Definitions
- the principal object of the present invention is to provide an improved method as well as improved solutions for applying resinous, protective, flexible and impactresistant paint-bonding coatings on the surfaces of ferriferous, zinciferous and aluminiferous surfaces.
- Another object is to produce articles having a final siccative finish which are greatly improved as to appearance, corrosiou resistance and longevity.
- Solutions of such chromium compounds were referred to in the said application and will be hereinafter referred to as solutions of mixed chromium compounds and the preferred manner of preparing them, as disclosed in the said application, is by reacting an aqueous solution con- 'sisting essentially of from 50 to 800 g./l. of hexavalent chromium compound, expressed as CrO with from 0.03
- the polyacrylic acid compound may include both water soluble as well as water dispersible types.
- the word solution is to be understood as meaning dispersions as well asaqueous solutions.
- Water soluble types are readily available as standard articles of commerce, among which are the products known under the proprietary name of Acrysol.
- aqueous solutions of p-olyacrylic acids having different molecular Weights and viscosities are designated as AcrysolA-l and Acrysol-A-3.
- Water dispersible emulsions of polyacrylic acids are also commercially available and among these are those known as the Rhoplex AC-ZOO emulsions.
- alkali metal a'nd7or -prepared from all acid systems are also commercially available and among these are those known as the Rhoplex AC-ZOO emulsions.
- ammonium salts of polyacrylic acids are also available from various commercial sources.
- Acrysol and Rhoplex are trademarks registered in the name of the Rohm & Haas Company.
- polyacrylic acid compounds In addition to the polyacrylic acid compounds noted just above there also exist aqueous emulsions of acrylic esters called polymer latices such as those available under the designation EDX1, the latter being the trademark of the Reichold Chemical Company.
- polymer latices such as those available under the designation EDX1, the latter being the trademark of the Reichold Chemical Company.
- the minimum amount of mixed chromium compounds which must be present in the aque ous coating solutions of this invention is 0.25% by weight of the coating solution. Where less than 0.25% by weight of these mixed chromium compounds is utilized, the subsequently produced coatings will not provide the increased corrosion resistance otherwise obtainable by use of the teachings of this invention.
- polyacrylic acid content is concerned, this also must be present, as noted hereinabove, in an amount of at least 0.25% by weight of the coating solution. If less than 0.25% of polyacrylic acids are employed, no substantial improvement in coating properties will be realized. So far as the upper limit of polyacrylic acid is concerned, it has been found that no additional improvement, over those obtained initially, is experienced by the useof more than about by weight of the polyacrylic acids based upon the weight of the coating solutions. A preferred upper limit of 2% (by weight based onthe weight of the coating solution) of polyacrylic acids has been found on the basis of optimum results consistent with maximum economy of operation.
- the amount of mixed chromium compounds used may be as much as 10 parts thereof for each part of polyacrylic acid, it has been found, in the interests of economy, and to secure maximum efiiciency of operation, that the amount of mixed chromium compounds should range from about 0.5 part to about 5 parts thereof for each part of polyacrylic acid employed in the coating solution.
- the solution pH be maintained below about 2.3 since this pH level has been found to minimize substantially or to eliminate precipitation tendencies.
- the pH control may be accomplished through the addition of small increments of phosphoric or formic acids, and optimum blending is obtained when brisk agitation is employed throughout the mixing operation.
- compatible co-solvents may be added to the coating solutions of the present invention in order to improve the spreadability and viscosity flow characteristics thereof.
- co-solvents which have been found to be especially suitable for use in this respect include aliphatic alcohols and ketones containing up to four carbon atoms, and aliphatic ether alcohols containing from 4 to 8 total carbon atoms. Typical examples of these are the methyl, ethyl and buty-l alcohols, acetone, methylethyl ketone, and the mono and diethyl, propyl and butyl ethers of ethylene glycol.
- the amount of co-s'olvent to be employed may range on the surface to be treated it is preferable to apply a solvent cleaning agent before the solution is applied. If
- the metal to be coated is heavily contaminated with oil or dirt a stronger cleaning agent, such for example as sodium orthosilicate is preferably employed.
- a stronger cleaning agent such for example as sodium orthosilicate is preferably employed.
- the cleaning stage itself forms nospecific part of the present invention so it will suffice to state that conventional cleaning operations familiar in the art will be adequate for the purposes of this invention.
- the coating solution is preferably applied at average living room temperatures, i.e., in the neighborhood of 72 P. which obviates a need for maintaining heated coating baths and heating equipment. Nevertheless, if desired, the baths of this invention may be applied at elevated temperatures without deleterious effect upon the quality of the resulting coatings.
- the baths may be applied to the metal surfaces by dip, spray or roller coating techniques, the important consideration, of course, being that the entire surface area be adequately and thoroughly wetted by the bath.
- a suitable wetting agent While various cationic, anionic or non-ionic Wetting agents have been found to be suitable for use in this respect, the preferred types are the non-ionics, typical of which are the polyethoxylated alkyl phenols containing from 6 to 12 ethylene groups, and from 8 to 9 carbon atoms in the alkyl group.
- the surface should be subjected to a drying operation.
- This drying serves to cure the mixed organic-inorganic coating and, of course, the length of the drying step will depend upon the temperature utilized. Naturally, if the temperature is rather low a relatively long period of time will be necessary to effect a complete cure whereas, if the temperature is somewhat elevated, the drying and curing can be accomplished in less time.
- a preferred range of temperatures for the drying operation lies anywhere from about 200 to 350 F. because it has been found that temperatures within this range yield especially good results.
- a coating produced in the manner just described is extremely useful per se and for some purposes will be all that is required.
- a siccative finish is generally applied to the coated surface and where this is desired the following technique may be employed.
- the coated surface preferably, is at least surface dried but before drying is sufficiently complete to effect the required .cure, the siccative film may .be app-lied, following which a single baking step may be employed which will serve to completely cure the coating of the present invention while simultaneously effecting the'customary baking of the siccative finish.
- drying temperature is from approximately 200 to 350 F.
- drying temperature is from approximately 200 to 350 F.
- An aqueous solution for coating metal surfaces consist essentially of I (1) .at least 0.25% by weight of reaction products derived from the admixture of an aqueous acid solution consisting essentially of from about 50 to about 800 gms./liter of hexavalent chromium, expressed as CrO with from about 0.03 mol to about 1 mol of formaldehyde, expressed as HCHO, for every mol of hexavalent chromium and (2) at least 0.25% by weight of water-soluble and water-dispersible polyacrylic acid compound chosen from the class which consists of the said acid, the alkali metal and ammonium salts thereof and aqueous emulsions of acrylic esters known as polymer latices.
- component (2) consists of acid components from the said class.
