Embodiment 1

[0016] I. Synthesis of compound of formula 1

[0017]

Synthetic example

[0018] The compound described in Formula 1 is a known compound, and those skilled in the art can purchase it commercially or synthetically. A typical but non-limiting example of synthesis is as follows:

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

[0020] II. Synthesis of compound of formula 2

[0021]

[0022] The compound is a known compound, and those skilled in the art can purchase it commercially or synthetically. A typical bu...

Abstract

The invention discloses a curing agent composition. The Tg value of the curing agent composition is improved through compounding of different types of two curing agents on the premise that the dosage is invariable.

Description

Technical field [0001] The invention relates to a curing agent composition. Background technique [0002] Curing agent, also known as hardener, curing agent or setter, is a type of substance or mixture that promotes or controls the curing reaction. Resin curing is the process of irreversible changes to thermosetting resins through chemical reactions such as condensation, ring closure, addition or catalysis. The curing is completed by adding a curing (crosslinking) agent. Curing agent is an indispensable additive, no matter it is used as adhesive, coating, castable, curing agent must be added, otherwise the epoxy resin cannot be cured. [0003] The curing reaction is a chemical reaction, which is greatly affected by the curing temperature. The higher the temperature, the faster the reaction speed, and the shorter the gel time; the logarithmic value of the gel time generally decreases with the increase of the curing temperature. However, if the curing temperature is too high, the p...
