Description

本発明は、低温硬化注入剤組成物に関するものである。   The present invention relates to a low temperature cure injectable composition.

土木建築において、集成材、LVL等の木質構造材料が使用されるが、大型構造物においては波板鋼板とボルト或いはラグスクリュー等を用いて部材間の接合がなされ、隙間には接合樹脂としてエポキシ樹脂が粘度、非加熱硬化、接着性の点で注入されている。しかし、この作業は屋外において行われ、冬期は氷点下の環境で、強度を出すことが要求される。
従来、低温での硬化速度を高める方法としては、アクリロイル基を有する化合物の添加やメルカプト基を有する硬化剤を使用が提案されているが、前者はポットライフの延長に難があり、後者は臭気等の問題を有していた。
In civil engineering and construction, wood-structured materials such as laminated timber and LVL are used. In large structures, members are joined using corrugated steel plates and bolts or lag screws, and epoxy is used as a joining resin in the gaps. Resin is injected in terms of viscosity, non-heat curing, and adhesiveness. However, this work is performed outdoors, and it is required to increase the strength in a sub-freezing environment in winter.
Conventionally, as a method for increasing the curing rate at low temperature, the addition of a compound having an acryloyl group or the use of a curing agent having a mercapto group has been proposed, but the former has difficulty in extending pot life, and the latter has an odor. Had problems such as.

解決しようとする課題は、0℃以下でも硬化し実用強度に到達し、可使時間を有し、低温でも注入可能な粘度であるエポキシ樹脂組成物を供することである。   The problem to be solved is to provide an epoxy resin composition that cures even at 0 ° C. or lower, reaches practical strength, has a pot life, and has a viscosity that can be injected even at low temperatures.

本発明のエポキシ樹脂組成物は0℃以下の屋外環境下で注入硬化でき、大型構造物の部材移動・設置等に必要な強度が短期間で得られるという利点がある。   The epoxy resin composition of the present invention has the advantage that it can be injected and cured in an outdoor environment of 0 ° C. or less, and the strength required for moving and installing members of a large structure can be obtained in a short period of time.

本発明は2液型エポキシ樹脂にスチレン化フェノールを含むことを特徴とする組成物であり、冬期屋外等で、樹脂を保温注入後、放熱により、硬化温度が0℃を上回らない環境でも、次工程に進める強度が得られるものである。具体的には木質材料による大型構造物の結合に波板鋼板と木質材料に穴を設け、ボルトを挿入し、隙間にはエポキシ樹脂組成物を注入するものであるが、大型構造物故に保温ができず、容易に次工程に進めることができなかった。次工程とは、これらを移動し、組み付けることで、本発明ではこれに耐える強度を発現するもので、後記0℃以下7サイクルで圧縮強度50MPaとした。
スチレン化フェノールはフェノールに1モルのスチレンを付加させたもの、2モル以上付加させたものがある。精製したもの以外 1モル付加物である(α−ベンジル)フェノールが主成分となる。エポキシ樹脂組成物全体に対して 1〜3重量%で効果を奏する。
The present invention is a composition characterized by containing a styrenated phenol in a two-pack type epoxy resin. Even in an environment where the curing temperature does not exceed 0 ° C. due to heat dissipation after insulative injection of the resin in the winter outdoors, etc. The strength advanced to the process can be obtained. Specifically, a corrugated steel sheet and a wood material are provided with a hole in a large structure made of wood material, a bolt is inserted, and an epoxy resin composition is injected into the gap. It was not possible to proceed to the next process easily. In the next step, these are moved and assembled, and in the present invention, a strength that can withstand this is developed. The compression strength is 50 MPa in 7 cycles below 0 ° C.
Styrenated phenols include those obtained by adding 1 mol of styrene to phenol and those added by 2 mol or more. The main component is (α-benzyl) phenol, which is a 1-mol adduct other than the purified product. The effect is exhibited at 1 to 3% by weight based on the entire epoxy resin composition.
