Description
"COMPOSITION OF POLYURETHANE RESISTANT TO DAFlO AND WEAR"
FIELD OF THE INVENTION
This invention relates to polyurethane compositions and, in particular, to oil-modified urethane coating compositions, dispersed in water, having improved resistance to usual wear and rubbing.
BACKGROUND OF THE INVENTION
Those versed in the coatings industry generally know that polyurethane coatings exhibit excellent abrasion resistance, excellent flexibility, resistance to chemicals and
-...durability. These coatings have found important utility for coating hard surfaces, such as hardwood floors that require highly durable coatings that resist the usual wear and tear. The conventional oil-modified urethanes are prepared in organic solvents and applied as clear or pigmented finishes. Once it is applied, the solvent evaporates and the film is cured by oxidation in air of the oil portion _e? polymer. Urethanes carried in conventional solvent have provided high performance floor coverings for many years, but due to government regulations about volatile organic compounds (VOCs) they are now being restricted in certain locations, although versions of these led coatings are known. in solvent, which have a high content of solids and less contaminants, typically there is a compromise between performance, particularly dry regime and hardness. An alternative is to use polyurethanes dispersible in water, carried in water. Applications for this type of "/" include final coatings for wood and vinyl flooring, vinyl upholstery, plastics, base paints and sizing for the automotive industry, leather finishes, Finishes for fiberglass, printing inks and adhesives Water-based urethane coatings are particularly attractive as coatings or varnishes for wood floors, due to their abrasion resistance, fast air drying, low. "* Contained volatile organic (VOC), lack of flammability and ease of cleaning with water. Generally, water-dispersible polyurethanes can be prepared by first reacting polyalcohols and a dihydroxycarboxylic acid with an excess of diisocyanate to form an isocyanate-terminated prepolymer. Said prepolymer is then dispersible in water by neutralization of the acid group with ammonia or tertiary amine to form the corresponding salt group. An alternative jib is to replace the dihydroxycarboxylic acid moiety with a tertiary dihydroxy amine which would be neutralized with an acid such as hydrochloric acid, acetic acid or the like. These polymers are mostly linear, since highly entangled polymers form gels that are not suitable for coating applications. For example, U.S. Patent No. 4,277,380 to Williams and co-inventors, proposes that aqueous polyurethane dispersions can be prepared by reacting an unsaturated ethylenically fatty acid ester, a fatty acid, a semi-dryer, and a urethane prepolymer. terminated with isocyanate of a hydrocarbon diisocyanate and a dihydroxyalkanoic acid. This functional polymer of acid can then be neutralized with ammonia or amines, preferably tertiary amines, and can be dispersed in water. Coating compositions of this type have deficiencies in that they are brittle and do not have the storage stability for a long time necessary for a commercially available lacquer US Patent Nos. 4,066,591 and US Pat.
4,147,679, by Scriven and co-inventors, proposes that polyurethane-polyurea dispersions can be prepared from polyurethane prepolyners containing ethylenic unsaturation, which are extended chain with diamines. These dispersions do not provide adequate performance, particularly with respect to the resistance to conventional wear and rubbing, for such applications as wood floor covering. In general, linear polyurethane dispersions do not provide all the desired key aspects in a floor finish, for example, the usual wear resistance and rubbing. Due to the cost of these polyurethane dispersions, suppliers of the floor finishing industry add acrylic emulsions to reduce the cost. This modification results in floor finishes with -sistance to impact much more deficient. Poly functional aziridines can crosslink these polymers, which significantly improves these properties; However, aziridines can cause serious risks for the health. Carbodiimides have been recommended as crosslinking agents for anionic polyurethane dispersions, but have been shown to be significantly less effective. Thus, there is a need for a dispersion ^ oil-modified polyurethane, stable to storage, which produces rapid drying in air, high purity, good resistance to usual wear, rubbing, abrasion and which produces coatings resistant to stains. and the chemical substances.
BRIEF DESCRIPTION OF THE INVENTION
It is an object of the present invention to provide a "stable polyurethane coating apposition having improved resistance to usual wear and rubbing." It is another object of the present invention to provide a stable composition of polyurethane that can be dried in air, which has high hardness and is resistant to abrasions, chemicals and stains These and other objects, aspects and advantages are obtained by the polyurethane composition of the present invention The polyurethane composition is a modified ethane polymer with oil, dispersible in water The urethane polymer comprises a polymer having isocyanate groups, acid or amine salt forming groups and ethylenic unsaturation, and an active hydrogen-containing compound having active hydrogen functionality of two or more; where a portion of the prepolymer has an extended chain with a compound containing active hydrogen that has e active hydrogen functionality of four or more. In another embodiment, the present invention provides a coating composition resistant to normal wear and rubbing. The coating composition comprises a urethane composition dispersed in water and a promoter that promotes entanglement by air oxidation of the ethylenically unsaturated portion of the urethane composition. The urethane composition comprises a prepolymer having isocyanate groups, acid or amine salt-binding groups and ethylenic unsaturation and a hydrogen-containing compound having active hydrogen functionality of two or more; wherein a portion of the prepolymer has its extended chain with a compound containing active hydrogen, having an active hydrogen functionality of four or more. In another embodiment, the present invention provides a method for forming an oil-modified urethane polymer, dispersible in water, resistant to usual wear and rubbing. The method comprises the steps of forming a prepolymer having isocyanate groups, acid-forming or amine-forming groups, and ethylenic unsaturation; neutralizing the acid or amine salt of the prepolymer formed in the preceding step; dispersing the neutralized prepolymer in an aqueous medium and extending the chain of the dispersed prepolymer with an active hydrogen-containing compound, having an active hydrogen functionality, conditional upon a portion of the chain extension being carried out with a compound which contains active hydrogen having an active hydrogen identity of four or more.
DETAILED DESCRIPTION OF THE INVENTION
As summarized above, the present invention provides an oil-modified, water-dispersible urethane polymer. The urethane polymer comprises a prepolymer having isocyanate groups, acid or amine salt-forming groups and ethylenic unsaturation; and a tax that contains active hydrogen, which has an active hydrogen functionality of two or more. A portion of the prepolymer has the chain extended with an active hydrogen-containing compound having an active hydrogen functionality of four or more.

- The ethylenic unsaturation in the prepolymer is introduced by ester polyols prepared by reaction of an aromatic or aliphatic polyol containing at least two hydroxyl groups per molecule and a fatty acid, characterized in that a portion thereof is an unsaturated fatty acid. Fatty acids are sometimes referred to as "drying" or "drying" agents, particularly when they are in the form of an ester. An exemplary reaction is to partially sterilize a polyol with a saturated fatty acid. Suitable polyols include diols, triols and higher alcohols of low molecular weight. Specific polyols include ethylene glycol, propylene glycol ,. 1,3-propanediol, 1,3-butylene glycol, 1,4-butanediol, bisphenol A, glycerin, trimethylolpropane, pentaerythritol, neopentyl glycol and cyclohexanedimethanol.

A color stabilizer, such as trisnonyl phenyl phosphite can also be added. Other polyols may optionally be included. Examples of other polyols include polycarbonate, polyester, polyether and acrylic polyols. The term "active hydrogen-containing compound" refers to a compound having hydrogens which, due to its position in the molecule, exhibits activity according to the Zerewitinoff test. Active hydrogens include hydrogen atoms attached to oxygen, nitrogen or sulfur and, therefore, useful compounds will include those having at least two of those groups (in any combination) -OH, -SH,
NH I
and -NH2. The portions connected to each group can be aliphatic, aromatic, cycloaliphatic or of a mixed type that does not include carbonyl, phosphonyl or sulfonyl bonds, as described in US Patent No. 4,147,679 to Scriven and co-inventors. Examples of such compounds include amines including polyamines, indole alcohols, mercapto- and alcohol-terminated derivatives, which include polyols which are preferred to the reaction facility they exhibit with the polyisocyanates. Amines generally do not give side reactions, providing higher yields of urethane (or urea) product, no by-products, and the products are hydrolytically stable.Also with respect to polyols there is a wide variety of materials available that can be selected for In addition, the polyols have desired reaction rates with the polyisocyanates, both saturated and unsaturated active hydrogen containing taxes can be used, but saturated materials are preferred because of the superior coating properties. which can be used in the preparation of the urethanes of the invention can be or primary or secondary diamines, wherein the radicals attached to the nitrogen atoms can be aliphatic, alicyclic, aromatic, aliphatic substituted with aromatic, substituted aromatics, "* t > aliphatic or heterocyclic, saturated or unsaturated. Examples of suitable aliphatic and alicyclic diamines are: ethylendiarnine, 1,2-α-pyrrolidiarnine, 1,8-mentanediarin, isophoronediamine, propane-2, 2-cyclohexylamine, ethane-bis- (-cyclohexyllanine), 1,6-diarninohexane, hydrazine, and
CH3 H2 N (CH2 -CH-0) x CH2 -CH NH2 I CH3 ^ *? where x = 1 to 10. The aromatic diamines such as phenylenedianes and toluenediamines can be used. Examples of the mentioned amines are: o-phenylenediamine and p-tolylendia ina. The N-alkyl and N-aryl derivatives of the above amines can be used, such as, for example, N, '-dime i1-o-phenylenediamine, N, N'-di-p-tolyl-m-phenylenediarin and p-aminodiphenylamine. The extension of the prepolymer to obtain polymers / high molecular weight is achieved by the reaction of the isocyanate-terminated prepolymer, dispersed in water, neutralized, with an active hydrogen-containing compound, having active hydrogen functionality of two or more. Typically this is provided by a diamine or a triarnine. Suitable dianins include: ethylenediamine, 1,2- and 1,3-diarninopropane, 1,6-diaminohexane, 1,3-diamino-2,2-dirnethylpropane, isophoronodianine, 1,3- and 1,4,4-diarninohexane, i, '-diarninodicyclohexyl ethane, 4,4'-diamino-3,3' -dirnetyldicyclohexyl-methane, 1, -bis (2-aminopro-2-yl) -cyclohexane, 3,3'-dimethyl-4,4'- diaminodicyclohexyl-methane and mixtures of these diamines. Suitable triamines include diethylenetriarnine and dipropylenetriarnine. In order to obtain the desired resistance to usual wear and rubbing, a portion of the prepolymer must have the chain extended with an active hydrogen-containing compound having an active hydrogen functionality of four or more.
typically, at least 1 to 100%, preferably more than about 10% and better still more than about 25% of the prepolymer is extended with an active hydrogen-containing compound, having active hydrogen functionality of four or more. Examples of compounds containing active hydrogen, which have functionality of four or more include triethylene tetramine, tripropylene tetra and tetraethylenepentane ina. Generally the prepolymer is prepared in the presence, 3? N solvent for the reactants and the prepolymer product. Usually the solvents are organic and can comprise essentially carbon and hydrogen, with or without other elements, such as oxygen or nitrogen. The solvent used is essentially inert to the reaction and, thus, must not contain active hydrogen, as determined by the Zerewitinoff test. Solvents which may be employed include strongly polar solvents, such as methylformamide, esters, ethers, ketoesters, ketones, for example, methyl ethyl ketone and acetone, ether glycol esters, chlorinated hydrocarbons, aliphatic and alicyclic hydrocarbon pyrrolidones, for example, N-Rethyl-pyrrolidones, hydrogenated furnaces, aromatic hydrocarbons and the like, and mixtures thereof. The amount of solvent used to prepare the prepolymer can vary widely and should be sufficient to provide a prepolymer solution having a sufficiently low viscosity to facilitate the preparation of the polymer used in this invention. It is convenient to minimize the amount of solvent to minimize VOCs. For example, the solids content of the prepolymer solution may be about 30 to 100% by weight, preferably about 60 to 100% by weight, approximately. The prepolymer formation can be carried out by mixing the diisocyanate and other reagents in any suitable manner. To facilitate the reaction, about 0.005 to 1000% by weight of the reactants such as a conventional urethane catalyst can be added. These catalysts are exemplified by catalytically active compounds of bismuth, piorne, tin, titanium, iron, antimony, uranium, cadmium, cobalt, thorium, aluminum, mercury, zinc, nickel, vanadium, cerium, as well as magnesium oxide, barium oxide , tertiary amines, pyrones and lactams, the preferred catalyst being dibutyltin dilaurate. The modification reaction with oil introduces
-% = > unsaturated fatty acid within the structure of the polymer. The urethane polymers modified with oil, prepared according to this invention, have sufficient acid values for their salt form to be dispersible in the aqueous medium, and said values can frequently be from 10 to 50, on a non-volatile basis. The solids content of the solutions, for example, can be from about 30 to 100% by weight, preferably from 60 to 100% by weight, before the formation of the salt and the dispersion in the water.
The oil-modified urethane polymers of this invention are advantageously employed as aqueous coating compositions, ie, the prepolymers are dispersed in an aqueous medium, such as water. The chain of the dispersed prepolymer is then extended with an active hydrogen-containing compound having an active hydrogen functionality conditional on a portion of the chain extension being carried out with an active hydrogen-containing compound having a hydrogen functionality Four or more. Frequently, the aqueous compositions have a relatively neutral pH, for example, from 6 to 11, preferably from 6.5 to 9.9 approximately. It should be noted that the neutralization of the acid or the amine salt of the prepolymer and the chain extension can occur substantially simultaneously. The urethane composition includes a promoter for promoting the entanglement by oxidation with air of the unsaturated ethylenically unsaturated polymer of the urethane polymer, after application. Suitable promoters include cobalt, calcium, manganese or zirconium neodecanoate; 1,10-phenanthroline and 2,2-bipyridyl. The composition may contain other ingredients for the coating compositions, in order to modify the properties of the resulting oil-modified urethane, such as plasticizers, pigments, colorants, dyes, surfactants, thickeners, heat stabilizers, anti-caking agents, anti-aging agents -provisioning, fillers, sedimentation inhibitors, ultraviolet light absorbers and the like. The additives, such as promoters, heat stabilizers, ultraviolet light absorbers, etc., can be intimately dispersed in the reaction mixture and apparently become an integral part of the urethane polymer. Alternatively, the additive may be introduced after the urethane polymer has been formed, in which case the additive may be incorporated onto the surface of the polymer may be dispersed in the aqueous medium. The urethane coating composition has improved properties of resistance to usual wear and rubbing and is air-dried, has high hardness and is resistant to abrasions, chemicals and stains.
