Description
Patented Apr. 27, 1954 CORRO SIGN-RE SISTANT COATING Alfred L. Glass, Philadelphia, Pa., assignor to the United States of America as represented by the Secretary of the Navy No Drawing. Application August 5, 1952, Serial No. 302,857
6 Claims.
(Granted under Title 35, U. S. Code (1952),
sec. 266) The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.
This invention relates to a corrosion-resisting material and particularly relates to a material which is adapted to be used as a corrosion-resist ing coating for aircraft control cables or the like.
In the past, protection of aircraft control cables was attempted to be attained by mixtures of oxygenated higher hydrocarbons obtained from the residue of petroleum distillation together with various corrosion inhibitors. These compositions, however, were not able to withstand extreme conditions of temperature and when applied to the cable, became brittle at low temperatures approximating 67 F., and cracked and peeled from the cable as it was flexed over a pulley, thereby exposing the metal cable to corrosive conditions. At elevated temperatures, on the other hand, these compositions became tacky causing them to pick up dust and dirt and allowing grit to work its way into the strands of the cable. Furthermore, the color of these compositions varied from dark amber to black and, when combined with the dust and dirt picked up at high temperatures, provided complete opaqueness. Because of this opaqueness, if any corrosion developed beneath the coating, it was not possible to detect it in time to take any real preventative measures.
This invention was devised for the purpose of avoiding the objectionable features set forth above and generally comprises a mixture of vinylmethacrylate resins in low boiling solvents, properly plasticized to provide good flexing ability at low temperature conditions and to be sufficiently firm and hard at high temperature conditions. The composition is also lightly pigmented with a corrosion inhibitor which, however, leaves the composition substantially transparent. It is, therefore, one object of this invention to provide an anti-corrosive coating for aircraft cables or the like which exhibits the desired properties of flexibility and adhesiveness at very low temperatures and which also remains hard and firm at very high temperatures.
Another object of thisinvention is to provide an anti-corrosive coating'which' is substantially transparent.
Another object of this invention is to provide an anti-corrosive coating which is relatively cheap and easy to produce.
Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description and claims.
After a brief attempt at using wax and petroleum base type formulations which did not exhibit the desired properties, it was decided to explore the field of synthetic resins. It was believed that it would be possible to formulate coat ings, utilizing synthetic resins, that would exhibit the desired properties of low temperature flexing and adhesiveness and, at the same time, provide a hard and firm coating in the temperature range of 67 F. to +160 F. In such formulations involving synthetic resins these properties may be controlled through the choice and quantity of the proper plasticizer.
It has been found that several of the methacrylate polymers, when coated on metal, not only protect the metal from corrosion for great lengths of time and at high humidities but also exhibit good low temperature flexing and adhesiveness so that they act, in many ways, as their own plasticizer in a formulation. The particular methacrylate polymers which best exhibit these characteristics are n-butyl methacryiate, isobutyl methacrylate and n-propyl methacrylate polymers. Of these, the n-butyl methacrylate has been found to be the most preferable since it has the lowest softening temperature F.) and is, therefore, most flexible at the lower temperatures.
The resin n-butyl methacrylate, however, has a relatively low melting point and at elevated temperatures approximating FE, it forms a very soft film. In order to provide a harder coating at elevated temperatures, various vinyl chloride-vinyl acetate copolymers are added to the composition. It is known that vinyl coatings exhibit poor adhesion when applied to metal unless they are baked at fairly high temperatures, and since the control cables of an aircraft contain an internal lubricant which might be destroyed or caused to flow out when undue heat is applied, it is necessary to form the coating by airdrying and not baking. However, this difficulty is over come by using the vinyl chloride-vinyl acetate copolymer known industrially as VMCI-I. This composition consists of about 86 percent vinyl chloride, 13 percent vinyl acetate and about one percent of either maleic acid or maleic anhydride. The maleic acid or anhydride contains a polar bond which has a strong affinity for metal and, therefore, makes it possible to air dry the coating and yet obtain a strong adherence of the coating to the metal cable.
It was found that the above resins were best applied to a cable from a volatile solution. After testing various mixtures of solvents for these resins until the proper low boiling volatile solvents and their correct proportions were disccvered, it was determined that a solvent be used comprising a mixture of xylol, toluol and methyl isobutyl ketone in approximate proportions of l, 1 and 7. It was found to be necessary to use such low boiling volatile solvents in the solution so that the coating, when applied to a cable, would not flow off before it has had a chance to set up. In addition, all three of these solvents are substantially colorless liquids which would not tend to discolor the coating.
In order to use the vinyl polymer VMCH with the methacrylate resin, it is necessary to incorporate a plasticizer in the composition. The plasticizer must be of a nature to achieve the desired low temperature flexing and, at the same time, not produce a tacky film at elevated temperatures.
Various plasticizers fulfill the requirements to a greater or lesser extent. The polyethylene glycol di-Z-ethyl-hexoates of the general formula are found to be particularly satisfactory. A polyethylene glycol 400-di-2-ethyl-hexoate which goes by the industrial name of Flexol 4G0 and which comprises a blend of various ethylene glycol polymers, and Flexol 3G0 which is a tri ethylene glycol di-2 ethyl hexoate are commercially available and may be used. Another available plasticizer is Flexol TOF which is a tri-2 ethyl-hexyl-phosphate. The Flexol 4G0 is preferable to the others because it possesses the required characteristics over the greatest range. It gives a low temperature flexibility which is good at 4l0 F. and fair at -6'7 F. It also provides a non-sticky film at +160 F.
In order to improve the anti-corrosion qualities of the composition, a zinc potassium basic chromate of the formula K2O.4ZI1O.4CIO3.3H2O which is manufactured under the industrial name of Zinc Yellow Y-539-D is used. This product not only has high anti-corrosive qualities but also increases the adhesiveness of the composition to metal. This product has less basicity than the zinc chromate pigment ordinarily used as a corrosion inhibitor, and this is an important factor in the present composition since the maleic acid present in the VMCH vinyl polymer would react with the more basic zinc chromate to give an unstable product which would gel before being used. The Zinc Yellow Y-539-D is used in a quantity which is suflicient to provide the necessary corrosion inhibiting properties and which yet maintains the required transparancy of the film. This quantity comprises about one percent of the entire composition.
The various formulations are as follows:
Example 1 Parts VMCH (vinyl chloride 86%, vinyl acetate 13% either maleic acid or maleic anhydride 1%) to 102 N-butyl methacrylate polymer 40 to 4:2 Flexol 4G0 (polyethylene. glycol, 400
di-2 ethyl-hexoate) 33 to 35 Zinc Yellow Y-539-D(zinc-potassiumbasic chromate) 5 to 7 Xylol 50 to 60 Toluol 50 to 60 Methyl isobutyl ketone 2'75 to 375 Example 2 VMCH 100 to 102 Isobutylmethacrylate polymer so to 42 Flexol 4G0 33 to 35 Zinc Yellow Y-539-D' 5 to 7 Xylol 50 to 60 Toluol 50 to 60 Methyl isobutyl ketone 2'75 to 375 Example 3 VMCH 100 to 102 N-propyl methacrylate polymer 40 to 42 Flexol 4G0 33 to 35 Zinc Yellow Y539D 5 to "l Xylol 50 to 60 Toluol 50 to 6D Methyl isobutyl ketone 275 to 3'75 Example 4 VMCH 100 to 102 Methacrylate polymer 40 to 42 Flexol 3G0 (triethylene glycol di-Z- ethyl hexoate) 33 to 35 Zinc Yellow Y-539-D 5 to l Xylol 50 to 60 Toluol 50 to 60 Methyl isobutyl ketone 275 to 375 Obviously many modifications and variations of the present invention are possible in the light of the above teachings.
