Description

【0001】
【発明の属する技術分野】本発明は、建築物の内外装の部材間やジョイント部の目地に充填し、風雨の侵入を防止するシーリング材、種々部材間の接着に用いる接着剤、塗膜防水材などに使用される1成分の湿気硬化性組成物の包装缶に関する。
【0002】
さらに詳しくは、長期間の貯蔵後においても、製品安定性、施工性に優れ、1成分形シーリング材組成物の充填包装缶に関する。
【0003】
【従来の技術、発明が解決しようとする課題】一成分湿気硬化性組成物は空気中の水分と反応し、高分子化、三次元化し硬化することで、所望の接着強度、各種物性を発揮し、様々な用途に適用される。
その包装容器は、硬化を抑制するために、完全に外気と遮断する必要がある。
【0004】
一般に使用される1成分形組成物の包装形態としては、防湿カートリッジ、防湿フィルムパック、防湿フィルムソーセージ、缶蓋を密閉構造とした金属缶などが挙げられる。
【0005】
しかしながら、防湿カートリッジ、防湿フィルムパック、防湿フィルムソーセージ等の包装は、その強度の問題で、大容量の包装単位には適用できない。しかし、実際の建築現場などで多量に使用される材料に関しては、大容量の包装単位であることが好ましい。
【0006】
そのため、大容量の包装単位に対応可能な金属缶が使用される。しかし、金属缶は、防湿カートリッジ、防湿フィルムパック、防湿フィルムソーセージ等の包装に比べ、完全密閉することが困難であり、1成分形組成物が一部硬化してしまうということが起りやすい。その現象を防止するために、缶構造を強化したり、缶蓋のサイズを小さくしたりして、密閉性を上げることが行われているが、その場合、使用時の作業性や、使用後の缶の処理、缶自体の価格、充填の手間などの問題点が発生する。
【0007】
缶内の1成分型組成物の表面に防湿フィルムを被覆する方法、缶内空隙部に吸湿材を入れる方法、空隙部に不活性ガスを封入する方法等種々試みられているが、現時点で完全なものはない。
【0008】
特に、施工時の作業性を確保するため、缶蓋部の面積を大きくした場合、完全な密閉構造を確保するのは不可能であると考えられている。
防湿フィルムで1成分組成物の表面を被覆した場合、内部は問題なく使用できても、防湿フィルムと缶壁の間で硬化が進み、作業上の支障になる。
【0009】
缶内空隙部に吸湿材を入れる方法、空隙部に不活性ガスを封入する方法である程度硬化反応は防げるが、長期の温度差による缶内圧力の変動のため、外気中の僅かな水分が侵入するため、長期にわたって硬化を防ぐことはできない。
【0010】
特に、目地等に充填するために使用されるシーリング材として用いた場合、チキソトロピック性が高い設計になっているため、内部から材料を取り出すためにヘラ等で掻き取らねばならない。その場合、缶壁等に硬化物が発生した場合、著しく作業性が損なわれるという問題がある。
【0011】
【課題を解決するための手段】
そこで、鋭意検討の結果、金属缶の包装において、防湿フィルムで表面を被覆した後、空隙部に特定の硬化性組成物を封入することにより内部の硬化を抑えられることを見出し本発明に至った。
【0012】
つまり、表面に防湿フィルムで被覆した後、防湿フィルムと缶壁との空隙部に特定の材料を封入することで、その材料が硬化し内部の硬化を防止しかつ防湿フィルムを除去する際、缶壁からはく離し、防湿フィルムとともに取り出せ缶壁の硬化物が残らないことを見出したのである。
【0013】
すなわち、本発明は、1成分形湿気硬化性組成物を充填し、表面に防湿フィルムを被覆したのち、蓋をして密閉する包装において、防湿フィルムと缶壁との空隙部に反応性珪素基を有する飽和炭化水素系重合体を主成分として含有する硬化性組成物を充填し硬化させることを特徴とする1成分形湿気硬化性組成物の充填包装缶に関する。
【0014】
【発明の実施の形態】
本発明における1成分形湿気硬化組成物はウレタン系、変成シリコーン系、変成シリコーン−エポキシ系等任意に選択できるが、湿気硬化性のほかに加熱による内部の粘度上昇があまり起らない変成シリコーン系の組成物においてはより顕著な効果が得られる。
【0015】
本発明における包装缶としては通常のブリキ缶のごとき透湿性のないものもしくは、非常に少ないものの中から任意に選択できる。缶は缶フタ等にパッキンを施す等でよい。
【0016】
防湿フィルムとしては、湿分の透過がない、もしくは、非常に少ないものであればよく、各種プラスチックフィルム、2種以上のフィルムをラミネートした複合フィルム、金属蒸着フィルム等の中から任意に選択できる。透湿度の低さ、ハンドリングの容易さなどから考えると、熱可塑プラスチックフィルム/アルミミウムフィルムなどと2種以上のフィルムをラミネートしたアルミ複合フィルムが好ましい。
【0017】
本発明において、防湿フィルムと缶壁との空隙部に封入する反応性珪素基を有する飽和炭化水素系重合体を主成分として含有する硬化性組成物とは、反応性珪素基を有する飽和炭化水素系重合体と必要に応じて可塑剤、充填剤、溶剤、揺変性付与剤、紫外線吸収剤酸化防止材、シラノール縮合触媒、硬化促進剤、硬化遅延剤、接着付与剤、脱水剤、その他添加剤等を使用できる。
【0018】

【0019】
1成分形シーリング材組成物としては、空気中の水分と反応し、硬化するものであればよく、反応性珪素基を持った有機重合体を主成分とした変成シリコーン系組成物、ウレタンプレポリマーを主成分としたポリウレタン系組成物、主鎖にSS結合をもつポリサルファイド重合体を主成分とするポリサルファイド系組成物等が挙げられる。この中で、水分遮断状態での安定性のすぐれた変成シリコーン系組成物が好ましい。
【0020】
変成シリコーン系組成物は、反応性珪素基を持った有機重合体を主成分とし、必要に応じて可塑剤、充填剤、溶剤、揺変性付与剤、紫外線吸収剤酸化防止材、シラノール縮合触媒、硬化促進剤、硬化遅延剤、接着付与剤、脱水剤、その他添加剤等を使用できる。
【0021】
主成分である反応性珪素基を持つ有機重合体とは、シラノール縮合反応により架橋しうる有機重合体で、縮合によりシロキサン結合を生成して、樹脂状、又はゴム状に変わる有機重合体を指す。
【0022】
有機重合体の例としては、反応性珪素基をもつポリアルキレンオキシドが挙げられる。反応性珪素基をもつポリアルキレンオキシドは、室温で空気中の湿度により硬化し、硬化物は優れた柔軟性、伸び特性、透明性、水密性を有するため、シーリング材、接着剤に最適であるが、これに限定されるものではない。反応性珪素基をもつポリアルキレンオキシドの具体例としては、MSポリマー(鐘淵化学工業株式会社製)、エクセスター(旭硝子製)等があげられる。
【0023】

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing material for filling in joints between interior and exterior members of a building and joints to prevent the penetration of wind and rain, an adhesive used for bonding various members, and a waterproof coating film. The present invention relates to a packaging can of a one-component moisture-curable composition used for materials and the like.
[0002]
More specifically, the present invention relates to a filled packaging can of a one-component sealing material composition having excellent product stability and workability even after long-term storage.
[0003]
2. Description of the Related Art A one-component moisture-curable composition exhibits desired adhesive strength and various physical properties by reacting with moisture in the air, polymerizing, three-dimensionally and curing. And it is applied to various uses.
The packaging container needs to be completely shielded from the outside air in order to suppress curing.
[0004]
Examples of the packaging form of the generally used one-component composition include a moisture-proof cartridge, a moisture-proof film pack, a moisture-proof film sausage, and a metal can having a closed can lid.
[0005]
However, packaging such as a moisture-proof cartridge, a moisture-proof film pack, and a moisture-proof film sausage cannot be applied to a large-capacity packaging unit due to its strength. However, for materials that are used in large quantities at actual construction sites, etc., it is preferable that the packaging units have a large capacity.
[0006]
Therefore, a metal can that can handle a large-capacity packaging unit is used. However, it is difficult to completely seal a metal can compared to packaging such as a moisture-proof cartridge, a moisture-proof film pack, and a moisture-proof film sausage, and it is easy for the one-component composition to partially cure. In order to prevent this phenomenon, the can structure has been strengthened and the size of the can lid has been reduced to improve the airtightness. Problems such as the processing of cans, the price of the cans themselves, and the time required for filling.
[0007]
Various attempts have been made, such as a method of coating the surface of the one-component composition in a can with a moisture-proof film, a method of putting a hygroscopic material in a void in the can, and a method of sealing an inert gas in the void. There is nothing.
[0008]
In particular, when the area of the can lid portion is increased in order to ensure workability during construction, it is considered impossible to secure a completely closed structure.
When the surface of the one-component composition is covered with the moisture-proof film, even if the inside can be used without any problem, the curing proceeds between the moisture-proof film and the can wall, which hinders the operation.
[0009]
The curing reaction can be prevented to some extent by a method of inserting a moisture absorbing material into the space inside the can and a method of filling an inert gas into the space, but slight moisture in the outside air invades due to fluctuations in the pressure inside the can due to long-term temperature differences. Therefore, curing cannot be prevented for a long period of time.
[0010]
In particular, when used as a sealing material to be used for filling joints or the like, the material is designed to have a high thixotropic property, and must be scraped off with a spatula or the like in order to take out the material from the inside. In this case, when a cured product is generated on a can wall or the like, there is a problem that workability is significantly impaired.
[0011]
[Means for Solving the Problems]
Therefore, as a result of diligent studies, the present inventors have found that after covering the surface with a moisture-proof film in the packaging of a metal can, it is possible to suppress the internal curing by encapsulating a specific curable composition in the voids. .
[0012]
In other words, after coating the surface with a moisture-proof film, by filling a specific material in the gap between the moisture-proof film and the can wall, the material cures, preventing the inside from hardening and removing the moisture-proof film. They peeled off the wall and removed it together with the moisture-proof film, and found that no cured product of the can wall remained.
[0013]
That is, in the present invention, a one-component moisture-curable composition is filled, and after covering the surface with a moisture-proof film, the package is sealed with a lid. The present invention relates to a one-component moisture-curable composition-filled packaging can, which is filled and cured with a curable composition containing a saturated hydrocarbon-based polymer having as a main component.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
The one-component moisture-curable composition in the present invention can be arbitrarily selected from urethane-based, modified silicone-based, modified silicone-epoxy-based compositions, etc., but in addition to moisture-curing properties, modified silicone-based compositions that hardly cause an increase in internal viscosity due to heating. A more remarkable effect can be obtained in the composition (1).
[0015]
The packaging can in the present invention can be arbitrarily selected from those having no moisture permeability such as ordinary tin cans or those having a very low moisture permeability. The can may be provided by packing the can lid or the like.
[0016]
The moisture-proof film may be any film as long as it has no or very little moisture permeation, and can be arbitrarily selected from various plastic films, a composite film in which two or more films are laminated, a metal-deposited film, and the like. From the viewpoint of low moisture permeability, ease of handling, and the like, an aluminum composite film obtained by laminating two or more films with a thermoplastic film / aluminum film or the like is preferable.
[0017]
In the present invention, the curable composition containing a reactive hydrocarbon group-containing saturated hydrocarbon-based polymer as a main component, which is filled in the gap between the moisture-proof film and the can wall, is a saturated hydrocarbon having a reactive silicon group. Polymer and, if necessary, plasticizer, filler, solvent, thixotropic agent, UV absorber antioxidant, silanol condensation catalyst, curing accelerator, curing retarder, adhesion promoter, dehydrating agent, and other additives Etc. can be used.
[0018]
The saturated hydrocarbon-based polymer having a reactive silicon group is a polymer in which a reactive silicon group is introduced into a polymer substantially containing no carbon-carbon unsaturated bond other than an aromatic ring. Examples of the polymer having substantially no carbon-carbon unsaturated bond include polyethylene, polypropylene, polyisobutylene, hydrogenated polybutadiene, hydrogenated polybutadiene, and the like. Specifically, Epion (manufactured by Kanegafuchi Chemical Industry Co., Ltd.) can be used.
[0019]
The one-component sealing material composition may be any one that can react and cure with moisture in the air, and can be a modified silicone composition containing an organic polymer having a reactive silicon group as a main component, a urethane prepolymer. And a polysulfide-based composition mainly containing a polysulfide polymer having an SS bond in the main chain. Among these, a modified silicone composition having excellent stability in a water-blocking state is preferable.
[0020]
The modified silicone composition is mainly composed of an organic polymer having a reactive silicon group, and if necessary, a plasticizer, a filler, a solvent, a thixotropic agent, an ultraviolet absorber antioxidant, a silanol condensation catalyst, A curing accelerator, a curing retarder, an adhesion-imparting agent, a dehydrating agent, and other additives can be used.
[0021]
The organic polymer having a reactive silicon group as a main component is an organic polymer that can be cross-linked by a silanol condensation reaction, and that forms a siloxane bond by condensation and turns into a resinous or rubbery organic polymer. .
[0022]
Examples of the organic polymer include a polyalkylene oxide having a reactive silicon group. Polyalkylene oxides having reactive silicon groups are cured by humidity in the air at room temperature, and the cured products have excellent flexibility, elongation properties, transparency and watertightness, making them ideal for sealing materials and adhesives. However, the present invention is not limited to this. Specific examples of the polyalkylene oxide having a reactive silicon group include MS polymer (manufactured by Kanegafuchi Chemical Industry Co., Ltd.) and Exester (manufactured by Asahi Glass).
[0023]
Examples of the plasticizer include phthalate esters such as dibutyl phthalate, diheptyl phthalate di (2-ethylhexyl) phthalate, butyl benzyl phthalate, diisononyl phthalate, and diisodecyl phthalate; epoxidized plasticizers; polyester plasticizers; polyethers; Chlorinated paraffins can be used.
[0024]
As the filler, calcium carbonate, mica, talc, clay, silica, glass balloon and the like can be used.
[0025]
Examples of the silanol condensation catalyst include titanates, tin carboxylate, a reaction product of dibutyltin and phthalate, dibutyltin bisacetoacetonate, an amine compound, a salt of an amine compound with a carboxylic acid, an amino group. Known catalysts such as a silane coupling agent having
The one-component modified silicone-based sealing material is obtained by mixing an organic polymer having a reactive silicon group, a plasticizer, a filler, a solvent, a thixotropic agent, an ultraviolet absorber, an antioxidant, and the like. After sufficiently dehydrating at a temperature of from 130 ° C. to 130 ° C., a silanol condensation catalyst, a stabilizer and the like are mixed and produced.
[0027]
The polyurethane-based sealing material is mainly composed of a urethane prepolymer having an isocyanate group at the terminal, and can use a plasticizer, a filler, a curing catalyst, a thixotropic agent, and the like.
[0028]
The one-component sealing material composition of the present invention is filled in a highly airtight container. At that time, in order to prevent curing during storage, a desiccant such as silica gel may be sealed and sealed.
[0029]
Next, a specific description will be given based on an embodiment.
