Description

United States Patent SURFACE-PROTECTIVE FILM-FORMING MATERIALS Eugene D. Rudd, 3929 Cleveland Ave., St. Louis 10, M0.
N0 Drawing. Filed Oct. 9, 1957, Ser. No. 689,037
Claims. (Cl. 1062) This invention relates in general to coating compositions and, more particularly, to a surface-protective filmforming material.
During the spring, summer, and early fall, throughout most areas of the United States, the drivers of automobiles regularly encounter flying insects which strike against the forward portions of the vehicle and are killed immediately upon impact. The force of the impact usually causes the insect to be mashed against the surface of the paint or automobile finish and the rapidly flowing stream of warm air immediately dries the remains of the insect, leaving a hard, tightly adherent stain which is exceedingly difiicult to remove. In fact, most motorists, after driving for a few hours at night along a highway, will find that the radiator grill and other forward portions of the vehicle are literally covered with a heavily encrusted mass of insect stains which cannot be readily washed olf. Subsequent efforts to remove the insect stains after a few hours of night driving often necessitates the use of strong detergents which will destroy the wax finish or polish which has been applied to the surface of the vehicle and sometimes the removal of insect stains actually causes damage to the paint.
It is, therefore, the primary object of the present invention to provide a film-forming material which, when applied to an automobile finish, will coat the surfaces with a transparent water soluble and adherent protective film.
It is another object of the present invention to provide a coating composition which is adapted to form a film of the type stated, which film will resist penetration by dead insects and similar road-soil.
It is also an object of the present invention to provide a coating composition of the type stated which is Watersoluble and can be readily washed from a surface to which it has been applied without the use of detergents or strong solvents.
With the above and other objects in view, my invention resides in the novel means and processes of matter presently described and pointed out in the claims.
Broadly speaking, the present invention resides in forming an aqueous solution of a water-soluble material and a minute quantity of dispersing agent, the resulting aqueous solution being capable of drying upon the surfaces of an automobile to form a thin, transparent, watersoluble coating that can be washed away very readily and will carry with it any insect-remains or similar road-soil which may be present on the outer surfaces thereof.
It has been found in connection with the present invention that sodium carboxymethylcellulose may be incorporated in an aqueous solution together with a small percentage of a wetting agent of the anionic type, such as an alkyl aryl sulfonate. The resulting aqueous solution may be sponged, brushed, or sprayed upon the forward portions of the automobile, such as the radiator, radiator grill, and fenders, and will spread out smoothly to form a thin, transparent film thereon which dries readily and adherently to provide an invisible protective coating. Such coatings have been found to be impervious to the 2,986,471 Patented May 30, 1961 type of colloidal liquids resulting when bugs and insects are mashed against the forward portion of the vehicle. Consequently, the insect-remains, road-soil, and other similar extraneous material, will not penetrate to the automobile paint, but will be supported on the transparent fihn formed by the coating composition of the present invention. Subsequently, the coating composition of the present invention may be washed off by the simple application of water and all insect-remains, road-soil, and the like, will be immediately sluiced off as the coating composition dissolves and is washed away. The underlying paint surface will remain unblemished and undamaged. After the automobile has been washed, a new coating may be applied in the same manner as before.
By way of illustration, and not by way of limitation, the following are examples of coating compositions made in accordance with the present invention:
Example I Percent by weight Sodium carboxymethylcellulose (low viscosity) 5 Alkyl aryl sulfonate (Santomerse S) 0.5
Water, balance to make Example II Percent by weight Sodium carboxymethylcellulose (low viscosity) 7 Alkyl aryl sulfonate (Santomerse S) 0.8
Water, balance to. make 100%.
The materials can be formed into an aqueous solution substantially in the manner described in connection with Example 1.
Example III Percent by weight Sodium carboxymethylcellulose (low viscosity) 5 Sodium N-methyl-N-acyltaurate 0.10
Water, balance to make 100%.
The materials can be formed into an aqueous solution substantially in the manner described in connection with Example I.
Example IV Percent by weight Sodium carboxymethylcellulose (low viscosity) 5 Sodium hexadecyl sulfate 0.06
Water, balance to make 100%.
The materials can be formed into an aqueous solution substantially in the manner described in connection with Example 1.
Example V Percent by weight Sodium carboxymethylcellulose (low viscosity) 3 Sodium lauryl sulfate 0.03
Water, balance to make 100%.
The materials can be formed into an aqueous solution in the manner substantially described in connection with Example I.
Example VI Percent by weight Sodium carboxymethylcellulose (low viscosity) 5 Sodium Z-ethylhexene sulfonate 0.05
Water, balance to make 100%.
The materials can be formed into an aqueous solution in the manner substantially described in connection with Example I.
It has also been found in-connection with the present invention that non-ionic wetting agents may also be used, although slightly greater quantities are desirable. For example, formulations similar to those above specified have been successfully made and found to be efiective using such wetting agents as polyalkylene glycol ether, polyoxyethylene ether, alcohol, and'alkyl phenol ether.
Any one of the foregoing compositions of substantially similar nature can be applied in a thin, uniform transparent film upon the surfaces of the automobile vehicle and will dry to an adherent invisible protective coating, which will remain on the surface of the vehicle until washed away by water. Such coating compositions are extremely simple to use and are found to be relatively inexpensive. Furthermore, said coating compositions are eifective to protect the paint surfaces of the automobile 3. A transparent water-white coating composition capable of drying upon the surface of automobiles and the like to form a substantially invisible protective film thereon, said coating consisting substantially of:
Percent by weight Sodium carboxymethylcellulose 5 Sodium hexadecyl sulfate 0.05
Water, balance to make 100%.
from pitting or corrosion due to the acidic nature of many types of insect-remains and effectively forms a mechanical barrier between the insect-remains, road-soil, and the like, and the surface of the paint or other similar finish.
It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the surface-protective film-forming materials and in the steps of its production may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
1. A transparent water-white coating composition capable of drying upon the surface of automobiles and the like to form a substantially invisible protective film thereon, said coating consisting substantially of:
