[0032] The formula is shown in Table 1.

[0033] Preparation:

[0034] Prepare graphene aqueous solution:

[0035] Select graphene nanosheets with a sheet diameter of 1-3 μm and a thickness of 1-5 nm, add 65wt% water as a dispersion medium in an ultrasonic device, and then add 5wt% isopropanol, 10wt% polyvinylpyrrolidone and 20wt% graphite olefin sheets, ultrasonically disperse for 3 hours, let stand for 24 hours, take the supernatant, put it in a centrifuge, centrifuge at 5000r / min for 30min, and take the supernatant;

[0036] Preparation of graphene-modified waterborne elastic coatings:

[0037] First add accurately weighed water into the pulling tank, and slowly add dispersant, wetting agent, film-forming agent, defoamer, neutralizer, and preservative in sequence at a low speed of 400r / min. Stir for 2 minutes, increase the rotation speed to 700r / min at medium speed, add titanium dioxide and filler in turn, increase the rotation speed to 1000r / min, disperse at high speed ...

Abstract

The invention discloses a graphene modified water-based elastic coating composition. The composition is prepared from the following components in parts by mass: 38 to 43 parts of elastic emulsion, 13 to 18 parts of titanium dioxide, 20 to 25 parts of filler, 0.2 to 0.3 part of wetting agent, 0.5 to 0.6 part of dispersing agent, 0.1 to 0.2 part of neutralizing agent, 0.2 to 0.4 part of defoaming agent, 0.4 to 0.6 part of coalescing agent, 2 to 2.5 parts of graphene aqueous solution, 15 to 30 parts of water and 0.5 to 1 part of thickening agent, wherein the concentration of the graphene in the graphene aqueous solution is 1.2 mg / ml to 1.4 mg / ml. The coating composition disclosed by the invention not only has relatively strong texture, relatively good weather resistance, water resistance, alkali resistance and excellent stain resistance, but also has fireproof and antibacterial functions and the like.

Description

technical field [0001] The application relates to the technical field of coatings, in particular to a graphene-modified water-based elastic coating and a preparation method thereof. Background technique [0002] Exterior wall paint is exposed to the outdoors for a long time, and is affected by sunlight, rain, wind and sand, changes in cold and heat, etc. After a period of time, the appearance of the finish will crack, peel off, powder, change color, and fade. Especially in the northwestern region, the climate is dry, the ultraviolet rays are strong, and the temperature difference between day and night is large, which causes cracks in the walls. Building cracks are the most common problems in today's building construction quality, and they have been plagued by today's construction industry for a long time. The appearance of cracks not only affects the aesthetics of building finishes, but also adversely affects and even endangers the building itself. [0003] In architectural...
