Definitions
- the present invention relates to epoxy-based compositions.
- the reaction between the epoxy resin and the curing agent is exothermic, so a large amount of heat is released.
- the heat generated during the reaction causes shrinkage of the cured product obtained by curing the epoxy resin, and causes problems such as deterioration of the dimensional accuracy of the cast product and the occurrence of cracks in the cast product.
- the heat generated during the reaction between the epoxy resin and the curing agent causes deterioration of the mold that supplies the epoxy resin and other materials embedded in the epoxy resin.
- heat generation causes distortion of the housing and damage to the hollow fiber membranes, resulting in a significant reduction in the inherent filtering ability of the hollow fiber membranes. .
- the epoxy resin will partially decompose, resulting in discoloration or deterioration of the epoxy resin.
- the epoxy resin is carbonized or scorched, and there is a risk that the epoxy resin may ignite.
- the heat generated in mass casting cannot be efficiently released to the outside due to poor heat transfer in the bulk matrix. For this reason, for example, the curing reaction between the epoxy resin and the curing agent is carried out slowly over a long period of time to moderate heat generation, the reaction temperature and time during the curing reaction are strictly controlled, and casting is performed in multiple stages. It is necessary to perform a complicated process such as the above, and there is a problem that the production efficiency is lowered.
- the heat generated during the curing reaction is due to the reaction between the epoxy resin and the curing agent, so heat generation can be reduced by reducing the number of reactions per unit volume.

・反応促進剤(トリエタノールアミン、ジャパンケムテック社製 商品名「TEA99」)
表1~3に示した量を有するエポキシ樹脂を主剤とした。表1~3に示した所定量の反応性アミン化合物(B)、反応促進剤(D)及び触媒化合物(C)をインペラ型混合攪拌機に供給して均一に混合して硬化剤を作製した。なお、触媒化合物(C)が混合時に固体である場合、反応性アミン化合物(B)を80~110℃に加熱した上で、反応性アミン化合物(B)に触媒化合物(C)を供給して溶解させることによって、反応性アミン化合物(B)、反応促進剤(D)及び触媒化合物(C)を均一に混合した。上述の如くして製造した主剤及び硬化剤を含む二液型のエポキシ系組成物を製造した。
初期温度23℃のエポキシ系組成物の主剤と硬化剤を均一に混合した上で、23℃の雰囲気下にて直径140mm、高さ160mmのスチール缶にエポキシ系組成物を表1~3に示した注型量だけ流し込んだ。流しこんだエポキシ系組成物の中心部に熱伝対(K φ0.32、JIS C1602準拠)を入れ、データロガー(グラフテック社製 商品名「GL220」)を用いてエポキシ系組成物の硬化時の最高温度(硬化時の発熱)を測定した。エポキシ系組成物の主剤と硬化剤を混合してからエポキシ系組成物が最高温度を示すまでに要した時間を測定し、この時間を硬化時間とした。
硬化時の発熱を測定する要領と同一の要領でエポキシ系組成物を硬化させ、エポキシ系組成物の硬化時の最高温度を示した時点から24時間経過した後における硬化物について、JIS K6253に準拠した方法で25℃雰囲気下にて、タイプDデュロメータデュロメータを用いて硬度を測定した。なお、測定時間は30秒とした。なお、エポキシ系組成物が硬化しなかった場合は「未硬化」と記載した。
本出願は、2021年3月1日に出願された日本国特許出願第2021-31505号に基づく優先権を主張し、この出願の開示はこれらの全体を参照することにより本明細書に組み込まれる。
