[0028] Meanwhile, the present invention provides a method for preparing water-based epoxy-modified emulsified asphalt, the steps of which include: mixing the raw materials of the above-mentioned water-based epoxy-modified emulsified asphalt to obtain water-based epoxy-modified emulsified asphalt.

[0029] In some embodiments, the steps include: S1, stirring the water-based epoxy resin at room temperature for 3-5 minutes, adding a curing agent, and stirring for 5-10 minutes; S2, adding a dispersant and stirring for 5-10 minutes; S3, adding butyl Stir benzene latex and water-based acrylic resin for 5-10 minutes; S4, add emulsified asphalt, stir and mix to obtain water-based epoxy-modified emulsified asphalt. Generally, the order of adding the above-mentioned other substances can be adjusted except that the emulsified asphalt is added last.

[0030] More specifically: S1, stir the water-based epoxy resin at room temperature for 3-5 minutes, add an appropriate amount of curing agen...

Embodiment 1

[0035] 20g waterborne epoxy resin HTW608 (solid content is 60%, epoxy equivalent is 200) was stirred at room temperature for 4 minutes, added 0.8g dicyandiamide, 0.08gDMP-30, stirred for 8 minutes; then added 0.4g lignosulfonic acid Sodium, stir for 8 minutes; then add 2g of SBR latex F0602 (Shenzhen Yoshida Chemical Co., Ltd.) and 5g of water-based acrylic resin CQ-3958 (Anhui Legend New Material Co., Ltd.), and stir for 8 minutes; finally add 73g of anionic emulsified asphalt slowly, while adding While stirring, add all the mixture and then stir for 30 minutes to get the water-based epoxy modified emulsified asphalt sample S1.

Embodiment 2

[0037]Stir 40g of water-based epoxy resin F0704 (Shenzhen Yoshida Chemical, 50% solid content, epoxy equivalent 220) at room temperature for 4 minutes, add 1.2g of polyamine curing agent, 0.1g of DMP-30, and stir for 8 minutes; then add 0.5g Sodium lignosulfonate, stirred for 8 minutes; then added 5gSBR latex F0603 (Jining Huakai Resin Co., Ltd.) and 3g water-based acrylic resin AU-1006 (Guangdong Ertu Network Technology Development Co., Ltd.), stirred for 8 minutes; finally 52g anion Slowly add the emulsified asphalt, stir while adding, and stir for 30 minutes after adding all the emulsified asphalt to get the water-based epoxy modified emulsified asphalt sample S2.

Abstract

The invention relates to the technical field of road materials, and particularly discloses water-based epoxy modified emulsified asphalt and a preparation method thereof. The water-based epoxy modified emulsified asphalt is prepared from the following raw materials: emulsified asphalt, water-based epoxy resin, styrene-butadiene latex, water-based acrylic resin and a dispersing agent. Relatively strong interaction among the raw materials is utilized, for example, the styrene-butadiene latex namely SBR latex and the water-based acrylic resin are capable of adjusting the brittleness of the epoxy resin in the raw material composition, so that the obtained water-based epoxy modified emulsified asphalt has certain flexibility; due to the dispersing agent, the water-based epoxy resin and the emulsified asphalt can have good compatibility, so that the water-based epoxy modified emulsified asphalt disclosed by the invention can be hermetically stored for over a month at a room temperature; a layer of flexible membrane is formed through preliminary solidification; the water-based epoxy modified emulsified asphalt has relatively high strength and is not adhered to a wheel; and a bonding layer with higher strength is formed during upper asphalt pavement construction.

Description

technical field [0001] The invention relates to the technical field of road materials, in particular to a water-based epoxy-modified emulsified asphalt and a preparation method thereof. Background technique [0002] Emulsified asphalt is a kind of road building material with low viscosity and good fluidity at room temperature, which can be used at room temperature and can be used with Compared with traditional asphalt, emulsified asphalt has many advantages such as non-toxic, odorless, non-flammable, simple production process, convenient for normal temperature construction, energy saving and emission reduction, and has been widely used in road construction . [0003] Especially the role of emulsified asphalt is particularly important in the paving of permeable course, sticky course and waterproof course, and it has become an irreplaceable asphalt material on the slurry seal course and stone chip overlay. At present, the commonly used sticky layer oil is ordinary emulsified...
