Description
Technical field
The invention discloses a kind of preparation methods of anti-static coatings, belong to technical field of polymer materials.
Background technique
Using polymer matrix composites as nonmetal structure/functional material of representative there is light, performance can design, easily in batches
The features such as production, application range are growing.The volume resistivity of polymer matrix composites is higher, generally higher than 109 Ω cm,
Surface by air-flow, solid particle and liquid friction and shock when, be also easy to produce and accumulate electrostatic.Accumulation of static electricity reaches certain journey
Degree, will cause static discharge, cause the breakdown of instrument and equipment component to be scrapped, control system failure, accuracy at target reduces, seriously
When have cause weapon system explode danger, cause serious accident.Simultaneously as accumulation of static electricity, composite material surface is easy to inhale
Dust in attached air, and be difficult to thoroughly it is cleared, influence product appearance.
Anti-static coatings are coated, anti-static coating is formed, are the effective measures for eliminating composite material surface electrostatic.Coating
When volume resistivity is less than 107 Ω cm, the electrostatic charge of generation can be dissipated with moment, will not be accumulated, because higher without causing
Electrostatic field.The anti-static coatings of actual use, volume resistivity general control have preferable warp in 104~107 Ω cm
Ji property and craftsmanship.Whether anti-static coatings are made of film forming matter, paint filler, auxiliary agent and solvent, led according to film forming matter
Electricity can be divided into Intrinsical anti-static coatings and addition type anti-static coatings.Film forming matter itself is conductive, is not required to addition and leads
Electric component, this coating are known as Intrinsical anti-static coatings；Film forming matter itself is insulator, since addition filler or auxiliary agent make
Coating has antistatic performance, and this coating is known as addition type anti-static coatings.
Addition type anti-static coatings are made of conductive filler (pigment), insulation film forming matter, auxiliary agent and solvent, electric conductivity
Can be related with the resistance of conductive filler, it is related with volume fraction of the conductive filler in paint film, it is also related with environment temperature.Due to
Film forming matter is insulator, and conducting particles must be in contact with each other or closely in dry film, electronics can just overcome between particle at
The blocking of membrane substance forms electric current, therefore the volume fraction of conductive filler is generally very high.Conductive filler can be divided into metal class, carbon
Class, metal oxide-type, inorganic salts, conductive polymer subclass and organic salt.The most study that metal class conductive filler is subject to,
Using most mature, but it is universal oxidizable, and color is deep, can not prepare white or light-colored anti-static coatings；Carbons conductive filler is conductive
Property it is good and stablize, but color is single, can only prepare dark paint；Metal oxide-type and inorganic salts conductive filler it is common
Feature is stable conductivity, and color is shallower, is the direction developed in recent years, but resistivity is higher；Conductive polymer subclass conduction is filled out
Expect best with the compatibility of matrix resin, be conducive to the raising of coating mechanical mechanics property, but its preparation process complexity, cost compared with
It is high；Organic salt conductive filler belongs to surfactant, relies primarily on the coefficient of friction and adsorbed water molecule for reducing coating surface
And antistatic, effect are poor.
It is current to there is researcher to mix following ingredients in the prior art, 25% modified epoxy (mass fraction, under
Together), 5% curing agent, 70% silver-colored packet glass microballoon (silver content 30%), solvent are the mixed solution of n-butanol and dimethylbenzene, are dried
Dry temperature 60 C, drying time 2h.Thus the epoxy conductive corrosion-inhibiting coating that technique obtains is creamy white, and film is smooth, resistivity
For 0.03~0.05 cm, 2 grades of adhesive force.There are also researchers to use substep mixing method, by diatomite, concavo-convex rod soil, conduction
Mica powder, nanometer iron powder, talcum powder conducing composite material are mixed together so that between the different five kinds of substances of granularity, density with
The network connection of diatomite, concavo-convex rod soil, conductive mica powder and nanometer iron powder is got up, is uniformly mixed as skeleton by talcum powder, from
And guaranteeing prepared coating uniformity, application performance is good, static conductive excellent effect.But antistatic traditional at present applies
Material, since there are biggish interface resistances between each conductive filler, cause the antistatic performance of coating bad, therefore also need to its into
Row research.
