Embodiment
[0046] The present invention will be described in more detail below through specific examples, but the present invention is not limited to these examples. The resin compositions and comparative examples were evaluated by the following characterization methods.
[0047] (1) Glass transition temperature test
[0048] Using dynamic thermomechanical analysis (Q800-DMA, manufactured by TA Company in the United States), a 60mm*5mm*2mm cured resin sample is used at an amplitude of 9um, a frequency of 1HZ, and a range of 30-350°C at 5°C / min. Its temperature rises to obtain the maximum value of tanδ as its glass transition temperature.

The invention aims to provide an adamantane derivative, its preparation method and an application of a derivative containing the adamantane structure in epoxy resin. the invention mainly includes an application of the above adamantane derivative in curing epoxy resin and raising properties of epoxy resin, such as moisture and heat resistance, dielectric property, weatherability, heat stability, oxidation resistance, organic solvent corrosion resistance and the like, such that the adamantane derivative has a wide range of application. Through repeated researches, the inventor finds out that the derivative containing the adamantane structure can remarkably enhance properties of epoxy resin, such as moisture and heat resistance, dielectric property, heat stability, ageing resistance and the like, when used as a curing agent to be connected to epoxy resin.
Description
[0001] technology neighborhood [0002] The present invention relates to the synthesis of phenol and amine derivatives containing adamantane structure and the application of the adamantane derivatives in resin. Background technique [0003] Adamantane is a highly symmetrical cage-like hydrocarbon, and its basic carbon skeleton is a ring-shaped tetrahedron composed of three cyclohexanes with chair conformation characteristics, which is similar to a lattice unit of diamond; since adamantane It has a high degree of symmetry in the structure, which enables it to be tightly packed in the crystal lattice, so the structure of adamantane has considerable stability, and its melting point reaches 205-210 ° C. At the same time, the adamantane molecule only contains two kinds of carbon atoms, namely tertiary carbon Unlike secondary carbons, the chemical properties of adamantane are mainly manifested by the reaction with hydrogen on this carbon. Among them, the hydrogen atoms on the four ...
