Abstract
The self-depositing paint is prepared by using nanometer-level micro emulsion with high solid content as base material and mixing the base material with pigment, oxidant, ferrous fluoride or chloride, hydrofluoric acid or hydrochloric acid and proper amount of deionized water through stirring. The paint has excellent film-forming performance and easy-to-control self-depositing performance. It is used in coating metal base as well as small metal devices. Its use is favorable to environment protection.
Description
The invention belongs to chemical technology field, is a kind of preparation method of the autodeposition coatings based on the nano grade polymer dispersion.
Autodeposition coatings is a kind of class coating that does not need outside energy and can carry out application automatically in the metallic surface, existing in the world at present a large amount of patent is delivered, groundwork relates to two aspects: the one, prepare the method for autodeposition coatings, and the 2nd, the stability of autodeposition coatings system.About the preparation method of autodeposition coatings, mainly be to adopt back emulsification and self-emulsifying resin, and adopt the conventional emulsion polymerization method to prepare resin.Also there is not report based on the nano level autodeposition coatings aspect of micro-emulsion polymerization.For back emulsification and self-emulsifying resin, its molecular weight is lower, and the emulsifying resins wetting ability is stronger, so film forming need crosslinkedly just can obtain paint film preferably.And the molecular resin amount that emulsion polymerisation process obtains is bigger.But because particle is bigger, film-forming properties still is not fine, and wet film is not water-fast washes.The difficult control of the auto-deposition process of above-mentioned coating.
The objective of the invention is to propose the preparation method of the autodeposition coatings that a kind of good film-forming property and auto-deposition process be easy to control.
The preparation method of the autodeposition coatings that the present invention proposes, be a kind of be the preparation method of basic material with the high solid content nanometer microemulsion.This microemulsion forms pre-microemulsion, initiated polymerization, all the other monomers with hungry dripping method adding system by the partial polymer monomer earlier, continues prepared in reaction then and obtains.The solid content of this microemulsion reaches more than the 10-70wt%, and emulsifying agent is lower than 3wt%, and particle diameter is that (another application for a patent for invention of the visible applicant of preparation method, its Chinese application number is 10nm-60nm: 00116219.5).This is a kind of nano grade polymer dispersion.
In above-mentioned polymeric dispersions, the dispersible pigment color paste that adds the 1-20% (more excellent scope is 5-10%) of this polymkeric substance replacement, for example add 10% carbon black color slurry, the iron-holder that adds 0.5-50% (more excellent scope is 10-25%) is ferrous fluoride or the solution of ferrous chloride of 1-5%, the concentration that adds 0.5-20% (more excellent scope is 1-5%) is 10% hydrochloric acid or hydrofluoric acid solution, the concentration that adds 0.5-10% (more excellent scope is 1-5%) is 10% hydrogen peroxide solution, add proper amount of deionized water, stir and promptly make well behaved autodeposition coatings.Between the coating concentration control 5-30%.
The present invention is a basic material with the microemulsion of high solids content, because the special dimensional effect of microemulsion, the resin film-forming properties that makes is very good, and the wet film water-wash resistance is good.And the auto-deposition process is easy to control.
Coating of the present invention can be used for the application of metal base, can replace the electrophoresis coating method of existing vehicle paint base, can material saving, and safe in utilization, and help environmental protection.Such coating also is suitable for the application of smallclothes metal device, especially the application of the shell of air-conditioning and support and some similar devices.Coating process can replace existing powder coating mode, has simple, the easy to operate advantage of technology.
