Embodiment 1

[0038] A kind of water-emulsion type epoxy asphalt paint, comprises the component of following parts by weight:

[0039]

[0040] B component: 593 curing agent 25

[0041] The preparation method is as follows:

[0042] 1) Heating the asphalt to 130°C;

[0043] 2) Add petroleum resin to the heated asphalt in step (1), stir for 1 hour until fully dissolved to form modified asphalt, then cool down to 130°C for later use;

[0044] 3) warming up the water to 55°C;

[0045] 4) Add cationic emulsifier, auxiliary agent, modified latex, and epoxy resin to the heated water in step (3), and stir for 1 hour until a soap liquid with a uniform dissolved state is formed;

[0046] 5) Mix the cooled modified asphalt with the soap solution, carry out shearing and emulsification through a colloid mill according to a ratio of 5:5, cool down to room temperature, and obtain the epoxy emulsified asphalt A component;

[0047] 6) Mix component A and component B according to the mass ratio of 4:...

Embodiment 2

[0049] A kind of water-emulsion type epoxy asphalt paint, comprises the component of following parts by weight:

[0050]

[0051] B component: 593 curing agent 20

[0052] Preparation method is consistent with embodiment 1, only there is following difference:

[0053] In the step (5) of Example 2, the ratio of the modified asphalt to the soap solution is 5:4, and the ratio of the A component to the B component in the step (6) is 5:1.

Abstract

The invention belongs to the field of waterproof coatings and relates to an aqueous emulsion type epoxy asphalt coating and a preparation method of the aqueous emulsion type epoxy asphalt coating. Theaqueous emulsion type epoxy asphalt coating comprises a component A and a component B, the component A comprises 40-55 parts by weight of petroleum asphalt, 0.5-2 parts by weight of a cationic emulsifier, 2-8 parts by weight of petroleum resin, 0.5-2.5 parts by weight of an additive, 5-10 parts by weight of modified latex, 8-12 parts by weight of epoxy resin, and 15-40 parts by weight of water; and the component B comprises a curing agent emulsion, and the mass ratio of the component A to the component B is (4-10):1. The aqueous emulsion type epoxy asphalt coating combines the advantages of emulsified asphalt and epoxy asphalt, has the advantages of high bonding strength, high compatibility with an asphalt roll, environment protection and the like, and is matched with a vertical face of aself-adhesive bituminous waterproof sheet material in the construction, and a composite waterproof layer formed after the construction is excellent in high-temperature and low-temperature weather fastness.

Description

technical field [0001] The invention belongs to the field of waterproof coatings, and more specifically relates to a water-emulsion type epoxy asphalt coating and a preparation method thereof. Background technique [0002] Water-emulsion asphalt coating is an environmentally friendly asphalt-based waterproof coating commonly used in the construction waterproofing industry. It is widely used in waterproofing parts such as roofs, basements, tunnels, road and bridge culverts, garage roofs, and engineering foundations. Its advantages are: construction at room temperature without hot melting, energy saving, simple and convenient construction process, film formation process is completed by water volatilization and emulsion particle fusion, no organic solvent escapes during construction, less environmental pollution, relatively low engineering cost, waterproof Excellent performance etc. [0003] Epoxy asphalt coating is a thermosetting blend composed of epoxy resin, asphaltene cro...
