United States Patent 3,573,212 CLEANSING COMPOSITION AND METHOD Rafael Foguet Ambros, Flix, Spain, assignor to Electr0- Quimica de Flix, S.A., Barcelona, Spain No Drawing. Filed Jan. 9, 1968, Ser. No. 696,511 Int. Cl. Clld 1/18, 1/38, 1/50, 3/26 US. Cl. 252-153 9 Claims ABSTRACT OF THE DISCLOSURE A cleansing composition for removing oils, greases, dust, dirt as well as water from non-porous objects to prepare them for phosphatizing, electroplating, enameling, glazing, lacquering or painting which comprises a chlorinated ethylene such as trichloroethylene or perchloroethylene, from 0.1 to about 1.5 percent by weight of a non-ionic surface active agent, such as an addition product of ethylene oxide with an alkyl phenol, fatty alcohol or fatty acid, and preferably 2 to 100 parts per million of an amine fixer, e.g., an aliphatic or aromatic amine. The method of cleansing involves immersing the objects in this composition while it is boiling and then transferring them to a boiling, pure chlorinated hydrocarbon.
The importance of the chlorinated solvents, trichloroethylene and perchloroethylene in modern industry is well known. Fundamentally these are the solvents which otherwise are generically known as metal degreasers, although the method also applies to non-metallic objects.
The material to be degreased consists of finished or semi-finished objects of all kinds which have been manufactured with the aid of cooling, cutting or lubricating products. Sometimes the surfaces are contaminated by shavings, sawdust, oils, greases, talcum, etc. which must be removed completely.
It is frequently necessary, in the metal working industry, e. g., in the manufacture of electrical appliances, metal coverings, automobile accessories, photographic apparatus, engravings, jewelry and costume jewelry, clocks and Watches, metal locks, bearings and apparatus in general, as well as in the electrical industry, to have recourse to surface treatment preliminary to phosphatizing, electroplating, enameling, glazing, lacquering or even mere painting.
All these techniques are based on adherence and compactness of the coating which is directly influenced by the cleanliness of the surface to which it is applied. Any dirt or spot of moisture makes the coating defective no matter how soundly and carefully it is carried out.
It is customary in the surface treatment of such objects to use aqueous solutions, including even water, to eliminate traces of acids or alkalis. For a quality coating, any water remaining on the object to be treated is as damaging as the dirt which was previously removed. The adherence of a protective layer is excellent only when it is applied to an absolutely clean surface, free of water and the salts dissolved therein, which at times form spots.
One conventional manner of drying, namely blowing with hot air or combustion gases, does not provide a satisfactory solution for this problem. Although it causes evaporation of the water, the salts dissolved therein remain on the object and form the above-mentioned undesirable spots.
The use of organic liquids (non-chlorinated solvents) Which have an affinity for water and which have a high vapor tension at low temperature to facilitate rapid drying, enormously complicates the problem since in general these liquids are combustible and excessively light. Their use requires special closed apparatus provided with safety mechanisms in order to avoid accidents. Conventional sol- 3,573,212 Patented Mar. 30, 1971 vents for the degreasing of metals, i.e., chlorinated hydrocarbons such as trichloroethylene and perchloroethylene, have the advantage of making it possible to work with open apparatus due to the substantial density of their vapors. However, these two solvents in themselves have little affinity for water and therefore act very slowly to eliminate water adhering to the surface of an object, even at temperatures above room temperature.
It has now been found that it is possible to increase the affinity of such solvents for water by the addition of a wetting agent and preferably also a pH fixing agent. In the cleansing method of the invention, the object contaminated by water or other contaminants is immersed in a boiling mixture of solvent, wetting agent and pH fixer. The water passes rapidly into the mixture and is eliminated by azeotropic distillation.
Satisfactory results are in particular obtained when using, for the cleansing and drying of non-porous objects which contain water or aqueous solutions, compositions consisting of a chlorinated ethylene, a non-ionic surfaceactive agent and a pH fixer.
Large amounts of additives to the solvent are not necessary to obtain good results; from 0.1 to 1.5% by weight of non-ionic surface-active agent and from 2 to parts per million, by weight, of amine fixer are sufiicient.
Specifically, small proportions of additives must be used to avoid formation of emulsions and to permit rapid volatilization of the water together With the solvent forming the heteroazeotrope of minimum boiling point.
The non-ionic surface-active agents employed include for instance oxyethylated products derived from alkyl phenols, fatty alcohols of oxyethylated greases or derivatives of greases in general; among them the addition products of ethylene oxide (from 4 to 30 mols per mol) to nonyl phenol, addition products of ethylene oxide (20 to 50 mols per mol) to tributyl phenol, addition products of ethylene oxide to octyl phenol, addition products of ethylene oxide (more than 10 mols per mol) to lauric and myristic alcohols, or to their mixtures, addition products of ethylene oxide (from 18 to 42 mols per mol) to castor oil, and addition products of ethylene oxide to oleic acid deserve special mention.
pH fixing agents that are useful in the composition and method of the invention include, by way of example, aliphatic amines such as triethyl amine, triethanolamine and diisopropyl amine, aromatic amines such as phenyl amine, diphenyl amine and naphthylamine.
The choice of trichloroethylene or perchloroethylene depends on various factors. Trichloroethylene must be avoided for treatments of aluminum and light metals, while perchloroethylene does not offer any chemical incompatibility. On the other hand the use of perchloroethylene requires baths of higher temperature because of the higher boiling point C.) of perchloroethylene.
The apparatus for carrying out the drying of nonporous objects are those normally used in the treatment of metal surfaces; i.e., apparatus having one vessel or chamber containing the drying mixture and another containing pure solvent, both being maintained at the boiling point. The azeotropic mixture distilled from the first vessel or chamber passes to a water-solvent separator which returns the solvent to the chamber and eliminates the water.
EXAMPLE A drying solution is formed by adding to trichloroethylene or perchloroethylene A. from 0.1% to 1.5% nonionic surface-active agent, such as an addition product of ethylene oxide (from 4 to 30 mols per mol) to nonylphenol; an addition product of ethylene oxide (20 to 50 mols per mol) to tributyl phenol; an addition product of ethylene oxide to octyl phenol; an addition product of ethylene oxide (more than mols per mol) to lauric or myristic alcohols or a mixture thereof; an addition product of ethylene oxide (from 18 to 42 mols per mol) to castor oil; or an addition product of ethylene oxide to oleic acid, and B. from 2 to 100 parts per million of an amine such as triethyl amine, triethanolamine, diisopropyl amine, butylamine, phenyl amine, diphenyl amine or naphthylamine.
This solution is maintained at a boil and the non-porous objects to be dried are immersedin it. In general 10 to 50 seconds is sufficient to eliminate the water or the spots thereof. The residues of the surface-active agent are removed by immersion in a second chamber containing pure solvent at the boiling point.
