Abstract

The invention relates to a furfurylamine type benzoxazine resin / maleimide compound composition, which is prepared from furfurylamine type benzoxazine resin and a series of maleimide group-containing compounds. The composition can be cured at lower temperature and used in a plurality of fields of coatings, thermosetting plastics, substrate resin of composite materials, and the like.

Description

technical field [0001] The present invention relates to a furfurylamine type benzoxazine resin / maleimide compound composition. Specifically, the present invention relates to a composition obtained by blending a furfurylamine-type benzoxazine resin and a maleimide compound, and a composition prepared by mixing the composition with other thermosetting resins. Background technique [0002] Benzoxazines are intermediates of a class of six-membered heterocyclic compounds composed of nitrogen and oxygen atoms synthesized from phenolic compounds, aldehydes and primary amine compounds. Cyclopolymerization produces nitrogen-containing networks similar to phenolic resins, called benzoxazine resins. In addition to the excellent properties of traditional phenolic resins such as high heat resistance, flame retardancy, excellent electrical and chemical properties, low water absorption, and low cost, benzoxazine resin does not release small molecules during the curing process. Zero shrin...
