Description

【0001】
【産業上の利用分野】
本考案は、例えば、多彩色模様を表出させるための塗装に用いられる塗装用ローラーに関するものである。
【0002】
【従来の技術】
本考案者らは、先に、キトサン/酸イオン錯体液に無機系および/または有機系顔料を添加し、同液から着色キトサン膜を形成し、その破砕物を2色以上、塗料中に含ませてなるキトサン含有水性多彩模様塗料組成物を発明し、これを特許出願した(特願2002−112830号)。この塗料組成物を石膏ボードなどにスプレー法により吹き付け塗装しようとすると作業環境問題や作業場所周辺への悪臭流出の問題を招く恐れがあり適当でない。そのため、塗装ローラーを用いる塗装が考えられる。
【0003】
従来の塗装用ローラーは、一端に把手を有する支軸と、支軸に回転自在に設けられたローラー本体とから構成されたものであり、ローラー本体は多孔質発泡体、例えば軟質ポリウレタンフォームで構成されている。
【0004】
【考案が解決しようとする課題】
上記構成の従来の塗装用ローラーを用いて、キトサン含有水性多彩模様塗料組成物を石膏ボード等に塗装しようとすると、上記破砕物が塗料バインダーから分離してしまい、綺麗な塗装面が得られない。
【0005】
本考案は、多彩模様塗料組成物の塗装において、作業環境問題や作業周辺への悪臭流出の問題を招く恐れがなく、しかも、同塗料組成物からなる塗膜において上記破砕物が塗料バインダーから分離するということもなくて、綺麗な塗装面を形成することができる塗装用ローラーを提供することを課題とする。
【0006】
【課題を解決するための手段】
本考案による塗装用ローラーは、少なくとも一端に把手を有する支軸と、支軸に回転自在に設けられたローラー本体と、同本体の周面全体に装着された吸水性織布製の表面材とからなるものである。
【0007】
上記透過性表面材はローラー本体に密着するように伸縮性を有するものであることが好ましい。透過性表面材の素材としては、綿のような天然繊維からなるものが吸水性の点で好ましい。このような透過性表面材としては、例えば、布製の筒状包帯、筒状サポーター等が例示される。
【0008】
ローラー本体の材質は、例えば軟質ポリウレタンフォームのような合成樹脂多孔質発泡体や、ポリエステル等の合成繊維やウール等の繊維であってよい。ポリエステル等の合成繊維やウール等の繊維の場合は、これを芯材に植毛あるいは編み込んでローラーを構成する。
【0009】
ローラー本体を支承する支軸は鋼材製、硬質合成樹脂製等であってよい。支軸の少なくとも一端には屈曲部を経て把手が連設されている。
【0010】
本考案による塗装用ローラーは、どのような種類の塗料に対しても使用できるが、とりわけ、無機系および/または有機系顔料により着色されたキトサン膜の破砕物を2色以上、塗料中に1〜40重量%含有するキトサン含有水性多彩模様塗料組成物に対して使用する場合、上記破砕物が塗料バインダーから分離するということがなくて、綺麗な塗装面を形成することができるので、特に好ましい。無機系および/または有機系顔料により着色されたキトサン膜は、キトサン/酸イオン錯体液に上記顔料を添加し、同液を例えば塗布し塗布層を乾燥して形成したものである。
【0011】
本考案による塗装用ローラーを適用することが好ましい第2の塗料組成物は、キトサン膜により被覆された2種以上の無機系および/または有機系顔料を塗料中に1〜40重量%含有するキトサン含有水性多彩模様塗料組成物である。第2の塗料組成物において、キトサン膜により被覆された2種以上の無機系および/または有機系顔料は、例えば、上記顔料を塩化カルシウム水溶液に添加し、次いでキトサン/酸イオン錯体液を添加することにより形成したものである。第2の塗料組成物において、キトサン膜により被覆された2種以上の無機系および/または有機系顔料は、上記顔料をキトサン/酸イオン錯体液に添加し、次いで塩化カルシウム水溶液を添加することにより形成したものであってもよい。このように、キトサン膜により被覆された2種以上の無機系および/または有機系顔料を得るには、上記顔料とキトサン/酸イオン錯体液に塩化カルシウムを共存させるのが好ましい。
【0012】
本考案による塗装用ローラーを適用することが好ましい塗料組成物は、上記のようなキトサン含有塗料組成物の外、塗料バインダーとしての合成樹脂(アクリル樹脂、酢酸ビニル樹脂、ウレタン樹脂等)に、無機あるいは有機顔料で着色したフィルム状塗膜を乾燥し破砕してなるフレークを多彩模様形成材として含ませてなる多彩模様塗料組成物であってもよい。
【0013】
つぎに、キトサン膜含有水性多彩模様塗料組成物の各成分について、詳しく説明をする。
【0014】
水性塗料用エマルション樹脂;一般に、水性塗料に用いるエマルション樹脂はアクリル樹脂、アクリルウレタン樹脂、アクリル変性シリコーン樹脂、アクリル変性フッ素樹脂である。ただし、アニオン系界面活性剤を用いて乳化されている樹脂は、カチオン性を示すキトサン溶液と反応し凝集を起こすので、使用には不向きである。この際、アニオン系界面活性剤にノニオン系界面活性剤が併用されていれば、特にアニオン系界面活性剤より多く使用されている場合には、上記凝集作用は緩和される。これは反応性乳化剤を使用した系でも同様な結果を示す。キトサン;キトサンは、市販されているものを使用することができ、分子量、粉末の粒径およびキチンの脱アセチル化度の差異が最終塗料へ与える影響は殆どない。得られた顔料皮膜の強さを向上させる点で、より分子量の大きなキトサンを使用する方が望ましい。
【0015】
キトサン/酸イオン錯体膜の合成;用いる酸は、硫酸や燐酸等以外は特に限定されないが、酢酸、塩酸、蟻酸、アクリル酸、乳酸およびリンゴ酸等の無機酸や有機酸が例示的に挙げられる。望ましいのは臭気の少ない乳酸、リンゴ酸等の有機酸の水溶液である。この際、使用する酸の濃度および酸の量には特に制限はないが、キトサンの濃度が高くなるに伴い粘度が上昇し撹拌が困難と なるので、キトサンの添加量は、酸の水溶液100重量部に対し好ましくは1〜10重量部である。
【0016】
キトサン膜の合成;得られたキトサン/酸イオン錯体液の乾燥膜を水酸化ナトリウム水溶液または塩化カルシウム水溶液等のアルカリ金属およびアルカリ土類金属塩の水溶液、またはアンモニアやピリジン等の含窒素化合物の水溶液中に浸漬する。これら各水溶液の濃度は限定されないが、高濃度のものは特に必要なく低濃度の液でよい。膜を液に浸漬し引き上げて乾燥させると、ほぼ無色透明のキトサン膜が得られる。得られたキトサン膜は、シンナーおよびアルコール等の有機溶剤、また水に不溶である。通常、アルカリ性を示す水溶液では、廃水処理の問題があるので、塩化カルシウム水溶液を使用するのが好ましい。
【0017】
多彩模様形成着色体;市販の樹脂分散型着色顔料を水酸化ナトリウムや塩化カルシウム等のアルカリ金属やアルカリ土類金属塩の水溶液に添加すると、着色顔料の表層が被覆化され、一種のゲル化現象を起こす。このゲル化物を低速攪拌により適度に粉砕し濾取し、十分水洗し乾燥後、多彩模様を形成する材料として用いた場合、ローラー塗りまたは刷毛塗りすると被覆顔料が破壊され、2色以上の色が混合され、多彩模様にはならない。これは、表層被覆化された着色顔料の強度が弱く、塗布時の機械的な塗布圧力に耐えられないことが原因と考えられる。このゲル化した着色顔料の液にキトサン/酸イオン錯体液を適量添加したものを攪拌により適度に粉砕し濾取し、十分に水洗し乾燥後、得られたキトサン膜被覆顔料を、先と同様に、多彩模様を形成する材料として用いた結果、ローラー塗りおよび刷毛塗り共に、2色以上の顔料が破壊・混合されることなく、多彩模様となることが認められ、多彩模様塗料を形成する素材となり得る。
【0018】
これらキトサン被覆着色体は塗料に2色以上添加することで、多彩模様を形成するが、その添加量は塗料の塗装作業性を損ねない条件下では特に制限はない。具体的には、塗料100重量部(固形分)に対し0.01〜30重量部であるが、キトサン膜自体の持つ諸機能が発揮され、更に意匠性等を考慮すると、1〜20重量部が好ましい。
【0019】
上記水性塗料組成物は、上記合成方法により得られたキトサン膜を含有させて多彩模様塗料組成物である。これは、建築用仕上塗材の構成成分として、防腐剤、酸化防止剤、体質顔料、粘性調整剤、レベリング剤、消泡剤、分散剤、成膜助剤、湿潤剤、難燃剤、増粘剤等の添加剤を適宜含む。ただし、キトサン膜を完全に溶解させる様な添加剤の使用は好ましくない。また、上記塗料組成物は主に建築用内装材として設計されるが、外壁材に適用する場合には耐候性を向上させる目的で、光安定剤や紫外線吸収剤を必要に応じ、キトサン膜や塗料中に添加することも可能である。
【0020】
この様にして調製された塗料は、本考案による塗装用ローラーを用いたローラー塗装により、新築および改修建物の一般内部、浴室や洗面所等の水周り部に塗布できる。また、一般適用下地としては、外壁部を含めコンクリート、モルタル、石綿スレート板や石膏ボード等の無機質系ボード類、塩化ビニールクロス、壁紙等が例示的に挙げられる。塗装に際しては、下地の状態に適した下処理を行うことが好ましい。
【0021】

[Industrial applications]
The present invention relates to, for example, a coating roller used for coating for displaying a multicolored pattern.
[0002]
[Prior art]
The present inventors first added an inorganic and / or organic pigment to a chitosan / acid ion complex solution, formed a colored chitosan film from the solution, and contained two or more crushed products in the paint. The present inventors have invented a chitosan-containing water-based colorful pattern paint composition and filed a patent application (Japanese Patent Application No. 2002-112830). Spraying the coating composition on a gypsum board or the like by a spray method is not suitable because it may cause a problem of a working environment and a problem of outflow of a bad smell around a working place. Therefore, painting using a painting roller is conceivable.
[0003]
A conventional painting roller is composed of a spindle having a handle at one end and a roller body rotatably provided on the spindle, and the roller body is made of a porous foam, for example, a flexible polyurethane foam. Have been.
[0004]
[Problems to be solved by the invention]
Using the conventional coating roller having the above configuration, when attempting to apply the chitosan-containing aqueous multicolored paint composition to a gypsum board or the like, the crushed material is separated from the paint binder, and a beautiful painted surface cannot be obtained. .
[0005]
The present invention does not cause a problem of a working environment or a problem of outflow of a bad odor around the work in the application of a multi-pattern paint composition, and the above-mentioned crushed material is separated from a paint binder in a paint film composed of the paint composition. An object of the present invention is to provide a coating roller capable of forming a beautiful coated surface without having to do so.
[0006]
[Means for Solving the Problems]
The coating roller according to the present invention includes a support shaft having a handle at at least one end, a roller body rotatably provided on the support shaft, and a surface material made of a water-absorbent woven fabric mounted on the entire peripheral surface of the main body. It consists of
[0007]
It is preferable that the permeable surface material has elasticity so as to be in close contact with the roller body. As a material of the permeable surface material, a material made of natural fibers such as cotton is preferable in terms of water absorption. Examples of such a permeable surface material include, for example, a tubular tubular bandage, a tubular supporter, and the like.
[0008]
The material of the roller body may be, for example, a synthetic resin porous foam such as a flexible polyurethane foam, a synthetic fiber such as polyester, or a fiber such as wool. In the case of a synthetic fiber such as polyester or a fiber such as wool, a roller is formed by planting or knitting the fiber in a core material.
[0009]
The support shaft that supports the roller body may be made of steel, hard synthetic resin, or the like. A handle is connected to at least one end of the support shaft via a bent portion.
[0010]
The coating roller according to the present invention can be used for any kind of coating material. In particular, two or more crushed chitosan films colored with inorganic and / or organic pigments can be used in the coating material. When used for a chitosan-containing water-based colorful pattern coating composition containing up to 40% by weight, the above-mentioned crushed material is not separated from the coating binder, and a beautiful coated surface can be formed. . The chitosan film colored with an inorganic and / or organic pigment is formed by adding the above-mentioned pigment to a chitosan / acid ion complex liquid, applying the liquid, and drying the applied layer.
[0011]
The second coating composition, to which the coating roller according to the present invention is preferably applied, comprises a chitosan containing 1 to 40% by weight of two or more inorganic and / or organic pigments coated with a chitosan film in the coating. It is a water-based multi-color paint composition containing. In the second coating composition, the two or more inorganic and / or organic pigments coated with the chitosan film are, for example, the pigment is added to an aqueous calcium chloride solution, and then the chitosan / acid ion complex liquid is added. It is formed by this. In the second coating composition, the two or more inorganic and / or organic pigments coated with the chitosan film are prepared by adding the pigment to a chitosan / acid ion complex solution and then adding an aqueous calcium chloride solution. It may be formed. As described above, in order to obtain two or more kinds of inorganic and / or organic pigments coated with a chitosan film, it is preferable that calcium chloride coexist in the pigment and the chitosan / acid ion complex solution.
[0012]
The coating composition preferably applied with the coating roller according to the present invention includes, in addition to the above-described chitosan-containing coating composition, a synthetic resin (acrylic resin, vinyl acetate resin, urethane resin, etc.) as a coating binder, and an inorganic resin. Alternatively, it may be a multicolor paint composition in which flakes obtained by drying and crushing a film coating film colored with an organic pigment are included as a multicolor pattern forming material.
[0013]
Next, each component of the aqueous multicolor paint composition containing a chitosan film will be described in detail.
[0014]
Emulsion resin for water-based paint; In general, the emulsion resin used for the water-based paint is an acrylic resin, an acrylic urethane resin, an acrylic-modified silicone resin, or an acrylic-modified fluororesin. However, a resin emulsified using an anionic surfactant is not suitable for use because it reacts with a chitosan solution having a cationic property to cause aggregation. At this time, if the nonionic surfactant is used in combination with the anionic surfactant, the above-mentioned aggregating action is alleviated, particularly when the nonionic surfactant is used more than the anionic surfactant. This shows a similar result in a system using a reactive emulsifier. Chitosan: Commercially available chitosan can be used, and the difference in molecular weight, powder particle size and degree of deacetylation of chitin has almost no effect on the final paint. From the viewpoint of improving the strength of the obtained pigment film, it is preferable to use chitosan having a larger molecular weight.
[0015]
Synthesis of Chitosan / Acid Ion Complex Membrane; The acid used is not particularly limited, except for sulfuric acid, phosphoric acid and the like, and examples thereof include inorganic acids and organic acids such as acetic acid, hydrochloric acid, formic acid, acrylic acid, lactic acid and malic acid. . Desirable are aqueous solutions of organic acids such as lactic acid and malic acid having low odor. At this time, the concentration of the acid and the amount of the acid to be used are not particularly limited. However, as the concentration of the chitosan increases, the viscosity increases and stirring becomes difficult. The amount is preferably 1 to 10 parts by weight based on parts.
[0016]
Synthesis of a chitosan film; drying the obtained dried film of the chitosan / acid ion complex solution with an aqueous solution of an alkali metal or alkaline earth metal salt such as an aqueous solution of sodium hydroxide or calcium chloride, or an aqueous solution of a nitrogen-containing compound such as ammonia or pyridine Soak in. The concentration of each of these aqueous solutions is not limited, but those having a high concentration are not particularly required and may be low concentration solutions. When the film is immersed in the liquid, pulled up and dried, an almost colorless and transparent chitosan film is obtained. The obtained chitosan film is insoluble in organic solvents such as thinner and alcohol, and in water. Usually, an aqueous solution showing alkalinity has a problem of wastewater treatment, and therefore, it is preferable to use an aqueous solution of calcium chloride.
[0017]
Multicolored colored pigments: When a commercially available resin-dispersed colored pigment is added to an aqueous solution of an alkali metal or alkaline earth metal salt such as sodium hydroxide or calcium chloride, the surface layer of the colored pigment is coated and a kind of gelation phenomenon Cause When the gelled product is pulverized appropriately by low-speed stirring, collected by filtration, sufficiently washed with water and dried, and used as a material for forming a colorful pattern, when coated with a roller or brush, the coated pigment is destroyed, and two or more colors are colored. It is mixed and does not become a colorful pattern. This is considered to be due to the fact that the strength of the color pigment coated on the surface layer is weak and cannot withstand the mechanical application pressure at the time of application. An appropriate amount of a chitosan / acid ion complex solution was added to the gelled color pigment solution, and the mixture was pulverized appropriately by stirring, filtered, sufficiently washed with water and dried, and the obtained chitosan film-coated pigment was treated in the same manner as above. In addition, as a result of using as a material for forming a multicolored pattern, it is recognized that pigments of two or more colors are formed into a multicolored pattern in both roller coating and brush coating without destruction and mixing of two or more colors. Can be
[0018]
These chitosan-coated colored bodies form a colorful pattern by adding two or more colors to the coating material, but the amount of addition is not particularly limited under conditions that do not impair the coating workability of the coating material. Specifically, the amount is 0.01 to 30 parts by weight with respect to 100 parts by weight (solid content) of the coating material, but 1 to 20 parts by weight when various functions of the chitosan film itself are exhibited and further considering designability and the like. Is preferred.
[0019]
The water-based paint composition is a multicolor paint composition containing the chitosan film obtained by the above-mentioned synthesis method. It consists of preservatives, antioxidants, extenders, viscosity modifiers, leveling agents, defoamers, dispersants, film-forming aids, wetting agents, flame retardants, thickeners It contains additives such as agents as needed. However, it is not preferable to use an additive that completely dissolves the chitosan film. In addition, the above-mentioned coating composition is mainly designed as an interior material for a building, but when it is applied to an exterior wall material, a light stabilizer or an ultraviolet absorber is optionally used for the purpose of improving weather resistance. It is also possible to add it to the paint.
[0020]
The paint prepared in this manner can be applied to the general interior of new and renovated buildings, and water-related parts such as bathrooms and washrooms, by roller coating using the coating roller according to the present invention. In addition, examples of the general application base include concrete, mortar, inorganic boards such as asbestos slate board and gypsum board, vinyl chloride cloth, wallpaper and the like, including the outer wall. When painting, it is preferable to perform a preparation treatment suitable for the state of the base.
[0021]

Reference Example 1 (Synthesis of colored chitosan film)
180 g of distilled water and 10 g of lactic acid were placed in a 300 ml plastic beaker and mixed with a stirrer at room temperature. 10 g of commercially available chitosan powder (manufactured by Koyo Chemical Co., Ltd., SK-50) was gradually added to the mixture, and the mixture was stirred for 90 minutes to obtain a pale yellow transparent viscous liquid. To 200 g of the liquid, 2 g of a tea pigment (for example, Ciba Specialty Chemicals, Unisperse-SRED Oxide RS) was added, and the mixture was further stirred for 10 minutes. The obtained liquid was flatly applied with a metal spatula to a glass plate having spacers of about 0.8 mm attached to both ends and dried at room temperature for 16 hours and then in a 40 ° C constant temperature bath for 8 hours. About 11 g of a colored chitosan / lactic acid complex film was obtained. This film was immersed in a 10% calcium chloride aqueous solution, pulled up, washed with water several times, and then dried in a constant temperature bath at 40 ° C. for 16 hours to obtain a red-rusted chitosan film. Similarly, chitosan films were obtained for primary colors such as yellow, blue, and green, and for colors formed by mixing these arbitrarily. This chitosan film was finely cut into scales having a size of about 2 mm or less.

Reference Example 2 (Synthesis of colored chitosan film)
180 g of distilled water and 10 g of lactic acid were placed in a 300 ml plastic beaker and mixed with a stirrer at room temperature. 10 g of commercially available chitosan powder (manufactured by Koyo Chemical Co., Ltd., SK-50) was gradually added to the mixture, and the mixture was stirred for 90 minutes to obtain a pale yellow transparent viscous liquid. To 200 g of this liquid, 3 g of an ocher pigment (for example, Ciba Specialty Chemicals, Unisperse-SYELLOW OXIDE MS), 5 g of commercially available titanium dioxide (Tyoxide), and a dispersing wetting agent (San Nopco, SN-2020) 2 g was added and stirred for another 20 minutes. The obtained liquid was flatly applied with a metal spatula to a glass plate having spacers of about 0.8 mm attached to both ends, and dried at room temperature for 16 hours and then in a 40 ° C constant temperature bath for 8 hours. About 14 g of a yellow chitosan / lactic acid complex film was obtained. This film was immersed in a 10% calcium chloride aqueous solution, pulled up, washed with water several times, and then dried in a constant temperature bath at 40 ° C. for 16 hours to obtain a cream-colored chitosan film. Similarly, a chitosan film was obtained for a color formed by arbitrarily mixing colors such as blue, green, black, and brown. This chitosan film was finely cut into scales having a size of about 2 mm or less.

Reference Example 3 (Synthesis of colored body coated with chitosan film)
5 g of commercially available inorganic and organic pigments (including surfactant-dispersed type and resin-dispersed type, illustratively Ciba Specialty Chemicals, Unisperse-S, YELLOW OXIDE MS) were poured into 20 g of a 20% calcium chloride aqueous solution. After low-speed stirring (200 to 400 rpm) for about 10 minutes with a disperser, 20 g of a chitosan / lactic acid complex solution prepared in the same manner as in Reference Example 1 was added, and the mixture was further stirred for 10 minutes. After appropriately pulverizing the coated pigment in this manner, the collected pigment was collected by filtration, sufficiently washed with water, and dried to synthesize a colored crushed ozone-colored chitosan film. Separately, 2 parts by weight of titanium dioxide was added to the same system to prepare a light cream-based colored crushed product. Similarly, a colored crushed material coated with a chitosan film having a color formed by arbitrarily mixing colors such as blue, green, brown, black, and white was synthesized. The obtained colored body coated with a chitosan film was a powder having a particle size of 1 mm or less.
