Abstract

The invention provides a preparation method and application of benzoxazine capable of being rapidly photo-cured and photo-cured benzoxazine resin, and belongs to the technical field of preparation, manufacturing and application of benzoxazine. Through design and preparation of a molecular structure, an active double bond is introduced into two ends of the benzoxazine molecular structure or into the benzoxazine molecular structure through grafting modification of diamine and methacrylic acid isocyanate or acrylic acid isocyanate, so that the photosensitivity and the rapid presetting function of the benzoxazine are realized; the inherent ring-opening curing capacity and excellent comprehensive performance of the benzoxazine are kept, the rapid preforming and intelligent manufacturing capacity of the benzoxazine is also endowed, and the technical problem that secondary processing of existing benzoxazine is difficult to directly realize in complex parts, miniature parts, precision manufacturing and the like is solved; and the application of the material in the technical fields of 5G communication, additive manufacturing, photocuring coatings and the like is expanded.

Description

technical field

[0001] The present invention relates to the technical field of preparation of high-performance benzoxazine intermediates and rapid prototyping and manufacturing applications, in particular to a preparation method and application of a rapid photocurable benzoxazine, a photocurable benzoxazine resin, through molecular structure The innovative design expands the processing and molding methods of benzoxazine and its application and development in key technical fields such as light-cured coating, 3D printing, precision component manufacturing, and 5G copper-clad laminate resin. Background technique

[0002] Benzoxazine is a kind of intermediate containing heterocyclic structure synthesized from phenols, aldehydes and primary amines. It is a kind of compound with excellent heat resistance, flame retardancy, insulation and physical and mechanical properties. Resin with great application prospect. Because benzoxazine does not release low-molecular substances during ...
