Embodiment 1

[0016] I. the synthesis of formula 1 compound

[0017]

Synthetic example

[0018] 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:

[0019] 1.6 mol of dimethyladamantane and 1 mol of maleic anhydride were added to the reaction vessel, and the temperature inside the reaction vessel was maintained at 160°C. In this reaction vessel, a solution obtained by dissolving 5.5 mmol of di-tert-butyl peroxide as a radical generating agent in a small amount of dimethyladamantane was added dropwise over 3 hours to perform a reaction. The reaction was terminated after 3 hours from the completion of the dropwise addition, and a reaction product was obtained. The resulting reaction product was distilled under reduced pressure to obtain the corresponding target compound.

Abstract

The invention discloses a curing agent composition. The curing agent composition has the beneficial effect that the Tg value of the curing agent composition is increased under the premise that the usage amount is not changed by compounding two different types of curing agents.

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...
