物の場合などにおいては、硬化性と貯蔵安定性とを両立
し得るものがない等の問題点を有している。Structures of conventional examples and their problems Conventionally, amines, acid anhydrides, etc. have been often used as curing agents for epoxy resin compositions, but epoxy resin compositions containing such curing agents have no adhesive properties.・There are problems such as insufficient strength, and especially in the case of molding compositions and integrated powder compositions, there is no material that can achieve both curability and storage stability. There is.
例えば、エポキシ樹脂を接着剤として用いる時その硬化

温かつ長時間全必要とする等の欠点があった。For example, when epoxy resin is used as an adhesive, dicyandiamide is often used as a curing agent. Although this system has excellent adhesive strength and storage stability, the curing reaction requires, for example, 180°C/2 hours. However, it has drawbacks such as requiring high temperatures and long periods of time.
発明の目的
本発明は、以上のような欠点を改良し、接着力が高く、
貯蔵安定性に優れ、かつ低温度硬化の可能な、−散型ま

Bisphenol A type (or F type) epoxy resin (hereinafter referred to as Resin A and Resin B, respectively) represented by the general formula in which R is a hydrogen atom or a methyl group. A phenol novolac (or cresol novolac) type epoxy resin (hereinafter each abbreviated as resin C1 resin) represented by the formula (in which R is a hydrogen atom or a methyl group) Dicyandiamide (hereinafter abbreviated as DICY) and imidazole (hereinafter R is a hydrogen atom or a methyl group) represented by the formula (wherein R1 represents a hydrogen atom or a methyl group and R2 represents an alkyl group having 1 to 17 carbon atoms). When R2 has 11 carbon atoms, 1c11Z, R1 is a hydrogen atom, and R2 has 17 carbon atoms.
In the above, resins A and C are liquid or solid, resin B is liquid, and resin is solid. The curing agents C11Z and C1□Z are
DICY is 4 to 20 parts by weight for 100 parts by weight of resins A, B, C, and D, either alone or in combination of two or more, which are commercially available from Shikoku Kasei Kogyo Co., Ltd. under the same name. C11Z and C1□Z are blended in an amount of 1 to 10 parts.

) By adding C11Z and C1□zl as curing accelerators, an epoxy resin composition with high adhesive strength even when cured at a low temperature and in a short time can be obtained, compared to a case where ICYi is blended alone. Furthermore, when using the present epoxy resin composition as a powder coating or adhesive, the addition of C11Z and C1□Z improves the flow of the resin composition after it has been softened, allowing the adherend to adhere well. There is also the effect of being covered by the agent composition.
