Description

  The present invention relates to US patent application Ser. No. 12 / 422,704 filed Apr. 13, 2009 (currently pending) and U.S. patent application Ser. No. 12 / 239,587 filed Sep. 26, 2008. , And claims priority under the Paris Convention of US Patent Application No. 6 / 072,114 filed on March 28, 2008.

  The present disclosure relates to the field of repair compositions, bonding compositions, surface compositions and coating compositions for surfaces. The present disclosure also relates to methods of making the above surface compositions and methods for their use.

  The surface referred to here includes, but is not limited to, a finished surface and a surface to be finished, and generally includes defects. In many cases, the surface is a painted surface (such as but not limited to a wall) or the surface is an unfinished surface to be painted. For example, walls in a residential structure may include grooves, holes or other defects as a result of daily life and decoration. The above-mentioned grooves, holes and other defects should be repaired to maintain landscape quality. Furthermore, when building a building, the drywall and other materials are joined together by bonding the composition, and defects on the drywall surface are smoothed using such a composition. Such defects can be just the surface, but can harm the integrity of the material if the paint or other finished protective layer is torn.

  Conventionally, such defects are referred to as repair compositions, bonding compositions, surface treatment compositions, or plaster compositions (hereinafter generally referred to as surface treatment compositions), depending on the size and type of the defect. Filled with. The surface treatment composition is applied to the defective areas, dried and then finished as necessary. When repairs are made, the finish is applied as closely as possible to the original surface. The surface treatment composition is generally further trimmed, such as by polishing and priming, before finishing is applied.

  However, conventional surface finish compositions have several drawbacks. Most surface treatment compositions dry to a state that does not closely match the original surface. As a result, when finished, the repaired surface does not match the original finished surface, revealing that part has been repaired. For example, when a surface treatment composition is applied to a painted surface, the repaired surface often has a shiny, glossy appearance. Such gloss can only be removed through further work, but such gloss removal is not always possible with some surface treatment compositions. If the surface of the repair is “flat” in appearance so that it conforms to the original surface, the repaired portion will look more beautiful. Furthermore, when the surface treatment composition is used in a building to condition a finish untreated surface, the portion to which the surface treatment composition is applied can be the portion that is visible after the finish treatment is applied. Furthermore, surface treatment compositions are generally primed prior to painting, otherwise the adhesion between the paint and the repair site will be poor, causing blistering, flushing and other problems. . If no primer is needed, time and effort are saved.

The paint itself causes disposal problems mainly. Household paint is considered a hazardous waste. Disposal of used and unwanted paint is expensive and is typically achieved by the deposition of paint on landfills. Landfill accumulation creates the potential for excess paint to leak into the surrounding area, causing environmental harm. In addition, the possibility that waste paint will not be included properly creates civil and criminal liability and environmental cleanup should be required.

  The proposed regulations in the sale of alkyd paints in the United States can result in a large amount of useless alkyd paints that need to be discarded in the near future. Alkyd paints are oil-based paints where the diluent or solvent is typically (but not necessarily) petroleum spirit and the binder is an alkyd resin. Petroleum spirit is a volatile organic compound (VOC). Once the alkyd paint is applied to the surface, the petroleum spirit evaporates, causing significant VOC contamination. The proposed regulations limit the use of alkyd paints based on VOCs, and this creates the need for an economical and safe way to reuse these paints.

  For the above reasons, for example, it is possible to repair finished surfaces and finish unfinished surfaces such that the appearance of the surface treatment composition is reduced or eliminated compared to prior art surface treatment compositions. Surface treatment compositions are required. Furthermore, excellent methods of reuse and reuse are required for both alkyd paints and other types of paints.

III. Surface Treatment Composition The present disclosure provides a surface treatment composition for repairing a finished surface and repairing an unfinished surface. Embodiments of the composition are those that can be used as a volume agent in a primer to increase viscosity and aid spreading. Such surface treatment compositions are useful for joining and repairing surface defects. The various embodiments of the surface treatment composition disclosed herein have various advantages over the already known surface treatment compositions. Various embodiments of the surface composition have at least the following advantages: dry quickly after application to the surface; do not require a primer prior to painting; can be applied to a wide variety of surfaces; exhibit good adhesion Providing a surface having no visible features (such as, but not limited to, glossy) to identify where the composition has been applied; and providing a method for recycling waste paint Have at least one.

The surface treatment composition of the present disclosure includes a dry paint. In certain embodiments, the dry paint is
It can be granular in nature. The granular dry paint can be obtained from any source. Granular dry paints can be obtained from previously painted surfaces. In an embodiment of the surface treatment composition, the granular dry paint can be obtained by removing the paint from the surface that has been applied so far, and grinding the paint to produce a granular product. In these particular embodiments, the impurities are removed from the dry paint prior to combining the filler and the dry paint. In these particular embodiments, the granular dry paint is further dried after being removed from the previously painted surface by any of the drying methods described herein.

  In some embodiments of the surface treatment composition, the granular dry paint can be obtained by drying and grinding the liquid paint. Liquid paints can be obtained from any source, including overcoats, paints purchased in excess of what is required for the work, paints manufactured in excess of order, and paints stored for longer than their lifetime. Can be. The paint may be an oil-based paint including an acrylic (water-based) paint or an alkyd paint. The alkyd paint has the advantage that it dries quickly and is well ground. The paint can be dried by any suitable method known to those skilled in the art including heating, low pressure, or blowing (alone or in combination). An embodiment of the surface treatment composition is one in which the liquid paint is dried by contact with air at room temperature. In the embodiment of the surface treatment composition, the liquid paint is dried by blowing the paint. Blowing can be accomplished using any suitable fan or blower, including typical portable hair dryers for small batches. Larger fans and blowers can be used as well. The paint can be heated during blowing. Heat is conducted to the paint by conduction (eg, heating a container containing the paint), convection (eg, heating air around the paint, such as in an oven), or heat dissipation. Heat can be conducted to the paint by heating the air that is blown into the paint, for example by using a heated blower. If blowing is used, the air should be blown through the paint at a rate sufficient to promote drying.

  Drying can be accomplished by heating alone or in combination with air blowing as described above. When heat is used to achieve drying, the paint is subjected to any temperature above the freezing point of the paint under the following pressure at which heating occurs. If heating occurs in the presence of diatomic oxygen (or other strong oxidant), then the paint can be dried at a temperature below its flash point. Alkyd paints, for example, typically have a flash point of about 100 ° F. (surface temperature of 200 ° F. due to air movement). As a result, in embodiments of the surface treatment composition where the liquid alkyd paint is dried, drying should occur at a temperature of about 100 ° F. or less. In an embodiment of the surface treatment composition, drying is performed at a concentration lower than the concentration of diatomic oxygen in the atmosphere. In these particular embodiments, the alkyd paint may be dried at a temperature of about 100 ° F. or higher. The safe flash point of a particular alkyd paint below a particular concentration of diatomic oxygen can be measured without undue experimentation by those skilled in the art.

  In general, acrylic paints have a higher flash point than that of alkyd paints. Thus, for embodiments of surface treatment compositions comprising acrylic paints, drying can be treated at higher temperatures. Various embodiments of the surface treatment inhibiting product employ drying temperatures of about 100 to 750 ° F, about 200 to 600 ° F, about 250 to 500 ° F, and about 500 ° F.

  The temperature can be changed during a defined batch. The reduced pressure or blowing employed at the defined temperature achieves faster drying.

Oxygen can be reduced or eliminated from the air around the paint during drying. The pressure can be varied in combination with heating or blowing with pressure alone to achieve drying. A pressure of 1 atmosphere or less accelerates drying at a given temperature. Reduced air pressure also has the effect of reducing the effective oxygen concentration that raises the flash point of the paint. Various aspects of the surface treatment composition can be any, some, or none of the following pressures: vacuum, 0.95 atmospheres (atm), 0.9 atm, 0.8 atm, 0.75 atm,. Drying is also achieved at 7 atm, 0.6 atm, 0.5 atm, 0.4 atm, 0.3 atm, 0.25 atm, 0.2 atm, 0.15 atm and 0.1 atm.

  The dried paint can be pulverized by any suitable method known by those skilled in the art. For example, dry paints are: rotary mill, ball mill, rod mill, mortar and mortar, SAG mill, grain mill, self-pulverizing mill, silica mill, roll grinding, colloid mill, disc mill, edge mill, hammer mill, It can be crushed by any of Willy mills. For small batches, the dried paint can be ground in a home food processor or kitchen mixer.

  In an embodiment of the surface treatment composition, the granular dry paint is mixed with an alkyd / acrylic granular dry paint. Since alkyd paints are generally volatile and have a low flash point, it is advantageous to mix dry acrylic paints and liquid alkyd paints. By doing so, a dry paint can be formed without heating the alkyd paint. Dilution of the alkyd paint may also facilitate safer disposal.

  Such mixed alkyd / acrylic granular dry paint is formed by mixing liquid alkyd paint and granular acrylic paint to form a wet paste, drying the wet paste to obtain a dry paste, and pulverizing the dry paste Can be done. The term “dry paste” refers to a product that is not limited to a substance that retains the properties of the paste (although in some cases a dry paste retains the properties of a paste), but is a product of drying a wet paste. . The granular dry acrylic paint can be produced by any of the methods described herein. In some embodiments of the composition, the volume ratio of the granular dry acrylic paint to the liquid alkyd paint is about 3: 1 or exactly 3: 1. The composition can be successfully formed with up to 95% dry acrylic paint and as low as 5% alkyd paint. The dry paste is then ground using any of the methods described herein to form an alkyd / acrylic granular dry paint.

  In some embodiments of the composition, the composition consists essentially of a sealant and a mixed alkyd / acrylic granular dry paint. The ratio of mixed alkyd / acrylic granular dry paint to sealant can be, for example, 40-80%, 50-70%, 55-65%, 60%, 75%, or approximately any of the foregoing.

  In order to achieve mixing of the components of the wet paste and to facilitate drying, the wet paste can be mixed during drying. Mixing can occur as long as necessary to achieve proper mixing and drying. In some situations this can be accomplished in about 2 minutes. Such mixing can be accomplished without undue experimentation by those skilled in the art.

In some embodiments of the surface treatment composition, the granular dry paint is mixed with a filler after drying without further steps. In an embodiment, the granular dry paint is fractionated based on particle size prior to mixing with the filler. The granular dry paint can be fractionated by any method known to those skilled in the art to ensure consistency in granule size. In the embodiment of the surface treatment composition, fractionation is performed to produce an approximately consistent granular dry powder of the powder. For example, in an embodiment, the paint is first screened with a # 80 sieve, and the remaining fraction of # 80 (“retentate”) is further either a # 20 sieve or a # 25 sieve. Sifted through. The fraction that passed through the # 20 or # 25 sieve (“siftate”) is mixed with a sealant as described herein. In some embodiments, the granular dry paint is screened such that about 90% of the granular dry paint has a particle size of up to about 2.0 mm. Some embodiments have a diameter of about 0.18 to 2.0 mm. Some embodiments have a diameter of about 0.17 to 0.70 mm. In embodiments, the fine granular dry paint, where the fractionation is performed using household flour sieves, has the advantage of being more easily deployed in the surface treatment composition.

  The granular dry paint is mixed with a filler. In various embodiments of the surface treatment composition, the ratio of the granular dry paint to the sealant is: 40-80%, 50-70%, 55-65%, 60% and approximately at least of these values One. For example, one embodiment of the composition is a product (volume: 60% volume ratio) of a 16 fluid ounce sealant mixed with 24 volume ounces of granular dry paint.

  The paint and the sealant can be mixed by any method known to those skilled in the art. Such mixing methods include blending, shaking, mixing, agitation and mixing. Mixing can be performed using any suitable apparatus depending on the scale of the batch to be produced. Suitable equipment include, for example, commercially available paint blenders (such as CEI Flow Master manufactured by ColorEng, Hudson, NH), drill-mounted paint blenders (such as those sold by Vermont American Tools, Lincolnton, NC). , Table top shakers (such as Blair 51000 sold by Blair Equipment, Flint, Michigan), commercial kitchen arm mixers, and household mixers.

  Embodiments of the surface treatment composition can include any sealant. The sealant may be water-based, oil-based, or alkyd-based. In the embodiment of the surface treatment composition, the sealant includes a water-based acrylic sealant. In certain of these embodiments, the filler may further comprise a styrene-acrylic resin. The filler may further include (but is not limited to) titanium dioxide or extender pigment, and may or may not include a dye. In various embodiments of the surface treatment composition, the filler is selected from the following: Texanol (CAS number 25265-77-4), Styrene copolymer (CAS number 25750-06-5), Styrene acrylic copolymer (CAS number 25085-). 34-1) and at least one of formaldehyde. In various embodiments of the surface treatment composition, the filler may comprise at least one of the following: limestone, titanium dioxide, and quartz.
