7 Claims. (Cl. 117--85) This invention concerns corrosion-resisting coatings for steel, particularly high butyryl cellulose acetate butyrate coatings As steel has become more and more expensive the problem of losses through corrosion has become increasingly important, and various means have been tried to solve this problem. One important method of treating this problem has been cathodic protection wherein an impressed Current is supplied from a rectifier or generator to the steel member in order to decrease the galvanic action which is responsible for corrosion, particularly to protect underground pipe. Another remedy has been metallic coatings applied over iron, for instance, Zinc or tin which play a sacrificial role in protecting the iron. Clad coatings such as stainless steel or nickel bonded to steel have been used but are expensive. In addition,, glass, porcelain, and cement have been used but suffer from defects such as difficulty in handling and susceptibility to shock damage.
Coatings of the film or skin type such as those from paints of different types have been subject to many disadvantages such as lack of adhesion, susceptibility to corrosion through pin holes in the coating, breakdown of the chemical structure of the coating or inability to withstand the effects of temperature changes or moisture as a result of swelling due to water absorption.
We have discovered a coating which incorporates the desirable advantages of low cost, excellent adhesion, and good durability. Moreover, this coating is easy to apply by spray, dipping and roller coating, and can be made to have a high gloss surface of a pleasing ornamental nature. It can be used alone or as part of a coating system.
One object of this invention is to provide a corrosion resisting coating for steel comprising high butyryl cellulose acetate butyrate. Another object of this invention is to provide a paint suitable for coating metallic surfaceshaving excellent adhesion and pleasing ornamental qualities. A further object is to provide a primer for coating iron and steel which will protect the metal against corrosion and serve as a base for cellulose acetate butyrate coatings. Another object is to provide coating systems having a cellulose acetate butyrate base which protects steel against corrosion.
The above objectives are attained by the use of lacquers containing as the coating ingredients from about 40% methylol phenyl allyl ether and 60-95% cellulose acetate butyrate. We have found that this combination with a properly constituted solvent mixture provides a coating for steel which has high resistance against corrosion. In our preferred embodiment we use a high butyryl cellulose acetate butyrate which has an acetyl content of about 13%, butyryl content of about 37%, hydroxyl content of about 2% and intrinsic viscosity in acetone from about 0.5 to 2.0. This cellulose acetate butyrate has good compatibility with the allylated methylol phenol when used with a carefully compounded solvent mixture. For instance, we have found that a mixture such as one with 30% xylene, 25% toluene, 12% butyl 'ice alcohol, 15% isopropyl alcohol, and 18% butyl acetate is satisfactory. We also find that at least 0.3% phosphoric acid based on the solids content must be added for rapid curing of the coating.
Another embodiment of our invention is illustrated by coating systems in which a primer is used comprising cellulose acetate butyrate, a compatible solvent mixture, and zinc tetroxychrornate. The cellulose acetate butyrate allylated methylol phenol coating may then be applied directly upon the primer followed by a top coat or series of top coats if desired.
In the diagrammatic illustration of our invention, Figures 1 and 2 are longitudinal sectional views through a lacquered coating on a steel surface.
In Figures 1 and 2, a steel surface 1 carries a primer 2 comprising cellulose acetate butyrate and zinc tetroxychromate. Over this primer coating 2 is placed a cellulose acetate butyrate coating 3 containing methylol phenyl allyl ether. A third coating 4, as illustrated in Figure 1, may be added, comprising cellulose acetate butyrate.
The following tables illustrate the preferred embodiment of our invention but are not meant to be limiting in nature.
TABLE I Cellulose acetate butyrate compositions in corrosionproofing of steel i toluene, 10% methyl Gellosolve, 20% #1 ethyl alcohol. b xylene, 25% toluene, 12% butyl alcohol, 15% isopropyl alcohol, 18% butyl acetate.
