Problems solved by technology

Chinese patent CN107556920A discloses a self-healing antistatic coating, which uses epoxy resin agent and self-healing microcapsules, and adds antistatic powder to obtain a self-healing antistatic coating. On the basis of antistatic effect, it also has Certain self-healing effect, when micro-cracks occur in the coating, the coating is actively repaired, but the coating process prepared by this method is complicated and the cost is high, which cannot meet the needs of most users

Embodiment 1

[0044] According to the formula weight ratio, mix 20.0 parts of water and 0.2 parts of cellulose in a container, stir at a speed of 800r / min until the cellulose is completely dissolved, and form a mixed solution; add 5 parts of ethylene glycol, 0.4 1 part of sodium dodecylbenzenesulfonate, 0.1 part of wetting agent and 0.2 part of defoamer are stirred evenly; add 4.5 parts of carbon nanotubes and 25 parts of composite titanium dioxide, and disperse at a speed of 1500 r / min until the fineness is less than 60 μm; Reduce the rotation speed, add 55.0 parts of water-based acrylic polyaniline, and slowly add 0.8 parts of antistatic ionic liquid after dispersing evenly; finally add 0.2 parts of preservatives, 0.2 parts of antifungal agents, and 0.1 parts of thickeners in sequence, and discharge after dispersing evenly , That is, antistatic interior wall paint.

Embodiment 2

[0046] According to the formula weight ratio, mix 20 parts of water and 0.3 parts of cellulose in a container, stir at a speed of 800r / min until the cellulose is completely dissolved, and form a mixed solution; add 4.5 parts of ethylene glycol, 0.4 parts of 1 part of sodium dodecylbenzene sulfonate, 0.2 part of stearyl alcohol, 0.1 part of wetting agent and 0.2 part of defoamer and stirred evenly; add 6 parts of carbon nanotubes and 20 parts of composite titanium dioxide, and disperse at 1500r / min to The fineness is less than 60μm; reduce the speed, add 50.0 parts of water-based acrylic polyaniline, and slowly add 0.6 parts of antistatic ionic liquid after dispersing evenly; finally add 0.5 parts of preservatives, 0.5 parts of antifungal agents, and 0.3 parts of thickeners in sequence, After uniform dispersion, the material is discharged, and the antistatic interior wall paint is obtained.

Embodiment 3

[0048] According to the formula weight ratio, mix 25 parts of water and 0.4 parts of cellulose in a container, stir at a speed of 800r / min until the cellulose is completely dissolved, and form a mixed solution; add 3.5 parts of ethylene glycol, 0.2 1 part of sodium dodecylbenzene sulfonate, 0.4 part of stearyl alcohol, 0.2 part of wetting agent and 0.3 part of defoamer and stirred evenly; add 5 parts of carbon nanotubes and 10 parts of composite titanium dioxide, and disperse at 1500r / min to The fineness is less than 60μm; reduce the speed, add 45.0 parts of water-based acrylic polyaniline, and slowly add 0.4 parts of antistatic ionic liquid after dispersing evenly; finally add 0.8 parts of preservatives, 0.8 parts of antifungal agents, and 0.4 parts of thickeners in sequence, After uniform dispersion, the material is discharged, and the antistatic interior wall paint is obtained.

Abstract

The invention discloses an antistatic interior wall coating and a preparation method thereof. The antistatic interior wall coating is prepared from main components including deionized water, antistatic ionic liquid, ethylene glycol, cellulose, a dispersant, a wetting agent, a defoaming agent, carbon nanotubes, composite titanium dioxide, waterborne acrylic polyaniline and auxiliaries. The preparation method disclosed by the invention has the advantages that firstly, the waterborne acrylic polyaniline is adopted to replace a solvent type film-forming substance, and has the characteristic of static conductance while providing a proper system for a formula; in addition, the water-based environmental protection characteristic is in line with market demands; secondly, the composite titanium dioxide prepared by titanium dioxide for coating has the properties of a titanium dioxide pigment; besides, the production cost of the coating is reduced by using cheap filler as a core material; and meanwhile, the actual consumption of the titanium dioxide is reduced; thirdly, the added carbon nanotubes have the property that delocalized electron can spread along the axial direction in single-layergraphene, so that good electrical properties are achieved; by adding a small amount of the carbon nanotubes into a coating system, the antistatic interior wall coating is endowed with good electricalconductivity, so that an anti-static effect is achieved and the mechanical properties of the coating are improved.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an antistatic interior wall coating and a preparation method thereof. Background technique [0002] Static electricity cannot be effectively controlled under the current technical conditions. There is no suitable material to isolate and transmit it. It can move and store energy in insulating materials. Most of the means people use to protect it are to install shielding covers, or The ground wire releases it. Some experts pointed out that the static electricity generated by drying will indeed affect the brain. It will cause abnormal current conduction of nerve cell membranes, affect the central nervous system of people, and make people feel tired, irritable, insomnia, and headache. With the increase of household appliances and people wearing more chemical fiber clothes in winter, the static charge generated by household appliances will be absorbed and accumulated by ...
