Problems solved by technology

[0009] The invention relates to a water-based epoxy floor paint composition. The water-based epoxy floor paint according to the invention belongs to a water-based system, and the whole system does not contain VOC, and is a green and environmentally friendly water-based epoxy floor paint; further , the water-based epoxy floor paint of the present invention is an acrylic resin hybrid modified water-based epoxy floor paint, which overcomes the shortcomings of traditional water-based epoxy floor paints such as poor weather resistance and yellowing resistance, It has good anti-ultraviolet performance and excellent weather resistance, and can be used outdoors completely; furthermore, the water-based epoxy floor paint of the present invention can make the product solidify within 24 hours by adding appropriate hardening filler types and curing agents. Pencil hardness ≥1H has higher mechanical properties than traditional water-based epoxy resins; in addition, the water-based epoxy floor paint of the present invention has a shorter surface-drying / hard-drying time by adding an appropriate epoxy resin curing accelerator Time, shorter hardening time, has better construction performance than traditional water-based epoxy; Finally, the water-based epoxy floor paint of the present invention passes the proportioning of optimal hardening filler / toughening filler and thickening filler, By adding a toughening agent compatible with the floor paint components, the toughness of the paint film can be further improved without reducing the hardness of the paint film, and it has good scratch resistance after curing for 1 day, which can reach Balance of film hardness and toughness

Embodiment 1

[0047] The preparation steps of A component in the present embodiment 1 are as follows:

[0048] (1) Preparation of water-based epoxy resin: first, turn on the disperser at low speed, put emulsifier and liquid epoxy resin E-51 into the disperser, set the stirring speed to 1000-2000rpm after putting in, under high-speed shear condition First mix the emulsifier and liquid epoxy resin for 10-50 minutes until uniform, then slowly add deionized water to the system under the shear condition of 500-2500rpm until the epoxy equivalent of the prepared water-based epoxy resin is 400 Stop adding water when the water content gradually increases, and the whole system gradually changes from water-in-oil to oil-in-water, and finally forms a uniform and stable water-based epoxy emulsion system.

[0049] (2) Preparation of acrylic-based resin hybrid modified water-based epoxy resin: start the disperser at low speed, first put pure acrylic emulsion BY-510TS into the disperser, set the stirring s...

Embodiment 2

[0055] The A-component acrylic-based resin hybrid modified water-based epoxy resin in this example is purchased from AEH-2014 of DOW Company, and the preparation steps of the B-component of the acrylic-modified epoxy resin are as follows:

[0056] First, add 40 parts of deionized water to the stirring container, set the speed at 200-500rpm, first add dispersant and defoamer to it, then adjust the stirring speed to 700-1000rpm, stir for 3-10min; then reduce the stirring speed to 200- 500rpm, add epoxy resin curing agent and thickener respectively, adjust the stirring speed to 800-1200rpm, stir for 10-20min; then reduce the stirring speed to 200-500rpm, respectively add 4000 mesh whitening filler, 1250 mesh hardening filler, 800-mesh toughening filler, 800-mesh incremental filler, 800-mesh thickening filler accelerator, toughening agent and color paste, etc. After feeding, adjust the stirring speed to 800-1200rpm, stir for 15-20min to obtain component B, each group See Table 1 f...

Embodiment 3

[0060] The preparation steps of A component in the present embodiment 3 are as follows:

[0061] (1), the preparation of water-based epoxy resin: first open the disperser at a low speed, drop into emulsifier, liquid epoxy resin E-51 and ethylene glycol diglycidyl ether in the disperser, wherein ethylene glycol diglycidyl ether The dosage is 5% of E-51. After the input is completed, set the stirring speed to 1000-2000rpm. Under the condition of high-speed shearing, first mix the emulsifier and liquid epoxy resin for 10-50min until uniform, and then mix the emulsifier and liquid epoxy resin at 500-2500rpm Slowly add deionized water to the system under certain conditions, and stop adding water until the epoxy equivalent of the prepared water-based epoxy resin is 400. As the amount of water gradually increases, the entire system gradually changes from water-in-oil to oil-in-water , and finally form a uniform and stable water-based epoxy emulsion system.

Abstract

The invention discloses a water-based epoxy floor paint composition capable of being used outdoors. The water-based epoxy floor paint composition comprises a component A and a component B, wherein according to the mass proportion, the ratio of A to B is (80-150):100; the component A is acrylic resin hybrid modified water-based epoxy resin; the epoxy equivalent of the acrylic resin hybrid modified water-based epoxy resin is 800 to 1500. The water-based epoxy floor paint provided by the invention belongs to a water-based system, the whole system does not contain VOC, and the water-based epoxy floor paint is environmentally-friendly water-based epoxy floor paint; moreover, hybrid modification is conducted by the acrylic resin, so that the defects that the traditional water-based epoxy floor paint has low weather resistance and does not resist yellowing are overcome, and the water-based epoxy floor paint composition is high in ultraviolet resistance and excellent weather resistance and can be completely used outdoors.
