Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with specific embodiments.

[0016] Present embodiment is used for graphene inorganic nanometer wall coating, and this formula comprises the material of following parts by weight:

[0017]

[0018] Graphene has a stable solvophilic group, which greatly improves the dispersion and stability of graphene in the dispersion medium, so that graphene can exist uniformly and stably in the coating for a long time. The two-dimensional lamellar structure of graphene is uniformly dispersed in the graphene-modified inorganic anti-corrosion coating, complements the anti-corrosion filler in the coating, or overlaps each other, or stacks each other, and fills in the inorganic skeleton constructed by the inorganic adhesive. Form a dense shielding layer to inhibit the entry of corrosive factors such as oxygen, chloride ions, and water molecules, so that the graphene-modified inorganic anti-corrosion coating...

Abstract

The invention relates to a graphene inorganic nano wall coating in the field of glue. The formula comprises the following substances in parts by weight: 20-50 parts of water, 0.5-5 parts of graphene, 3-5 parts of anticorrosive filler, 0.2-0.6 part of an antioxidant, 0.5-1.3 parts of a passivating agent, 2-6 parts of a dispersing agent, 10-60 parts of a phosphate adhesive, 5-20 parts of silicon carbide, 3-9 parts of an anti-settling agent, 20-30 parts of olefine acid, 2-5 parts of a solvent, 5-10 parts of nano titanium dioxide, 10-35 parts of a film-forming agent and 0.5-2 parts of a coloring agent. The dispersity and stability of the graphene in a dispersion medium are greatly improved by the coating, so that the graphene can uniformly and stably exist in the coating for a long time. The graphene has a two-dimensional lamellar structure, is uniformly dispersed in the graphene modified inorganic anticorrosive coating and is stacked with the anticorrosive filler in the coating, so that the graphene modified inorganic anticorrosive coating has good shielding and anticorrosive properties and excellent solar reflectivity, the adhesive force of a coating film to a wall body is improved, and the coating is not easy to separate.

Description

technical field [0001] The invention relates to the field of wall coatings, in particular to graphene inorganic nano wall coatings. Background technique [0002] Among building heat insulation materials, heat insulation coating has attracted people's attention because of its advantages such as simple construction, convenient operation, and good heat insulation effect. Buildings, granaries, oil storage tanks, temporary workshops, industrial equipment, etc. are exposed to sunlight for a long time, and their outer surface temperature rises under the sunlight. Especially in summer, due to the increase of outer surface temperature, there will be a large number of The heat is transmitted into the room, and the graphene inorganic nano wall coating is a kind of coating that prevents heat conduction through the high thermal resistance of the coating itself, which belongs to the thick film coating. After the coating is formed into a film, the coating film is full of pores, and the de...
