Abstract

The invention discloses an amino-terminated polyether compound containing a cardanol derivative, and a preparation method and application of the amino-terminated polyether compound containing a cardanol derivative. The amine-terminated polyether compound containing a cardanol derivative is used for curing epoxy resin, the activity ability of epoxy resin chain segments can be improved, the stress relaxation time of the chain segments is shortened, the dependence on the external force response rate is reduced, and a cured product has high bonding strength and excellent toughness. The amino-terminated polyether compound containing the cardanol derivative is novel and unique in structure, non-toxic and low in production cost.

Description

technical field [0001] The invention relates to the field of synthesis of polyether amine compounds, in particular to an amino-terminated polyether compound containing cardanol derivatives, a preparation method and an application thereof. Background technique [0002] Epoxy resins are an important class of thermosetting resins, which have excellent mechanical properties, bonding properties, electrical insulation properties, chemical corrosion resistance and dimensional stability, and are used in adhesives, protective coatings, electrical insulation materials and high-performance Composite materials and other fields have a wide range of applications. However, due to its high cross-linking structure, there are defects such as high brittleness, poor impact resistance, poor heat resistance and fatigue resistance, which limit its application. Therefore, improving its toughness has always been a hot spot in modification research. [0003] Materials fail when subjected to high loa...
