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 ...

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.

Example Embodiment

[0033] Example 1

[0034] The octaaminophenyl POSS (OAPS) is reacted with a quantitative p-toluenesulfonic acid in a molar ratio in a THF solution. The molar ratio of the amino group to the sulfonic acid group is 1/1 to generate cage octaaminophenyl silsesquioxane After separation, washing and drying of p-toluenesulfonate (OPAAS), the yield was 95.4%.

Example Embodiment

[0035] Example 2

[0036] The octaaminophenyl POSS (OAPS) is reacted with quantitative p-toluenesulfonic acid at molar ratio in THF solution, wherein the molar ratio of amine group to sulfonic acid group is 1/2 to form cage octaaminophenyl silsesquioxane After separation, washing and drying of p-toluenesulfonate (OPAAS), the yield was 95.7%.

Example Embodiment

[0037] Example 3

[0038] The octaaminophenyl POSS (OAPS) is reacted with a quantitative amount of methanesulfonic acid in a molar ratio in a THF solution, and the molar ratio of the amine group to the sulfonic acid group is 1/1 to form cage octaaminophenyl silsesquioxane Methanesulfonate (OAPS-MS) has a yield of 94.1% after separation, washing and drying.
