Abstract
The invention belongs to the technical field of coating, specifically relates to an antistatic coating. The antistatic coating is characterized in that: the antistatic coating comprises the following components, by weight, 20-25 parts of a waterborne acrylic resin, 2-5 parts of flake zinc powder, 10-15 parts of copper powder, 3-5 parts of a antifoam agent, 3-5 parts of a thickening agent, 3-5 parts of a modifier, and the balance of water, wherein the waterborne acrylic resin is the film-forming substance, the flake zinc powder and the copper powder are the conductive fillers, the antifoam agent, the thickening agent and the modifier are the additives, and the water is the solvent. The particle size of the copper powder is 200 meshes. The shape of the conductive filler substantially affects the conductive property of the material, it is generally believed that the flake conductive particles have good conductive properties and the spherical conductive particles have poor conductive properties. With the present invention, the flake zinc powder is adopted so as to provide good conductive property; the zinc powder and the copper powder are combined so as to reduce the possibility of the copper powder oxidation; the copper powder with the particle size of 200 meshes is adopted, the particle size is the optimal selection, and the excellent conductive property is provided.
Description
Technical field
The invention belongs to coating art field, be specifically related to a kind of antistatic coating.
Background technology
Over nearly 10 years, electrically conducting coating has obtained development rapidly, and performance improves day by day, and kind increases day by day, has formed Antistatic Paint series basically.Antistatic Paint is existing multiple now, if divide with the electroconductibility composition, mainly containing charcoal is coating; Metal is a coating; Burning system coating adds [1] such as surfactant type coating, and along with the reinforcement of environmental consciousness; The electrically conducting coating that begins to pay close attention to environmental protection that People more and more is many, its prime advantage be eliminate or basically eliminate employed inflammable, explosive and be unfavorable for the organic solvent of environment protection in the general coating.Therefore, water-borne coatings is a direction of coatings industry development from now on.Prior art shows that electrically conducting coating generally uses graphite with filler, carbon black, or copper powder etc.Its price advantage of copper powder particularly conducts electricity goodly, more and more receives publicity, and it is promoted the use of but copper powder is prone to the oxidation restriction.The present invention provides novel antistatic coating, and its electrically conducting coating is zinc flake and copper powder, has effectively reduced the easy oxidation of copper powder and has brought adverse consequences.
Summary of the invention
The purpose of this invention is to provide a kind of antistatic coating.
A kind of antistatic coating, its characteristic is being made up of following composition by weight:
Filmogen: water-borne acrylic resin 20-25 part; Conductive filler material: zinc flake 2-5 part, copper powder 10-15 part; Auxiliary agent: skimmer 3-5 part; Thickening material 3-5 part; Properties-correcting agent 3-5 part; Solvent: surplus is a water.The particle diameter of described copper powder is 200 orders.
Its preparation method is: by the said ratio raw materials weighing, conductive filler material 85 ℃ of oven dry pre-treatment down, is mixed with the aqueous solution, auxiliary agent, filmogen according to the above ratio, again with the barreling mill evenly, the adjustment paint viscosity got Antistatic Paint after speed change stirred.
23 ℃ ± 2 ℃ of temperature, the constant-temperature constant-humidity environment of humidity 50% ± 5% is handled behind the 24h for use down with the corrugated cardboard of 50mm * 50mm.Coating mixed system viscosity is bigger; Can adopt coating roll (or glass stick) coating evenly to be coated on the cardboard of handling well; After treating drying at room temperature, place under 25 ℃, 50%RH fixed temperature and humidity to handle 24h and carry out performance test again, each sample is made 3 parallel samples.Coatingsurface resistivity is tested by military electromagnetic shielding material general specification GJB2604-96; Adopt the diagonal test method; Testing sample and electrode sections must clean, and are that the copper square electrode of 1cm * 1cm is connected the test of carrying out surface resistivity with volt ohm-milliammeter with homemade end face.
Water-borne acrylic resin, Guangzhou rice ocean trade Co., Ltd; Skimmer, thickening material, properties-correcting agent, dispersion agent, the wide safe chemical industry of Yixing City ltd.
Beneficial effect
1, the shape of conductive filler material has considerable influence to the conductivity of material, it is generally acknowledged that conducting particles is better in the form of sheets, and is spherical relatively poor.The present invention adopts zinc flake, and it is better to conductivity, because zinc powder and copper powder share, has reduced the oxidized possibility of copper powder simultaneously.Use 200 purpose copper powders in addition, its particle diameter is best selection, and it has good conductivity.
