Problems solved by technology

However, benzoxazine resins also have disadvantages, such as low molecular weight of the polymer, high curing temperature, low crosslinking density, brittleness, poor toughness, etc. The methods reported in existing documents and patents are all aimed at benzoxazine resins. These shortcomings of oxazine have made a series of improvement research
[0006] None of the current studies have involved cage-type silsesquioxanes containing ammonium sulfonate for benzoxazine / bisoxazoline resins, benzoxazine / epoxy resins, benzoxazine / epoxy resins / dioxanes, etc. Modification of thermosetting resin composition such as oxazoline

Abstract

The invention provides a cage type silsesquioxane sulphonate with potential catalytic action and a thermosetting resin composite thereof, in particular to a cage type oligomeric silsesquioxane containing ammonium sulphonate and the thermosetting resin composite obtained by mixing the cage type oligomeric silsesquioxane containing the ammonium sulphonate with thermosetting resins such as benzoxazine, oxadiazoline, an ethoxyline resin and a composition of the benzoxazine, the oxadiazoline and the ethoxyline resin. The obtained thermosetting resin composite can be solidified under lower temperature, and an obtained solidified product has higher modulus and better heat resistance.

Description

technical field [0001] The invention relates to a class of cage-type silsesquioxane sulfonate with latent catalytic effect and a thermosetting resin composition thereof. In particular, it relates to cage oligomeric silsesquioxanes containing ammonium sulfonates and the use of such silsesquioxanes with thermosetting resins such as benzoxazines, bisoxazolines, epoxy resins and combinations thereof The obtained thermosetting resin composition after mixing; the obtained thermosetting resin composition can be cured at a lower temperature, and the obtained cured product has a higher modulus and better heat resistance. Background technique [0002] Polyhedral Oligomeric Silsesquioxane (Polyhedral Oligomeric Silsesquioxane, POSS) monomer is currently the only organic-inorganic hybrid nanochemical filler, which not only combines the superior properties of organic components and inorganic components, but also has The new performance produced by the synergistic effect of the two. Its...
