Description
【0001】
【発明の属する技術分野】
本発明は、土木建築分野において、硬化物の樹脂強度の大きい注入剤や接着剤に関する。
【0002】
【従来の技術】
従来、土木建築分野において接着や注入を行う場合には、エポキシ系室温硬化型接着剤が用いられてきた。しかしながら、エポキシ系室温硬化型接着剤は低温硬化性に劣ったり、人体に対して変異原生やかぶれを生じてしまうという欠点があった。
これらの欠点を解決するものとして、アクリル系樹脂を使用した接着剤や注入剤が開発されている。アクリル系樹脂はエポキシ系樹脂に比べて硬化時間が早い等の理由から徐々にではあるが使用されつつある。
【0003】
しかしながら硬化物の樹脂強度が小さいという欠点があり、エポキシ系樹脂に比べて土木建築分野での利用は進まなかった。
硬化物の樹脂強度を向上したアクリル系樹脂としては、エポキシ基を有する化合物と(メタ)アクリル酸を反応させたエポキシアクリレート、ジシクロペンテニルエチルアクリレート及びヒドロキシアルキルメタクリレートといった3成分系の硬化性樹脂組成物(特開平5―17545号参照)や、ビスフェノールAジエチレングリコールジメタクリレートとヒドロキシアルキルメタクリレートを含有する硬化性樹脂組成物(特開平8−127509号参照)が提案されている。
【0004】
【発明が解決しようとする課題】
しかしながら、これらの硬化性樹脂組成物は、夏の直射日光下といった、40〜80℃の高温下での耐水性が不十分なため、夏季降雨後の直射日光下等といった高温で湿度の高い所では硬化性樹脂組成物の接着性が小さくなるという課題があった。又、コンクリートへの接着剤や注入剤に使用した場合、コンクリート中に含有する水酸化カルシウムといったアルカリ性化合物が存在すると、アクリル系樹脂組成物が硬化しにくくなるという課題があった。
本発明者は、鋭意検討を重ねた結果、ある特定の硬化性樹脂組成物を使用することにより、上記課題を解決できる知見を得て本発明を完成するに至った。
【0005】
【課題を解決するための手段】
即ち、本発明は、(1)一般式(ア)で示されるビスフェノール骨格を有するジ(メタ)アクリレート、
【化3】
(2)一般式(イ)で示されるジシクロペンテニルオキシアルキレン(メタ)アクリレート、
【化4】
及び(3)ヒドロキシアルキル(メタ)アクリレートを含有してなる硬化性樹脂組成物を含有してなるコンクリート用補修剤であり、さらに、前記硬化性樹脂組成物が(4)有機過酸化物と(5)分解促進剤を含有してなる前記のコンクリート用補修剤である。又、前記コンクリート用補修剤を使用してなることを特徴とするコンクリートの補修方法である。
【0006】
【発明の実施の形態】
以下、本発明を詳細に説明する。
【0007】
本発明で使用する(1)ビスフェノール骨格を有するジ(メタ)アクリレートとは、ビスフェノール骨格の末端にオキシアルキレングリコールを介し、(メタ)アクリル基を2個有するジ(メタ)アクリレートをいい、以下の一般式(ア)で示されるものをいう。成分(1)は、耐水性、耐熱性、及び樹脂強度の向上という効果を有する。又、成分(1)は、エポキシ(メタ)アクリレートと異なり、水酸化カルシウムといったアルカリ性化合物が存在しても、硬化阻害を受けないという効果を有する。
【0008】
【化5】
【0009】
成分(1)としては、NKエステルBPE−100(新中村化学工業株式会社製)、NKエステルBPE−200(新中村化学工業株式会社製)、NKエステルBPE−500(新中村化学工業株式会社製)、NKエステルBPE−1300(新中村化学工業株式会社製)、ライトエステルBP−2EMBR−MA(共栄社化学株式会社)等が挙げられる。これらの1種又は2種以上を使用することができる。これらの中では、硬化物の樹脂強度が大きい点で、BPE−200(R1 、R1’はメチル基、R2 、R2’はエチレン基、m+n=4)が好ましい。
R1 、R1’は、疲労試験による耐久性向上の点で、メチル基が好ましい。
R2 、R2’は、高温下での耐水性、硬化物の樹脂強度及び経済性の点で、1〜4個の炭素原子を有するアルキレン基が好ましく、エチレン基がより好ましい。m+nは、硬化物の樹脂強度が大きい点で、3〜8が好ましく、4がより好ましい。
【0010】
成分(1)の使用量は、(1)、(2)及び(3)の合計100重量部中、20〜80重量部が好ましく、30〜70重量部がより好ましい。20重量部未満だと硬化物の樹脂強度が低下するおそれがあり、80重量部を越えると表面硬化性が低下するおそれがある。
【0011】

【0035】
本発明において、硬化性樹脂組成物は通常、成分(1)〜(5)を室温下で撹拌混合して使用する。撹拌混合の際に無機充填剤を添加してもよい。硬化性樹脂組成物は1液型や2液型として使用できる。1液型として使用する場合には、成分(1)〜(4)を予め混合しておき、例えばコンクリート用補修剤として使用する際に成分(5)を混合する方法や、成分(1)〜(3)及び(5)を予め混合しておき、実際に使用する際に成分(4)を混合する方法等が挙げられる。2液型として使用する場合には、成分(1)〜(3)を混合したものを2液に分け、一方の液に成分(4)を、もう一方の液に成分(5)を添加しておき、例えばコンクリート用補修剤として使用する際に、2液を混合する方法等が挙げられる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an injection or adhesive having a high resin strength of a cured product in the field of civil engineering and construction.
[0002]
[Prior art]
Conventionally, when bonding or pouring is performed in the field of civil engineering and construction, an epoxy-based room temperature-curable adhesive has been used. However, the epoxy room temperature-curable adhesive has a drawback that it is inferior in low-temperature curability and causes mutagenicity and rash on the human body.
To solve these drawbacks, adhesives and injections using acrylic resins have been developed. Acrylic resins are gradually being used because they have a faster curing time than epoxy resins.
[0003]
However, there is a drawback that the resin strength of the cured product is low, and its use in the field of civil engineering and construction has not progressed as compared with epoxy resins.
Acrylic resins with improved resin strength of cured products include three-component curable resin compositions such as epoxy acrylate, dicyclopentenylethyl acrylate, and hydroxyalkyl methacrylate obtained by reacting a compound having an epoxy group with (meth) acrylic acid. (See JP-A-5-17545) and a curable resin composition containing bisphenol A diethylene glycol dimethacrylate and hydroxyalkyl methacrylate (see JP-A-8-127509).
[0004]
[Problems to be solved by the invention]
However, these curable resin compositions have insufficient water resistance at a high temperature of 40 to 80 ° C., such as under direct sunlight in summer, and therefore have a high humidity and high temperature, such as under direct sunlight after summer rain. However, there is a problem that the adhesiveness of the curable resin composition is reduced. In addition, when used as an adhesive or a pouring agent for concrete, if an alkaline compound such as calcium hydroxide contained in concrete is present, there is a problem in that the acrylic resin composition is hardly cured.
As a result of intensive studies, the present inventor has obtained knowledge that can solve the above-mentioned problems by using a specific curable resin composition, and has completed the present invention.
[0005]
[Means for Solving the Problems]
That is, the present invention provides (1) a di (meth) acrylate having a bisphenol skeleton represented by the general formula (A):
