Abstract
The invention relates to a solventfree epoxy conductive coating paint taking electric conduction mica powder as conducting medium. The coating paint comprises the ingredients with the range of mass percent: 25.12-47.53% of epoxide resin, 1.75-3.96% of accessory ingredient, 0.99-6.23% of pigment, 20.33-33.62% of electric conduction mica powder, 2.00-6.71% of reactive diluent, 13.04-23.67% of curing agent and the rest of filling material. As the coating paint is added with the electric conduction mica powder and ensures the arrangement of tens of layers of electric conduction mica powder, a complicated and zigzag permeation and diffusion path is formed, and permeation and diffusion route of corrosion medium becomes to be rather zigzag and bended; therefore, the coating paint is not easy to permeate to the base material, thus having better penetrability resistance; meanwhile, the mica powder can be closely arranged in a tiling way to form continuous conducting layers.
Description
Technical field:
What the present invention relates to is a kind of non-solvent epoxy conductive paint that adopts conductive mica powder as conducting medium, particularly be to be applicable to need heavy anticorrosion inner wall of oil tank and the thick non-solvent epoxy conductive paint that is coated with antistatic terrace place.
Background technology:
Adopt conductive mica powder to contain more organic solvent as the solvent-borne type electrically conducting coating of conducting medium, these organic solvents enter atmosphere in the production and the construction stage of coating, contaminate environment, the health of harm humans simultaneously.Because environmental regulation is strict day by day, the solvent-borne type product is eliminated gradually; Is not a successive electrical conductor and adopt electro-conductive fiber as the solvent-free electrically conducting coating of conducting medium itself, need could form a successive electrical conductor by conductive primer, its construction technology complexity, and, cause the paint film conductive profile inhomogeneous because electro-conductive fiber should not disperse.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of compliance with environmental protection requirements, antiseptic property excellence, construction technology simple and have than high performance-price ratio a kind of and adopt conductive mica powder as the non-solvent epoxy conductive paint of conducting medium and this employing conductive mica powder preparation method as the non-solvent epoxy conductive paint of conducting medium.
Concrete technical scheme of the present invention is as follows:
A kind of non-solvent epoxy conductive paint that adopts conductive mica powder as conducting medium, described coating composition is made up of low molecular weight liquid epoxy, auxiliary agent, pigment, conductive mica powder, reactive thinner, filler and the solidifying agent of bisphenol A-type, shared mass percent scope is: the low molecular weight liquid epoxy 25.12～47.53% of bisphenol A-type, auxiliary agent 1.75～3.96%, pigment 0.99～6.23%, conductive mica powder 20.33～33.62%, reactive thinner 2.00～6.71%, solidifying agent 13.04～23.67%, filler are surplus.
The low molecular weight liquid epoxy of described bisphenol A-type, its resistivity is less relatively, and low, the easy solvent free of viscosity.
Described filler is talcum powder, silica powder or two kinds mixture wherein.
Described reactive thinner, it participates in curing reaction, and volatile quantity is little.
Described solidifying agent is a modification cycloaliphatic amines compound.
Described auxiliary agent is defoamer, flow agent, three kinds of mixtures of material of Ricinate.
Apply the planeness of rear surface and the uniformity coefficient of color for improving coating, the ratio of the defoamer in the described adjuvant component, flow agent, Ricinate quality is preferably: 1:0.5～1.2:2～3.
Described pigment is white pigment, black pigment, inorganic color(ed)pigment, organic color pigment or wherein two kinds or two or more mixtures.
Described conductive mica powder is the mica powder through surperficial coated with conductive medium, the thickness of this conductive mica powder is at 0.2～1 micron, can guarantee in coating, to have the arrangement of tens of layers conductive mica powder like this, form complicated zigzag infiltration the evolving path in the coating, make the scattering and permeating route of corrosive medium become quite tortuous crooked, be difficult to be penetrated into base material, make coating have better permeability resistance; This mica powder arrangement of can tiling closely simultaneously forms continuous conducting layers, and dope layer to form the rear surface smooth, smooth, color is even.
Embodiment:
