Embodiment 1

[0013] I. the synthesis of formula 1 compound

[0014]

Synthetic example

[0015] The compound described in Formula 1 is a known compound, which can be purchased commercially or prepared synthetically by those skilled in the art. Its typical but non-limiting synthetic examples are as follows:

[0016] First, in a reaction container, 1 mol of maleic anhydride is added to 1.6 mol of dimethyladamantane or ethyl adamantane, and the internal temperature of the reaction container is kept at about 160°C. Next, a solution obtained by dissolving 5.5 mmol of di-tert-butyl peroxide in a small amount of dimethyladamantane or ethyladamantane as a radical generating agent is added dropwise to the reaction vessel over about 3 hours. The reaction was terminated in about 3 hours from the end of the dropwise addition to obtain a reaction product. The corresponding target substance was obtained by distilling the obtained reaction product under reduced pressure. However, the feed ratio, reaction temperature, and reaction time shown here can be appropriately changed so...

Abstract

The invention discloses a curing agent combination. Through compounding of two different types of curing agents, a Tg value is improved under this premise of no change of a use amount.

Description

technical field [0001] The present invention relates to a curing agent composition. Background technique [0002] Curing agent, also known as hardening agent, curing agent or stabilizer, is a kind of substance or mixture that promotes or controls the curing reaction. Resin curing is through chemical reactions such as condensation, ring closure, addition or catalysis, so that the thermosetting resin undergoes an irreversible change process, and curing is completed by adding a curing (crosslinking) agent. Curing agent is an essential additive, whether it is used as adhesives, coatings, or castables, it is necessary to add a curing agent, otherwise the epoxy resin cannot be cured. [0003] The curing reaction is a chemical reaction, which is greatly affected by the curing temperature. As the temperature increases, the reaction speed is accelerated and the gel time is shortened; the logarithmic value of the gel time generally shows a linear downward trend with the increase of t...
