[0022] Embodiment 1 prepares the aqueous amine-epoxy adduct of amine termination

[0023] 1. See Table 1 for the formula

[0024] Table 1

[0025]

[0026] Note: "percentage" refers to the percentage of the total amount added.

[0027] 2. Operation method

[0028]In the reactor equipped with stirring, heating equipment, nitrogen conduit, reflux condenser and thermometer, enter 113 parts of bisphenol A diglycidyl ether and 100 parts of polyethylene glycol 2000 and 161 parts of xylene solvent, heat To the reflux temperature, stir until the material is completely dissolved, and add 2.3 parts of catalyst zinc chloride. At a reaction temperature of 125±5°C, react for 8 hours, lower the temperature to 50-60°C, add 41.2 parts of diethylenetriamine, keep the temperature for 1 hour, and obtain an amine-terminated epoxy adduct; then raise the temperature to 200°C, Distill at 200°C and 724mmHg for 10 minutes to remove the unreacted diethylenetriamine and xylene solvent, then vent ...

Embodiment 2

[0029] Embodiment 2 prepares the component B of two-component waterborne epoxy paint

[0030] 1. See Table 2 for the formula

[0031] Table 2

[0032]

[0033] Note: "percentage" refers to the percentage of the total amount added.

[0034] 2. Operation method

Abstract

The invention relates to a bicomponent water-based epoxy paint for an aluminum alloy material and a composite material. A component 1 and a component 2 all comprise an amino end-capped water-based amino-epoxy addition compound, which uses 5 to 10 percent of alkenyl polyamine, 5 to 12 percent of mono-epoxy compound, 10 to 20 percent of polyether polylol, 15 to 25 percent of bisphenol-A diglycidyl ether, 0 to 5 percent of organic acid, 15 to 20 percent of latent solvent and 25 to 40 percent of deionized water as raw materials to react through a step polymerization in the presence of a catalyst; the component 1 consists of 30 to 50 percent of the amino end-capped water-based epoxy addition compound, 20 to 40 percent of paint, 0 to 15 percent of filling agent, 0.1 to 1 percent of defoaming agent, 0.1 to 1 percent of wetting dispersant, 15 to 30 percent of deionized water and 1 to 15 percent of solvent; and the component 2 consists of 50 to 65 percent of the bisphenol-A diglycidyl ether, 3 to 10 percent of the amino end-capped water-based epoxy addition compound and 25 to 45 percent of the deionized water.

Description

technical field [0001] The invention relates to a two-component waterborne epoxy coating for aluminum alloy materials and composite materials. Background technique [0002] Due to the unique properties of aluminum alloy materials and composite materials, in recent years, their application range is expanding year by year, and their consumption is also increasing. In order to further improve the various resistance and decorative effects of aluminum alloy materials and composite materials, a relatively simple method is to coat the surface with paint. As we all know, aluminum alloy materials oxidize with oxygen in the air under natural conditions to form oxide films. Achieving good adhesion limits the application range of aluminum alloy materials; composite materials are multiphase materials composed of two or more materials, one of which is one or more reinforcements such as glass fibers , carbon fiber, aramid fiber and boron fiber, etc. The other phase is a bonding agent suc...
