Description
DESCRIPTION
Aqueous Floor Polishing Composition Technical Field The present invention relates to an aqueous floor polishing composition excellent in gloss restorability.
In particular, the present invention relates to an aqueous floor polishing composition which is desirable for the application to floor surface of wooden floor material, floor material comprised of synthetic resin, or stone floor made of concrete or marble, especially, for dry maintenance which is carried out as daily maintenance by using a combination of cleaning with an automatic floor cleaning machine and buffing with a high-speed polisher.
Background Art Floor polishing agents have been used for the floor surface of wooden floor material, chemical floor material made of synthetic resin, or stone floor material comprised of concrete or marble for the purpose of keeping the beauties of the floor material and protecting the floor surface. The floor polishing agents generally include oil-type agents using solvents, aqueous agents, emulsion-type agents and the like. For example, Japanese Patent Publication Nos. Sho 47-14019 and Sho 47-15597 disclose floor polishing compositions which use a polyvalent metal compound in a polymer of an ethylenically unsaturated compound. The coating film obtained by applying and drying this floor polishing composition is excellent in durability or travelling, and nowadays, this type of floor polishing composition is dominantly used.
A floor polishing agent containing an aqueous emulsion of polyurethane resin has been developed for the purpose of improving anti-slip properties. See, e.g., Japanese Patent Publication No. Sho 53-22548. In addition, Japanese Patent Application laid-Open No. Sho 61-148273 discloses that in order to improve heel-mark resistance or scuff resistance, the film durability can be enhanced by using a mixture of an aqueous resin with colloidal silica and butoxyethyl phosphate in combination. Furthermore, Japanese Patent Application Laid-Open No. Sho 8-41382 discloses a method for improving film durability. However, in the aforementioned prior art, there is no disclosure of significantly improving gloss restorability by buffing, and hence, the development of new technique has been desired in this field.
The buffing operations in dry maintenance are carried out for restoring the floor surface by plastically deforming or cut-removing small damages on the coating surface caused by walking, etc. and restoring gloss lowered by walking, etc.
In general, the improvement in the gloss restorability by buffing with floor polish may be achieved by adjusting a composition of resin in an acryl-styrene type emulsion which is a main component of a polishing agent, but heel-mark resistance, scuff resistance, etc. are deteriorated. Accordingly, it has been very hard to obtain a floor polishing composition which is excellent in gloss restorability by buffing, and besides, excellent in heel mark resistance and scuff resistance.
Disclosure of Invention The present invention is to provide a novel, aqueous floor polishing composition capable of forming a coat showing excellent gloss restoration by buffing while retaining general properties such as durability required for floor polishing agents.
The inventors found out, as a result of eager investigation and study, that the use of a butadiene type copolymer component in an aqueous floor polishing resin composition will readily afford the evenness of a coat after buffing by means of a high-speed polisher, thereby improving the gloss restoration by buffing.
Thus, according to the present invention, there is provided an aqueous floor polishing composition characterized by containing 5 to 100 parts as solid of a styrene-butadiene type copolymer emulsion based on 100 parts as solid of an acryl-styrene type resin emulsion.
The styrene-butadiene type copolymer emulsion which can be used for the present invention is preferably that obtained by copolymerization of styrene and butadiene. Any type of thus obtained copolymer may be used regardless of molecular weight, molecular structure and preparation method. For the copolymerization of styrene and butadiene aromatic and/or aliphatic monomers such as methyl methacrylate and the like may be incorporated at an arbitrary copolymerization ratio. Copolymerization with unsaturated fatty acid such as acrylic acid and methacrylic acid or dispersion into water using emulsifiers may be conducted for water dispersibility or water solubility. Such butadiene type copolymer latex, including copolymers obtained by emulsion copolymerization of butadiene and a variety of monomers, is widely used for compositions for paper coating or the like. A typical example of such latex is described in Japanese Patent Publication No. 54-6575. The water base floor polishing agent of the present invention can be prepared by adding such butadiene type copolymer latex into acryl-styrene type resin emulsions. It can be also prepared by polymerizing monomers containing butadiene in the presence of acryl-styrene type copolymerization components or polymerizing monomers such as aliphatic unsaturated compounds and styrene in the presence of butadiene type copolymerization components. Concerning the ratio of acryl-styrene type resin to styrene-butadiene type copolymer emulsion, the styrene-butadiene type copolymer emulsion is in the range of 5 to 100 parts, preferably in the range of 5 to 50 parts, with respect to 100 parts of acryl-styrene type resin.
The butadiene in the styrene-butadiene type copolymer emulsion is preferably in the range of 25 to 70 o by weight, and the styrene in the styrene-butadiene type copolymer emulsion is preferably in the range of 0 to 75 % by weight, and more preferably in the range of 30 to 75 % by weight.
An example of the acryl-styrene type resin emulsion which can be preferably used in the present invention is the resin composition disclosed in Japanese Patent Publication No. 44-24409 or the like.
The composition comprises a copolymer of alpha, beta-ethylenic unsaturated carbonic acids and ester derivatives thereof, especially acrylic acid or methacrylic acid and ester derivatives thereof, and aromatic monomers such as styrene. Specifically an ethylenic unsaturated compound is selected from the group consisting of styrene, methylstyrene, acrylic acid, methyl acrylate, ethyl acrylate, propyl acrylate, butyl acrylate, hexyl acrylate, 2-ethylhexyl acrylate, lauryl acrylate, methacrylic acid, methyl methacrylate, ethyl methacrylate, propyl methacrylate, butyl methacrylate, hexyl methacrylate, 2-ethylhexyl methacrylate, vinyl acetate, acrylonitrile, itaconic acid, malefic acid and the like, thereby obtaining the polymer emulsion by a known emulsion polymerization method.
In the present invention, for the purpose of satisfying various characteristics required for the floor polishing agent, various additives can be contained in the aqueous floor polishing composition.
Among the characteristics, an appropriate sliding property can be obtained and its black heel mark resistance and durability are made excellent by adding a wax to the composition. As the wax, it is possible to use an aqueous solution of a natural wax or a synthetic wax dispersed therein which is generally used for floor polishing. Specifically, the natural wax includes carnauba wax, paraffin wax and the like. The synthetic wax includes polyethylene, polypropylene and oxides thereof as well as waxs obtained by polymerizing unsaturated monomers such as ethylene, propylene and the like or monomers selected from the group consisting of a- or ~i-ethylenically unsaturated carboxylic acid, alkyl esters thereof and the like. Though the wax content in the aqueous floor polishing composition of the present invention is optionally determined, 0 to 20 % by weight is preferable.
A crosslinking agent is added to the aqueous floor polishing composition of the present invention to improve the duralibility of an obtained coating film.
The crosslinking used in the present invention includes polyvalent metal salts or polyvalent metal complexes by which a metal crosslinking can be formed.
Specifically, it is possible to use calcium, magnesium, zinc, barium, aluminum, zirconium, nickel, iron, cadmium, strontium, bismuth, beryllium, cobalt, lead, copper, titanium and antimony. In particular, calcium, magnesium, zinc and aluminum are preferable. The ligand for forming the polyvalent metal complexes includes carbonate ion, acetate ion, oxalate ion, malate ion, hydroxyacetate ion, tartrate ion, acrylate ion, lactate ion, octate ion, formate ion, salicylate ion, benzoate ion, gluconate ion, glutamate ion, and glycine, alanine, ammonia, morpholine, ethylenediamine, dimethylaminoethanol, diethyamionethanol, monoethanolamine, diethnolamine, triethanolamine, as well as inorganic acids, organic acids, amino acids, amines and the like which are similar thereto. In particular, zinc ammonium carbonate, calcium ethylenediamine-ammonium carbonate, zinc ammonium acetate, zinc ammonium acrylate, zinc ammonium malate, zirconium ammonium malate, zic ammonium aminoacetate, calcium ammonium alanine and the like are preferable.
In the aqueous floor polishing composition of the invention, by incorporating an alkali-soluble resin, it is possible to improve the leveling property, peelability and glossiness. As the alkali-soluble resin, there can be included styrene-malefic acid copolymer resin, rosin-malefic acid copolymer resin, water-soluble acrylic resin, water-soluble polyester resin, water-soluble epoxy resin, or the like. The content of the alkali-soluble resin in the aqueous floor polish composition of the present invention can arbitrarily be determined.
In the aqueous floor polishing composition of the invention, by incorporating an aqueous polyurethane type resin, it is possible to improve the durability.
As the aqueous polyurethane type resin, there can preferably be used one containing a carboxylic acid and/or carboxylate bonded to a chain of a polyurethane type resin. Such a resin can be obtained by, for example, when producing a polyurethane type resin, adding diol or the like having a carboxylic acid group to diol and di-isocyanate, neutralizing the carboxylic acid group as needed, and effecting polymerization.
The introduction of a carboxylic acid group affords an aqueous polyurethane type resin having water-dispersibility or water-solubility. Further, adding an emulsifying agent can make the resin aqueous as needed.
The aqueous floor polishing composition of the invention may contain an plasticizer or film-forming assistant. As the plasticizer, there are included dibutyl phthalate, dioctyl phthalate, 2-pyrrolidone, octyl diphenyl phosphate, tributoxyethyl phosphate, and the like. As the film-forming assistant, there are preferably used alkylene glycol monoalkyl ether, dialkylene glycol monoalkyl ether, trialkylene glycol monoalkyl ether, and there are specifically included diethylene glycol monobutyl ether, diethylene glycol monoethyl ether, dipropylene glycol monomethyl ether, and the like.
The aqueous floor polishing composition of the invention may contain silica sol. Further, the composition may contain a fluorine type surfactant or a preservative.
The present invention will be described below in great detail by giving Examples and Comparative Example which will illustrate the technical effects of the present composition.
Ten (10) parts of a styrene-butadiene type copolymer latex composed chiefly of styrene/butadiene =
60/40, having Tg of -1°C was added to 100 parts of an acryl-styrene type resin emulsion composed of butyl acrylate/methyl methacrylate/ styrene/methacrylic acid - 32/28/20/20, having Tg of 46°C and an acid value of 130 to prepare an aqueous floor polishing composition 1 of the present invention.
An aqueous floor polishing composition 2 of the present invention was prepared in the same manner as in Example 1 except that the amount of the styrene-butadiene type copolymer latex was changed to 20 parts.
An aqueous floor polishing composition 3 of the present invention was prepared in the same manner as in Example 1 except that the amount of the styrene-butadiene type copolymer latex was changed to 30 parts.
COMPARATIVE EXAMPLE
Only the acryl-styrene type resin emulsion used in Example 1 was used and made an aqueous floor polishing composition 4.
The aqueous floor polishing composition obtained in Example 2 was dried at 60°C for 12 hours to prepare a sample for analysis, which was then analyzed as to the butadiene contained in the composition by using an infrared spectrophotometer (KBr tablet method;
integration for 100 times using 60SX Fourier transform infrared spectrophotometer manufactured by Nicolet).
As a result, absorption peaks were observed in the wavelength regions of 960 to 970 cm-1 (trans 1,4 CH
bending vibration), 900 to 920 cm-1 (R-CH=CH bending vibration) and 1640 cm-1 (C=C stretching vibration) which are the characteristic absorption bands of butadiene copolymer. Further, as a result of another analysis which was carried out by using a thermal decomposition gas chromatograph (HP5890A gas chromatograph manufactured by Hewlett Packard Co., Ltd.; FID detection; high frequency furnace type thermally decomposing apparatus manufactured by Nippon Bunseki Kogyo K.K.; thermal decomposition at 590°C for 5 sec.), the butadiene monomer decomposed was confirmed, so that it was confirmed that butadiene was contained as the monomer component in the aqueous floor polishing composition of the present invention.
The aqueous floor polish compositions 1 - 4 prepared in Examples 1-3 and Comparative Example 1 were used to prepare floor polishing agents. To 100 parts by solid weight of the composition, 10 parts of tributoxyehtyl phosphate (a plasticizer), 25 parts of diethylene glycol monoethyl ether (a filming aid), 0.05 parts of fluorine-based detergent Zonyl FSJ (25%
solid)(a product of Du pont), 6.37 parts of ammonium carbonate zinc aqueous solution (12% solid), 6.25 parts of styrene malefic acid resin SMA-2625A (15$ solid)(a product of ATOCHEM), 18.76 parts of polyethylene wax emulsion Hytec E-4B (40% solid) (a product of Toho Kagaku Inc.), and 0.68 parts of Deltop (a preservative, a product of Takeda Chemical Industries) are added successively.
With each aqueous floor polishing agent thus obtained, gloss restoration by buffing was determined.
The results are shown in Table 1. The determination method is as follows:
1. Glossiness: determined according to JIS K-3920 (Test method for floor polish);
2. Gloss restoration by buffing: Onto a homogeneous vinyl floor tile (a product of TORI Inc., product name:
MATICO S PLAIN No.5626), the sample polishing agent was applied five times, and then the glossiness was measured (a). After that, the gloss was removed by using an automatic floor washing machine J-CRUISE ( a product of Johnson Professional Inc.)((b)), then the tile was buffed twice by using Ultra high speed polisher SPRINT-2000BP(a product of Johnson Professional Inc.) with a green pad (c and d), to determine the gloss restoration by buffing from the glossiness difference before and after buffing.
Table 1 Glossiness Restoration by Buffing Examples Comp. Example Glossiness (a) 5x application 73 72 70 75 (b) before buffing 51 50 52 52 ( c ) after first buffing 65 65 67 58 (d) after second buffing 67 69 70 60 Gloss restoration(%) after 1st buffing 64 68 83 26 before 2nd buffing 73 86 100 35 Gloss restoration(%)=(gloss after buffing - gloss before buffing)/(gloss after 5x application - gloss before buffing) Effect of Invention As shown in Table 1, high rates of gloss restoration are attained by using the composition of the invention. In other words, the use of an aqueous floor polishing composition containing 5 to 100 parts as solid of a styrene-butadiene type copolymer emulsion based on 100 parts as solid of an acryl-styrene type resin emulsion, according to the invention, will afford both high gloss restorability in buffing and high durability that have been long desired as properties for floor polishing agents. The aqueous floor polishing composition of the invention is particularly suitable for 'dry maintenance' that is a daily maintenance work comprised of washing by means of an automatic washer and buffing by means of a high-speed polisher.
