt and aggregate mixing methods include solvent method and high-temperature melting method. The solvent method consumes a large amount of organic solvents, and the high-temperature melting method consumes a lot of energy. Both methods pollute the air. The emulsified asphalt technology solves this problem better. question. Environmental decontamination, improve construction conditions. When traditional hot asphalt is heated, a larg...
