Abstract
The invention provides a method for preparing a static conductive coating. The method comprises the following steps: 1, pre-dispersing nanoparticle materials, dispersant and organic solvent; 2, uniformly mixing the pre-dispersed materials and then dispersing at a high speed; 3, conveying the uniformly dispersed materials to a sand mill for sanding; 4, uniformly stirring and then filtering, depositing to obtain the static conductive coating. Being prepared from the nano materials, the static conductive coating has the advantages of stable static conductive performance, and the importance of the nano materials in the modern industrial production is reflected.
Description
Technical field
The invention relates to a kind of preparation method of static conductive coating.
Background technology
Static conductive coating has antistatic coating and Antistatic Paint, with the series of standards that country works out, adopt static conductive coating, static conductive coating is adopted from Industrial buildings and equipment de-sign, from the functional analysis of coating, coating can within the short period of time of 10-2 second, lead and let out static voltage savings, avoid producing the accident that electric discharge causes fire alarm or destruction electronic devices and components, and the generation of electrostatic and savings are nature outwardness, not opposing technical ability, the antistatic agent product of leading the theory of letting out was not measured for fabric, the accumulation of clothes electrostatic in wearing process can be prevented, storage tanker static conductive coating and protective coating is only told at this, structure (intrinsic) type static conductive resin is still in the pilot development stage in China, in production practice, application also has stretch to walk.Present static conductive coating is in synthetic resins, add a certain amount of conductive carrier, reaches the resistivity in certain limit and meet static conductive requirement after film forming.
Therefore the present invention have developed the method preparing static conductive coating by nano material.Nano material refers to the material having at least one dimension to be in nanoscale scope (1-100nm) or to be made up of as elementary cell them in three dimensions, and this is about as much as 10 ~ 100 atom close-packed arrays yardstick together.Because its size is close to the coherence length of electronics, great changes will take place because the strong relevant self-organization brought makes character for its character.Further, its yardstick is close to the wavelength of light, and add that it has the special effects on large surface, therefore its characteristic showed, such as fusing point, magnetic, optics, heat conduction, conductive characteristic etc., be often different from the character that this material shows when integrality.Nano-particle material is also called ultrafine particle material, is made up of nanoparticle (nano particle).Nanoparticle is also ultrafine particle, generally refer to the particle of size between 1 ~ 100nm, it is the transitional region being in cluster and macro object boundary, from common about microcosmic and macroscopical viewpoint, such system is atypical microscopic system also atypical macrosystem both, be a kind of typical Mesoscopic structure, it has surface effects, small-size effect and macro quanta tunnel effect.After macro object is subdivided into ultrafine particle (nano level) by people, it will demonstrate many unusual characteristics, and namely the character of its optics, calorifics, electricity, magnetics, mechanics and chemical aspect will have significant difference with comparing during bulk solid.And adopt nano material technology to carry out the process of metal-surface nano powder coating to mechanical key component, the wear resistance of mechanical means, hardness and work-ing life can be improved.
Summary of the invention
What the invention will solve is that traditional static conductive coating conductivity is low, the problem of poor stability.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is:
1. nano-particle material, dispersion agent and organic solvent are carried out respectively pre-dispersed;
2. by pre-dispersed mixing of materials evenly after in Circulatory Multi-step Ultrasonic Dispersion Machine, carry out high speed dispersion, the operating frequency of its high speed dispersion is 45-75KHz, and the working hour was at 3-8 hour;
3. uniform for high speed dispersion material is put into sand milling in sand mill, obtains the material that fineness reaches 50 μm of standards;
4. finally the material stirring that sand milling completes evenly is filtered afterwards, precipitating the solid obtained is the present invention.
Described organic solvent is that by volume per-cent is formulated by following component: N-BUTYL ACETATE 15%-55%, rosin based solder flux 55%-70%.
The advantage that the invention has and positively effect are: the static conductive coating that the method for the invention is prepared is significantly improved in stability.Also for the large-scale industrial application of nano-particle material has expanded new way.
