Abstract
A method and composit ion for cleaning and protecting vinyl, rubber and leather surfaces. The composition comprises a water-based emulsion of acrylic copolymer of RHOPLEX® HA-12, manufactured by Rohm and Haas of Philadelpha, Pa., polyethoxylated alkylphenol, and ammonium hydroxide. The ammonium hydroxide prevents coagulation that otherwise can result from freezing and thawing the composition. Application of the composition to aged and faded vinyl., rubber and leather surfaces cleans and restores the original luster and color without leaving an oily or glossy film.
Description
~ ~ i 7.~~~1 VINYL SURFACE CLEANSER AND PROTECTANT
Background of tyke Invention Field of the Invention This invention relates generally to the field of protectant compositions for use on vinyl, leather and rubber surfaces, especially in autornobiles, as well as to the field of compositions for cleaning the same. In particular, this invention related to vinyl protectant formulations that reduce the oily appearance and feel commonly experienr_ed with the use of such products, and to protectants that incorporate a nonionic surfactant, such as trimethyl.nonylphenyl polyethylene oxide).
Background of tyke Invention Field of the Invention This invention relates generally to the field of protectant compositions for use on vinyl, leather and rubber surfaces, especially in autornobiles, as well as to the field of compositions for cleaning the same. In particular, this invention related to vinyl protectant formulations that reduce the oily appearance and feel commonly experienr_ed with the use of such products, and to protectants that incorporate a nonionic surfactant, such as trimethyl.nonylphenyl polyethylene oxide).
2. Desr_ription of the Prior Act Because of their durability, light weight and relatively low cost, vinyl polychloride polymer and a variety of plantis materials are commonly incorporated into components of motor vehicle interiors, such as dashboards, door linings, steering wheels and gear Shift levers. Unless they are preserved by a suitable film of protecta.nt, the surfaces of such components oxidatively degrade over time, particularly if they are routinely exposed to sunlight, resulting in loss of their original luster and gradual fading of their colors. It is highly desirable that such protectants not leave an oily appearance or feel, particularly as to those components that are frequently manipulated by a driver, such as steering wheels and shift levers. It is also important that protectants applied to automotive interiors not produce so 722f7-7 ., much gloss as to interfere with a driver's vision.
Protectants in the prior art within the field of this invention include the following:
U.S. Patent 5,227,200 to LeGrow disclosed a rnethod far protecting automotive vinyl; rubber and leather surfaces by applying to the surfaces a protectant composition that includes an alkylaryl polysiloxane copolymer having long chain hydrocarbon units and aromatic units. In one form of the composition, the alkylaryl polysiloxane was emulsified in water with the aid of a nonionic surfactant, such as trimethylnonylphenyl polyethylene oxide). In a solvent solution forrn of the composition, the alkylaryl silicone was dissolved in a volatile carrier, preferably heptane. In a third forrn of the cornposition, an alkylaryl polysiloxane fluid was used without any additives. Advantages claimed for the composition included enhanced affinity for organic surfaces such as rubber and vinyl; greater substantivity and ultraviolet protection, and increased ability to repel water and to be easily flushed clean with water.
U.S. Patent 5,217,758 to Gre2nleaf et al. disclosed a method for providing a protective finish to a vinyl substrate key ttie application of a cornposition cornprising a film forming polysiloxane, a diluent, and a wax in the form of micronized particles. Suitable diluents disclosed included water, toluene, mineral spirits and isopropanol. In an alternative ernbodirnent, the composition included an amorphous silica in the form of fumed silica particles. Advantages 1 ~' i .S~'~

U.S. Patent 4,759,955 to Hsu et al. disclosed a method for restoring, protecting and enhancing polymeric substrates, and in particular vinyl coverings, by applying a composition comprising an acrylic palyrner, benzotriazole, and a solvent therefor. The preferred acrylic polymer disclosed was the rnethylrnethacrylate polyrner sold under the "Acryloid"
trademark, product designation B44 and B48N by the Rohm & Haas Company of Philadelphia, Pa. Benzatriazale was included in the composition to serve as an adhesion promoter. Advantages reported for use of the cornpasition as applied to vinyl surfaces included fihe ability to restore and enhance the appearance of vinyl surfaces coated by polymers such as vinyl fabrics, restoration of original color of aged vinyl surfaces, and an excellent resistance to ultraviolet light and yellowing with age.
Rohrn and Haas of Philadelphia, Pa., has manufactures and sold an acrylic copolymer emulsion under the trademark RHOPLEX HA-12, which has been known to form firm, tack-free films suitable for fabric finishings, backcoating, and other applications where abrasion resistance was required. Use of this acrylic copolymer in a vinyl surface protectant has suffered, however, from the disadvantage that it coagulates if stored at ambient temperatures below the freezing point of water, rendering it thereafter unsuitable for t.xse as a protectant .
2i ~'i:~~9 _g_ Although acrylic polymers; including RHOPLEX~HA-12 used in ttie present invention, are known in the art, their use is believed to be new in a composition that simultaneously elirninates the coagulation problern due to freezing, provides a non-oily appearance and feel, avoids excessive gloss, and provides surface cleansing during application.
SUt~IARS~ OF THE INVENTION
It is an object of the present invention to provide an improved acrylic copolymer containing autornotive vinyl, rubber and leather protectant iri the form of a water-based emulsion.
It is an object of the present invention to provide a protectant composition that does not coagulate if frozen and thawed.
It is an object of the present invention to provide a protectant composition that contains a cleansing agent such that application of the protectant to a vinyl, rubber or leather surface simultaneously cleans the surface and leaves a protective film on the surface.
It is an object of the present invention to provide a protectant composition that restores the original luster and color when applied to aged vinyl surfaces.
It is an object of the present invention to provide a protectant composition that is antistatic, and does not produce excessive gloss, when applied to vinyl, rubber and 21 ~'7~~9 leather surfaces.
These and other objects, features and advantages of the present invention will become more apparent from a consideration of the following detailed description thereof.
DETAILED DESCRIPTION OF THE INDENTION
c RHOPLEX HA-12 is a self crass linking acrylic copolymer emulsion composed of 44-46 percent by weight acrylic copolyrner, water 54-56 percent by weight, 0.05 percent by weight formaldehyde, and trace amounts of individual residual monomers. It is a rnilky white fluid having pH 2.1 to 4.0, viscosity 100 to 750 centipoise, specific gravity 1.0 to 1.2 relative to water, and it is dilutable in water. The chemical structure of the acrylic copolymer in RHOPLEX HA-12 emulsion is a trade secret of Rohm and Haas, Inc., of Philadelphia, Pa.
The minimum recommended storage ternperature for this material is 1C/34F because freezing and thawing it can cause it to coagulate.
In the preferred embadirnent, the protectant composition of the present invention is a mixture of IO-17 n percent by weight of acrylic copolymer of RHOPLEX HA-12, 0.5-1.5 percent by weight of polyethoxylated alkylphenol, 0.2-1.0 percent by weight of ammonium hydroxide, and the balance of the composition comprises water. The arnmoniurn hydroxide is ner_essary in order to prevent coagulation in the event of freezing and thawing of the composition. Too much arnmonium hydroxide, however, is counterproductive as it would raise the L~ i i.SLy :, _ pH of the composition out of the desired range of 3.5 to 7Ø
The corn~?osition preferably also includes a foarn inhibitor such as polypropylene glycol in sufficient amount to inhibit foarn formation. for exarnple; PLURONIC~61, manufactured by BASF
Corporation of Parsippany, New Jersey. The polyethoxylated alkylphenol is a nonionic surfactant that facilitated removal of dirt as the cornposition is being applied to a surface, for example by rubbing with a soft cloth. A suitable source of polyethoxylated alkylphenol is IGEPP.L CO 730 GAF, or alternatively, 1:NTAROX~L61, manufactured by Rhone-Poulenc of Cranbury, New Jersey.
The following examples are set forth for the purpose of further illustrating the concepts of the invention.
E~~ANIPLE 1 A 12 gallon batch of the protectant composition was prepared in a well ventilated facility by the following steps:
diluting 1.2 lbs. Igepal CO 730 GAF in 7.98 gallons of water;
blending into the diluted Igepal 3.66 gallons of RHOPLEX HA-12 ernulsion;
adding Pluronic 61 to eliminate any foam;
adding four ounces of an aqueous solution of ammonium hydroxide (29.4 percent by weight); and filling plastic containers with the resulting emulsions by tube frorn the bottom in order to avoid introducing air bubbles. Freezing and thawing the resulting composition did not cause coagulation.
21 ~' 7329 The resulting protectant composition was applied by rubbing with a soft cloth to a soiled and faded, blue vinyl-coated fabric obtained from the interior of a 1979 Datsun autornobile. The original blue solar and luster were restored to the fabric and a non-glossy; non-oily finish was obtained.
Touching the finish with the fingers left no evident f fingerprint s .
The composition of example 1 was applied by soft cloth to the steering wheel of a 1986 Honda Accord automobile.
After the composition had dried, it was observed that the steering wheel had a matte finish that was not oily or slippery.
The composition of Example 1 was applied to the dashboard of a 1994 Mitsubishi Expo LRV mini-minivan. There was no noticeable increase in light glare in the windshield area f rorn sunl fight ref lest ed f corn the dashboard .
The present invention has been disclosed in connection with preferred embodiments thereof, one of ordinary skill will be able to effect various alterations, substitutions or equivalents and other changes without departing from the spirit and scope of the invention as disclosed. It is therefore intended that the scope of Letters Patent granted hereon be limited only to the definition contained in the a~?pended claims and equivalents thereof.
