Embodiment 1

[0057] The preparation method and application, in specific implementation, include the following steps:

[0058] (1) Weigh by mass, mix and stir 45 parts of deionized water, 2.5 parts of cetyltrimethylammonium bromide cationic emulsifier and 4 parts of chlorine salt additive, slowly add hydrochloric acid, adjust the pH value of the solution to 2.2, and then heated to 60°C to prepare soap liquid;

[0059] (2) Heat 55 parts of 70# base asphalt to 180°C, shear with 2.0 parts of styrene-butadiene-styrene block copolymer at high speed for 1 hour, and develop at 170°C for 1 hour to prepare SBS modified Sexual asphalt. Then stir and mix with 45 parts of soap liquid, and slowly pour into the colloid mill. The colloid mill was preheated to 120°C, and the emulsion was left to stand in the heat exchanger for 1 hour to prepare the SBS modified asphalt emulsion;

Embodiment 2

[0069] The preparation method and application, in specific implementation, include the following steps:

[0070] (1) Weigh by mass, mix and stir 37 parts of deionized water, 2.5 parts of cetylpyridinium bromide cationic emulsifier and 2.5 parts of chloride salt additive, slowly add hydrochloric acid, adjust the pH value of the solution to 2.1, Then heated to 65°C to prepare soap liquid;

[0071] (2) Heat 55 parts of 70# base asphalt to 170°C, shear with 3 parts of styrene-butadiene-styrene block copolymer at high speed for 1 hour, and develop at 160°C for 1.5 hours to prepare SBS modified asphalt. Then stir and mix with 38 parts of soap liquid, and slowly pour into the colloid mill. The colloid mill was preheated to 110°C, and the emulsion was left to stand in the heat exchanger for 2 hours to prepare SBS modified emulsified asphalt;

[0072] (3) Weigh in parts by mass, add 95 parts of 2-methyl methacrylate into a 250ml three-necked flask, and conduct a constant temperature...

Abstract

The invention provides a formula, a preparation method and application of a self-crosslinking fog sealing material based on cationic water-based acrylic acid, and belongs to the technical field of pavement engineering pre-maintenance. Acrylic acid is used as a self-crosslinking material, and the compatibility of acrylic acid and an emulsified asphalt system can be improved after the acrylic acid is subjected to water-based treatment and cationic treatment, so that the fog sealing material is prevented from being demulsified in advance and losing efficacy, and application for improvement treatment of SBS modified asphalt emulsion can be realized, the fog sealing layer material using the self-crosslinking characteristic has excellent high-temperature performance and mechanical strength, and the problem of early failure caused by early stripping of the fog sealing layer is avoided; the adhesion of a fog sealing layer and the pavement is increased, the effective age limit of pavement maintenance treatment is prolonged, and the utilization value of facilitating maintenance management and saving the maintenance cost is achieved.

Description

technical field [0001] The invention belongs to the technical field of pavement engineering pre-maintenance. Background technique [0002] Fog seal is one of the common preventive maintenance measures for pavement. When the asphalt pavement has been in normal service for several years, slight low-temperature cracking, fatigue cracking, and loss of fine aggregates will appear on the surface, which will greatly increase the water permeability of the pavement. . Ambient water seeps into the asphalt mix through cracks or fine aggregate losses, further accelerating water damage to the pavement. If timely pre-maintenance treatment is not carried out during this period, it will lead to more serious road surface damage such as network cracks and potholes. After spraying the mist seal material, with the fluidity of the material, the mist seal layer can penetrate into the cracks, thereby filling the tiny cracks and gaps on the road surface and preventing the water from seeping down ...
