preparation example Construction

[0028] The present invention also provides a preparation method of the anti-peeling agent of the present invention, the preparation method comprises aliphatic amine and structural formula R 1 C 2 h 3 The epoxy chloroalkanes of ClO undergo a ring-opening reaction to obtain an intermediate with a structural formula of R 1 C 2 h 3 The overlapping orbitals of the epoxychloroalkanes of ClO are unstable at a specific temperature, and are easily subjected to ring-opening reactions to obtain intermediates under the attack of amines; the intermediates and structural formulas are R 2 -R 3 -R 4 -N reacts with amines to obtain anti-stripping agent. Specifically, the ring-opening reaction and the intermediate and structural formula are R 2 -R 3 -R 4 The reactions of -N amines are carried out in a solvent, and the solvent is distilled off after the reaction. The solvent is at least one selected from ethanol, methanol, toluene, ethyl acetate, cyclohexane or n-hexane. The reaction ...

Embodiment 1

[0038] Add 1 mol of octadecylamine, 2 mol of epichlorohydrin and 0.05 L of ethanol into the flask and heat to 35°C for 4 hours to obtain an intermediate product, add 2 mol of methylamine, heat up to 90°C for 10 hours and then distill off the ethanol to obtain the structural formula Anti-stripping agents as follows.

[0039]

Embodiment 2

[0041] Add 1 mol of octadecylamine, 2.1 mol of epichlorohydrin and 0.05 L of n-octane into the flask and heat to 70°C for 7.5 hours to obtain an intermediate product. Octane, for an anti-stripping agent.

Abstract

The invention relates to the technical field of asphalt additive, and specifically discloses an anti-stripping agent, a preparation method thereof, and a liquid asphalt comprising the same. Accordingto the preparation method, aliphatic amine with a structural formula of RNH2 and epoxy chloro-alkane with a structural formula of R1C2H3ClO carry out ring-opening reactions to obtain an intermediate;and the intermediate reacts with amines with a structural formula of R2-R3-R4-N to obtain the anti-stripping agent. The preparation method has the advantages of mild reaction conditions, simple technology, and cheap raw materials. Liquid asphalt containing the anti-stripping agent can reach 5-grade after a water immersion method.

Description

technical field [0001] The invention relates to the technical field of asphalt additives, in particular to an anti-stripping agent, a preparation method of the anti-stripping agent and liquid asphalt containing the anti-stripping agent. Background technique [0002] As a road material, asphalt is widely used in road construction. With the increase of traffic volume, more and more wear-resistant and anti-slip acidic stones are used, especially in the central and northwestern regions of my country, where alkaline stones are scarce, and acidic stones are mostly used. Acidic stone has the characteristics of hard stone, compactness, and strong wear resistance. The disadvantage is that it has poor adhesion to asphalt, and it is easy to cause peeling of the asphalt film under the action of moisture, resulting in water damage such as grain drop and potholes on the asphalt pavement. [0003] Water damage of asphalt pavement is one of the main diseases affecting the performance of a...
