【0001】
【発明の属する技術分野】
本発明は、有機溶剤タイプの接着剤に関するものである。
【0002】
【従来の技術】
有機溶剤タイプの接着剤とは、接着機能を有する主体(プラスチック)を有機溶剤で溶解し、その有機溶剤の揮発により接着機能を発現するものである。よって、理論的には有機物質に溶解するものはすべて含まれることとなる。
【0003】
従来のこの種の接着剤としては、ウレタン系、酢酸ビニル系等種々のものがあり、これらの溶媒としてはトルエン、キシレン等の芳香族系溶媒、酢酸ブチル、酢酸エチル等のエステル系溶媒、MIBK(メチルイソブチルケトン)、MEK(メチルエチルケトン)等のケトン系のものが用いられている。
【0004】
溶媒の機能としては、主体を溶解すること、迅速に揮発することである。上記の従来の溶媒はこれらの点に関しては問題がなかった。
【0005】
【発明が解決しようとする課題】
しかし、溶媒としては上記の機能ばかりでなく、毒性がない(又は低い)こと悪臭がない、及び被接着物を溶解しない等も重要なポイントである。この観点から前記の溶媒を見ると、種々の欠点がある。
【0006】
例えば、ほとんどのものが毒性を有し狭い室内等で換気しながら用いる必要がある。また臭気が大きく不快感を与える。よって、これらのものを使用する作業者に不安感や危険意識を持たせ、適切な施工が難しくなったり、いたずらに工賃が向上したりしていた。
【0007】
さらに、この種の接着剤を多量に使用する床材の貼着等では、それに多用されているポリ塩化ビニルやゴムを溶解したり、伸長させてしまう。これを防止するには、塗布量や塗布温度、溶媒の量等を厳密に管理する必要があり、作業がより難しくなる。
【0008】
【課題を解決するための手段】
そこで、本発明者は上記諸点に鑑み鋭意研究の結果、本発明接着剤を完成したものであり、その特徴とするところは、ジメチルカーボネートを溶媒の主成分として床材用に用いる点にある。
【0009】
ジメチルカーボネートとは、化1で示される化合物であり、これ自体は公知のものである。
【化1】
これは、従来からカルボニル化剤、カルボメトキシ化剤、又はメチル化剤として使用されていたものであるが、その量は微々たるものであった。本発明では、これの性質を種々研究して本発明に到達したものである。また、溶剤としてはこのジメチルカーボネートのみでなく、混合物であってもよい。しかし、この化合物の利点を生かすためには、溶剤中に50%以上は含有していることが必要である。混合する溶媒としては、これと相溶性のあるものであるが、主体を溶解することも当然である。通常は、アセトンやキシレンが好適である。
【0010】
本発明に用いる接着剤の本体は、特別なものである必要はなく、上記したジメチルカーボネートに溶解するものであればどのようなものでも使用できる。例えば、ウレタン系、エポキシ系、酢酸ビニル系、変性酢酸ビニル系、合成ゴム系、アクリル系等である。
【0011】
ジメチルカーボネートの混合量は、通常の溶媒と同様でよく、その使用時の粘度等によって決めればよいが、通常は全量の20〜80%である。勿論、溶媒としてこのジメチルカーボネートのみでなく、他の溶媒と混合して用いてもよい。他の溶媒は溶解するものならどのようなものでもよいが、例えば、アルコール、エステル、ケトン、芳香族炭化水素系のもの等である。
【0012】
【発明の実施の形態】
以下本発明を、実施例に基づきより詳細に説明する。
実施例
公知の合成方法に従って、ポリブチレンアジペートジオール(分子量=2000)200gと、ポリプロピレングリコール(分子量=2000)200g及びネオペンチルグリコール83.2gを混合し、そこにトルエンジイソシアネート209gを投入し、80℃にて5時間反応させた。次いで、ジメチルカーボネート461gを用いて希釈して、固形分60%、粘度3000cpsのイソシアネート含有ポリウレタン樹脂Aを得た。
【0013】
比較例
ジメチルカーボネートの代わりにトルエン、酢酸エチルを用いて実施例と同様にして希釈してそれぞれイソシアネート含有ポリウレタン樹脂B、Cとした。粘度は、それぞれ5000cps、2500cpsであった。
【0014】
実施例と比較例をポリ塩化ビニルの接着を例にとって種々の点において比較した。評価方法は、900mm角のスレート板、鉄板を下地としてこの上にイソシアネート含有ポリウレタン樹脂A、B、Cを300g/m2 塗布し、すぐに300mm角のゴムタイル、ホモジニアスタイルを隙間なく貼りつけ、24時間後の変化を調べた。
【0015】
結果を表1に示す。
【表1】
【0016】
【発明の効果】
表1の結果から、本発明の接着剤は、溶媒としてジメチルカーボネートを用いているため、被接着体への影響がなく、人体への毒性も、臭気もない。
の汚染の心配がない。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an organic solvent type adhesive.
[0002]
[Prior art]
The organic solvent type adhesive is a substance in which a main body (plastic) having an adhesive function is dissolved in an organic solvent and the adhesive function is exhibited by volatilization of the organic solvent. Therefore, theoretically, anything that dissolves in an organic substance is included.
[0003]
Conventional adhesives of this type include various types such as urethane and vinyl acetate. These solvents include aromatic solvents such as toluene and xylene, ester solvents such as butyl acetate and ethyl acetate, MIBK. Ketones such as (methyl isobutyl ketone) and MEK (methyl ethyl ketone) are used.
[0004]
The function of the solvent is to dissolve the main body and to volatilize quickly. The conventional solvent described above has no problem in these respects.
[0005]
[Problems to be solved by the invention]
However, as a solvent, not only the above-mentioned function, but also the important point is that it is not toxic (or low), has no foul odor, and does not dissolve the adherend. From this point of view, the above solvents have various disadvantages.
[0006]
For example, most of them are toxic and need to be ventilated in a small room. In addition, the odor is large and uncomfortable. Therefore, anxiety and danger consciousness were given to the workers who use these things, and proper construction became difficult, and wages were unnecessarily improved.
[0007]
Furthermore, in the pasting of floor materials that use a large amount of this type of adhesive, polyvinyl chloride and rubber that are frequently used in the adhesive are dissolved or stretched. In order to prevent this, it is necessary to strictly control the coating amount, the coating temperature, the amount of the solvent, etc., and the work becomes more difficult.
[0008]
[Means for Solving the Problems]
Accordingly, the present inventors as a result of intense research in view of the above described aspects, which has completed the present invention the adhesive, and it is characterized, the dimethyl carbonate to the point used as the main component of the solvent for flooring is there.
[0009]
Dimethyl carbonate is a compound represented by Chemical Formula 1, and is known per se.
[Chemical 1]
This is conventionally used as a carbonylating agent, carbomethoxylating agent, or methylating agent, but the amount thereof was insignificant. In the present invention, the present invention has been achieved through various studies on the properties thereof. Moreover, as a solvent, not only this dimethyl carbonate but a mixture may be sufficient. However, in order to take advantage of this compound, it is necessary to contain 50% or more in the solvent. The solvent to be mixed is compatible with this, but it is natural to dissolve the main body. Usually, acetone or xylene is suitable.
[0010]
The main body of the adhesive used in the present invention does not need to be special, and any material can be used as long as it can be dissolved in the dimethyl carbonate. For example, urethane, epoxy, vinyl acetate, modified vinyl acetate, synthetic rubber, acrylic, and the like.
[0011]
The amount of dimethyl carbonate mixed may be the same as that of a normal solvent, and may be determined by the viscosity at the time of use, but is usually 20 to 80% of the total amount. Of course, not only this dimethyl carbonate but also other solvents may be used as a solvent. Any other solvent may be used as long as it dissolves, and examples thereof include alcohols, esters, ketones, and aromatic hydrocarbons.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail based on examples.
Example According to a known synthesis method, 200 g of polybutylene adipate diol (molecular weight = 2000), 200 g of polypropylene glycol (molecular weight = 2000) and 83.2 g of neopentyl glycol were mixed, and 209 g of toluene diisocyanate was added thereto, and 80 ° C. For 5 hours. Subsequently, it was diluted with 461 g of dimethyl carbonate to obtain an isocyanate-containing polyurethane resin A having a solid content of 60% and a viscosity of 3000 cps.
[0013]
Comparative Example Diluted in the same manner as in Example using toluene and ethyl acetate instead of dimethyl carbonate to obtain isocyanate-containing polyurethane resins B and C, respectively. The viscosities were 5000 cps and 2500 cps, respectively.
[0014]
Examples and comparative examples were compared in various respects by taking the adhesion of polyvinyl chloride as an example. The evaluation method is as follows. Using a 900 mm square slate plate and an iron plate as a base, 300 g / m 2 of isocyanate-containing polyurethane resins A, B, and C are coated thereon, and a 300 mm square rubber tile and a homogeneous style are immediately pasted without gaps. Changes after time were examined.
[0015]
The results are shown in Table 1.
[Table 1]
[0016]
【The invention's effect】
From the result of Table 1, since the adhesive agent of this invention uses dimethyl carbonate as a solvent, there is no influence on a to-be-adhered body, neither a toxicity to a human body nor an odor.
There is no worry of contamination.
