PAINT REMOVAL COMPOSITION AND SYSTEM
Cross-Reference to Related Application
This application is a complete application of U.S. Provisional Application Serial No. 60/054,123 filed July 29, 1997 and is disclosed in Disclosure Document No. 413,959 filed July 17, 1997 retention of Disclosure Document No. 413,959 is requested.
Technical Field
This invention relates to compositions for removing paint and, more particularly this invention relates to an environmentally safe paint removal composition based on organic surfactants and polymeric organic solvents.
Background of the Invention
Traditionally, paint removers have been based on organic solvents. However as the toxic and environmental effects of volatile organic compounds ( VOC ) and halogenated solvents have been recognized, regulations have been promulgated to remove these ingredients from solvents. The reformulated paint remover products on the market are difficult to use and are not very effective in removing paint from a surface. This is especially true for granular, rough surfaces. Some of the products also contain metal salts impurities such as nitrates, sulfates or phosphates which can irritate skin and are not suitable for normal disposal. The products must be disposed of as hazardous waste. Also, prior paint remover products have high or low pH again causing irritation to skin and waste disposal concerns. Some products contain organic solvents having low flash points, high contents of VOC and are flammable. Data on some organic solvents used in paint removers follows :
F = flammable T = toxic X; = irritant Xn = low irritant
There is an epidemic of spray painting graffiti onto the walls of buildings, fences, traffic signs, sidewalks, etc. in the United States. Many of the walls are finished with a rough, relieved finish. The spray paint is propelled into the relief of the wall and is very difficult to remove except by sand blasting. Most of the time, the graffiti is not removed. It is covered with a patch of paint. Usually, the patches of paint do not match the paint surrounding and adjacent the patch creating an unattractive pattern of different colored areas on the wall.
Another environmental problem has created demand for paint removal. Many old buildings contain surface painted with paints that contain lead. Studies have demonstrated that children who live in housing containing lead paint have high levels of lead in their blood which can interfere with brain development.
STΛ TEMENT OF THE INVENTION
The invention comprises a composition for removing paint, particularly graffiti, from surfaces wherein the composition contains non-toxic and non-irritant ingredients including a synergistic combination of anionic and / or nonionic poly alkoxylated surfactants such as a poly alkoxylated alkyl ethercarboxylic acid, poly alkoxylated alkyl ethercarboxylic ester, poly alkoxylated alkyl ethercarboxylate, poly alkoxylated fatty acid, poly alkylen glycol ester, poly alkoxylated alcohol and a lower poly alkylene glycol alkyl ether having a repeating unit containing 2-9 carbon atoms wherein 5 to 70 % by weight of a polar aprotic solvent and / or a hydrocarbon solvent is present.
The paint removing compositions of the invention do not contain nitrate, sulfate, phoshate impurities or halogenated solvents. It is further noted that the compositions have a neutral pH, are completely soluble in water or completely emulsifiable, although water neutralizes the synergistic effect. The synergism is also diminished as the alkoxy unit of the surfactants and / or the solvents of poly alkylene glycol alkyl ether increases.

The remaining patents are of varying degrees of general interest.
Detailed Description of the Invention
The paint remover composition of the invention has a high flash point > 90 °C, a high boiling point > 150 °C, a very low content of volatile organic compounds ( VOC < 0.5 g/1 ) and a very low vapor pressure ( Vap.p.20"0 < 0.5 mm Hg ). The pH is preferably neutral but can be slightly acid ( pH 5.0 - 7.5 ). The composition is non-toxic, non- irritating, non-flammable and is biodegradable. The solvation activity is believed to proceed as a result of a synergistic combination between poly alkoxylated anionic and / or nonionic surfactants portions and solvents of poly alkylen glycol alkyl ether in which both the surfactant and solvent have similar poly alkoxylated chains.
The solvation activity appears to proceed due to the matched polymeric surfactants initializing an intermolecular reaction with the polymers in the paint. The overlapping electrostatic fields contribute to separation of polymeric chains in the polymeric film former of the paint and possibly to some depolymerization to break cross-links and reduce chain length of the polymer chains as the paint dissolves.
The synergistic effect and solvation activity are not present when water is added to the composition. Water hydrates the surfactants forming sheaths which isolate the surfactants from each other and form the polymer molecules in the film former of the paint. However, water can be used to deactivate the paint remover composition such as after removal of paint or to control an accidental spill.
The overlapping electrostatic fields are enhanced by the addition of nucleophilic-aprotic substances. The viscosity of the composition can be increased by adding a compatible thickener, preferably a hydroxyalkylated cellulose in the range of 0.1 to 5.0 % by weight. These thickeners have been found to not affect the synergistic solvation effect. When the pH is too low, a base such as an amine, suitably a di- or triethanolamine in the amount of 0.1 to 2.0 % by weight can be added to the composition.
The paint remover composition of the invention can be used to remove other materials from substrates such as ink, brushed or sprayed paints, varnishes, resins, enamels, wax, glue etc.
The synergism is demonstrated by a combination of 2 to 20 parts by weight of a poly alkoxylated surfactant ( poly alkoxylated alkyl ethercarboxylic acid, poly alkoxylated alkyl ethercarboxylic ester, poly alkoxylated alkyl ethercarboxylate, poly alkoxylated fatty acid, poly alkylen glycol ester, poly alkoxylated alcohol etc. ) thereof such as those of the formula :
R-[-0-CnH2n-]m-0-R(1)
where R is a hydrocarbon group containing 1-30 carbon atoms such as alkyl, alkylaryl and fatty alkyl, preferably fatty alkyl containing 8-24 carbon atoms, where R(1) is a special group ( see below ), n is 2,3 or 4, m is at least 4 such that the anionic and / or nonionic surfactant is liquid, usually from 2 to 20, preferably from 2 to 10;
R4)-[-0-CnH2n-]m-0-R(5)
where R(4) and R(5) are individually selected from the group consisting of H and alkyl of 1-10 carbon atoms, n is from 2 to 6, preferably from 2 to 4 and m is 2 to 10, preferably from 2 to 4.
poly alkylene glycol alkyl ether R(4)-[-0-CnH2n-]m-0-R(5)
R (4). R (5) = _H; alky, n = 2 ... 6 = 2 ... 10
The synergistic solvent activity decreases as the chain length of alkylene ether group increases and is absent in ethers having a carbon length of 5 or more.
Other optional ingredients are poly alkoxylated alkyl acetates in an amount from 0-30 % by weight, preferably 5-25 % by weight, nucleophilic-aprotic solvents in an amount from 0-70 % by weight, preferably 10-60 % by weight, 0-2 % by weight of a base such as a Group I or Group II metal hydroxide or a polyamine such as di- or triethanolamine and 0-5 % by weight, preferably 1 -3 % by weight, of a thickening agent such as hydroxyalkyl cellulose in which the alkyl contains from 1-6 carbon atoms.
The following formulations provide safe and effective paint removing compositions :
The first optional ingredients are organic solvents selected from nucleophilic-aprotic material and / or a hydrocarbon solvent.
Ingredients for use in the composition of the invention were tested for boiling point [ Kp in °C ], flash point [ Fla.p. in °C ], density [ d2o°c in g/ml ], vapor pressure [ Vap.p in mmHg ], solubility in water and toxicity, results follow :
F = flammable T = toxic Xj = irritant Xn = low irritant
F = flammable T = toxic X, = irritant Xn = low irritant
The following compositions were prepared :
Example No. 1
No. 1 (Classic)
5,0 % CH3(CH2)7CH=CH(CH2)7CH2-[-O-CH2CH2-]9-OCH2COOH oleyl ethercarboxylic acid ( 9 EO ) 19,2 % CH3-[-O-CH2CH2-]3-O-CH3 triethylene glycol dimethyl ether ( triglyme ) 25,0 % CH3-[-O-CH2CH2-]4-O-CH3 tetraethylene glycol dimethyl ether ( tetraglyme ) 25,0 % CH3-[-O-CH2CH2-]n-O-CH3 polyethylene glycol dimethyl ether ( polyglyme ) 10,0 % H-[-O-CH2CH2CH2-]2-O-CH3 dipropylene glycol monomethyl ether 5,0 % 4-methyl-l,3-dioxolan-2-on ( propylene carbonate )
0,3 % triethanolamine ( TEA )
0,5 % hydroxypropyl cellulose
The composition exhibited very strong performance and was found to remove spray paints including those based on polyurethane from surfaces. The composition can be used on stone, concrete, glass and metal surfaces. This composition will also remove paint from other surfaces and can dissolve plastic. Care should be taken to avoid applying this composition to surrounding paint and plastic parts.
Example No. 2
No. 2 (Special)
5.0 % CH3(CH2)7CH=CH(CH2)7CH2-[-O-CH2CH2-]9-OCH2COOH oleyl ethercarboxylic acid ( 9 EO ) 81.7 % H-[-O-CH2CH2CH2-]2-O-CH3 dipropylene glycol monomethyl ether 12.5 % 4-methyl-l,3-dioxolan-2-on ( propylene carbonate )
0.3 % triethanolamine ( TEA )
0.5 % hydroxypropyl cellulose
This composition, though high performance, is not as strong as the composition of Example No. 1. It will remove spray paints from most surfaces and will not affect an underlying film of paint. For example, graffiti can be removed from printed utility boxes, carpets, upholstery etc..
This product must remain on the graffiti or other stain less than 5 minutes, because plastics, the underlying paints and man-made fibres can be attacked if in contact with the composition for a longer period of time.
The compositions of Example No. 1 and No. 2 were varied by substituting poly alkylene glycol alkyl ether of increasing carbon content.
The solvation power of the paint remover composition is presented in the following table :
Paint removal with the composition of the invention is very simple. It will remove most spray paints ( graffiti ) but also ink, brushed or sprayed paints, varnishes, resins, enamels, wax, glue, etc.. The paint remover product of the invention is environmentally sensitive and accomplishes the removal of paint or other substances in a simple, safe procedure.
The paint remover compositions consist of a finely balanced blend of anionic and / or nonionic surfactants with synergistic effects that operates with polymeric organic ether, ester and ketonic compounds. The products do not contain nitrate, sulphate, phosphate salts or other impurities such as halogenated solvents. They have neutral pH, are completely soluble in water or completely emulsifiable, having a high flash point ( Fla.p. > 90 °C ), a high boiling point ( Kp > 150 °C ), a very low content of volatile organic compounds ( VOC < 0.5 g/1 ) and a very low vapor pressure ( Vap.p.20°c < 0.5 mm Hg ), they are non- toxic, non-irritating, non-flammable and are biodegradable.
The paint remover of the invention can be used on nearly all surfaces safely. The composition has a high efficiency for each gallon it is possible to remove paint on approximately 40 yd2, depending on the kind of surfaces ( textures from smooth to porous ) and the constitution of the paint ( age, thickness, quality ). The products of the invention are far superior to all previous paint removal products.
The composition can simply be sprayed or brushed on surfaces that need paint removing. Leave it in place for 2 to 10 minutes, depending on the surfaces and constitutions of the paint ( see above ). After processing, it can be cleaned by rubbing off with a towel, sponge, brush, or preferably by means of a high pressure water sprayer ( 1 ,000 to 2,000 psi ). It is important to wash the residue of the paint remover off with water to deactivate the solvent activity. Old or thick paint may require the process to be repeated two or three times. For thick paints it is helpful to use a wire brush before processing, to rough up the surface so that the paint removal products can penetrate faster. The composition should not be used at temperatures below 35 °F and outside in the rain. It is prudent to pre-tcst the surfaces for possible reactions with the products.
The composition of the invention can also contain minor amounts of optional ingredients suitably as dyes or pigments enhancing substances and preservatives each in an amount effective to provide the desired effect, along with a fragrance. The composition of the invention can also be used to remove fingernail polish. Cosmetic compositions can contain a skin protectant such as glycerine or diglycerol.
It is to be realized that only preferred embodiments of the invention have been described and that numerous substitutions, modifications and alterations are permissible without departing from the spirit and scope of the invention as defined in the following claims.
